太平洋鳕鱼（Merluccius productus）和相应的生产产量的生物变化被用来模拟从收获到加工的垂直综合渔业。季节性生物经济规划模型将存量动态与内在鱼质量、收获时间表和异质用户群体之间的配额分配的交互经济效应相结合。最佳的管理计划将最大限度地贴现净产业收入（NPV）给定最低产卵生物量。当季节内收获时间与鱼类质量的季节性改善相吻合时，NPV最大化（例如，在产卵和/或迁移之后）。但是，净现值只受到各组之间配额分配的轻微影响。版权所有1999年，牛津大学出版社。
Biological changes in Pacific whiting (Merluccius productus) and corresponding production yields were used to model a vertically integrated fishery from harvest through processing. The seasonal bioeconomic programming model incorporated stock dynamics with the interactive economic effects of intrinsic fish quality, the harvest schedule, and quota allocation between heterogeneous user groups. The optimal management plan would maximize discounted net industry revenues (NPV) given a minimum spawning biomass. NPV was maximized when the intraseason timing of harvest coincided with the seasonal improvement in fish quality (e.g., following spawning and/or migration). NPV was only marginally affected, however, by the quota allocation between groups. Copyright 1999, Oxford University Press.
