Consider These 6 Points Before Buying a Marine Aquarium Cleanup Crew

Marine aquarium cleanup crews (CUC)—those combo packs of various snails, crabs, and echinoderms sold for the purpose of algae control and detritus elimination—can serve an excellent utilitarian function in a saltwater system. What’s more, in addition to the janitorial duties they perform, many of these invertebrates are fascinating to observe in their own right and add yet another layer of enjoyment to the hobby.

Hermits crabs are a common saltwater aquarium cleanup crew member. Pictured is an Electric Blue Hermit (Calcinus elegans).

However, any time you introduce livestock to an aquarium, there are compatibility issues, long-term care requirements, and other factors to think about. So, before investing your hard-earned dollars in any combination of critters to clean your aquarium, consider the following six points:

#1 Cleanup crews are just part of the solution

Cleaner organisms can certainly do their part to help keep irksome algae under control and scavenge uneaten food and detritus from those tight nooks and crannies, but they’re only part of the solution. You still have to do your part to minimize nutrient import and maximize its export by:

In other words, a cleanup crew is no substitute for good-old-fashioned “elbow grease.”

#2 Know what’s in the mix

Critter assemblages can vary considerably from one company’s cleanup crew to the next. Before committing to one, be sure to identify exactly which species are included in the package and thoroughly research their characteristics and care requirements—just as you would when adding a fish or coral to your tank. You want to verify that:

  • You can meet the long-term needs of all the species in the package.
  • All the species in the crew will be incompatible with your current livestock (e.g. they won’t eat valued specimens and your valued specimens won’t eat them) and are otherwise appropriate for your setup.
  • All members of the crew actually eat what they’re purported to eat.

#3 Ignore critter-per-gallon guidelines

Various retailers often recommend adding a certain number of snails, hermit crabs, etc. per gallon of tank capacity to keep algae in control. These types of rules are of little utility because what matters most to grazing and scavenging organisms is available real estate, not how many gallons of water the system can hold.

For example, if you have a 100-gallon aquarium that’s only sparsely aquascaped with live rockand you add 100 Astraea sp. snails to the system to control, say, an outbreak of diatoms. They’ll very quickly use up the available food supply and begin dying off.

A much better approach is to add a lower-than-recommended number of cleaner organisms to the tank and then observe their impact on the algae. You can always add more later on if necessary.

#4 Famine may follow feast

The scenario with the Astraea snails mentioned above is just one of many examples in which cleaner organisms end up eating themselves out of house and home. Another is Astropecten polycanthus, the sand-sifting starfish, which is often included in cleanup crew packages. This species does a great job of keeping an aquarium sand bed clean of detritus and uneaten food—along with any tiny organisms it happens to encounter in the sand.The trouble is, this starfish often does its job too well, consuming all the available microfauna in the sand bed and then gradually starving to death. This is often the outcome when this species is kept in small systems, it’s not provided an adequately deep sand bed, or the sand bed (regardless of its size and depth) simply doesn’t harbor an adequate population of microfauna.

#5 Crabs require caution

Various and sundry crabs, such as Clibanarius spp. hermit crabs and emerald crabs(Mithraculus sculptus), are also commonly included in cleanup-crew packages. But before adding any of these clawed critters to your system, be mindful that many of these crabs—even those that are largely considered herbivorous—are opportunistic omnivores that will sometimes decide to consume things we’d rather they didn’t.

For instance, it’s not unheard of for the ubiquitous blue-legged hermit crab (Clibanarius tricolor) to go rogue and feed on coral polyps and other small critters, including other members of the cleanup crew (i.e., snails). I can also attest from personal experience that M. sculptus is not entirely trustworthy around smaller fishes. One once sheared the entire anal fin and part of the caudal fin off a clownfish in my 75-gallon reef tank.

#6 Results will vary

As mentioned in the introduction to this post, cleanup crews can perform a very important function while providing additional interest. But keep in mind that these critter combos don’t always perform as well as advertised. Owing to factors such as the regular availability of alternate foods (e.g., fish food) in the system or the presence of excessive dissolved pollutants causing an especially intractable algae problem, these organisms may either completely ignore the items you want them to eat or make such a small dent in the problem that it’s hardly noticeable.

The bottom line is, a cleanup crew is just one part of the aquarium-maintenance picture. The rest is up to you!

10 Reasons why you shouldn’t miss out on aquarium related trade shows

Interzoo is right around the corner, and many are amped up for the event; and why not?! Whether you are a retailer, wholesaler or just generally an aquarium enthusiast attending this tradeshow gives you an opportunity to gain valuable experience & knowledge, lots of product exposure, meet suppliers, and lots more. Nothing beats the benefits that a tradeshow like Interzoo (and many other aquatic related tradeshows) has to offer in a short space of time.

 

Why Attend?

 

Trade shows serve as a very powerful marketing medium. You not only get to advertise to your target market but also create brand awareness to all significant industry players. As a visitor, you experience the entire industry specific to your interests under one roof. At one go, you can sample a wide array of products and suppliers, evaluate and compare services and products as well as get answers to questions you’d otherwise not get first hand.

