The catch from the sea and from freshwater aquaculture includes mackerel, anchovy, tuna, mullet, rainbow trout, squid, kelp, sea urchin eggs, pollack eggs, and shrimp. The FAO estimated production for 2000 was 200,850 tons. About 90% of fishing activity is marine, concentrated in the Sea of Japan / East Sea. Much of the annual catch is now used for export.
The fishing industry is entirely socialized, with some 230 maritime cooperatives and more than 30 state-run fishery stations. The main fishing ports are on the east coast.
