A preliminary stock assessment in SSRUS 486A, G: A Bayesian and CPUE based biomass dynamic model
implemented in each species of toothfish. Tagging data was not used in any of the toothfish models, because of ... the low number of recovered individuals and low tag size-overlap. Modelling abundance in both species ... contribution to estimate abundance in a simple biomass dynamic model for both species of toothfish in northern ... sets in which both species are present, and thus, an analysis of catch intention was implemented by ...