 

Like in all business prospects, there will be some risk involved; such as the cost of covering your logistics for the whole event. We however think that the benefits over-weigh the risk and there can be a lot to gain from promoting your product in person within a different environment. This platform enables you to promote your product or service to a broader group that may have little or no knowledge of your products and services. You also get to branch out more in the B2B trading and grow your customer database.

 

Below is a summary of the benefits of attending a trade show.

 

  • Gain knowledge and exposure to new trends, products and resources that are available for your company. This is a great way to learn about what’s hot, what’s fading and what your company needs to have or do right now

 

  • Stimulate new ideas and creative ways to support your business despite the economy, past seasons and more. Where you will gain this knowledge is endless – your competition at the show, your general experience at the show and even your participation at the show will make an impact.

 

  • Meet other retailers and vendors who you can lean on, learn from and possibly gain business from that you would not have had the chance to meet had you not attended that trade show.

 

  • Learn what your competition is up to without having to go to great lengths since their business information will be easily accessible. Ask yourself how do you compare to your competition and evaluate your strengths and weaknesses to best support your business.

 

  • Expose yourself to the press attending the trade shows so they know about your business – retail or wholesale. Make sure your business stands out so that they will remember you.

 

  • Generate leads for strategic alliances and most importantly, potential customers. Collect business cards, refer to the directory and use all other outlets provided to you during the show to create a list of contacts for your files – and your business outreach.

 

  • Participate in educational seminars, networking events and surveys that only take place at trade shows and will expose you to new people, new business and new ways of thinking for your business success.

 

  • Get answers right away, whether from a vendor or a retailer, since trade shows allow for immediate communication and easy, accessible outlets of exposure for both vendors and retailers.

 

  • Become educated on your industry so that you can better support your clients and customers by utilizing the entire resources trade shows offer.

 

  • Have fun. Yes – have fun. Nothing gives a business owner more energy than a good time while working to keep them motivated to want to work more!(retailminded.com)

Fish Spotlight: The beautiful yet very elusive, Diamond Tail Flasher Wrasse (Paracheilinus attenuatus)

Image: reef central

The Diamond Tail Flasher wrasse, Paracheilinus attenuatus, is one of the most attractive yet lesser known species of Fairy Wrasses /Fairy Flasher from the Indian Ocean. This fish is very much sought after and why not, with all its vibrancy and stunning hypnotic colors, rendering it the most photogenic of the flasher wrasses.

The Paracheilinus genus are known as flasher wrasses because males put on an extraordinary display of exaggerated movements and intensifying “flashing” colors when courting and mating.  Aside from the display, male Diamond Flasher Wrasses look great even without being in full nuptial coloration making them great acquisition candidates for aquariums. Aquarists debate the exact number of flashers due to geographical variations and hybridization issues, but it currently stands at approximately 16 species spread out from East Africa and the Red Sea, throughout all of the Indo-Pacific, and into the western Pacific Ocean.

Diamond Tail Flashers are the only species of Paracheilinus in which the adult males sport a lanceolate or pointed caudal fin, hence the name diamond tail wrasse. The females and young males have the more common round caudal fin.

Due to the flasher wrasses desirability – they are common in the aquarium trade- we have received many requests to source for the diamond flasher. However, despite the fact that the flasher wrasses maybe common, it is unknown to some of the aquarists that some of the flasher wrasses are rarely available; the diamond tail flasher being one of them.

Why the Diamond Tail flasher is difficult to source

While we may be able to offer a few Diamond Tail Flashers to the trade, these species are few and far between. The fish which is found in East Africa, particularly our country Kenya, may only be found one or two in shipment with other wrasses after a long period of time. These fish appear in very low density and stays between 12- 25 Meters meaning that they must be decompressed so as to reach the surface, this can be very difficult for the smaller the fish.

Moreover, out in the fishing ground, it may take our diving team a whole week sourcing for the Diamond Tail Flasher without even finding 1 piece. When you consider its rarity plus the retail cost of this fish compared to the cost used up in sourcing the fish, it makes little sense as we the fish would have to go at a very expensive rate. We find it therefore difficult to do business with this fish and have previously dropped all requests to source for this fish.

Freight delays and postponement as a result of bad weather  

We would like to inform our clients’ of the disappointing start to 2018 in some parts of the world where bad weather conditions are causing delays and cancellation of shipments thereby resulting in operational challenges, inefficiencies and increased cost.

Heavy snowfall and below-freezing temperatures have highly affected our trade due to flight re-routing and cancellation of many carriers. Temperatures in affected countries are sinking below -20 degrees Celsius and forecasters predict they would continue to sink.

To our beloved clients who are affected we apologize in advance and hope that the weather conditions clear up soon. In case of a delayed or a postponed delivery, we kindly request our clients to bear with us as these are unforeseen situations beyond ours or our carrier’s control.

 

 

Fishes out of Africa by Michael J. Tuccinardi a CORAL Magazine excerpt from the May/June 2017 issue

by Michael J. Tuccinardi

Despite being the second-largest landmass on Earth, bounded by two oceans and two seas and having tens of thousands of miles of coastline, the African continent does not tend to be thought of in terms of its marine life. Africa’s east coast, however, boasts vast stretches of tropical coral reefs in the Western Indian Ocean, many of them teeming with reef fishes. And although relatively few aquarists know it, Kenya has been the site of a small-scale marine aquarium fishery supplying fishes, invertebrates, and—until recently—corals to the trade since the mid-1970s.

