Artificially cultured bluefin tuna hatched in Japan

Researchers at Japan's Fisheries Laboratory of Kinki University have succeeded in artificially hatching 860,000 fertilized eggs from 120 adult tuna that were artificially hatched in 2002. The second generation of tuna fry has grown to a length of about 5 cm. Dr H Kumai, head of the laboratory, claimed that Japan had produced the world's first complete lifecycle of bluefin through artificial aquaculture methods, creating an incentive to strengthen the tuna production business in the near future.
