Recorded at 50 meters.
Habitat: reef-associated. Catface rockcod. Attains 80 cm. Known only from southern Mozambique to Knysna. Common to depths of 50 metres. Inhabits reefs and rocky bottom to a depth of at least 50 m; juveniles are found in tidepools. Feeds on fishes, spiny lobsters, and crabs. Sexual maturity is attained at 50 to 60 cm. This species falls under the category of "Collapsed stocks" -- Those species whose adult (spawning ) populations stand at less than 25% of historical levels.

The species has a very restricted range, although there is no indication that extent of occurrence or area of occupancy are declining. The reported range is from 24°50'S to 34°05'S (Heemstra and Randall 1993). The species does not occur in water depths much greater than 50 m, and, based on calculated sea floor area to the 50 m isobath, the extent of occurrence of the species is therefore about 15,400 km². The area of occupancy is in reality much less than this, since the species is closely reef-associated, and assuming that 10% of the area of occurrence is reef, then effective habitat (reef) area is about 1,500 km². Not all of this reef area is in fact suitable habitat, since a large proportion of this is coral reef and E. andersoni is not a coral reef species.
This species is classified as Near Threatened as current data indicate a population reduction of ≥30% is possible due to fishing over a 10 year or three generation period where the time period includes both the past and the future i.e., just misses listing as VU A2d+3d+4d – current population trend is unknown but an increase in fishing pressure and the limited range mean that attention is needed for this species. Although the EOO and AOO are small, especially for a marine species with pelagic larvae, there is no evidence of declines, fluctuations or fragmentation in these areas. It also occurs in relatively shallow, and therefore accessible, waters.
Relevance to Humans and Ecosystems
The brown-spotted rockcod or catface rockcod (Epinephelus andersoni) is a species of fish in the Serranidae family. It is found in Mozambique and South Africa. Its natural habitats are shallow seas, coral reefs, and estuarine waters.
