THE RATIONAL DESIGN OF POND FISH CULTURE WITH REFERENCE TO THE PRINCIPLES OF YIELD INCREASE Ⅲ. COMPOSITION AND QUANTITY OF FOOD SUITABLE FOR THE GROWTH OF GRASS CARP

  • 摘要: 在实验室以浮萍和苏丹草为青饲料,颗-1(蛋白质17%)和颗-2(蛋白质25%)为精饲料进行交叉梯度试验,用特定生长率、饲料总生长效率、蛋白质效率等作为评价指标,试验结果表明:草鱼种所需青饲料与颗-1、颗-2的适宜比例范围分别为20—50,1和15—30:1。根据上述试验结果,兼顾草鱼在不同季节的营养需求和控制池塘水质,调整各阶段青、精饲料的投喂量,于1987—1989年进行了池塘对比饲养试验,结果表明,青、精饲料的平均投喂量分别为11.25×104—12.00×104kg/ha和11.25×103—12.00×103kg/ha,试验池草鱼生长率、总体鱼增重量分别为常规池的1.4和1.5倍。

     

    Abstract: Grass carp fingerlings were fed in laboratory aquaria on different combinations of green feed (duckweed or Sorghum sudanense) and pelleted diets (17% protein in diet No. 1 and 25% protein in diet No. 2). Both the species of green feed and the type of pelleted diet affected the growth rate of the fish. Judged from growth rate, gross growth efficiency, protein efficiency ratio and other indices, the optimal proportion of green feed to pelleted diet was 20—50:1 when pelleted diet No. 1 was used, and 15—30: 1 when pelleted diet No. 2 was used. Pond experiments were conducted during 1987—1989, The proportions and quantities of green feeds and pelleted diets were adjusted on the basis of laboratory redults, the nutrient requirements by the grass carp in different growth stages and seasons, and the water quality requirement for the prevention of diseases. In the experimental ponds, the annual inputs of green feeds and pelleted diets were 11.25×104-12.00×104kg/ha and 11.25×103-12.00× 103kg/ha, respectively. The growth rate of the grass carp and the total weight gain by fish were 1.4 and 1.5 times, respectively, those in the control ponds using ordinary feeding regimes.
