Fishing in the North Sea
From Wikipedia, the free encyclopedia
Fishing in the North Sea is concentrated in the southern part of the coastal waters. The main method of fishing is trawling.[citation needed]
Annual catches grew each year until the 1980s, when a high point of more than 3 million metric tons (3.3 million S/T) was reached. Since then, the numbers have fallen back to around 2.3 million tons (2.5 million S/T) annually with considerable differences between years. Besides the fish caught, it is estimated that 150,000 metric tons (165,000 S/T) of unmarketable by-catch are caught and around 85,000 metric tons (94,000 S/T) of dead and injured invertebrates.[1]
Of the caught fish, about half are used for the production of fish oil and fish meal.[citation needed]
