Lake Tanganyika Fisheries Declining From Global Warming

[font size=4]The new finding shows that overfishing is not the sole reason for the decline in the lake's fisheries, says study leader Andrew Cohen, a UA geoscientist.[/font]

[font size=3]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 led by a University of Arizona geoscientist.
The lake was becoming warmer at the same time in the 1800s the abundance of fish began declining, the team found. The lake’s algae–fish food–also started decreasing at that time.
However, large-scale commercial fishing did not begin on Lake Tanganyika until the 1950s.
…
"Some people say the problem for the Lake Tanganyika fishery is 'too many fishing boats,' but our work shows the decline in fish has been going on since the 19th century," Cohen said. "We can see this decline in the numbers of fossil fish going down in parallel with the rise in water temperature."
