Abstract Recently it was claimed that an increase in regional temperature, related to global climate change, has resulted in substantial decline in the pelagic fish catches from Lake Tanganyika, East Africa. Surface temperatures of Tanganyika indeed show warming trends, but evidence for decreased productivity is ambiguous, and no overall decline in fish catches has been documented. In contrast, total lake-wide fish catches increased up to 1995, increased artisanal catches outweighing regional declines in industrial fisheries. We conclude that the present evidence is not sufficient to demonstrate the effects of climate change on fish stocks in Tanganyika. Evidence indicates rather that fishery intensification has been the major factor affecting fish populations.
