摘  要:
本文首次报道驼背大麻哈鱼人工放流及其回归效果。根据驼背大麻哈鱼具回归母河川的生物学特异性,在注入日本海的绥芬河水系进行移植放流试验。1988年4月放流稚鱼72万尾,1989年6~8月放流群体回归母河川,在我国境内河区重捕回归成鱼 647尾,比该水系自然群体猛增约30倍,回归率为0.087%,标志回归率为0.023%。该项放流试验效果显著,为绥芬河水系驼背大麻哈鱼资源增殖提供重要的科学依据。

摘  要:
Based on the migrating feature of salmon and testing on the trans-plantation of the species to Suifen River, smolt releasing and adults returning ofpink salmon have been made. In October 1987, 930000 eyed eggs were importedfrom Sakhalin Russia. After artificial incubation and rearing, 790000 smolt(38mmin length, 0.37g in weight) were released into the Suifen River. Among the relea-sed smolt, 30000 individuals were marked by fin-clip. From June to August, 1989,647 returning fish (457mm in length, 1220g in weight) were captured-recaptured.The returning population was 10 times much higher than before. The returningrate of the released fish was 0.087% and the returning rate of the marked fish was 0.023%(uncounted the lower section inside of Russia). As the test achieved remar-kable success,the releasing amount should be further increased and the cooperationof Sino-Russia on the enhancement of the salmon resources should be streng-thened.
