Embodiment 1

[0016] The feed for feeding tingman fish is composed of feed attached to the surface of the slow-release material, wherein the slow-release material includes the following total amount of raw materials: 10 parts of chitosan fiber, 5 parts of sodium alginate, polymer chitosan 20 parts of sugar, 5 parts of ethylenediamine tetraidene phosphoric acid, 5 parts of -ketoglutaric acid, appropriate amount of water, take the above ratio of ethylenediamine tetraidene phosphoric acid and add 4 times of water, heat at 50°C and stir until uniform , then continue to slowly add chitosan fiber, stir until completely dissolved, and add sodium alginate, heat up to 80°C and stir until uniform, after homogeneous cooling, a coating solution is obtained for later use;

[0017] Take a solution of the coating film into 3 times the water, heat to 60 ° C and stir until uniform, then continue to slowly add polymer chitosan, stir until completely dissolved, and add -ketoglutaric acid, and then add the foll...

Embodiment 2

[0023] Choose a "mouth" type fish farm with good water retention and shelter from the wind and facing the sun. After cleaning up the garbage, use chemical methods to monitor the water quality. If chemical pollutants need to be removed by chemical methods, set up anti-escape nets, among which the anti-escape nets are 40-60 mesh , mix cow dung or green manure under the silt, and put in aquatic plants and dead wood. Among them, the planting density of aquatic plants is 2~5 catties / m 2 Disinfect the fish fingerlings unloaded from the truck with sodium chloride solution or sodium hypochlorite solution. The method of use is to soak the fish fingerlings in sodium chloride solution or sodium hypochlorite solution for 5-10 minutes After sorting, the female fish and the father fish are put into the fish pond separately and put into the feed;

[0024] Adopting the method of the present invention to carry out refined breeding, the process of attaching the effective feed to the slow-release...

Abstract

The invention discloses nano chitosan composite nutrient fodder and a feeding method. The fodder comprises, by weight, 30-35 parts of high-protein potato powder, 15-25 parts of rice bran, 10-20 parts of peanut shells, 5-7 parts of composite vitamins, 4-6 parts of monocalcium phosphate and 0.5-1.5 parts of oxytetracycline. According to the nano chitosan composite nutrient fodder and the feeding method which are provided by the invention, the scheme is complete; the process is simple; the breeding process and the multiple raw materials used in the fodder are reasonably collocated in a matched mode, so that the nutritional components of the various raw materials are complementary, and the protein content is high; and the fodder is rich and comprehensive in nutrition, good in palatability, low in coefficient and capable of improving the immunity and the antioxidant capacity of tench tinca tinca, so that the survival rate of the tench tinca tinca is high.

Description

technical field [0001] The invention relates to the field of fish breeding, in particular to a nano-chitosan compound nutrient feed and a feeding method. Background technique [0002] Dinggui fish has four colors of green, yellow, blue, and white on the surface. It also has tender meat, delicious taste, and high nutritional value. It is one of the main freshwater aquaculture economic fish in European countries, and it is also an important Sport fishing and ornamental fish are known as royal pet fish in Europe. Because the body color quickly turns black after being caught, it is called "black fish". Omnivorous and sticky eggs are two major characteristics. It is an important economic fish and has high ornamental value. Potatoes have complete nutrients and are easily absorbed. In France, potatoes are called "underground apples". What we eat daily is underground tubers, which are rich in starch, protein, sugar, mineral salts and vitamins, especially carotene and ascorbic aci...
