近几年来,我国对鱼类营养生理方面的研究逐步重视,并已查明了草鱼对几种主要营养物质的需要量。这些研究结果对于发展草鱼的配合饲料具有重要意义,也为鱼饲料工业的发展提供了理论依据。但是,对于草鱼摄食和利用配合饲料的规律如何,未见有报道。然而,这方面的知识对于确定饲养技术以及提高饲料的转换率和养鱼的经济效益等都是十分必要的。本研究的目的在于掌握草鱼摄食和利用膨化颗粒饲料的特性,为在养鱼生产中准确地投饵提供依据。
In recent years, our country has paid more attention to the research of nutrition and physiology of fish and has identified the demand of several main nutrients of grass carp. These findings are of great significance for the development of compound feed for grass carp and provide a theoretical basis for the development of the fish feed industry. However, there is no report on the law of grass carp feeding and using compound feed. However, this knowledge is essential for the identification of feeding techniques and for the improvement of feed conversion rates and the economic benefits of fish culture. The purpose of this study is to master the characteristics of feeding and utilization of puffed pellets for grass carp, and provide the basis for accurate feeding in fish production.
