摘要利用渔业机构的数据库和文件，我们汇编了一个关于不列颠哥伦比亚省和育空溪流的淡水马哈鱼种群(Oncorhynchus属)状况的摘要数据库。然后，我们通过在不列颠哥伦比亚省各地的渔业专业人士和利益集团中分发数据库来收集补充信息，从而确定了9662条滨河鲑鱼种群。这些种群包括866条Chinook，1,625条，2,594条Coho，2,169条粉鱼，917条红鱼，867条钢鱼和612条远洋鲑鱼。我们通过采用与Nehlsen等人相似的分类方案来评估滨水种群的状况。(1991年)。所有股票中有5,487只(57%)可以进行评估，包括所有具有商业重要性的大型股票。评估发现，本世纪有624只股票处于高风险，78只股票处于中等风险，230只股票受到特别关注，142只股票被剔除。由于缺乏可靠的数据，我们无法对4,172只(43%)的股票进行分类。由于他们的SMA。
Abstract Using fisheries agency databases and files, we assembled a summary database on the status of anadromous salmon stocks (genus Oncorhynchus) from British Columbia and Yukon streams. We then collected supplementary information by circulating the database among fisheries professionals and interest groups throughout British Columbia and thus identified 9,662 anadromous salmon stocks. These stocks included 866 chinook, 1,625 chum, 2,594 coho, 2,169 pink, 917 sockeye, 867 steelhead and 612 sea-run cutthroat trout stocks. We assessed the status of anadromous stocks by employing a classification scheme similar to that of Nehlsen et al. (1991). Assessments were possible for 5,487 (57%) of all stocks and included all large, commercially important stocks. The assessments found 624 stocks were at high risk, 78 were at moderate risk, 230 were of special concern, and 142 were extirpated in this century. We were unable to classify 4,172 (43%) of the stocks because of an absence of reliable data. Due to their sma...
