Abstract or Summary
  • This paper provides a Total Allowable Catch (TAC) assessment model for a single gear, multi-species fishery in South Korea. To estimate appropriate Allowable Biological Catch (ABC) of mackerel and jack mackerel caught by the large purse seine fleet in the territorial waters of South Korea, the model uses an extended Beverton-Holt yield per recruit model and a biomass-based cohort analysis. The extended Beverton-Holt yield per recruit model adds two terms [a relative bycatch index (wi) and a relative instantaneous fishing mortality index (ai)] to the original Beverton-Holt model [1]. The reason for adding new terms is because bycatch of those species caught by the large purse seine can affect the instantaneous fishing mortality and the recruitment of each species. In conclusion, this paper suggests that the current ABC level of mackerel needs to be lowered to prevent overfishing of jack mackerel with the small stock due to bycatch.
