What kills fish in lake Victoria?

Answer 1

Fish in Lake Victoria are primarily threatened by a combination of factors including pollution, overfishing, and the introduction of invasive species, particularly the Nile perch. Eutrophication caused by agricultural runoff leads to harmful algal blooms, which deplete oxygen levels in the water, further stressing fish populations. Additionally, habitat destruction and climate change contribute to the declining health of the lake's ecosystem. These factors together create a challenging environment for native fish species to survive.
