White Stumpnose

(Rhabdosargus globiceps)

Wit stompneus, Vyfvinger

This species is under revision for linefishing

1. What is it?

White stumpnose (Rhabdosargus globiceps) are relatively fast growing, long-lived, endemic fish making them moderately susceptible to overfishing. They are considered over fished across most of their range and are listed on IUCN’s Red List for Threatened Species as Vulnerable.

2. How was it caught or farmed?


White stumpnose are caught using traditional linefish methods rod and reel or handline. The linefishing industry often operates from small ski- and deck. Linefishing is a relatively selective fishing method with few impacts on the marine environment and little accidental bycatch.

Inshore demersal trawl

White Stumpnose are caught as bycatch in the inshore trawl fishery, which targets sole and hake (hake catches are MSC certified). The fishery gear consists of trawl nets that are dragged along the seabed at different depths up to the 110 m isobath or to 20 nautical miles from the coast, whichever is the greater distance. Demersal trawling is known to damage the seabed; the extent and impact of this damage remains unknown. Trawling is not a selective fishing method and a number of other species are often caught in the nets (fish, sharks and rays). Substantial effort has been made to reduce seabird deaths through the use of tori lines and research is underway to better manage the principal bycatch stocks through a co-management pilot programme.

3. Where is it from?


White stumpnose are endemic to the coastal region of the Kei River to southern Angola. . Management for the sector is considered partly effective. In South Africa this sector is principally managed through a total allowable effort (TAE) limitation and there are additional restrictions to protect overfished species such as bag (10 pp/day) and minimum size (25 cm) limits for recreational fishers. There is some concern over the impact of the small-scale fishery rights allocation beyond the recommended TAE and the continuously growing recreational sector.

Inshore demersal trawl

White stumpnose are caught between Cape Agulhas and the Great Kei River at depth shallower that 110 m. Management is considered to be largely effective. Management is mainly directed at the target species hake (MSC certified) and sole in the form of Total Allowable Catch (TAC) and permit limitations. A fishery conservation project (FCP) was developed to test a co-management approach for 10 non-target species in the sector. Other concerns include the lack of information on impacts to sensitive shark, skates and ray populations as well as impacts to the seabed. Efforts are underway to improve the scientific observer coverage at sea for this sector to better understand ecosystem impacts.
