A Detailed Guide to Practical Overwintering Techniques for Tilapia in Simple Plastic Greenhouses

Build a simple greenhouse to raise the water temperature in part of the pond. With low investment and easily sourced materials, it can ensure that tilapia and other fish overwinter safely in southern regions.
The main contents of the simple greenhouse overwintering technique for tilapia:
1. Construction of windbreak sheds: On the west and north sides of the pond, set up windbreak sheds. Build frames with moso bamboo or miscellaneous wood, erect them on the west and north sides of the pond, with a frame height of 3 m, then make rectangular straw mats from rice straw or sugarcane leaves and tie them to the bamboo frames to block the attack of cold wind and prevent the water temperature from dropping sharply.
2. Greenhouse film covering: Lay bamboo frames horizontally across the water surface of the fish pond, cover them with plastic film about 0.5 m above the pond water surface, covering about 1/2-2/3 of the pond area, and then cover the film with a layer of loose netting to prevent strong winds from damaging the film.
