The krill yield model uses a biased estimate of SB0 with a method for correcting this bias in the ... of SB0 in the krill yield model compared to the unbiased estimate in the generalised yield model. The ... results show that the biased estimate of SB0 results in a biased estimate of the probability of critical ... bias in the krill yield model will result in the catch level, γ, given for a set probability of ...
