Problems solved by technology

[0003] At present, the artificial breeding of loach is becoming more and more widespread. Although the artificial breeding of loach meets the increasing market demand to a large extent, the per unit yield benefit of most farmers is not high. In addition to the problems of breeding technology, loach seedlings Improper selection is also the main factor affecting the efficiency of adult loach breeding
The loach seedlings selected by most loach farmers are mainly purchased from the market. The quality of these purchased loach seedlings is uneven, and there are even many low-quality seedlings mixed in, which seriously affects the efficiency of loach breeding.

Embodiment

[0017] The specific cultivation method is as follows:

[0018] a) Prenatal cultivation of parental loach. Prenatal cultivation of parental loach includes: selecting parental loach, stocking parental loach, and feeding and cultivating feed. Among them, the selected male and female parent loach come from different regions in order to obtain hybrid advantage. These parent loach are all over 3 years old and have a strong physique, no disease and no injury; Individuals with large body and full abdomen; for male loach, choose individuals with a body length of 10cm, a weight of more than 15g, lively, healthy and fast swimming. After the loach is selected, press 1000kg / 667m 2 The stocking density is put into a special pond for cultivation to promote the development of its gonads, so as to meet the requirements of artificial reproduction. The feed was fed with artificial compound feed with a protein content of 40% and added vitamin E. The added amount of vitamin E accounted for 0.01%...

Abstract

The invention provides a high-yield breeding method for young breeding loaches. The cultivation method includes the step a of antenatal breeding of parent loaches, the step b of artificial spawning for young breeding loach breeding, the step c of before-stocking preparation and stocking of young loaches, and the step d of young loach breeding management. The invention discloses the high-yield breeding method for young breeding loaches. According to the breeding method, high yield of young breeding loaches is achieved through the combination of indoor artificial young loach spawning and outdoor pond breeding larva breeding, high economic benefits are achieved, and high-quality larvae are provided for loach breeding.

Description

technical field [0001] The invention relates to a method for cultivating fish fingerlings, in particular to a method for cultivating high-yield loach seedlings, and belongs to the technical field of aquaculture. Background technique [0002] Loach is a small omnivorous bottom-dwelling freshwater fish. Although its individual is small, it has strong vitality and is widely distributed in ponds, reservoirs, rice fields, river ditches, etc. Loach meat is tender, delicious and nutritious. The edible part has high protein content and low fat content. Loach has the effects of nourishing and strengthening yang, nourishing the middle and stopping diarrhea. It is known as ginseng in water and is favored by consumers at home and abroad. In recent years, with the increasing domestic and foreign market demand for loach, the fishing intensity has continued to increase, the wild catch has decreased year by year, and natural resources have declined sharply. [0003] At present, the artifi...
