Collapse of linefish stocks between cape hangklip and Walker bay, South Africa
The state of the linefishery between Cape Hangklip and Walker Bay on the Cape south coast, South Africa, is assessed. The coast was subdivided into 20 “beats” to provide high spatial resolution on catch and effort of theshore-based recreational fishery. An observer recorded the number of anglers in...

The state of the linefishery between Cape Hangklip and Walker Bay on the Cape south coast, South Africa, is assessed. The coast was subdivided into 20 “beats” to provide high spatial resolution on catch and effort of theshore-based recreational fishery.

Catch-and-effort data for the commercial boat-based fishery were obtained from an historical database at the turn of last century and from the extant National Marine Linefish System database. Catch per unit effort (cpue) of shore-anglers was low and many of the species caught earlier in the century have disappeared from catches.
