Abstract：As fisheries conservation and management turning common and regulated,researchers are fo-cusing on bycatch studies and management.Blue shark(Prionace glauca)is a pelagic highly migrated species,which is also a significant bycatch species in tuna longline fishery.Catch data of North Pacific blue shark(P.glauca)from International Scientific Committee for Tuna and Tuna-like Species in the North Pacific(ISC)was used and a suitable operating model was built to represent fisheries and stock dynamics.MSEtool was used in R to quantitate management procedures and make trade-offs to select the best management procedures.Abundance index data of Japan,Hawaii,Mexico and the Pacific Community(SPC)were fitted to the model to provide total allowable catch(TAC)recommendations.Then sensitivity analysis was conducted to test robustness of the model.Our results will provide China scientific support and technical security in attending global fisheries management campaigns.
