According to recommendations, during cold weather, absolutely do not pull nets to check, do not harvest by thinning to limit scratches to reduce the possibility of disease and damage to farmed aquatic products.

Farmers need to maintain the water level in the pond to stabilize the water temperature, ensuring a depth of 1.5 - 2m; make a frame and cover the pond surface with light-colored plastic or spread water hyacinth on the pond surface from 1/2 - 2/3 of the pond surface area to block the wind; move the cage to a place with less wind, or deepen the cage 1.8 - 2.0m.

Farmers must feed their aquatic animals adequately, use high-quality feed, appropriate rations and supplement vitamins to increase resistance.
