Lethrinus macracanthus suffered a massive decline in population on initiation of the trawl fishery in the south of Lake Malawi in the early 1970's. It immediately declined to the level of local extirpation from the southern part of the lake. The species is very rarely encountered in other parts of the Lake and it is estimated that the total population includes less than 2,500 mature individuals of which each sub-population is unlikely to contain more than 250 individuals. This information is derived from the Malawi fisheries department research trawling records since 1970. The species is assessed as Endangered.

Habitat and Ecology [top]

Habitat and Ecology:Occurs in habitats with sandy bottoms in waters of 35–65 m deep. Feeds on invertebrates as well as diatoms. In the 1970s this species was reported to have declined in demersal trawl catches but by the early 1990s it was observed that it may have become locally extinct in the south eastern arm south of Boadzulu Island due to over exploitation. Reported not to have been exported in the aquarium trade (1990). Max. size: 23 cm TL.