Kenyan marine fishes have never been a particularly common sight at American import and wholesale facilities, but in my years at Segrest Farms near Tampa, Florida, I saw a few shipments of fishes and invertebrates from East Africa come and go, piquing my interest in a region that has some truly unique species. In my own travels and explorations of the marine aquarium trade, I’ve always gravitated toward the smaller, more obscure fisheries and collecting regions, and Kenya has remained high on my list of sites to visit. When the opportunity recently arose to not only explore the coastal city of Mombasa—the country’s marine fish export hub—but also to visit collecting sites along the country’s coast with Jochen Federschmied of Kenya Marine Center (a major exporter), I enthusiastically accepted and soon found myself disembarking from a crowded flight into a hot, dusty Kenyan afternoon.

It’s no surprise that Kenya, with just 333 miles (535 km) of coastline, is far better known for its interior, which contains spectacular wildlife habitat and the famed Mount Kilimanjaro, and abuts Lake Victoria, one of the major hotbeds of freshwater cichlid diversity on the planet. Despite that, Kenya’s coast is unique in that much of it is enclosed by a massive barrier reef lying just a few miles offshore. This chain of barrier and fringing reefs extends for over 125 miles (200 km) along Kenya’s shores and southward into Tanzania. The northern Kenyan coast near Lamu has less coral cover due to the out-flowing fresh water of the Tana River, and north of that the coral reef zone is effectively bounded by an upwelling of cool water along the Somali coast, so the Kenyan and Tanzanian coasts comprise a distinct coral reef ecoregion, according to J.E.N. Veron’s online database Corals of the World (www.coralsoftheworld.org). And while the country’s reefs suffered significant bleaching during the highly destructive El Niño Seasonal Oscillation of 1999 (and in subsequent events), overall the fringing and inshore reefs have recovered and survived intact, especially in and around the nearly 10 percent of Kenya’s offshore area that has been set aside as marine protected areas (MPAs).

Kenya’s offshore habitat is diverse, including nearly every type of tropical marine ecosystem, from vast mangrove swamps, seagrass beds, and shallow Acropora– and Porites-dominated fringing reefs to extensive deepwater fields of soft corals and anemones. Over the course of my five-day visit, I was able to explore most of these habitat types and see many of the fish and invertebrate species that I had previously seen only behind glass. One of the first things that struck me about the underwater scenes off the Kenyan coast was the sheer volume of fishes present—huge shoals of Anthias were almost always in view along the reefs, and there were numerous large predatory fishes, like the schools of massive Southern Bluefin Tuna (Thunnus maccoyii) that I witnessed in the midst of a feeding frenzy just above one of the dive sites. Although it has a history of fishing and coastal resource use that extends back thousands of years, much of Kenya’s coast is sparsely populated, and there is relatively little in the way of industrial or large-scale fishing in most areas. This, coupled with the relatively healthy reefs, means that the fish assemblages along the coast have remained largely intact, despite some localized overfishing of food fish species.

The fish and invertebrate life found on Kenya’s reefs is extremely diverse, and while many of the commonly encountered species are found throughout much of the Indo-Pacific, East Africa boasts plenty of its own endemics. These unique species and distinctive populations— especially of reef fishes—have become staples of Kenya’s export trade, and over the course of my time there I was thoroughly impressed by the stunning array of fishes being collected in this undeniably exotic locale, although few are seen with any regularity in the U.S. aquarium hobby. Despite their relative scarcity in the trade, I couldn’t help but feel that many of them deserve more recognition. From an aquarium enthusiast’s standpoint, they certainly seem worth the extra effort necessary to seek them out—and not just for their uniqueness and suitability for any serious hobbyist who may have grown somewhat bored with the standard species seen in most marine and reef aquariums. I was struck by the obvious vitality and health of these fishes upon import, which was due to careful collecting methods—harmful and destructive techniques, such as cyanide fishing, are not utilized in the Kenyan aquarium trade—and short duration of transit from collection to export station.

For the next issue of CORAL I’ll examine the Kenyan marine fishery and provide a firsthand account of my time spent with the skilled divers who collect these fishes and invertebrates for their livelihoods, but for now I offer a detailed look at some of the country’s most impressive and unique fish exports, along with brief notes on their care in the aquarium.

The beautiful Blue Star Leopard Wrasse (Macropharyngodon bipartitus), a regular export from Kenya, in an exporter’s holding tank.

LABRIDAE

Blue Star Leopard Wrasse (Macropharyngodon bipartitus)
Probably the most beautifully marked of all the leopard wrasses, as members of this genus are commonly called, M. bipartitus is distributed widely throughout the Western Indian Ocean and is extremely abundant on most Kenyan reefs. Although wrasses of this genus have a somewhat deserved reputation for being delicate in the aquarium, much of this is likely due to poor handling and stress during and after collection and importation. A large, well-established aquarium, a substantial sand bed, and ample feedings of varied, high-quality foods appear to be the keys to keeping these somewhat fragile beauties thriving in captivity.

