史氏鲟(Acipenserschrencki),达氏鳇(Husodauricus)属鲟科鱼类,是黑龙江的主要经济鱼类之一。由于近年来过度捕捞,资源遭到一定程度的破坏。本文主要通过对黑龙江某江段上的捕捞生产调查统计.评估其现有资源状况,并提出了五个方面的建议。同时介绍了我国目前对鲟鱼研究方面的进展情况。1957年黑龙江水产研究所成功地进行了史氏鲟的人工繁殖试验,以后除了五十年代和七十年代的一些调查工作外,基本上中断了对这条鱼的人工繁殖试验工作。1989年,黑龙江省国营农场总局在勤得到农场建立了第一个史氏的放流试验站,当年就进行了人工繁殖和放流工作。四年中,向黑龙江放流鲟鱼苗累计达107万尾。在此期间有关的科研和生产单位利用这一条件开展对鲸鱼的研究,本文还介绍了正在进行的“史氏鲟活体取卵手术技术研究”、“鲟幼鱼人工饲料研究”和“人工养殖技术研究”等。 Acipenserschrencki and Husodauricus belong to the family of sturgeon, one of the major economic fishes in Heilongjiang Province. Due to overfishing in recent years, resources have been destroyed to some extent. This article mainly through a section of Heilongjiang fishing survey statistics. Assess the status of its existing resources and make five recommendations. At the same time, the progress of sturgeon research in our country is introduced at the same time. In 1957, the Heilongjiang Institute of Fisheries successfully carried out the artificial propagation experiment of Amur sturgeon. Afterwards, apart from some investigations in the 1950s and 1970s, artificial breeding experiments on this fish were basically interrupted. In 1989, the State Farm Administration of Heilongjiang Province set up the first Shilsal release test station in Qinqin Farm and conducted artificial breeding and discharge of that year. In the past four years, a total of 1.07 million sturgeons were released to Heilongjiang. During this period, relevant research and production units used this condition to carry out the research on whales. This article also introduced the ongoing research on Survival Technique of Amur sturgeon, the research on artificial feed of sturgeon juveniles and artificial breeding Technical research "and so on.
