  "Description": "Based on fishery Catch Dynamics instead of fish Population\nDynamics (hence CatDyn) and using high-frequency or\nmedium-frequency catch in biomass or numbers, fishing nominal\neffort, and mean fish body weight by time step, from one or two\nfishing fleets, estimate stock abundance, natural mortality\nrate, and fishing operational parameters. It includes methods\nfor data organization, plotting standard exploratory and\nanalytical plots, predictions, for 100 types of models of\nincreasing complexity, and 72 likelihood models for the data.",
