Haplochromis petronius

Unknown

Overview

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

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

Threat summary

Habitat

This cichlid species is endemic to Lake Victoria, inhabiting rocky shores and sandy-bottom areas in the littoral zone. It typically occurs at depths of 2-15 meters where it feeds on invertebrates and algae among the substrate.
