Scientists at Oceanic Institute have announced a breakthrough that could be good news for both the aquarium industry and for Hawaii\u2019s coral reefs.<\/p>\n

Oceanic Institute has been making \u2018significant breakthroughs\u2019 in rearing and feeding technology for the yellow tang (\u2018Zebrasoma flavescens\u2019), which could impact both the aquarium trade and reef protection measures in the future. Photo from Oceanic Institute.<\/p><\/div>\n

Principal researcher Chatham Callan said that since 2001 they have devel- oped breeding techniques that improve prospects for raising the eggs of the sought-after yellow tang via aquaculture settings. And more recently, Callan and his team in OI\u2019s finfish department have found a way to boost Zebrasoma flavescens\u2019 survival rate past a critical growth period.<\/p>\n

\u201cWe\u2019ve developed rearing methods for both the larvae and their prey enabling them to eat and survive through the critical first- feeding stage, which up until now, has not been achieved,\u201d he explained. The findings are published in Global Aquaculture Advocate\u2019s Jan.-Feb. 2013 edition.<\/p>\n<\/div>\n

According to Callan, more than 300,000 of the vivid yellow, arrow-shaped tang are collected in the wild and exported from Hawaii each year for the aquarium trade. If they can be bred successfully in house, that helps conserve the reefs. \u201cWe\u2019ve improved radi- cally, not only in total eggs, but also quality of eggs,\u201d Callan said. The article reports that OI has gone from producing no viable eggs to a monthly yield of 1 million, a mean fertility rate of 84 percent and an egg viability rate of 51 percent.<\/p>\n

Other team members working on yellow tang culture technology are Charles Laidley (Waikiki Aquarium), and OI colleagues Eric Martinson of Aina Haina, Michael Dean Kline and Melissa Rietfors.<\/p>\n
