中文摘要:
      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。
英文摘要:
      Based on the migrating feature of salmon and testing on the traas-plantation of the species to Suifen River, smolt releasing and adults returning of pink salnaan have been made. In October 1987,930000 eyed eggs were imported from Sakhalin Russia. After artificial incubation and rearing,790000 smalt(38mm in length, 0.378 in weight) were released into the Su.ifen River. Among the relea-sed smolt, 3}UOD individuals were marked by fin-clip. From .Tune 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 returning rate 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 cooperation of Sino-Russia on the enhancement of the salmon resources should be streng-thened.
