绥芬河水域是黑龙江省的一条独立水系,主要流经东宁县由绥芬河下水磨河段入苏联境内,自海参崴入日本海。绥芬河是大麻哈鱼和鲤科唯一溯河洄游鱼——滩头雅罗鱼的溯河繁殖的母河川。近年来绥芬河水域的水产资源也遭到严重的破坏,特别是名贵经济鱼类大麻哈鱼的产量下降到每年只有800—1000尾。为了增殖绥芬河水域大麻哈鱼资源,恢复绥芬河母河川,1988年建立起东平县鲑鱼放流站。并于当年春季首次向绥芬河放流驼背大麻哈鱼苗80万尾,其中做标志鱼3万尾。今年6月至8月是放流驼背大麻哈鱼的洄游季节,黑龙江省水产研究所和东宁县鲑鱼放流站对这一人工放流科研项目进行了调查。截止今年8月末,已在绥芬河下水磨河段捕到驼背大麻哈鱼610尾,平均体重0.95—1.5公斤,平均体长40—50厘米,其中做放流标志的鱼5尾,被剪掉的仔鳍没有再生长出
Suifenhe is an independent water system in Heilongjiang Province. It mainly flows through Dongning County from Suifenhe River into the Soviet Union, and from Vladivostok to the Sea of Japan. Suifenhe is the only river upstream of salmon and saltwater migratory fish - beach head Arhats, the mother river upstream. In recent years, the aquatic resources in the Suifenhe River have also been seriously damaged. In particular, the production of salmon, a precious economic fish, has dropped to only 800-1000 fish per year. In order to multiply the salmon resources in Suifenhe and restore the mother river of Suifenhe, the Dongping County Salmon Release Station was established in 1988. In the spring of the year, for the first time, 800,000 humpback saliva were salvaged to Suifenhe, of which 30000 were marked as fish. From June to August this year, the migratory season for saliva salmon was released. The Heilongjiang Provincial Institute of Fisheries and the Dongning Salmon Release Station investigated the project. Up to the end of August this year, 610 humpback saliva had been caught in the Sanhui section of the Suifenhe River with an average body weight of 0.95-1.5 kg and an average body length of 40-50 cm. Among them, 5 were used to release the fish and 5 were cut off Fins did not grow out
