Eutrophication of central European lakes has wiped out a significant proportion of the endemic fish fauna , so climate-induced further eutrophication is expected to represent an additional threat to fish fauna and commercial fisheries . Given that the ecological consequences of lake warming may be especially strong in the Tropics , ecosystem services may be most affected there. Tropical lakes support important fisheries  that provide a critical source of nutrition to adjacent human populations. These lakes are especially prone to the loss of deep-water oxygen due to warming, with adverse consequences for the productivity of fisheries and for biodiversity  .
