Haplochromis simpsoni

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Haplochromis simpsoni faces severe pressure from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines across endemic cichlid species. Overfishing and the use of destructive fishing methods have further reduced remaining populations. Water quality degradation from agricultural runoff and urban pollution has altered the lake's ecosystem, affecting breeding success and juvenile survival rates.

Threat summary

Habitat

This endemic cichlid inhabits the shallow rocky shores and sandy bottoms of Lake Victoria, typically found at depths of 2-15 meters. The species prefers areas with moderate vegetation cover and rocky substrates that provide shelter and breeding sites.

Haplochromis simpsoni is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Haplochromis simpsoni faces severe pressure from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines across endemic cichlid species. Overfishing and the use of destructive fishing methods have further reduced remaining populations. Water quality degradation from agricultural runoff and urban pollution has altered the lake's ecosystem, affecting breeding success and juvenile survival rates.
Where does Haplochromis simpsoni live?
Haplochromis simpsoni occurs in Uganda. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Haplochromis simpsoni?
The main threats to Haplochromis simpsoni are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
