Problems solved by technology

However, the traditional way is to fish in paddy fields and ponds, and there is no large-scale breeding. With overfishing and the deterioration of habitats, the resources of loach are destroyed, and the natural output is greatly reduced. In order to increase effective supply and meet market demand, large-scale artificial breeding growing importance

Embodiment Construction

[0024] The parent loach is selected from natural waters. The winter age is 2-3 years. Body weight 30g or more; male loach 12cm, body weight 15g or more, inject artificial oxytocic agent, according to each female loach, human chorionic gonadotropin 100-150 international units, male loach halve; choose 1mL syringe and No. 4 needle, solvent The injection volume is 0.1-0.2mL, injected into the midline of the abdomen between the thoracic and pelvic fins; put 3000g of parent loach on 10 m 2 In the breeding grounds, including spawning hatching ponds and rearing ponds; to ensure the water demand of the breeding grounds, there should be 0.05-0.1m 3 / s flow rate, the water source is pollution-free, the breeding ground is disinfected, and fish nests are laid on the bottom of the pool; the water depth is kept at 25cm, and the water temperature is 20°C to promote the laying of eggs; the fish nests are taken out for natural hatching, and the water temperature does not exceed 20°C. Accordin...

Abstract

The invention relates to an artificial propagation method of West Asian loach, which comprises the steps of clearing and disinfecting a spawning pond, placing a nest, controlling water temperature and injecting hormone to stimulate spawning of parent loach, naturally incubating a spawn, controlling the density of young loach, performing reasonable feeding, and then transferring to an adult loach feeding stage when the loach grows to be about 3cm. The propagation method can effectively increase the yield of the young loach, increases an economic benefit, and promotes development of the loach propagation industry.

Description

technical field [0001] The invention relates to a method for artificial propagation of West Asian loach, in particular to a method capable of rapidly breeding a large number of large-scale breeding fry. Background technique [0002] Loach has another name called loach, belongs to fish class, Cyprinidae, Cyprinidae, Loach family, and the genus Loach. Tender meat, delicious taste, high-protein, low-fat nutritional treasures, high medicinal value, high economic benefits, great demand in domestic and foreign markets. However, the traditional way is to fish in paddy fields and ponds, and there is no large-scale breeding. With overfishing and the deterioration of habitats, the resources of loach are destroyed, and the natural output is greatly reduced. In order to increase effective supply and meet market demand, large-scale artificial breeding The importance is becoming increasingly prominent. How to simulate the wild environment and carry out artificial breeding of loach to en...
