Lake Tanganyika Fish Quantity Declines Due To Rising Temperatures

Lake Tanganyika, the second largest freshwater lake in the world, is responsible for providing several neighboring African countries their dietary resources. Over the past few decades, the lake has seen a decline in fish, which has long been credited to overfishing. But new research implicates a different culprit: rising temperatures.

Researchers gathered samples of sediment from the bottom of the lake and conducted a chemical analysis of the fossils found. The team discovered a correlation between rising temperatures and falling fish numbers.
