| dc.description.abstract | At the request of the working group, two replacement yield (RY) estimates have been produced, using the area-disaggregated modelling framework. These RY estimates are the commercial TAC which can be taken each year in the future to ensure the total male biomass remains at current levels, i.e. that T Bm (16/06) = 1.0. In addition commercial RY estimates, it is assumed 320 MT will be taken recreationally, and that 500 MT will be taken by poaching. The two RY estimates differ with respect to the assumptions regarding the future somatic growth rate. The first RY is calculated assuming the full range of integrated values of somatic growth – that is a relative ratio of 50:40:10 of low, medium and high future somatic growth rate scenarios to eventuate. The second RY assumes that only the low somatic growth scenario will occur in the future. | en_ZA |
