CatDyn: Fishery Stock Assessment by Generalized Depletion Models

Using high-frequency or medium-frequency catch in biomass or numbers, fishing nominal effort, and mean body weight by time step, from one or two fishing fleets, estimate stock abundance, natural mortality rate, and fishing operational parameters. It includes methods for data organization, plotting standard exploratory and analytical plots, predictions, for 237 types of models of increasing complexity, and six likelihood models.
