Eggs on tuna farm

摘要

"And on that farm he had a..." tuna? Aquatic Old MacDonalds have moved a stride closer to fully farming bluefin tuna now that all three species of the fish - one of the most endangered of those caught for commerce - have bred in captivity. Umami Sustainable Seafood of San Diego, California, announced last week that some of its captive northern bluefin tuna have spawned. The next step is to demonstrate that the larvae can grow into fully mature fish, completing the entire life cycle in captivity.
