Haplochromis granti

Declining

Overview

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

Haplochromis granti faces severe threats from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines through predation and competition. Eutrophication from agricultural runoff and sewage has degraded water quality and reduced oxygen levels in the lake's deeper waters where this species historically occurred. Overfishing and destructive fishing practices have further reduced population numbers and disrupted the lake's ecological balance.

Threat summary

Habitat

Haplochromis granti is endemic to Lake Victoria in East Africa, where it inhabits rocky shores and deeper waters of the lake. This cichlid species was historically found in areas with rocky substrates and clear waters before the lake's ecosystem underwent dramatic changes.

Why is Haplochromis granti classified as Critically Endangered?
Haplochromis granti is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Haplochromis granti faces severe threats from the introduction of Nile perch (Lates niloticus) into Lake Victoria, which has caused dramatic population declines through predation and competition. Eutrophication from agricultural runoff and sewage has degraded water quality and reduced oxygen levels in the lake's deeper waters where this species historically occurred. Overfishing and destructive fishing practices have further reduced population numbers and disrupted the lake's ecological balance.
Where does Haplochromis granti live?
Haplochromis granti occurs in Kenya, Tanzania, and Uganda. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
