Ocean Institute’s Captive-Bred Yellow Tangs

 Congratulations to the team at Ocean Institute for their success with the world’s first captive bred yellow tang; this is truly a remarkable feat!  In their own words: “They are a little camera shy, but here’s some video of our recently settled Yellow Tang!! If you look closely you’ll see some that are still in the process of turning yellow. Stay tuned for more information on this incredible achievement! For now, just enjoy the yellow! Thanks to all the crew (Dean Kline, Emma Forbes, Aurora Burgess, Erin Pereira, Randall Scarborough, Renee Tousse & Blake Thompson) for making this a reality!!” video credit: Blake Thompson… More:

Fully captive bred Yellow tangs to go to market?

Yellow tang public domain squareMany aquarists and hobbyists alike look forward to the day when aquaculture farms are teeming with millions of colourful fish to help stock public aquariums rather than wild caught individuals fitting the bill.  The reason it’s not happening now with all the species, according to some who have tried rearing the elusive Yellow Tang, is that resources are limited and getting the juveniles past the 90 day mark is quite a feat. “Getting good survival of the larvae is the main problem, especially that first week,” said Syd Kraul, owner of Pacific Planktonics.  Kraul is currently raising flame angelfish, multicolor angelfish and yellow tang at the Natural Energy Laboratory of Hawaii Authority.   He reckons that the tang, in particular, is in high demand and very difficult to raise.  “Out of 10,000 eggs, you might get 200 to 300 larvae that survive the first week,” he said. “That’s not enough. By 90 days you won’t have any left.”  The 90-day point is when the fish change from clear to yellow and take up shelter in the rocks. Kraul has been raising aquarium fish since 2006 and now he thinks he finally has it figured out and hopes to offer yellow tang on a commercial basis within a year. “It’s no secret. It’s just about getting the right balance of food in the water,” he said. “Put in too much food and the fish are going to die. They need the food but they need clear water. That’s the challenge.” Oceanic Institute and Pacific Aquaculture and Coastal Resource Center are two other facilities trying their hand at culturing aquarium fish so who knows, perhaps there’ll be a race to get the first fully captive-bred Yellow Tangs to market.  Keep your eyes peeled! For more information, go to:… More:

Oceanic Institute Taking Baby Steps Toward Culture of Yellow Tang

Fisheries researchers at the Oceanic Institute in Hawaii have been working—not so successfully—for years to develop culture techniques for the commercially and ecologically important yellow tang (Zebrasoma flavescens). In an attempt to step back a bit and work with a decidedly less difficult subject, they recently brought in clownfish broodstock. The idea, explains Research Scientist Chad Callan, Ph. D., is that they can in due course use information gained from success with the easily cultured clownfish to successfully culture yellow tangs. The delicate marine ecosystems of Hawaii are increasingly under threat from overfishing as well as the indirect consequences of urban development. Marine conservation officials estimate that approximately 500,000 to 800,000 yellow tang are taken from Hawaiian waters each year. As this figure accounts only for reported cases, the actual total harvest may be considerably higher. The animal lives as long as 30 years in the wild; however, it takes many years to reach sexual maturity. Callan believes that having a sizable, ongoing aquaculture program for the species would contribute enormously to conservation efforts; not only would cultured yellow tangs help to meet demand in the ornamental fish trade, but they could also be used to restock depleted areas in the wild.… More: is the world's leading destination for sustainable coral reef farming and the aquarium hobby.