Radiant Wrasse (Halichoeres iridis)
A fish that certainly lives up to its name, the Radiant Wrasse is another Western Indian Ocean fish found in large numbers off the East African coast. Like most of its congeners, it requires a sand bed to sleep in and, while shy at first, generally adopts the gregarious behavior typical for this genus. Some reports indicate challenges with recently imported specimens, which I would probably attribute to transport stress or malnutrition. Most freshly collected fishes are active and enthusiastic eaters.

Yellowtail Tamarin Wrasse (Anampses meleagrides)
Although it is found throughout the tropical Indo-Pacific, this beautifully marked wrasse has long been considered a challenge to keep successfully. Specimens from Kenya, which do not usually suffer from extended time in transit before reaching an exporter, are likely to fare far better in the aquarium, which is why this species remains a popular export from the country.

Yellow-Breasted Wrasse (Anampses twistii)
Like other species of this delicate genus, this wrasse tends to fare poorly when handled roughly or subjected to poor conditions before and during export. Much like the leopard wrasses, they need ample sand beds and large, well-established aquariums to thrive.

Bicolor Cleaner Wrasse (Labroides bicolor)
Without a doubt an experts-only fish, this species should be kept in a large aquarium under the care of a highly experienced aquarist. Carefully collected specimens that haven’t begun wasting away due to lack of food—such as most specimens exported from Kenya—are far more likely to adapt and thrive in an aquarium.

Candycane Wrasse (Hologymnosus doliatus)
This is another commonly encountered denizen of Kenyan reefs. The attractively marked juveniles of this species tend to form loose schools as they hunt for small invertebrates. Relatively hardy in aquariums, they grow to a hefty 12+ inches (30 cm) as adults and so are only suited for large aquariums.

POMACANTHIDAE

Goldtail or Chrysurus Angel (Pomacanthus chrysurus)
This large, attractive angelfish is found only along the east coast of Africa and is among the most sought-after Kenyan exports. Although occasionally encountered on the reef, it tends to be more common in rocky and algae-dominated habitats on the North Coast.

Flameback Pygmy Angel (Centropyge acanthops)
Although remarkably similar to Centropyge aurantonotus, which, oddly enough, is found across the globe in the Southern Caribbean, C. acanthops is endemic to East Africa and sports a more vibrant orange coloration. On the reef, this fish tends to stay close to rock or coral overhangs and makes a colorful, if somewhat shy, aquarium resident.

POMACENTRIDAE

Allard’s Clownfish (Amphiprion allardi)
A beautiful, rather delicate East African species in the A. clarkii complex, A. allardi is typically found inhabiting Carpet Anemones (Stichodactyla sp.) or Ritteri Anemones (Heteractis magnifica). Although it has been bred in captivity, it is not commonly commercially available except as a wild-collected specimen from Kenya.

Vanderbilt’s Chromis (Chromis vanderbilti)
A widespread species that, unfortunately, is rarely seen in the hobby, this small-growing Chromis is both hardy and peaceful. Although not prone to forming tight schools like some of their congeners, they make attractive additions to a reef tank and tend to stick close to branching coral heads.

ACANTHURIDAE

Yellow Belly Hippo or Regal Tang (Paracanthurus hepatus)*
*distinct population
Although the Blue, Regal, Palette, or Hippo Tang is among the most well-known and immediately recognizable of all reef fishes, relatively few people are familiar with the fact that there is a distinct population of this fish known from East African waters. These fish, in contrast to the uniform blue they display throughout the rest of their range, sport a pale yellow belly that develops further as they grow. Beyond this unique color pattern, which should interest any aquarium-keeper looking for something out of the ordinary, these fish are typically collected and held under far better conditions than Indonesian specimens, so they tend to acclimate to aquarium life without the health issues that often plague this species.

SCORPAENIDAE

Gumdrop Coral Croucher (Caracanthus madagascariensis)
This bizarre and minuscule member of the scorpionfish family is extremely similar in behavior to the well-known clown gobies of the genus Gobiodon, inhabiting coral heads almost exclusively in the wild. Technically venomous, these strange little fish adapt relatively well to aquarium life and would make a fascinating centerpiece for a nano reef.

CHAETODONTIDAE

Black Pyramid or Zoster Butterfly (Hemitaurichthys zoster)
This darker, Indian Ocean cousin to the more well-known Yellow Pyramid Butterfly (H. polylepis) is found in large aggregations just offshore along most of the Kenyan coast. This species is generally considered one of the more reef-safe species of butterfly.

The smoke from a smoldering cooking fire filled the small room and lingered just above the packed-earth floor. I was in the village’s only open “restaurant,” along with a few locals, who were sitting across from me on a rough-hewn wooden bench, quietly finishing an early breakfast. The familiar sounds of early morning in the developing world drifted in through the open door and windows—a rooster crowing apathetically, the far-off drone of a motorbike, and a pack of semi-feral dogs barking just outside. The proprietor of this little restaurant—an outgoing and rail-thin man in his early 60’s—leaned over to pass me my coffee and asked what brought me out to this somewhat remote spot. When I replied “aquarium fishes,” he responded with the bemused, slightly quizzical look I’ve come to expect from that answer. “We have those here?” he asked. “In Kenya?”

The beautiful African Flameback Pygmy Angel (Centropyge acanthops) is one of the country’s best-known exports.

