Importance:

The Ocean sunfish is described as one of the heaviest bony fish in the world, with a sister species recorded as the heaviest bony fish. It forms part of the large iconic sunfish group seen by many water users. Furthermore, the species forms part of the mid-water trawling bycatch. Knowledge of this specific species is important for sustainable fisheries management and understanding the phylogeny in South African waters.
