Problems solved by technology

[0003] Seed cultivation is an important link in the cultivation of yellow eel loach. Due to the low survival rate of eel loach seedling cultivation using the traditional seed cultivation method, the seedling cultivation of eel eel loach has become a bottleneck restricting the large-scale cultivation of eel eel loach

Embodiment Construction

[0013] 1. Selection of backup broodstock. From April to November each year, select large, plump and flawless 1-2-year-old yellow eelfish as backup broodstock for breeding.

[0014] 2. Ecological aquaculture system equipped with water treatment facilities: round ponds or square cement ponds with rounded corners are used for broodstock breeding ponds, with an area of ​​20 to 200 square meters, a water depth of 1 to 2 meters, and a stocking density of 2 to 15 fish / M 2 . In broodstock rearing ponds, the circulating water treatment system mediates and improves water quality. Through the automatic control system, the seasonal change rhythm of water temperature, salinity, and sunlight cycle is effectively regulated, so that the gonads of the backup broodstock of the yellow eelfish develop naturally under the imitation of natural environmental conditions.

[0015] 3. Broodstock breeding and nutrition strengthening: summer and autumn are the critical period of germ cell proliferation...

Abstract

Provided is selective breeding technology of yellow paramisgurnus dabryanus. The selective breeding technology comprises following steps: 1, reserving parent fish; 2, selecting reserved parent fish; 3, selecting and breeding parents; 4, breeding and sieving parent fish; 5, providing fine parent fish; 6, performing artificial reproduction; 7, breeding seedlings; 8, authenticating and sieving germplasm; 9, breeding adult fish. The selective breeding technology of yellow paramisgurnus dabryanus provides a set of operation technique process suitable to hatching of local seedlings and offers a scientific basis to the selective breeding system of yellow paramisgurnus dabryanus.

Description

technical field [0001] The invention relates to the technical field of aquatic products, in particular to the technique of breeding fine varieties of yellow eelfish. Background technique [0002] Yellow loach is a high-quality freshwater fish, which belongs to a species of loach. Compared with green loach, yellow loach has the advantages of larger size, firmer meat, and faster growth. important breeds. For quite a long period of time in the past, the culture of yellow plate loach was restricted by factors such as slow technological update, unqualified seed breeding technology, outdated breeding mode, and insufficient market development. [0003] Seed cultivation is an important link in the cultivation of yellow eel loach. Due to the low survival rate of eel loach seedling cultivation using the traditional seed cultivation method, the seedling cultivation of eel eel loach has become a bottleneck restricting the large-scale cultivation of eel eel loach . The key technology ...