Many people, even longtime hobbyists, might ask the same thing. Kenya’s coastline, bordering the far western edge of the Indian Ocean, has been the site of a small but vibrant aquarium fishery for decades. Like many of the small-scale collection locales spread out across the world’s tropical oceans, Kenya’s marine aquarium fishery is relatively unknown and remains poorly studied. But the fishes that make their way into the United States and other import hubs across the world—several of which have populated my own personal aquariums—have held an enduring fascination for me, and for that reason I found myself traveling across the Indian Ocean from Colombo, Sri Lanka, to Mombasa to get a firsthand look at Kenya’s marine aquarium trade.

Arranging to see aquarium fish collectors in action, whether in the South China Sea or the Amazon Basin, is rarely a simple task. Success depends on complex, often last-minute travel plans, good weather, and no small amount of luck. On this trip, however, I had few obstacles to contend with, as I had help from one of the country’s largest fish exporters, Kenya Marine Center. The company’s founder, Jochen, had organized transportation and allowed me to accompany his divers and collectors along the coast for the duration of my visit.

And so, in the tiny village of Gazi, nestled against the mangrove forests along Kenya’s South Coast, I waited for the team of divers to meet me and begin the day. Another watery instant coffee later, they began to trickle in. One of the youngest, having had the good fortune to collect a rare Gem Tang a few days before, was clearly suffering from the after-effects of a long night of celebrating his valuable find. One of them beckoned me to the door, and I followed them out to a wide, sandy beach where the boat was waiting.

Most aquarium fish collectors in Kenya use SCUBA gear and hand nets to collect from the offshore reefs at depths of 20–60 feet (6–18 m).

FISHERY BACKGROUND: GEOGRAPHY

Over the next few days, I went out with dive teams along the coast to observe fish and invertebrate collection in action, traveling back each afternoon, along with the day’s catch, to their holding facility. Due to the relatively short coastline, most of Kenya’s aquarium trade is concentrated in a few collecting locations, most of which are only a few hours’ drive from export facilities clustered near the international airport in Mombasa.

The sprawling city of Mombasa, which has a population of over one million, is actually an island nestled into the southern edge of the Kenyan coast, less than 60 miles from the border with Tanzania. Its history stretches back over 1,000 years; it has been a Portuguese trading post, a British Protectorate, and a vassal state of the Sultanate of Oman. Today, it is a victim of the uneven pace of Africa’s urban development, and the dense population, heavy ship traffic in and around the port, and largely unregulated sprawl have heavily impacted the waters surrounding the city. Fortunately, the damage to inshore reefs has been localized, and it only takes a short time to reach intact, richly populated reefs just beyond the coast’s pristine beaches. A remarkable percentage of Kenya’s coastline is relatively healthy fringing reef, and the South Coast is home to the most vibrant of these.

This, combined with the proximity and easy road access to export facilities, is why the South Coast remains the favored region for ornamental fish collection in Kenya—and why I found myself on a traditional wooden boat heading out toward the extensive barrier reef outside Gazi, close to a kilometer from shore. The divers and boat crew, at first clearly a bit on edge having a foreigner in their midst, had relaxed and were now preparing for the dive. The majority of the collecting in Kenya is done by fairly well-organized and well-equipped dive teams using SCUBA gear. The reefs with the densest populations of desirable aquarium fishes tend to be around 30 to 60 feet (10–20 m) down, and although some areas had obviously been damaged in earlier bleaching events, these reefs were, for the most part, in good condition. The fish diversity was also remarkable; small schools of Powder Blue Tangs (Acanthurus leucosternon) were visible in every direction, and huge mixed-species groups of wrasses foraged close to the coral heads along the bottom.

NET-FISHING: AN ACQUIRED SKILL

Divers use barrier nets to collect fishes, deftly laying out the net in a semicircle on the seafloor and using it to corral the desired fishes into a smaller hand net before transferring them into standard plastic fish bags tied to their belts. Aquarium fish collecting in Kenya is, as in several other small-scale aquarium fisheries, a skilled trade requiring years of training and practice, and most of the divers I met had been collecting fishes as their primary source of income for more than five years—and some far longer. As always, I was amazed at the level of local ecological knowledge displayed by these collectors, who (when asked) can usually rattle off detailed information about the seasons for certain fishes at certain sizes, the influence of the tides and lunar cycles on fish abundance, and even what sites offer the best collecting at various times throughout the year. Each diver’s single tank of air is the major constraint on collecting, and they waste no time once in the water, scouting on their descent for groups of fishes to target and fanning out nets as soon as they reach the bottom. In a careful but hurried process, the divers spread out across the reef and pursue their targeted species, which vary according to what the exporter demands.

Although each exporter (there are three or four currently operating in the country) likely uses different methods with his own divers, the fact that Kenya’s fishes go directly from diver to exporter, typically in the same day, is hugely advantageous in terms of both communication and minimizing over-collection. Each dive team I spent time with went out with a rough list of what was needed, and for abundant or easy-to-collect fishes like damsels there was a quota in place—anything above that number would be paid for, but at a much lower price. During the 40- to 45-minute dives, the collectors gradually fill their belts with bags of fishes, from groups of Blue Star Leopard Wrasses (Macropharyngodon bipartitus) to reverse harems of the widely abundant Allard’s Clownfish (Amphiprion allardi), with the occasional larger bag reserved for single specimens of large angels like the Emperor (Pomacanthus imperator) or the sought-after Goldtail Angelfish (P. chrysurus). Above the surface, the boat crew times the dive and keeps close watch on the makeshift buoys, waiting for divers to surface.

