Japanese Bluefin Tuna Aquaculture - Tuna Farming and Harvesting - Tuna Processing Factory

Prized for its high fat content, bluefin tuna are perhaps the most prized fish in the ocean. In the modern sushi industry closed-cycle aquaculture may be the key to the species future on menus. In Japan, Kindai University began exploring this possibility in the 1970s by collecting eggs from captive adult fish and artificially inseminating them. They then waited for the eggs to hatch into larvae that they could raise to maturity. Once the larvae became adults and laid eggs, the process would be repeated to produce full-cycle farmed fish.
