The growing commercial fishing industry is concentrated mainly in Lake Malawi, with small-scale activity in Lake Malombe, Lake Chilwa, and the Shire River. Fish farming is carried on in the south. The total catch in 2000 was estimated at 45,000 tons. Large employers of labor in the Southern Region are the major buyers, and much of the catch is sold directly to them. Fish from Lake Niassa contribute about 70% of animal protein consumption.