Once the divers begin to surface, the crew springs into action and a flurry of activity ensues as the collectors, bags of freshly captured fishes in hand, haul themselves up and over the gunwales of the boat. Oxygen tanks are brought out and the divers and crew begin sorting the catch, re-bagging and changing water when necessary, before inflating the bags with pure oxygen. Each diver’s catch is placed in a separate pile in a shaded spot or under a tarp, and soon the divers begin preparing to repeat the process.

After a successful dive, collectors and boat crew work quickly to change water and fill bags of fishes with pure oxygen to ensure that they arrive at the export facility in good health.

SNORKEL COLLECTING

On a typical trip, the collectors make two dives, each lasting around 45 minutes, with a break in between while the boat makes its way to the second site. By the time the hot equatorial sun is high overhead—just around noon—the second dive has usually been completed and it is time to head back to shore. En route, the divers work quickly to re-bag most of their fishes once more, this time sorting them by size and species, performing additional water changes (big grazers like tangs and angels can make quite a mess in a short time) and, finally, marking the bags with scraps of paper on which they’ve written their initials—a simple yet effective system to ensure that each diver gets paid for the fishes he has caught.

Although teams of divers like the ones I traveled with are responsible for the lion’s share of aquarium fishes exported from Kenya, a significant percentage of snorkel-based collection occurs in the shallow inshore areas as well. On my last day in the country, I was able to accompany a group of snorkel collectors while they collected fishes and invertebrates. In contrast to the deeper coral reef habitat, this collecting site was primarily a vast seagrass flat, punctuated by rocky outcroppings with moderate coral coverage. Despite being far from “typical” reef habitat, these seagrass flats were no less productive in terms of fish diversity; dense schools of damsels, small surgeonfishes, and butterflies were easy to spot and approach. Because it requires far less skill and training, snorkel collecting is often an entry-level position for younger fishermen looking for work in the aquarium trade. Over time, snorkel collectors who prove adept at collecting and produce fishes in reliable numbers are offered the opportunity to train as divers, which comes with a substantial increase in earning potential.

After a particularly long, hot morning at sea, divers return to the export facility with their catch and unpack them before they are acclimated in holding tanks. Generally, divers are paid only for the fishes that survive the trip, so they keep a careful eye on them. It is uncommon to see any fish mortality at this stage.

Like many marine aquarium fisheries, the commercial trade in Kenya began in the early 1970s (Okemwa et al. 2005), at a time when the combination of improved air transportation and early success keeping marine aquariums drove some enterprising members of the industry to look beyond the established export points in the Philippines and Hawaii. Kenya’s reefs, which boast a wide variety of endemic, aquarium-suitable species (for more information on these, see Part I of this feature in the previous issue), made for an attractive, if logistically challenging target for the growing trade. Although there is no written history of the trade in Kenya, multiple sources relayed to me that one or more German expats began the first collection and export operation in the country. For many years, Kenyan fishes were sought by aficionados of the uncommon, but were only intermittently available. During the 1990s and into the 2000s, Kenya’s marine aquarium industry saw increased involvement by a few major importers in the US and Europe and developed significantly, and once-sporadic shipments became far more regular.

In the final stage of the process, fishes are packed for export to wholesalers and importers around the world. This packing crew is bagging Kenya’s unique “Yellow Belly” color form of the popular Blue Tang (Paracanthurus hepatus) for a shipment.

MONITORING ARTISANAL FISHERIES

For a time, even corals were exported and the main collection point, Shimoni, on the Southern Coast, became something of a well-known name among importers and members of the trade. To this day, the Kenya Tree Coral (Capnella sp.)—which, if I recall correctly, was the first coral I ever bought—remains a staple of the hobby, although its namesake country no longer allows the collection or export of any coral species. Today, a handful of exporters continue to ship fishes and invertebrates regularly from Mombasa International Airport, primarily to Europe and the United States. Although the “boom years” of the business have probably passed, aquarium fish collection remains an important business for those involved.

Like nearly all small-scale aquarium fisheries, Kenya’s has been poorly studied and would be considered data-deficient by nearly any standard. The country’s artisanal food fisheries, however, are fairly well-documented in the scientific literature, and many of its reefs have been monitored and studied for decades. This allows at least some insight into the fishery on an ecosystemlevel and, combined with what limited data does exist on aquarium fish collection, helps paint a picture of where the aquarium trade in this country, and the ecosystems that sustain it, stand today. Perhaps unsurprisingly, given the degraded state of coral reefs worldwide, this is a bit of a mixed bag. Generally speaking, Kenya’s food fish trade has remained small-scale, and they have never had a massive industrialized fishing fleet like those seen in other Indian Ocean countries. This has almost certainly helped protect reef habitat from widespread destruction due to trawling and rampant overfishing, but even small-scale fisheries can have a significant impact. Research indicates that after a peak in the late 1970s, overall catch per unit effort (CpUE, an important indicator of fishery health) has declined for all types of artisanal fishing along the coast (Samoilys et al. 2016). While this decline has not been nearly as precipitous as in some other regions, it is still indicative of trouble ahead for many of the important food fish families.

