Bycatch Control in Multispecies Fisheries: A Quasi‐rent Share Approach to the Bering Sea/Aleutian Islands Midwater Trawl Pollock Fishery
利用1991-1992年白令海鳕鱼渔业的船队数据,通过估计多物种生产技术的准租金函数,推导出最优兼捕规则和配额价格,为渔业管理提供依据。
Abstract “Optimal” bycatch rules and quota share price estimates are derived from a multispecies production technology model of the factory trawler fleet targeting on midwater pollock in the Bering Sea/Aleutian Islands region of the North Pacific Ocean. Data routinely collected by federal and state fisheries officials on catch and revenue by species, week, and operation are used to identify the aggregate restricted quasi‐rent function for the fishery by estimating the associated system of inverse demands for species quotas. The model is estimated using data for the 1991 and 1992 seasons, and separability and nonjointness of the technology are tested for and rejected.
