摘要 孵化场的使用一直是西北太平洋地区鲑鱼和鳟鱼资源管理中长期争论的话题。这一问题的部分原因是孵化场鱼类的广泛分布，而自然种群因涉及孵化场鱼类的管理政策而处于不利地位，而且管理效果与人工繁殖效果相混淆。最近，争议集中体现在向渔业管理机构提出的建议中，即不应允许过量的孵化鱼在野外产卵，并且孵化鱼应被排除在《濒危物种法》所列的鲑鱼种群之外。本文的作者不同意这些建议，并得出结论，孵化场鱼类在恢复和补充野生种群方面发挥着重要作用。本文试图通过提供有关孵化场鱼类和相关文献的不同视角来帮助平衡讨论。
Abstract The use of hatcheries has been a subject of lengthy debate in the management of salmon and trout resources in the Pacific Northwest. The problem has resulted in part from the wide distribution of hatchery fish in circumstances where natural populations were disadvantaged by management policy involving hatchery fish and the confusion of the effects of management with the effects of artificial propagation. Recently, the controversy has been epitomized by the recommendations to fisheries management agencies that excess hatchery fish should not be allowed to spawn in the wild, and hatchery fish should be excluded from salmon populations listed under the Endangered Species Act. The authors of the present article disagree with those recommendations and conclude that hatchery fish have an important role in recovery and supplementation of wild stocks. The present article is an attempt to help give balance to the discussion by providing a different perspective on hatchery fish and the literature pertainin...
