In the long-run, cage farming may create new environmental challenges. First, both the Nile perch upsurge in Lake Victoria and the increase of eutrophication occurred between the late 1960s and early 1980s. Cage farmers in Kenya – where most of Lake Victoria's cage activity is based – currently produce about 40,000 tons of fish per year. Inhabits channels, lakes and irrigation canals.Adults inhabit deep water, while juvenile shallow water.Feeds on fish especially clupeids and.

Guidelines by the East African Community for cage farming already exist , but these must be enforced and other regulations developed. In our research , we argue that cage aquaculture or farming, where fish are raised and harvested in a netted enclosure in an existing water system, could provide an alternative to how fish are produced.
