大规格鱼种是成鱼高产的物质基础。目前,草鱼种的培育则是一个薄弱环节。都昌县水产科学研究所熊杰存水产局工程师熊洪旭的指导下,通过一系列有效的技术措施,兼顾了品种、规格、产量三者的关系,在一口3.8亩池中,1991年培育出一龄大规格鱼种1538.5公斤,成活率达60.8%,亩平产冬片鱼种405公斤,其中草鱼种占43.1%,成活率达51.07%,规格在100克/尾以上,总产值达8005.9元,亩平产值2106.8元,亩平利润达1400元。为鱼种培育的高产、大规格、优质化闯出新路子。现将其主要技术措施介绍如下:
Large-scale species of fish is the material basis for high-yielding adult fish. At present, the cultivation of grass carp species is a weak link. Under the guidance of Xiong Hongxu, an engineer at Xiong Jiecun Bureau of Fisheries, Duchang County Fisheries Science Institute, through a series of effective technical measures, taking into account the relationship among varieties, specifications and yields, in a 3.8-acre pond, 1538.5 kilograms of standard species of fish species, the survival rate of 60.8%, mu flat-producing winter species 405 kg, of which 43.1% species of grass carp, the survival rate of 51.07%, specifications at 100 g / tail above, the total output value of 8005.9 yuan, mu The average output value of 2106.8 yuan, mu flat profit of 1,400 yuan. For breeding high-yield fish species, large format, high-quality break new path. Now the main technical measures are as follows:
