Problems solved by technology

Therefore, the quality, plumpness, and survival rate of fingerlings in the overwintering stage will affect the breeding of adult fish in the coming year, and indirectly affect the economic benefits of farming.
Judging from the existing patents and papers, there are basically no reports of overwintering feeds, and currently there are few feeds for heterogeneous gibel crucian carp in the market. The main use of conventional commercial feeds is to feed fish bodies, which will easily cause a large waste of feed and easily pollute the water body. , increase the cost of feed and affect the survival rate of fish species

Abstract

The invention discloses an overwintering feed for carassius auratus gibelio and a preparation method thereof. The overwintering feed has the advantages that as wheat, expanded soybeans, expanded blood meal, rapeseeds and the like are added to the feed, the capability of carassius auratus gibelio in converting starch to fat is improved, and carassius auratus gibelio converts starch to fat needed by self, so the requirement of fish bodies for storing energy is met and the fatness of the fish bodies is improved, and then the feed cost can be effectively controlled; as additives such as L-carnitine, brewer's grains, garlic and the like are added, the feed has the functions of resisting cold and stress and killing harmful bacteria, has a certain food attracting function, improves the palatability, and is favorable for reducing the food coefficient of the carassius auratus gibelio and increasing the survival rate of the carassius auratus gibelio; and the selected raw materials are sufficient in sources, the production process is simple, and the feed is not easy to deteriorate and is convenient to transport and preserve.

Description

technical field [0001] The invention relates to a heterogeneous gibel crucian carp overwintering feed and a preparation method thereof, belonging to the technical field of aquatic product compound feed. Background technique [0002] Allogenetic gibel carp ( Carassius auratus gibelio ) is the offspring bred by artificial insemination using the Founder gibel crucian carp as the female parent and the Xingguo red carp as the male parent using natural gynogenetic development. It has good heterosis, obvious effect of increasing production, tender meat, rich nutrition, long survival time out of water, wide appetite, easy feeding, strong adaptability and high survival rate. More than 30 provinces, municipalities and autonomous regions in the country have introduced and cultured heterogeneous gibel carp. In 2010, the production of heterogeneous gibel carp reached about 2.216 million tons. One of the categories, the economic benefits are very significant, and are very popular among ...
