Production of spotted fish with artificial breeding

Tuyen Quang Fisheries Sub-department said that it is implementing the project "Applying advanced technology to produce spotted fish fingerling with artificial reproduction".

>>>Production, successfully cultured commercial zebrafish

The project aims to diversify sources of fingerlings, especially those with high economic value, contributing to income generation and job creation for ethnic minority people living near the river basins.

Mr. Dang Xuan Canh, Officer of the Technical Department of Tuyen Quang Fisheries Department and also the Project Manager, said that artificial breeding technology of the Dot fish is a new technology, more complicated than the production technology. previous fish production.

Fish is a fish with high economic value.

The technology is applied many new technical measures in artificial reproduction such as creating flow, artificial rain spraying combined with appropriate care management regime to improve the maturity rate of broodstock compared to self. Of course.

By the method of male fish surgery, a small crushed gland is used for artificial insemination. This technology has overcome the problem of difficult clawing when artificial insemination in catfish species is due to the many nodules.

The project implementation time is until the end of 2012 on an area of ​​3,000m ² , with a total capital of nearly 570 million dong. In particular, over 430 million VND from the scientific budget, over 130 million VND from other sources.

The successful implementation of the project will diversify the variety of fingerlings, providing about 10,000 spotted fishes and 15,000 fingerlings of size 6-8cm to the market.

Spotted fish is a highly valuable commercial catfish, which is in danger of extinction. The market demand is very high but the source of natural fish is in scarcity. Tuyen Quang province has nearly 12,000 hectares of water surface capable of aquaculture, including 8,600ha of hydropower and irrigation reservoirs, 2,000ha of ponds and lakes, this is a favorable condition for the development of specialty fish species. High economic value.
