Problems solved by technology

[0003] However, due to the increasingly harsh natural environment and serious water pollution, the output of tingling fish is declining year by year, and the market price is as high as more than 300 yuan per kilogram. Natural resources can no longer form a group output.

Embodiment 1

[0016] A nano slow-release compound fishery nutrient feed is characterized in that the feed comprises the following components in parts by weight: 30-35 parts of high-protein potato powder, 15-25 parts of rice bran, 10-20 parts of peanut shells, multivitamin 5~7 parts, 4~6 parts of calcium dihydrogen phosphate, 0.5~1.5 parts of oxytetracycline;

[0017] The multivitamins include vitamin b1, vitamin b6, vitamin b12, vitamin c, vitamin d3, vitamin e and vitamin k;

[0018] Multivitamins include vitamin b1 20%, vitamin b6 10%, vitamin b12 10%, vitamin c 20%, vitamin d3 10%, vitamin e 20%, vitamin k 10%.

[0019] Preferably, the feed comprises the following components in parts by weight: 10 parts of chitosan fiber, 5 parts of sodium alginate, 20 parts of high molecular weight chitosan, 5 parts of ethylenediamine tetraidene phosphoric acid, -ketopentamethylene 5 parts of diacid, appropriate amount of water, 30 parts of high-protein potato powder, 15 parts of rice bran, 10 parts of...

Embodiment 2

[0026]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 avoid stress response of the fish body and reduce the disease resistance of the fish body; take corresponding disease prevention measures to avoid the introduction of disease;

Abstract

The invention discloses a nanometer sustained-release compound aquaculture feed and a feeding method thereof. The nanometer sustained-release compound aquaculture feed is prepared from the following component in parts by weight: 30-35 parts of high-protein-content whole potato powder. The nanometer sustained-release compound aquaculture feed and the feeding method thereof are complete in protocol and simple in technology. The feeding technology and the rationally matched multiple raw materials in the feed are coordinated, so that the nutrients in the raw materials are mutually complementary; thus, the feed is high in protein content. The chitosan is a kind of natural macromolecular polysaccharide, and has the performance characteristics that the chitosan is wide in source, non-toxic, tasteless, good in biocompatibility, good in biodegradation, and good in antibacterial properties and so on. Thus, the feed is rich and comprehensive in nutrients, good in palatability, low in feed coefficient, and capable of improving immunity and antioxidant capacity of the tinca tinca. Moreover, the tinca tinca fed with the feed is high in survival rate.

Description

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