Haplochromis katavi

Unknown

Overview

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

Haplochromis katavi faces severe pressure from introduced Nile perch (Lates niloticus) in Lake Tanganyika, which predates heavily on native cichlid species and competes for resources. Overfishing using fine-mesh nets has significantly reduced population numbers, while water quality degradation from agricultural runoff and sedimentation threatens the species' specialized rocky habitat requirements. The species' restricted range within specific areas of Lake Tanganyika makes it particularly vulnerable to localized environmental changes.

Threat summary

Habitat

Haplochromis katavi inhabits the rocky shores and shallow waters of Lake Tanganyika, typically found at depths of 5-15 meters among boulder fields and rocky substrates. The species shows strong site fidelity to specific rocky areas where it feeds on algae and small invertebrates.
