Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Trematocranus microstoma faces severe pressure from overfishing in Lake Malawi, where intensive commercial and artisanal fishing operations have dramatically reduced cichlid populations. The species is particularly vulnerable to gill net fishing methods that target the rocky shoreline habitats where it feeds and breeds. Water quality degradation from agricultural runoff and sedimentation has altered the lake's ecosystem, affecting the algae and small invertebrates this specialized feeder depends upon.
Habitat
Trematocranus microstoma inhabits the rocky shoreline areas of Lake Malawi, typically found at depths of 5-20 meters where it feeds on algae and small invertebrates among the rocky substrates. The species prefers areas with clear water and abundant rock formations that provide both feeding opportunities and shelter.
