Projections for the South African hake resource for the 2010 reference set of operating models under a constant catch equal to the current TAC [PDF]
This paper reports performance statistics and plots for projections of the South African hake resource under the twelve operating models comprising the agreed Reference Set (RS) (Rademeyer and Butterworth, 2010a) and using the projection methodology set ...

An initial attempt at a spatially structured stock assessment for the South African hake resource [PDF]
This document presents a first attempt at a spatially structured model for the South African hake (the model equations are set out in Appendix 1). It is currently assumed that M. paradoxus and M.

GLM-based standarization of the catch per unit effort series for South African west coast hake, focusing on adjustments for targeting other species [PDF]
Catch per unit effort (cpue) data for the South African west coast Cape hakes Merluccius capensis and M. paradoxus were standardized by applying the Generalized Linear Modelling (GLM) technique.

Two possible variants suggested at the last DWG meeting to the Base Case hake CMP structure are examined. The results obtained suggest no need to modify this baseline structure. This document reports the results of the consequent investigation, which was conducted based on the CMPf1a tuning (a median average catch over 2011-2020 of 137 000t, and a 5 ...

An initial attempt at a spatially structured stock assessment for the South African hake resource, including explicit movement [PDF]
The distribution area for the South African hake population is separated into nine regions to accommodate an initial attempt at a model of the dynamics which reflects explicit movement of the two species of hake both longshore and offshore. Commercial

Characterisation of the dietary relationships of two sympatric hake species, Merluccius capensis and M. paradoxus, in the northern Benguela region using fatty acid profiles [PDF]
The two sympatric species of Cape hake, Merluccius capensis and M. paradoxus, have been the main targets of bottom-trawl fisheries off Namibia for several decades.
