Algal physical chemical characteristics of Lake Nabissojjo and their relationship to the fisheries production

Abstract

Algae are microscopic plants in aquatic environments and include the Dlue green (Cyanophyles), Green (Chlorophytes), Diatoms (Bacillariophyles), Dinophytes Chrysophytes.Several or these may be absent or present due to environmental limitations existing in a specific water body. Algae are primary producers in aquatic systems and are a major component of the aquatic food web. They are also an important SOurce of the food for major fishes such as Tilapia. Changes in algal species composition and abundance may affect the fishery. Changes in Ihe environment,especially nutrient concentrations and physical parameters,can also calise changes in algal species composition and abundance. Nutrients play a big role in all aqualic systcms as Ihey are among thc basic requiremenl for algal production processes. However excess of these nutrients can be a nuisance in the system. Changes in Ihese parameters may affect the fisheries production
