According to Kinki University, the thickened red sea bream destroyed the gene that suppresses the growth of muscle cells at the fertilized egg stage by genome editing.As it grows, it has a maximum of 1.6 times more muscle mass and an average of 1.2 times more muscle mass than ordinary red sea bream, and the edible part has increased significantly.

　In order to realize it by conventional breeding, it is necessary to repeat mating and breeding for generations, but genome editing will be realized in a few years.Since the gene was not introduced from the outside, the safety was considered to be equivalent to breeding, and it was judged by the expert meeting of the Ministry of Health, Labor and Welfare that there was no problem.

　The name is "22nd century sea bream".It is cultivated in an aquarium on land to separate it from the natural world.We plan to send 190 servings of kelp-tightened and sardine to the people who provided funding through crowdfunding from October, but for the time being, we will not sell them to the general public and will hurry to mass-produce them.

　Regional Fish started in 2019 with Assistant Professor Masato Kinoshita of the Graduate School of Agriculture, Kyoto University and Professor Keitaro Iedo of the Fisheries Research Institute of Kinki University as founders.Japan's fishery industry is steadily declining, with landings of 1988 million tons in 1,278 dropping to 2018 million tons in 442, and aquaculture utilizing genome editing technology is likely to attract attention.
