Japan's CRISPR Fish Enters Market

January 12, 2022

Two CRISPR-edited fishes were approved for sale in Japan. The country now has three approved CRISPR-edited foods to date.

The two fishes were developed by the Regional Fish Institute in collaboration with Kyoto University and Kindai University. The CRISPR-edited tiger puffer had its leptin receptor gene disrupted, resulting in the fish's increased appetite and rapid gain in weight. On the other hand, the CRISPR-edited sea bream had its myostatin protein disabled. This causes the fish to grow larger than the conventional sea bream using the same amount of feed. The traits are expected to reduce the farm production cost of the fishes.
