Sex-change rules, stock dynamics, and the performance of spawning-per-recruit measures in protogynous stocks... Although each sex-change rule leads to the prediction that the stock will be sensitive to the size-selective fishing pattern and may crash if too many reproductive size classes are fished, the performance of traditional spawning-per-recruit measures, the fishing pattern that leads to the greatest yield, and the effect of mating group size all differ distinctly for the four sex-change rules...
Micro-analytical models – relative yield per recruit- winter school on towards ecosystem based management of marine fisheries – building mass balance trophic and simulation models... A model that describesthe state of the stock and yield when the fishing pattern has been the same over a longperiod so that all recruited fish alive are exposed to fishing is termed as a steady statemodel
