Method for breeding loaches in greenhouse pond

Abstract

The invention relates to a method for breeding loaches in a greenhouse pond. According to the method, a greenhouse is used for breeding, a wind deflector is used for introducing air, a breeding pond is divided into an inner layer and an outer layer, and an aerator is used for conveying the introduced air to a cavity; then the air is introduced into the breeding pond for oxygenation through a gas-guide tube. The method is pioneering in loach breeding, and the survival rate and growth rate of loaches are greatly improved. Polyethylene thin film is laid on the bottom and the periphery of the breeding pond, so that the loaches are subjected to soilless breeding, and the incidence rate and death rate of the loaches are lowered; when the loaches grow to 4 cm or longer, the loaches are bred in a large-area breeding pond, the difficult problem of dead loaches in small size is effectively solved, and the economic benefit of loach breeding is improved. By adoption of the method, the survival rate of the loaches reaches 98% or above, the growth speed is obviously improved, and the yield of the loaches with good quality is obviously improved.

Description

technical field [0001] The invention relates to a method for cultivating loach, in particular to a method for cultivating loach in a greenhouse and pond, belonging to the field of aquatic animal cultivation. Background technique [0002] Loach (scientific name: Misgurnus anguillicaudatus), belongs to Loach family. The body is small, slender, only three or four inches. Moreover, it has a round body, short body, small scales under the skin, black in color, and is covered with its own mucus, so it is slippery and difficult to hold. The anterior segment is slightly cylindrical. The rear is flattened. The scales are extremely small, round and buried under the skin. The back of the body and both sides are gray-black, and there are many small black spots on the whole body. There are also many black spots on the head and each fin. The spots on the dorsal and caudal fin membranes are arranged in rows, and there is an obvious black spot at the base of the caudal peduncle. The oth...

Problems solved by technology

However, the deterioration of water quality caused by soil farming cannot be fundamentally improved by measures such as changing water, substrate improving agents, and microbial preparations, unless the soil is removed. Especially in the middle and late stages of breeding

[0004] Therefore, soilless culture of loach is the development trend of loach culture in the future, but at present, soilless culture of loach mainly uses cement pond or net cage for soilless culture in production, but the cost of cement pond is high, and net cage culture is easy to block the mesh. The Soilless Culture Technology of Loach Needs to be Further Perfected Urgently
