Bias in the estimation of krill yield from using a deterministic formulation of the median unexploited spawning biomass
correction. This paper examines the implications for estimates of krill yield from using the biased estimate ... , while the second is a generalised yield model. The decision rules relate to the effects of a specified ... long-term annual yield (γ) on (i) the probability of the spawning stock being reduced below a set ... proportion of SB0 during a projection run (probability of critical depletion) and (ii) the median status of ...
