| Summary: | In the New Zealand EEZ, most fish stocks are managed using TAC limits. Much of the scientific advice for the management of these stocks and associated species was derived from analyses using generic or standardised software packages and modelling techniques. These modelling techniques have also been applied to several Antarctic fish populations through various CCAMLR working groups, including the setting for TAC of toothfish fishery. CASAL is an age- (or size-) structured fish stock assessment model. Developed about ten years ago, it was mostly used in NZ EEZ stock assessments and in CCAMLR toothfish stock assessments. SeaBird is a population modelling package developed to undertake assessments of sea birds and help evaluate the impact of fisheries-related mortality on sea bird populations. The Spatial Population Model (SPM) is a spatially explicit integrated statistical catch-at-age stock assessment model that is similar in functionality aspects to CASAL. Implemented as a generalised package, it ... |
