| 中文摘要: |
| 1982年碧流河水库建成后，其库内洄游型香鱼形成陆封型种群。现有的捕捞数据表明，1999年以来，碧流河水库香鱼资源量锐减，该种群极有可能在碧流河水库内消失。对碧流河水库陆封型香鱼消亡的原因进行了分析，并就恢复措施进行了探讨。认为陆封型香鱼栖息环境恶化、自身不利变异、敌害鱼类和竞争鱼类抑制作用以及人为活动的破坏导致了碧流河水库陆封型香鱼的消亡；针对上述问题，积极有效的措施是通过实施人工增殖放流、控制敌害鱼类和竞争鱼类数量加强对香鱼资源的恢复和保护。 |
| 英文摘要: |
| Migratory Ayu, Plecoglossus altiveli, has been restricted to the Biliuhe reservior and formed a landlocked population since the clorure of the dam in 1982. According to the current data, the production of the fish sharply has decreased since 1999. The population of the stock is very likely to disappear in the reservior. This paper discussed the reasons for decline of Plecoglossus altiveli in Biliuhe reservior and explored its restoration methods. The reasons for decline includes environmental degradation, the disadvantage variation, the stress of predator fish and competitive fish and human＇s activity . In response to these issues, some measures should be carried out, and these measures include making artificial release, controlling quantity of predator fish and competitive fish, and protecting the environment and landlocked ayu resource. |
