Problems solved by technology

[0005] 2. Physical decline: Grass carp do not eat or eat less in winter, the fatty acids and trace elements accumulated in the body are exhausted, the immunity of the fish body is significantly reduced, and the physical fitness is reduced; the water temperature rises in spring, the water quality deteriorates, and bacteria and parasites breed. Fish are very prone to disease, and the effect of this nutritional problem is not good even if a lot of money is spent on medicine
[0006] 3. High mortality rate: Although the incidence rate of fish in winter is low, the mortality rate is high after spring
Because the fish price is generally bullish in March and April of the following year, but less feeding in winter leads to insufficient listing specifications; in order to go on the market as soon as possible, farmers increase the feeding rate impatiently, which leads to stress on the fish body, damage to the digestive system and immune organs, Grass carp has even become a "porcelain doll". When the fish is sold, the fish will die as soon as the net is scraped. In addition to the later treatment costs, the loss is heavy

Abstract

The invention discloses feed for overwintering domestication of a grass carp. The feed is prepared from, by weight, 22-28 parts of Hebei wheat, 15-18 parts of hulled soybean meal, 15-25 parts of fermented soybean meal, 12-15 parts of soybeans, 12-18 parts of fish meal, 1-2 parts of monocalcium phosphate, 3-8 parts of fish soluble, 0.05-0.2 part of enzymic preparations, 0.5-2 parts of decavitamin and 0.5-2 parts of composite minerals. The invention further discloses a preparation method of the feed for overwintering domestication of the grass carp. The invention further discloses a grass carp overwintering culture method. The method comprises the steps of feeding the feed for overwintering domestication of the grass carp and the like. The feed for overwintering domestication of the grass carp is low in protein, high in fat and high in vitamin and mineral substance, the culture method is provided, and therefore the flesh losses of the grass carp can be reduced, the survival rate can be increased, and the overwintering culture risk is greatly reduced.

Description

technical field [0001] The invention relates to a fish breeding feed and a fish breeding method, in particular to a grass carp overwintering domestication feed and a preparation method thereof, and a grass carp overwintering breeding method. Background technique [0002] Grass carp is often used as the main stocking object for pond culture and lakes, reservoirs and rivers because of its simple feeding habits, wide range of bait sources, rapid growth and high yield. As the scale of grass carp farming in our country expands year by year and the unit output increases, the total supply of grass carp continues to increase, and the supply of grass carp has already appeared in a state of oversupply, resulting in a very low price of grass carp at the end of each year when grass carp is concentrated on the market, so many In order to obtain a higher price of grass carp, the farmers continue to breed the fish until March to April of the following year before going on the market one af...
