註釋

A number of reference points are suggested in the context of 3Ps cod. These are computed for the final SPA model accepted in the most recent assessment of this stock. F(loss) and spawner biomass corresponding to 50% asymptotic recruitment are suggested as initial limit reference points. At current stock size there is a low risk of falling on the wrong side of these limit reference points in both short and medium term risk analyses for a status quo TAC of 30,000 t. However, there is a high risk of remaining below B(msy) and a significant risk of exceeding F(msy) for the status quo TAC in both short and medium term risk analyses.
