虹鳟养殖在国外已有百余年历史,理论和实践上均有深入的研究,包括人工繁殖在内的整个生产过程已规范化。我国引进虹鳟鱼虽有20多年,由于种种原因,发展缓慢,总体上说,仍处在实验阶段。虹鳟人工繁殖技术在黑龙江、北京、山西等地多年来成功地应用于生产,特别是黑龙江水产研究所试制出垂直流水的柜式孵化器,从法国引进了桶式孵化器与丹麦式平列槽孵化技术,取得良好效果。我们为了取得虹鳟鱼在我区人工繁殖的直接经验,于1985年初,利用83年引进鱼种培育的亲鱼,进行了人工授精和孵化
Rainbow trout breeding has been in foreign countries for more than one hundred years of history, both in theory and in practice, and the entire production process including artificial breeding has been standardized. Although more than 20 years of introduction of rainbow trout in our country, due to various reasons, its development is slow. On the whole, it is still in the experimental stage. Rainbow trout artificial propagation technology in Heilongjiang, Beijing, Shanxi and other places for many years successfully applied to the production, especially the Heilongjiang Institute of Fisheries trial production of vertical flow cabinet incubator, introduced from France, a barrel incubator and the Danish-type flat-tank incubation technology , Achieved good results. In order to obtain the direct experience of artificial breeding of rainbow trout in our district, we conducted artificial insemination and hatching in early 1985 using broodstock raised in fish species introduced in 1983
