Example Embodiment

[0022] Example 1

[0023] (1) Breeding pond requirements: The breeding pond requires convenient irrigation and drainage, convenient transportation and electricity, and pollution-free water source and environment. It covers an area of ​​6 acres, a pond depth of 1.5-1.8 meters, a slope ratio of 3:1, and silt at the bottom of the pond ≤ 20 cm and the bottom of the pond. flat;

[0024] (2) Clean up the aquaculture pond: equip an aerator for every 3 acres of aquaculture ponds, plant aquatic plants in shallow water 1 meter away from the fish ponds and fix them with ropes. Sprinkle quicklime once a month before stocking the fish for disinfection. Sprinkle quicklime again for disinfection a week before stocking, add new water after filtering with a screen to prevent entry of predators and other fish eggs. The water injection depth is 2-2.5 meters, and the water quality requires a pH of 7-8;

[0025] (3) Fish species selection: choose lively, robust and disease-resistant fish species, includ...

Example Embodiment

[0031] Example 2

[0032] Example 2 is the preferred solution. The difference from Example 1 is that this example gives the formula of pellet feed. The step 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 Chinese medicine additives, 1.2 parts of salad oil.

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

[0034] Example 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, 4 parts of Honeysuckle, 4 parts of Poplar Flower, 2 parts of Pueraria lobata Root and 8 parts of Acanthopanax senticosus.

[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] 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...
