摘要

历史上,大比目鱼渔业一直是加拿大太平洋沿岸渔业的重要组成部分。洄游大比目鱼种群在1923年生效的联合管理制度下与美国共享。过去,加拿大的捕捞量有很大一部分是从美国海岸附近的水域捕捞的。在实行200海里的限制后,加拿大船只被禁止进入美国的区域。与此同时,自然条件的变化导致大比目鱼种群规模的减少。结果,加拿大大比目鱼船队只能满足于捕获量的大大减少。但是,合理管理渔业的条件由于同美国达成了一项新的联合管理协定而有所改善,保证加拿大在两国的总捕获量中享有固定的公式份额。本文讨论了加拿大重组其大比目鱼渔业的可行方案,以减少规模,但提高回报率。

Rationalization of Canada's Pacific halibut fishery

The halibut fishery, historically, has been an important sector of Canada's Pacific coast fishing industry. The migratory halibut stocks have been shared with the United States under a joint management regime, in effect since 1923. In the past a large share of the Canadian catch was taken from waters off the American coast. After imposition of the 200-mile limit Canadian vessels were barred from the American zone. At the same time, changes in natural conditions led to a reduction in the halibut stock size. As a result the Canadian halibut fleet must content itself with a greatly reduced catch. However, conditions for rational management of the fishery have improved as a result of a new joint management agreement with the United States, guaranteeing Canada a fixed formula share of the aggregate catch of the two countries. The paper discusses the options available to Canada to restructure its halibut fishery on a reduced scale, but with better rates of return.
