Abstract: Feeding habit is one of the important traits affect the growth of fish, it is also an important content in the study of genetic improvement. Diets is regulated by many factors, not only with the intrinsic genetic and physiological factors such as appetite, the structure of the digestive tract, but also external bait properties such as sources of protein, feed palatability and so on; Relating genes of genetic manipulation is the major determinant of diets. Size of the farming industry of the fish especially carnivorous fish could be enlarged by improvement of the feeding, urging the fish depending on the ice fresh feeding or the live fish to receive breeding artificial feed, and the economic benefits of aquaculture industry will be improved a lot. This article summarizes the fish feeding of gene regulation and improvement, combining with feeding related gene polymorphism and artificial feed protein source in order to provide help to the genetic improvement of fish feeding .
