Technology of Guangdong tilapia overwintering:
Guangdong tilapia is tropical fish, not resistant to low temperature, when the temperature dropped to 12 ℃ below will gradually die. Under normal circumstances, Guangdong tilapia except in a few areas of southern China can natural overwintering, other areas are required to take measures to help the winter. According to the production practice, Guangdong tilapia has several safety overwintering method
1, hot spring water in winter.
Wintering pond area should be based on the water temperature, flow rate, the terrain and the scale of production and. Wintering pond water depth of 1.5-2 meters, the amount of water and water to close, in order to keep a certain temperature and depth. If the hot water temperature is high, should the water cooled to a certain temperature and then injected into the pond in winter, this winter and winter high density. At the same time, because of high temperature, adequate water, can strengthen the parent fish rearing cultivation, promote the broodstock gonadal precocity, early seedling propagation.
2, the factory over hot water in winter.
Utilization of cooling water in some factories, directly in the cooling pool or pond in winter winter construction. Wintering pond area depends on the cooling water temperature and flow, water depth 1.5-2 meters, also can use some factory waste steam will adjust the warm pool water according to the requirements of a good tune into the pond in winter insulation in winter. This winter can adjust measures to local conditions using heat source, low cost, good effect in winter.
3, plastic for wintering ponds.
