✦ Synopsis

The limnological characteristics of Lake Kariba are briefly described . Any change in the physico-chemical nature of the lake waters naturally implies that the environment for fish is also changed . Dispersal of fish species according to conditions existing in the five basins of the lake is dictated by the marked graduation from fluviatile to partly lacustrine, to lacustrine conditions, when passing from Basin 1 through to Basin 5 .

The fish in Kariba are of Middle Zambezi River stock and as a consequence those showing strong ties with the riverine habitat, particularly in relation to spawning requirements, have orientated towards affluent rivers, or areas influenced by rivers .

The Cichlids have adapted to the lacustrine conditions . Evidence of these trends in distribution have been extrapolated from commercial landings.

## Abstract The population density of __Orconectes limosus__ in a mesotrophic lake was assessed in the context of fish and macroinvertebrate biomasses, and crayfish consumption by fish. The average __O.__ __limosus__ (β‰₯6 cm total length) abundance and biomass in the littoral zone was 2200 ind ha^–1
