Problems solved by technology

[0003] Because the feeding methods and feeding habits of different species of fish in different waters are different, and even the feeding methods and feeding habits of the same species of fish are different at different developmental stages. During the breeding process, the cultured fish grow slowly, are prone to disease, and have low economic benefits

Embodiment 1

[0028] A kind of mountain pond polyculture method of lobster, silver carp and bighead carp proposed by the present invention comprises the following steps:

[0029] A. Select a polyculture pond: choose a reservoir with a transparency of 30cm, a pH of 8.5, a water depth of 2.5m, an area of ​​250 mu, fresh water quality, no pollution sources, convenient drainage and irrigation, and supporting power as a polyculture pond, and equipped with 13 sets 2200W aerator;

[0030] B. Clean up the polyculture pond: Drain the water of the polyculture pond and dry the pond. After the polyculture pond is dried, remove the weeds around, clean up the silt at the bottom of the pond to make the thickness of the silt be 10cm, level the bottom of the pond and tamp the ridge , Block the loopholes, dredge the inlet and outlet, set a 55-mesh mesh at the inlet to filter the water, to prevent wild fish and other fish eggs from entering, and set a block at the outlet to prevent the escape of farmed fish; ...

Abstract

The invention discloses a pool polyculture method for tor brevifilis, flying carps and bighead carps. The pool polyculture method comprises the following steps of selecting a polyculture pool; neatening the polyculture pool; fertilization: applying fermented chicken droppings as a base fertilizer, topdressing EM bacterium and unicellular alga activin after 3-4 days, and adding urea and calcium superphosphate; putting: in January, disinfecting with quick lime and putting flying carps and bighead carps after 12-18 days, wherein the density of the flying carps is 90-110 fishes / mu and the density of the bighead carps is 45-55 fishes / mu; in the first ten days of June, putting the tor brevifilis, the density of the tor brevifilis is 3200-3700 fishes / mu; feeding and management: feeding the granulated feed accounting for 4-7wt% of the weight of the tor brevifilis; water quality management: changing and adding water and using a microbial preparation in the feeding process; disease control: disinfecting with quick lime at intervals of 15 days; from the start of July, killing pests by adopting o, o-dimethyl (2, 2, 2-trichlorine-1-hydroxy ethyl) phosphonate, and adding allicin and isatis root in the fed feed; daily management.

Description

technical field [0001] The invention relates to the technical field of cultivation, in particular to a method for polyculture of lobster, silver carp and bighead carp in mountain ponds. Background technique [0002] Osteophytes belong to Osteostichthyes, Cyprinidae, Cyprinidae, Subfamily Cyprinidae, Osteophytes, and Osteophytes subgenus. They are widely distributed in the Lancang River, Yuan River, Yangtze River, Pearl River and other water systems in my country. They are only seen in Vietnam abroad. of the Red River system. The growth rate of the petaled fish is average. The body length of 1 winter age fish is 19-19.5 cm; the body length of 2 winter age fish is 27.6 cm; the body length of 3 winter age fish is 33.8-34.6 cm; 0.5-1 kg, up to 8 kg, is a large and medium-sized freshwater economic fish in the production area. [0003] Because the feeding methods and feeding habits of different species of fish in different waters are different, and even the feeding methods and fe...
