一、前言中华绒螯蟹(Eviochein Sinensis)俗称河蟹,营养物质含量甚为丰富。近年来,已在我国池塘推广养殖,发展较快。但在饲养过程中,人们常以动物性或精饲料为主进行投喂,这两种饲料成本高且来源有限,从而限制了养蟹业的进一步发展。因此,结合我国饲料资源特点和河蟹生物学特性。开展河蟹对饲料营养需求和利用率的研究,已日益受到人们的重视,但目前有关这方面的研究报道甚少。本试验分别以青饲料、精饲料、混合饲料投喂河蟹进行饲养,并以动物性饲料组作对照,旨在探讨其对河蟹的生长和肉质影响,为开发广阔的饲料资源,降低生产成本,提高经济效益,提 I. Introduction Eriocheir sinensis (Eviochein Sinensis) commonly known as crab, nutrient content is very rich. In recent years, it has been popularized in ponds in our country and developed rapidly. However, during feeding, people often feed mainly on animal or concentrate feeds, which have high costs and limited sources, thus limiting the further development of crab farming. Therefore, combining the characteristics of China’s feed resources and crab biological characteristics. Research on the demand and utilization of feed for crabs has been paid more and more attention by people. However, there are few reports on this aspect. In this experiment, crabs were fed on green fodder, concentrate feed and mixed fodder, respectively. The animal fodder group was used as a control to explore the impact on the growth and meat quality of crabs. In order to develop broad feed resources, reduce production costs and improve Economic benefits, mention
