Assessment of the Cod Stock in NAFO Division 3M

An assessment of the cod stock in NAFO Division 3M was conducted using a Bayesian SCAA (statistical catch-at-age) model. The STACFIS catch estimates and the Flemish Cap survey indices were used to fit the model. Blim, defined as the SSB of 2007, was estimated at 15 037 t (median). Results indicate a...
