Habitat and Ecology [top]
Habitat and Ecology:
This deep sea species can be found at depths of 170-1,060 m, but is most commonly found between 500-750 m. This species inhabits soft muddy substrates, and can reach a maximum body length of 15 cm, although most commonly specimens are around 10 cm in size (Holthuis 1991).
Systems: Marine
Use and Trade [top]
Use and Trade:
This species is harvested commercially at a small scale in South Africa, but it is unknown if it is harvested in any other area of its range. Since 1997, three deep water trawling vessels have been permitted to fish for crustaceans, including this species, off KwaZulu-Natal, South Africa (Booth and Hecht 2000). This species is caught as by-catch in a trawl-fishery for Palinurus delagoae based in Durban, South Africa (Groeneveld 2000). However, there is no catch data available for either of these areas. Small catches were recorded during exploratory trawling off Madagascar (1/2 kg per hour or less) (Holthuis 1991).
