Bias in the estimation of krill yield from using a deterministic formulation of the median unexploited spawning biomass
fishing season and spawning season will result in less bias occurring. Author(s): de la Mare, W.K ... ). 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 ...
