资源简介：
An age-structured production model (ASPM) is developed for the rock lobster populations at each of the four islands of the Tristan da Cunha group (Tristan, Inaccessible, Nightingale and Gough Islands).The ASPM model is sex-disaggregated as there are substantial differences in growth rates and hence lengths at age between the sexes.The model is fit to GLM- or GLMM-standardised longline CPUE and catch-at-length data. A catch series for each island is used. Although commercial harvesting first began in 1949, the ASPM models are run from 1990 because of considerable uncertainties regarding pre-1990 catches and related problems encountered with model-fitting when the models are initiated in 1949.
