Stratification, Mixing and Transport Processes in Lake Kivu,fluences the top ∼65 m. Below, the lake is permanently stratified, with density increasing stepwise from ∼998 kg m. at the surface to ∼1,002 kg m. at the maximum depth of 485 m. The permanently stratified deep water is divided into two distinctly different zones by a main gradient layer. This gradie

Phytoplankton of Lake Kivu,kton is dominated by cyanobacteria – mainly . spp. and thin filaments of . – and by pennate diatoms, among which . and . are dominant. Seasonal shifts occur, with cyanobacteria developing more in the rainy season, and the diatoms in the dry season. Other groups present are cryptophytes, chrysophytes

Fishes in Lake Kivu: Diversity and Fisheries,oduced Tanganyika sardine, .. Lake Kivu is famous, compared to the other African great lakes, for its poor fish fauna, with 29 species comprising a.o. 15 endemic haplochromines and a few non-native species. In a first part devoted to diversity and biogeography, all species are briefly described, wit
