Modelling crustacean fisheries: effects of parasites on management strategies
. To manage a parasitized stock, we suggest that strategies should vary depending on the recruitment ... dynamics of both host and parasite. For a certain spatial scale, recruitment to a population may be " ... protection of females on a hypothetical fishery for different combinations of host and parasite recruitment ... dynamics. The models suggest that the common practice of releasing females is not advantageous when a ...
