The introduced species fishery of Lake Naivasha, Kenya: ecological impact vs socio-economic benefits
Publikováno v:
Fisheries Management and Ecology. 22:326-336
Lake Naivasha is a shallow, freshwater lake in the eastern Rift Valley of Kenya. Its fish community now comprises only introduced species. Oreochromis spirulus niger was stocked in 1925 as a forage fish for the largemouth bass, Micropterus salmoides,

The increasing frequency of extreme flow events as a consequence of climate change could potentially impact the stability of lowland clay streams in East Anglia. Some of these rivers act as conveyors of additional water that is pumped downstream to s

Following the accidental introduction of the carp Cyprinus carpio into Lake Naivasha during 1999, a sustainable population became rapidly established and in early 2004 became the principal species exploited in the commercial fishery. Over 9000 kg of

Over a 9-year period (1993–2001), the land-water width of a papyrus fringe on the southern shore of Lake Naivasha, Kenya, varied between 40 and 60 m. Increases in width via rhizome spreading into open water followed the 1997/1998 El Nino flood when
