The Economics of Salmon Ranching
研究了鲑鱼放牧作为商业活动的经济问题,分析了其生物基础、全球发展模式及华盛顿州私营盈利模式与公共渔业的共存策略。
The emergence of ocean ranching as a commercial venture has raised a variety of new and intriguing questions which confront all those policymakers who must shape that industry's future growth. The broadest definition of ocean ranching would include all public and private salmon culture operations, which together sustain 20-30% of world salmon production (Thorpe 1980), primarily through contributions to sport and commercial capture fisheries. This analysis, however, focuses on the currently small private sector of the ocean ranching industry in which the primary economic objective is the harvest of returning adults by hatchery operators. Section 1 describes some of the biological characteristics of salmon and cites developments in salmon culture which provide the economic rationale for ocean ranching. Section 11 notes the various ways in which ocean ranching has developed around the world. Finally section III analyzes in more detail one approach advocated in Washington State and elsewhere-development of a private profit-oriented ocean ranching industry alongside a significant sport and commercial capture fishery.
