Abstract:
The XSA model traditionally used by AFWG for the North-East cod stock assessment is to be considered as only one of great variety of age-structured stock assessment models used for this purpose in the present world, and the model which is not without known important shortcomings. Our results obtained using the TISVPA model, the model aimed at robustness and with attention to generation-dependent peculiarities, may indicate that the XSA-derived results may lead to erroneous perception of the stock and hardly can be regarded as the only and sufficiently reliable basis for further management decisions.
