Gene-edited sea bream set for sale in Japan

JapanNutrition.com -- Sep 23

A startup that has edited the genes of red sea bream so that they produce a thicker fillet has announced plans to start selling the fish in Japan.

The Kyoto-based Regional Fish Institute partnered with Kyoto University and Kindai University to develop a "Madai" red sea bream with 20 percent more meat by using a gene-editing tool such as CRISPR to knock out a protein that suppresses muscle growth.

According to NHK World-Japan, the startup has now notified the health ministry of its plan to market the fish and began taking orders for trial sales last week.

While genetically modified food that contains foreign genes must undergo safety screening in Japan, gene-edited products don’t face the same rules, as was reflected by the sale of tomatoes containing a nutrient thought to lower blood pressure that went on sale online in the country this week.
