投饵量目前,饵料费一般占养虾总成本的60～70%。要提高养虾的经济效益,降低饵料费是关键因素之一,而正确掌握投饵量是降低饵料成本的有效措施。池养对虾投饵少时,不能满足对虾的营养要求,对虾生长迟缓,个体小,产量低,经济效益不大,甚至亏本。但多投饵,对虾并不能与投饵量成比例地增长,反而会提高养虾成本和污染水质。要准确掌握投饵量,须先了解虾的摄饵 At present, bait fee generally accounts for 60 ~ 70% of the total cost of shrimp farming. To raise the economic benefits of shrimp farming, reduce the cost of bait is one of the key factors, and the right to grasp the amount of bait is to reduce the cost of effective measures. Pond prawn feeding less time, can not meet the nutritional requirements of prawn, prawn growth retardation, individual small, low output, economic benefits, or even loss. However, more feeding, shrimp and feeding volume can not be increased in proportion to, but will raise the cost of shrimp and pollute the water quality. To accurately grasp the amount of feeding, we must first understand the shrimp bait
