Embodiment 1

[0023] (1) Requirements for the breeding pond: the breeding pond requires convenient drainage and irrigation, convenient transportation and electricity, no pollution to the water source and the environment, an area of ​​6 acres, a pond depth of 1.5-1.8 meters, a pond slope ratio of 3:1, and a pond bottom silt ≤ 20 cm. flat;

[0024] (2) Clean up the breeding pond: configure an aeration machine for every 3 mu of breeding pond, plant aquatic plants in a shallow water zone 1 meter away from the fish pond and fix them with ropes, splash quicklime once a month before fish species are stocked for disinfection, and Sprinkle quicklime again for disinfection one week before stocking, and add new water after filtering through the screen to prevent predators and other fish eggs from entering. The water injection depth is 2-2.5 meters, and the water quality requires a pH value of 7-8;

[0025] (3) Selection of fish species: choose lively and robust fish species with strong disease resista...

Embodiment 2

[0032] Embodiment 2 is a preferred version. Unlike Example 1, the present embodiment provides the formula of the pellet feed, and the pellet feed includes the following components by weight: 28 parts of soybean meal, 19 parts of bran, and 6 parts of vegetable protein , 15 parts of rapeseed meal, 11 parts of fish meal, 7 parts of wheat germ, 2 parts of calcium dihydrogen phosphate, 0.5 parts of multivitamins, 1.5 parts of traditional Chinese medicine additives, and 1.2 parts of salad oil.

[0033] Soybean meal, bran and rapeseed meal are mixed as the basic components of the feed to provide basic nutrients such as protein and sugar for domestic fish. Plant protein, wheat germ and fish meal can provide rich vitamins and minerals for domestic fish. The main raw material of protein is easily absorbed by domestic fish, and the energy conversion in the body of domestic fish is relatively high. Dicalcium hydrogen phosphate is combined with the multivitamin in domestic fish feed to sup...

Embodiment 3

[0035] Example 3 is a further embodiment of Example 2. In this example, the traditional Chinese medicine additives include 0.7 parts of astragalus, 2 parts of Codonopsis pilosula, 4 parts of honeysuckle, 4 parts of poplar, 2 parts of kudzu root and 8 parts of Acanthopanax.

[0036] The salad oil is selected from one or more of soybean salad oil, rapeseed salad oil, rice bran salad oil, cottonseed salad oil, sunflower seed salad oil or peanut salad oil.

[0037] The multivitamins include 2-3 parts of vitamin A, 0.4-0.7 parts of vitamin D3, 15-16 parts of vitamin E, 0.4-0.8 parts of vitamin B1, 0.1-0.3 parts of folic acid, and 0.4-0.6 parts of biotin.

Abstract

The invention discloses an aquacultured fish mixed culture method. The method comprises satisfaction of aquacutural pond requirements, preparation of the aquacutural pond, selection of fish fingerling, fish body disinfection, reasonable stocking, breeding, water quality control and appropriate fishing. The method ensures that variety is various through mixed culture of fish fingerling living at different depths of a water area, effectively utilizes space at different water depths in a fish pond, not only improves the aquaculture quantity, but also increases income of fishermen through orderedfishing in batches.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for polyculture of domestic fish. Background technique [0002] The fish polyculture method is a kind of production activity of reproduction and cultivation under artificial control, which generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. Polyculture of multiple fish species in the same fish pond is an important measure to increase fish production in ponds, and it is also a distinctive feature of pond fish culture. The polyculture of these fishes in the same pond can make full use of each water layer of the pond, and comprehensively and rationally utilize various feed resources of the pond. [0003] In recent years, my country's fish farming industry has developed rapidly, and the degree of intensification has been continuously improved. However, in the process of fish farming, people have used various chemic...
