Effects of resources and mortality on the growth and reproduction of Nile perch in Lake Victoria

Changes in Nile perch population size-structure and stocks make the threat of collapse imminent, and the outlook for Lake Victoria stocks is bleak, according to a new report by the United Nations Environment Programme.

Differential decline and recovery of haplochromine trophic groups in the Mwanza Gulf of Lake Victoria

The patterns of decline and recovery indicate that, though fishery played a role locally, predation by Nile perch and eutrophication were the main factors determining the fate of the haplochromines.

Species Distinction and the Biodiversity Crisis in Lake Victoria

By studying cichlid communities, trophic groups, and individual species, researchers uncovered differential diversity in gross morphology and the presence of intraspecific variation that made it difficult to distinguish among species.

Seven new species of detritivorous and phytoplanktivorous haplochromines from Lake Victoria

Seven new species of haplochromine cichlids from Lake Victoria are described. They comprise four detritivorous and three phytoplanktivorous species. Their affinities to other Lake Victoria

Lost zooplanktivorous cichlid from Lake Victoria reappears with a new trade

The authors' observations provide a new example of the extreme versatility in feeding behaviour in haplochromine cichlids, as it had been suggested that, because of anatomical constraints, molluscivory and zooplanktivory are incompatible in cICHlid fish.

Monitoring the invasion of the aquatic bug Trichocorixa verticalis verticalis (Hemiptera: Corixidae) in the wetlands of Doñana National Park (SW Spain)

The presence of the North American native corixid Trichocorixa verticalis verticalis (Fieber, 1851) in Doñana wetlands (SW Spain) is detected and two reproductive populations that might act as sources for the colonization of other waterbodies in the area are found.

Cichlid species diversity in naturally and anthropogenically turbid habitats of Lake Victoria, East Africa

Clear water seems to support differentiation in feeding techniques as well as year-round spawning, and both may facilitate species coexistence, which may explain why, since the decline of Nile perch, haplochromine densities have recovered, the numbers of hybrids increased and species diversity in the current eutrophic sub-littoral waters has remained 70 % lower than before the environmental changes.

Biological diversity of the Yala Swamp lakes, with special emphasis on fish species composition, in relation to changes in the Lake Victoria Basin (Kenya): threats and conservation measures

The biodiversity of the swamp and the three lakes is discussed and suggestions for their conservation are given.

Spatial and seasonal patterns in the feeding habits of juvenile Lates niloticus (L.), in the Mwanza Gulf of Lake Victoria

Stomach content analysis showed that with increase in size, the diet of Nile perch shifted from zooplankton and midge larvae, to macro-invertebrates (shrimps and dragonfly nymphs) and fish, and the contribution of prey types appeared to be habitat related.

The destruction of an endemic species flock: quantitative data on the decline of the haplochromine cichlids of Lake Victoria

The species composition of haplochromines in a research area in the Mwanza Gulf of Lake Victoria prior to the Nile perch upsurge is described, which would imply that approximately 200 of the 300+ endemic haplochromaine species have already disappeared, or are threatened with extinction.

THE NILE PERCH IN LAKE VICTORIA: INTERACTIONS BETWEEN PREDATION AND FISHERIES

A bioenergetics model of Nile perch predation rates was used to evaluate the consequences of previous, current, and future fishery exploitation patterns and their ecological implica- tions and produced three main conclusions.

Initial Results of the Ecological Survey of the Haplochromine Cichlid Fishes From the Mwanza Gulf of Lake Victoria (Tanzania): Breeding Patterns, Trophic and Species Distribution

Breeding of the bulk of the haplochromine species (phytoplankton/detritus eaters, zooplanktophages and some insectivores) in the sublittoral and littoral waters with a mud bottom appears to be seasonal, and an optimal trawl fishery recommendations based on the present data are discussed.

Hypoxic wetland tributaries as faunal refugia from an introduced predator

Wetland conditions seem to limit exploitation by Nile perch providing critical refugia for a subset of the basin fauna, but chronically low oxygen conditions in the werland tributary may permit persistence of only hypoxia-tolerant species.

An analysis of species changes in Lake Victoria: did the Nile perch act alone?

Catches of traditional species have further decreased and the fishery now largely comprises three species: the total demersal exotics, Nile perch and Nile tilapia and a native zooplanktivorous, pelagic cyprinid, Rastrineobola argentea, the dagaa or omena (Chapters 2–11).

Cichlid Fish Diversity Threatened by Eutrophication That Curbs Sexual Selection

Cichlid fish species of Lake Victoria can interbreed without loss of fertility but are sexually isolated by mate choice, and human activities that increase turbidity destroy both the mechanism of diversification and that which maintains diversity.

During the years 1984–1987 Lake Victoria in East Africa experienced what is probably the largest mass extinction of contemporary vertebrates. Within a decade about 200 endemic species of
