Assessment of the Cod Stock in NAFO Division 3M
An assessment of the cod stock in NAFO Division 3M is performed. A Bayesian model, as used in the last assessments, was used to perform the analysis. Results indicate a fairly substantial increase in SSB, reaching a value well above Blim. The six-years retrospective plot shows that the recruitment i...
