Although this means greater potential supplies, it also means greater potential pollution, degradation of the aquatic environment, and upsetting of the balance in local environmental and social systems.

It provided dramatic evidence of the limited size of fishery stocks, evidence already substantiated by biological investigations. 0 percent a year. Recently there has been a reported increase in production, much of which has come from aquaculture and from small, shoaling pelagic species (of relatively low value). There have also been large increases in certain small pelagics, notably the Japanese sardine and other Pacific sardine stocks.
