these lakes is underscored by the richness in fish and invertebrate species, many of
which are endemic.
However, many of the watersheds around Lake Victoria and other lakes are
highly populated, and conflicts among user groups have increased the demands on
the lakes’ resources. Consequently, collapses of fish stocks have been observed in
most of the lakes due to overfishing. Introductions of exotic fish species such as
the Nile perch (Lates niloticus), though followed by increases in fishing pressure,
have been accompanied by a severe decline and in some cases extinction of native
fish species.
