Pacific bluefin tuna (Thunnus orientalis) has been designated an endangered species, and there are international restrictions on catching this fish. Fixed net fishing in Hokkaido, however, has been taking large hauls of juvenile Pacific bluefin tuna (under 30 kg). As a result, Hokkaido has already substantially exceeded its total allowable catch for the one-year period starting July 2017. If the situation continues unchecked, there is a risk that Japan will exceed its national quota. The Fisheries Agency is calling on fishermen to limit their catch. Japan exceeded its national cap last year. As the world’s largest consumer of tuna, Japan will not be able to escape the charge of irresponsibly fishing Pacific bluefin tuna.


Hokkaido was allocated a catch limit of 57 tons for the year. As of Oct. 20, however, over 600 tons has already been caught, more than ten times the cap. According to the prefecture’s fisheries management section, the limit was exceeded in just one week, so it asked fishermen’s cooperatives to refrain from catching tuna and to release any tuna unintetionally caught.  (Abridged)
