Tilapia is delicious in flesh and has a delicate meat quality. Regardless of whether it is braised or steamed or grilled at the night market, it has a good taste. The strong demand has led to a large increase in tilapia farmers and certain economic benefits. However, cold currents have been used and the temperature has plummeted. Tilapia without precautionary measures has caused a large area of ​​death, causing losses to farmers. Here are some considerations for wintering of tilapia and some references for farmers.
Deepen the body of water
During the winter, deepen the water body as much as possible so that the water depth is more than 3 meters. The water body is deep and bulky. When it encounters a cold wave, the water temperature drops slowly. The depth of the water body, the ground floor has a geothermal effect, the water temperature is higher.
Wind wall
For fish ponds that are not sheltered from wind, a wind wall can make up for its defects. The wind wall stands at the north end, and its height is about 3 meters. The role of the wind wall is to prevent the north wind from stirring water, avoiding convection from above and below the water, and slowing down the speed of water temperature drop.
Build insulation shed
The area of ​​the shed can be large or small, covered by a full pond, or covered by 1/4-1/2 of the fish pond. The shed is made of bamboo or iron brackets to form “people†shaped or arched scaffolds, and the roof is covered. Plastic film can be.
Stacked combustibles
When the cold wave arrives, it is effective to ignite the combustibles such as straw, turf, and leaves at night to smoke, and to form thick smoke on the pond to melt the frost.
When conditions permit, a variety of overwintering measures can be used together to make tilapia winter safer. If the temperature is extremely low and the duration is long, any wintering measures will not guarantee the safe winter of tilapia, and frozen fish will be unavoidable. Decisions should be made decisively, and tilapia should be placed on the market in order to reduce losses.
