Captive raised yellow tangs have finally happened. Researchers at the Oceanic Institute, led by Dr. Chan Callan, successfully broke through a bottleneck in raising yellow tang fry. The first captive raised tangs were on display in Florida for the first time ever and in this Fincast John shows you the beautiful fish as they graze on real live rock for the first time, while Callan himself describes the process his team went through to finally find the formula to keep the young alive through he delicate larval stage.

John here with another Fincast. History is being made at the Global Pet Expo because of of fish that’s on display that’s never been on display before. In a certain sense never existed before and that is an aquacultured yellow tang … a yellow tang born and raised in captivity. Researchers have been working for more than a decade to get it done and the man who did it is here and will talk to him in this Fincast.
Chad Callan: Well after 10 years or more of research we have basically succeeded in culturing in the yellow tang for the first time. And some of those fish are on display over here. And the reason this is such a big deal first time is because it’s the first time I surgeonfish species has been cultured. It was largely thought to be impossible.
Dr. Chad Callan has reason to be proud, standing in the Boyd Enterprises booth at the Global Pet Expo in Orlando, where, along with the nearby display by Segrest Farms the acquacultured yellow tangs raised by his team at the Oceanic Institute in Hawaii were on public display for the first time.
Callan: We’re really excited that we were finally able to do it and we were able to get significant numbers of juveniles and actually get those out to the industry.
Dave Parks/Segrest Farms: We received the fish about a week ago were really really excited. One of the best parts is that the industry put that much trust into Segrest Farms. To actually receive really what is the Holy Grail of Marine Fish. So we’re really really excited we think it is a true privilege to receive the fish from the first batch.
Jeff Turner/Boyd Enterprises: Every time I see something related to aquaculture in this trade easy to get excited. It’s really easy to get excited about it and think what can we do next to help support that.
Carlin: Callan showed me the fish in the aquarium, which were grazing on live rock. Amazing – since they had never seen anything but the plastic pipes in their rearing tank in Hawaii.
Callan: These guys seem quite happy to be coexisting and there and they are interacting with the other fish to which is nice. They haven’t seen any other species species they only links lived among their own kind so they’re getting used to other friends and that’s kind of cool to see you too.
Carlin: I asked him how he finally did it – how did he get the fish beyond the size of about a nickel where they always died.
Callan: There was no real one breakthrough. It’s really been an incremental process of trial and error with the larvae. Probably the biggest probably the biggest difference is that occurred was the feeding regime for the larval fish where we overlapped a variety of different feeds for the larvae, and that allow them more choice of what they wanted to eat at any one time through and gave us the ability to finally get them through. But difficult period.
Callan: with video over/ So the video that you’re seeing is first of those first juveniles basically schooling together in their new PVC pipe reef.
Carlin: Callan’s team at the Oceanic Institute, with increasing collaboration from Rising Tide Conservation, has now raised three batches of yellow tangs. Almost all of them distributed to public aquariums from Segrest Farms in Florida and west coast wholesaler Quality Marine. Up next he says, will be several more attempts, and a scientific journal, before hopefully commercial breeders pick up the baton and begin growing the tangs in numbers that will support the hobby.
Callan: So basically what we’ve what we’ve been able to demonstrate is that this is actually feasible. This actually is a realistic possibility these fish can be available to the industry as cultured, but what we need to do is develop a method further so that is really commercially feasible. … And so I think what the industry wants to see that demonstration in and what would we looking for is industry support.
Carlin: Which he’s already getting from Quality Marine and Segrest Farms, which are donating money from initial sales back to the project, and from Boyd Enterprises, which brought Callan to the show.
Dave Parks: When it comes to something like this you know, here at Segrest … we really didn’t have the knowledge and know-how to actually reproduce and grow the fish initially. And we need to return it and we need to return that investment to the people who can actually do that successfully.
Jeff Turner: To move this along and help support it which were doing financially in and of course with bringing out this to the public it’s really a great. We will give Chad several thousand dollars for the Oceanic Institute dedicated for this research. I hope that many other industry players will come up with some money to put into it as well.
Callan: Like I said, it almost doesn’t seem real. It’s taken so long to get to this point that you kind of just our speechless (laughs)
So there it is, look at what several people have called the holy Grail of Apple cultured fish it’s been done three times now in captivity and the important thing is they know how to do it now they have to ramp up production before four they’ll be available in the store where you could buy an iPod culture tank. But this is a great step forward and I can tell you some other people from talking with some other people at the same process is very close to working with the hippo tang or the Dori tang as it’s better known known and of course with the Disney movie coming out there be a lot of people talking about that. So graduation congratulations to Chad Callan n at the oceanic Institute in Hawaii and what an opportunity interview him it was to interview him and to be here and see these fish at global. Thanks for watching and I’ll see you in the next Fincast.
