The decrease in fishery productivity in Lake Tanganyika since the 1950s is a consequence of global warming rather than just overfishing, according to a new report from an international team of researchers. The team found that during the 1800s, the lake became warmer at the same time the abundance of fish began to decline.
However, large-scale commercial fishing did not begin on Lake Tanganyika until the 1950s. The researchers say the new findings help illuminate why the lake’s fisheries are foundering.Image credit: Saskia Marijnissen, UNDP