Kenya’s coral reefs, while still considered to be in relatively good health, have suffered a great deal in recent years. Major bleaching events in 1997–98 and 2007–08 caused significant loss of coral cover in many areas, although periods of recovery helped regain some of what was lost. Kenya also has an extensive range of marine protected areas along its coast, covering over 10 percent of its offshore area in total. Although enforcement of these areas (which includes strict no-take national parks) has varied in the past, a number of studies indicate strong recovery of fish and coral abundance and species diversity both in and around these areas. As is often the case, very little research has been done into the specific impacts of the ornamental trade, but given its small, localized nature and relatively low volume of locally abundant species, it is likely that the negative effects have been limited. Divers I spoke to, although keenly aware of lower numbers of food fish species in their collecting sites, generally did not see this decline extending to the aquarium species they targeted.

In an age of increasing concern about unsustainable sourcing of all manner of consumer products and widespread global decline of coral reefs, it remains surprisingly difficult to make purchasing choices for our reef aquariums that don’t contribute to either. Even defining what is and what is not sustainable with regard to the trade and hobby remains a fraught discussion, especially given the lack of research into most marine aquarium fisheries. In Kenya’s case, however, there are, at the very least, a few indicators that this fishery is among the better options for sourcing aquarium fishes and invertebrates. First and foremost, cyanide use and other destructive collecting practices are unknown in the country’s reefs. Also of great importance is the relatively direct route that freshly collected fishes take from reefs to export facilities just a few hours away. This dramatically improves survival rates and prevents the over-collection that results from poor communication between collector and buyer or the need to offset the high mortality rates associated with long, complex supply chains. Finally, Kenya’s extensive marine protected areas offer an important reservoir for species diversity and likely create what is known as the “spillover effect,” in which stocks of fishes and invertebrates in the surrounding areas are augmented. In the absence of hard data, it is difficult to support claims either for or against the sustainability of aquarium fisheries like Kenya’s, but these small-scale fisheries increasingly seem to be a better sourcing option for hobbyists looking to minimize the impact their aquariums have on wild reefs.

KEEPING FISH HAPPY: HOW WE DO IT AT KENYA MARINE CENTER

A happy fish is a healthy fish.  And keeping fish healthy is our number one priority at Kenya marine center. Are you curious to know the reason behind our high quality fish at Kenya marine center and how we have achieved that? I will share with you our secret. Having Over a decade of experience in the fish industry we have gained informative skills and strategies that have played a great role in improving our fish health.

The key thing we avoid in order to keep our fish happy is stress. A stressed fish is susceptible to diseases that jeopardize their health. At Kenya Marine center we go out of our way to ensure our fish are in a relaxed environment. We enjoy seeing our fish swimming freely and radiant in our holding facility before export.

 

Below are some tips to make your fish happy

Fish Acclimation

Acclimation is the process of accustoming the aquatic species to your aquarium water. At Kenya Marine Center we acclimate fish brought in from the wild before introducing them to our system as we prepare them for export. This process is important because fish from the wild are adapted to ocean water which has a slight difference in parameters from the one in our holding facility. Introducing fish in your aquarium water abruptly might lead to stress or PH shock. That’s why we must acclimate our fish at Kenya Marine Center.

How we acclimate our fish at KMC

Drip line Method

In this method we float the fish bag for about15 minutes in our aquarium water to equalize the water temperature. Then we pour the contents in a bucket and set up a drip line from the aquarium to the bucket. We ensure the water slowly flows into the bucket. Once the water level in the bucket is double that of actual fish bag water, we dispose half of the water without harming the fish and repeat the process. When the process is over, the fish is now ready for its new environment.

Water quality.

Water entails the whole fish environment and thus plays the main role in fish health.  Fish put in poor condition get easily stressed. At Kenya Marine Center, we avoid this by ensuring all water parameters necessary for fish are observed in the holding facility and during transportation. We test our water frequently and this keeps us alert on what’s happening in our holding facility at any given time. It enables us monitor our fish and detect any suspicious behavior or fish discomfort and hence take corrective measures with immediate effect. We ensure to keep our water safe and suitable for our fish to keep them happy and healthy

Here are the major water parameters we observe, on a daily basis.

PH: 7.6-8.4

Temperature: Optimal range 24° C to 27° C

Salinity: Specific Gravity:  Broad range 1.025

Ammonia (NH3): Zero

Nitrite (NO2): Zero

Nitrate (NO3): Ideally Zero to 25ppm

Dissolved Oxygen: >6.90 mg/L

 

Good Nutrition

Fish should be fed healthy, that you can read in every book. But what is healthy feeding? It’s ensuring your fish eat good quality food which is a must if you want them healthy. Good nutrition boosts fish immunity making them resistible to diseases. At Kenya Marine Center we are careful on selecting fish feeds as we understand that every fish has its own demands and needs, for instance, Doctor and tangs like vegetable based food while lions are predators. This strong opposition on feeding behavior force us to act on it.

