A total of 13 lobster stocks were subjected to a c.ohort analysis by length, and the effects of size limit and fishing mortality changes on yield per recruit assessed. In the main the data analyses indicated the advantages and necessity of increased minimum size limits and for decreased fishing mortality. As well as increasing Y/R such management action would ensure considerable increases in stock biomass, and therefore recruitment potential, which would reduce the severe risk of imminent fishery induced recruitment failure. Furthermore, the Group recommended that immediate attention must be given to the modelling of lobster growth, with special reference to the effect this has on yield assessment models.
