Embodiment 1

[0015] A kind of slow-release coating compound fishery feed, the feed for feeding dingmangus consists of feed attached to the surface of the slow-release material, wherein the slow-release material includes the following total amount of raw materials: chitosan fiber 10-20 5-10 parts of sodium alginate, 20-25 parts of polymer chitosan, 5-10 parts of ethylenediaminetetraethylene phosphoric acid, 5-8 parts of -ketoglutarate, appropriate amount of water, take the above ratio Add 4-5 times of ethylenediamine tetraidene phosphoric acid into water, heat at 50-55°C and stir until uniform, then continue to slowly add chitosan fiber, stir until completely dissolved, add sodium alginate, and heat up to 80-90 ℃ and stir until uniform, after homogeneous cooling, a coating solution is obtained for later use;

[0016] Take a solution of the coating film into 3-6 times of water, heat to 60-65 ° C and stir until uniform, then continue to slowly add polymer chitosan, stir until completely disso...

Embodiment 2

[0024] The longitudinal cross-section of the cultivation fish pond is trapezoidal, the transverse cross-section is circular, and the transverse cross-sectional area is 30 m 2, the depth is 1.2 m, the water circulation and sewage discharge performance are good, the water quality is clear, does not contain heavy metals, the salinity is 22~28, the total amount of E. Use bran to kill miscellaneous fish; use 2.5 mg / L crystal trichlorfon to kill miscellaneous shrimp; maintain water pH at 7.0~8.5; dissolved oxygen at 6 mg / L~8 mg / L; feed with satiety Hey, feed 3 times a day at 7:00, 14:00, and 20:00, and absorb the residue after 1 hour after feeding; the temperature difference of the fish body should not exceed 3°C when the fish is transferred, and the water change in the pond should not be too large. To prevent the fish body from producing a stress response and reduce the disease resistance of the fish body; take corresponding disease prevention measures to avoid the introduction of ...

Abstract

The present invention discloses a sustained-release film coated compound fishery feed and a feeding method thereof. The feed comprises the following components in parts by weight: 30-35 parts of high-protein potato full powder, 15-25 parts of rice bran, 10-20 parts of peanut shells, 5-7 parts of compound vitamins, 4-6 parts of calcium dihydrogen phosphates and 0.5-1.5 parts of oxytetracycline. The provided sustained-release film coated compound fishery feed is complete in scheme and simple in technology. The various raw materials used in the breeding technologically synergistic feed are reasonably matched, so that the various raw materials are complementary in nutrients. The feed is high in protein content, rich and comprehensive in nutrients, good in palatability, and low in feed coefficient, can improve the immune and antioxidant capacities of tinca tinca, and is high in survival rate.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a slow-release coated compound fishery 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...
