The changes in oxygenation are considered consistent with measurements of higher algal biomass and productivity. [44][83] To boost fishing, several species of non-native tilapia and Nile perch were introduced to the lake in the 1950s.

This may seem like a long time, but in geology, it is considered a fairly young lake. There are many beach resorts on the islands around Lake Victoria. [41] This is far more species of fish than any other lake in the world, except Lake Malawi.

Because of this, most of Lake Victoria's nutrients are thought to be locked up in lake-bottom deposits. The increasing amounts of algae, in turn, increase the amount of detritus (dead plant material) that falls to the deeper portions of the lake before decomposing.
