草鱼为典型的草食性淡水鱼类,传统的养殖方法是人工割草喂养,一年养一季,但这种养殖模式劳动强度大,产量低,效益不高,一般亩产250kg-400kg,1年亩利润仅800元-1000元。为走科技兴渔之路,加大淡水养殖科技含量,努力提高内陆山区淡水养殖的经济效益,增加农民经济收入,福建省古田县水产技术推广站自2003年起在重点渔业村采用自动投饵机定点、定时、间歇式自动投喂人工颗粒饲料进行池塘半机械化主养草鱼,一年养两季,取得平均亩产1960kg,养殖成活率95%以上,一年亩利润3000元的成绩,一般1个劳动力可以管理10亩池塘,其主要技术如下:
Grass carp is a typical herbivorous freshwater fish. The traditional breeding method is artificial mowing and raising one season a year. However, this breeding mode has the advantages of high labor intensity, low yield and low efficiency. Generally, it yields 250kg-400kg per mu for 1 year The profit of only 800 yuan -1000 yuan. In order to take the road of rejuvenating and rejuvenating science and technology, increase the scientific and technological content of freshwater aquaculture, make efforts to increase the economic benefits of freshwater aquaculture in inland mountainous areas and increase the economic income of farmers, the Gutian County Fishery Technology Extension Station in Fujian Province has adopted automatic injection Bait machine fixed point, timing, intermittent automatic feeding of artificial pellet feed pond semi-mechanized main grass carp, raising two seasons a year, made an average yield of 1960kg, breeding more than 95% survival rate, 3,000 acres of profits a year results, A general workforce can manage 10 acres of ponds, its main technology is as follows:
