2. A simple approach for calculating the potential yield of krill from biomass survey results

   Abstract:  Estimates are calculated for the parameter λ in the yield equation Y = λ M B0 for a ... kri11 fishery in which both the fishery and kri11 growth are seasonal. The criterion used for the ... calculations is that the probability that the kri11 spawning biomass drops below 20% of its average pre ... -exploitation level over a 20 year period of harvesting should not exceed l0%.
