Why is the sea salinity high in the Mediterannean and Red Sea and low in Indonesia and Malaysia? [66] By 1938, Wisconsin's commercial fishing operations were motorized and mechanized, generating jobs for more than 2,000 workers, and hauling 14million pounds per year. Periodic mass die-offs result in vast numbers of the fish washing up on shore; estimates by various governments have placed the percentage of Lake Michigan's biomass which was made up of alewives in the early 1960s as high as 90%. The lakes have not benefited from this development, however, and have been seriously affected by pollution. During World War II, the risk of submarine attacks against coastal training facilities motivated the United States Navy to operate two aircraft carriers on the Great Lakes, USSSable and USSWolverine.
