Human-induced changes in the composition of fish communities in the African Great Lakes

Establishment of introduced species: main species introduced; factors affecting establishment; physical factors; competition; predation; reproduction; food and feeding. Effects of introductions on the fish community: clupeid introductions; introduction of Nile perch. Effects of fishing on the fish community: Lake Victoria; Lake Malawi; Lake Tanganyika; Lake Kariba. Conservation of unique faunas. Mitigating measures for fish species conservation: captive propagation; reduction of Nile perch stocks; closure of haplochromine fishing; creation of conservation areas.
