摘要
本文调查了河蟹生态养殖中动物性饵料投喂数量,分析了动物性饵料量与河蟹每667m2产量、平均规格和每667m2利润的关系,提出了河蟹生态养殖中动物性饵料量的数学模型,初步确定了动物性饵料的合理投喂量、饵料系数和蛋白质需要量的参考值。
In this paper, we investigated the quantity of animal bait in ecotypic breeding crabs, analyzed the relation between the quantity of animal bait and mature average weight of single carbs,yield,profit of 1/15hm^2, put froward a mathematical model of animal bait and provided the logical quantity and coefficient of animal bait and reference values of requisite protein during ecotypic breeding crabs.
