在毛主席革命路线的指引下,家鱼人工繁殖有很大的发展和普及。为进一步提高亲鱼的产卵量,近年来对于草、鳙、鲢一年多次催产,己分別由广东兴宁鱼苗场,湖北滠口养殖场和安徽泗县渔场试验成功。为了增加鱼苗产量和验证家鱼一年多次产卵的问题,我所今年进行了草鱼一季二次产卵的试验,并取得了初步成功。现将试验结果报告如下,请批评指正。 Under the guidance of Chairman Mao’s revolutionary line, there has been great development and popularization of artificial reproduction of domestic fish. In order to further enhance the fecundity of broodstock, grass, 鳙, and silver carp have been successfully induced many times a year in recent years by Xingning Fish Farm in Guangdong, oukou farms in Hubei Province and fisheries in Si County, Anhui Province. In order to increase the production of fry and verify that fish spawn more than once a year, this year we conducted a trial of laying eggs in the grass for one season and achieved initial success. The test results are reported as follows, please comment on the correction.
