本文报道在注入黄海的大洋河水系进行大麻哈鱼类移殖放流试验。利用大麻哈鱼类回归母河川的生物学特性，采取移殖放流方法．１９８５—１９９３年从日本移殖大麻哈鱼、驼背大麻哈鱼、马苏大麻哈鱼、银大麻哈鱼发眼卵共６８３．９万粒，向大洋河放流稚鱼５１０．７万尾；在１９８７—１９９２年收集到回归大洋河的大麻哈鱼、马苏大麻哈鱼成鱼２３尾。试验结果表明黄海北部水域具有大麻哈鱼类栖息、洄游的生态条件和大洋河开展增殖放流的可行性。
In this paper, we report the experiment of releasing and releasing salmon in the Dayang River system injected into the Yellow Sea. Taking advantage of the biological characteristics of the salmon returning to the mother river, the method of relocating and releasing was adopted. Between 1985 and 1993, a total of 6.839 million kernel eggs were produced from Japanese salmon, humpback salmon, salmon mahogany and silver salmon, and 5,107,000 juveniles from Dayanghe. In 1987-1992, a large collection of salmon returned to the Ocean River and a total of 23 marmosets were made. The test results showed that the northern Yellow Sea had the possibility of habitat of large salmon, migratory ecological conditions and expansion and discharge of Dayang River.
