Intrinsic fish characteristics and intraseason production efficiency: A management-level bioeconomic analysts of a commercial fishery

Biological changes in Pacific whiting (Merluccius productus) and correspond ing production yields were used to model a Vertically integrated fishery fr om harvest through processing. The seasonal bioeconomic programming model i ncorporated stock dynamics with the interactive economic effects of intrins ic fish quality, the harvest schedule, and quota allocation between heterog eneous user groups. The optimal management plan would maximize discounted n et industry revenues (NPV) given a minimum spawning biomass. NPV was maximi zed when the intraseason timing of harvest coincided with the seasonal impr ovement in fish quality (e.g., following spawning and/or migration). NPV wa s only marginally affected, however, by the quota allocation between soups.
