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. The data set was extend to 1972 and a new tuning survey is used, the Canadian survey during 1978-1985. As there are inconsistencies with total catch o...
