Problems solved by technology

[0004] The physiological characteristics of fish are that the digestive tract is short, and the food stays in the digestive tract for a limited time. It is difficult for the nutrients in the food to be completely absorbed by the body in a short period of time. environment, and is highly susceptible to disease

Embodiment 1

[0082] Defatted Fish Meal

[0083] Prepare powdered feed according to the formula shown in the above table, add water according to 30% of the total weight of each component of the powdered feed, add fish oil according to 5% of the total weight of each component of the powdered feed, stir evenly, and make it with a soft pellet feed machine Soft granule feed, uniform in color, stable and moderate in granule water, feeding speed and growth rate are the same as whole fishmeal feed, and can promote gonad development and maturation. The feed has the advantages of low cost, non-toxic, pollution-free, etc., and is suitable for feeding 3-5-year-old female sturgeon.

Embodiment 2

[0085] Defatted Fish Meal

[0086] Prepare powdered feed according to the formula shown in the above table, add water according to 30% of the total weight of each component of the powdered feed, add fish oil according to 5% of the total weight of each component of the powdered feed, stir evenly, and make it with a soft pellet feed machine Soft pellet feed, uniform in color, stable and moderate in pellet water, feeding speed and production speed are better than whole fishmeal feed, and can improve the gonad development of female fish. The feed has the advantages of low cost, non-toxic, pollution-free, etc., and is suitable for feeding 4 to 6-year-old female sturgeon.

Embodiment 3

[0088] Defatted Fish Meal

[0089] Prepare powdered feed according to the formula shown in the above table, add water according to 35% of the total weight of each component of the powdered feed, add fish oil according to 3% of the total weight of each component of the powdered feed, stir evenly, and make it with a soft pellet feed machine Soft granule feed, uniform color, stable and moderate granule water, feeding speed and production speed are better than whole fishmeal feed, can improve the spawning ability and egg quality of female fish, improve the flavor of caviar, and improve the quality of caviar. This feed is suitable for feeding female fish that are used to extract eggs to make caviar that year.

Abstract

The invention discloses compound feed for female parent fish of sturgeons. The process lies in that raw material components are processed into a mixture according to a powder feed processing method and extruded and pelletized after mixing with water and fish oil; the raw material components of the powder mixture include defatted fish meal, a-starch, extruded soybean, extruded corn, oligopeptide soybean meal, oligopeptide fish solution powder, feather peptide powder, beer yeast, minerals, multi-vitamins for fishing, choline chloride, monocalcium phosphate and the like. Compared with other sturgeon feed, the compound feed has the advantages that the content of protein oligopeptides is obviously increased, the amount of fish meal is decreased significantly, breeding cost is reduced, and foodattraction and nutrition can be improved; by the arrangement, the nourishing state of female parent fish population of sturgeons can be greatly improved, maturation of gonads in the female parent fishof the sturgeons is promoted, and breeding performance such as the quantity and quality of eggs is improved.

Description

technical field [0001] The invention relates to the field of aquatic product compound feed, in particular to the field of powdered compound feed for eel. Background technique [0002] With the rapid development of the aquaculture industry, the demand for fishmeal, which is the main protein source of aquafeed, is constantly increasing, resulting in tight supply and demand, and the price is rising year by year. To solve this contradiction, in addition to increasing the development and utilization of new protein resources, it is also very important to rationally utilize protein resources, realize further balanced preparation of diets, improve the utilization rate of existing protein raw materials, and reduce blind waste. [0003] In the 1990s, my country began large-scale breeding and breeding of sturgeons, and the breeding industry developed rapidly. At present, my country has become the world's largest country for raising sturgeons. The rapid development of the sturgeon aqua...
