The challenges of modelling and assessing fisheries resources

ICES Journal of Marine Science, 2023
Abstract Many years after the publication of Beverton and Holt’s on the Dynamics of Exploited Fish Populations in 1957, many of the problems that they highlighted remain unsolved. For example, accurately estimating critical biological and fishing processes such as growth, natural mortality, recruitment, and selectivity continues to be ...
