Abstract

The baseline two mixing stock assessment of South African sardine has been conditioned on parasite prevalence data on the south coast east of 22◦E only (Dunn et al. 2015, de Moor and Butterworth 2016). Data between 20 and 22◦E were excluded from the baseline assessment to ensure no age-1 sardine from the west stock that were not permanently moving to the south stock were included in south stock prevalence data. This document explores the sensitivity of the assessment results to including the parasite prevalence data between 20 and 22◦E.
