Abstract

An assessment of the South African monkfish resource was initially undertaken by Booth (2004) and comprised a simple replacement yield model given that the application of a modified version of hybrid agestructured surplus production models failed to converge due to the uninformative nature of the data. Furthermore, the data for the West and South Coasts were modeled separately. The analysis was updated by Glazer (2008) and a further update given additional data is presented in this paper. Indications are that replacement yields of around 6900 tons on the West Coast and 1400 tons on the South Coast would maintain biomasses at current levels.
