冬放鱼种是提高堰塘鱼产量的有效途径。投放鱼种的数量是否合理直接影响养鱼的经济效益。堰塘鱼种放养密度受产量、技术水平、品种、规格和堰塘环境条件等因素的制约,如何确定合理的放养数量呢?现介绍一种计算方法,供生产上参考。 1、根据堰塘条件、技术水平和养鱼户的经济基础,订出计划达到的亩产量。如某堰塘参照本塘历年产量、邻近地区经验等确定本塘亩产鱼可达500公斤水平,此塘技术上主要采取投喂人工饵料养鱼方 Winter release of fish species is an effective way to raise weir pond fish production. Whether the number of fish species put into play directly affects the economic benefits of fish farming. Weir pond stocking density by the yield, technical level, variety, specifications and weir pond environmental conditions and other factors, how to determine the reasonable stocking quantity? Now introduced a calculation method for the production of reference. 1, According to weir pond conditions, technical level and economic base of fish farmers, set the plan to achieve the mu production. Such as a pond with reference to the pond calendar year production, experience and other nearby areas to determine the pond mu fish up to 500 kg level, the pond technically fed artificial fish feed