We are also very careful on the amount of food we provide for our fish. We ensure to provide just enough. Feeding too much can be risky. The leftover food decomposes in water altering the water parameters hence creating an uncomfortable environment for fish which causes stress. Underfeeding on the other hand will result to emaciated fish.

Fishes who go in export are exempted from feeding for 24 – 48 HRS.

Our Biological department watch the feeding 7 days a week as it is a daily task.

 

 

 

 

Regular Treatment

A fish holding facility works different from a home aquarium and we as exporters have to react on it.

In mass animal keeping, sanitation is a very important point. Out of this reason we have to do a regular treatment program for the whole facility.

We have been practicing this over the past ten years which has played a big role in keeping our fish parasites free and healthy. Ensuring our fish are in a safe and suitable environment has increased their quality as well.

 

 

Generally, we have been kin in observing all of the above and that’s how we have managed to have the best quality fish over the ten years. Our commitment to making our fish happy and healthy has resulted to us having the most admirable and happy fish. To sum it up keeping your fish happy is ensuring they are in a comfortable environment and knowing the right way to treat them. It is important to take care of your fish if you want them to stay healthy and of good quality.

 

 

 

The right way to acclimate incoming Fish

On a biological perspective, different species have different body settings which are highly dependent on its environment. This is the reason why a certain type of species can only be found in a specific area. The same goes with marine life.

Fish cannot simply adapt and survive in a new environment. However, if you wish to migrate your fish without the risk of them dying, you need to learn the right way to acclimate incoming fish into a new ecosystem.

What is acclimation?

For you to be able to transfer fish into a new environment without compromising it, you first need to learn about acclimation. Acclimation, or acclimatization, is getting certain species accustomed to its environment.

Several factors affect the health of fish in their environment, such as the water temperature, pH level, water quality, sedimentation, and ocean conditions.

Acclimation is necessary especially if fish are to be transferred from their natural habitat to an artificial environment. This is most common when fish are taken from the lake or ocean and transferred to an aquarium.

Naturally, fish are not easily affected by environmental changes when they are in their natural habitat and can always opt to migrate once a sudden disruption occurs. An artificial environment cannot originally meet the fish’s physical needs and need to be supplied with chemicals and adjust its oxidation level which can stress the fish and cause them to have illnesses and die.

Different types of acclimation methods

Entering your fish into a new environment abruptly can cause stress and illness. The right way to acclimate incoming fish comes in several methods. As simple as they may sound, several factors are also considered for these to be done properly.

Floating method

  • One way to acclimate incoming fish is through the floating bag method. The right way to acclimate incoming fish with his method is by allowing the bag the fish comes in with to float in the aquarium water. In its first fifteen minutes, the bag should be floated with its lid closed.
  • Open the bag afterward and roll the lid outwards to allow oxygen to come in and disperse the carbon dioxide accumulated.
  • Gradually put a small amount of aquarium water in the bag and continue to do so every five minutes. Once the fish bag is full of aquarium water, you need to scoop the fish out of the bag and transfer him/her/them to the aquarium. The idea of this method is to gradually adjust the fish’s body to the temperature of the water. At first the bag is floated with the lid closed to slowly adjust the bag’s temperature to the aquarium water.
  • Take note that you shouldn’t spill the water from the bag when transferring the fish already to the aquarium as this may disrupt the pH level of the mixed waters in the bag with the aquarium.

This method is best used for fresh water fish as they are less sensitive to pH level changes. Out of the two acclimatization methods, this is the easiest one with no other apparatus needed and can be done at home.

Drip method

 

If floating method is suited for freshwater fish, drip method is the only acclimatization method for saltwater fish. This method is more tedious and would require a five-gallon bucket and two air tubes and gang valves.

  • The right way to acclimate incoming fish through the drip method is by allowing the fish bag to float in the aquarium water with closed lids for the first fifteen minutes and opening the lid afterward. Gradually transfer small amounts of aquarium water as well in the fish bag every five minutes as well.
  • After conducting the first three steps of the floating method, transfer the fish to the bucket by spilling it together with the water in the bag. Make sure that the fish will not be exposed to the air during the transfer and must be completely submerged in water once in the bucket.
  • Attach one end of the air tube to the siphon drip line of the aquarium and place one end of the tube to the bucket. You can regulate the drip flow by using an airline control valve or simply tying knots on the tube.
  • Turn on the siphon drip, with four to five drips going to the bucket per second. Once the amount of water doubles, throw half of its volume and continue dripping until the water reaches the same level.
  • Afterward, scoop the fish into the bag, close the lid, submerge it in the aquarium, and finally open the bag to free the fish to their new environment.

The entire process takes a minimum of one hour. In this method, patience is really needed and monitoring is necessary.

Acclimate the fish the right way from one water to another

Acclimating fish is a tedious process. Simple as these methods may sound, the actual demonstration would require patience and careful handling of the fish. Several factors are considered when transferring them to a new environment, mainly the water temperature and the water quality.

Another factor to be considered when acclimating is light. During the acclimatization process, keep the lights off for at least four hours as this also affects the temperature and the entire adjustment process of the fish to its new environment.

Transferring fish to another habitat could bring them stress and cause illnesses and even death, the reason why the right way to acclimate incoming fish is given. Allow the fish to stay in their new habitat for at least week to fully adjust.
