2 During the winter, muddy plants can be used in some places. The box is 1 meter long, 0.3 meters wide and 0.2 meters high. When packing, put a small amount of soft mud in the box first, and then the layers of mud are loaded. Each layer of mud weight weighs about 2 kilograms, and after being filled, the lid is nailed and sunk into the bottom. In the second year of March, when the water temperature reaches 6°C or more, the muddy fish in the tank can be moved into the fish pond for rearing.

Answer: 1 When the water temperature drops below 5~6°C, the muddy mud will enter the mud layer and overwinter. Natural wintering pits can properly concentrate loach species in a few ponds, and the density can be 2 to 3 times higher than conventional stocking densities. Overwintering ponds should be selected for leeward sunny days and deeper ponds for better insulation. During the winter, suitable amount of pigs and cow dung can also be added to the four corners of the pond. This will not only increase the temperature of the water, but also increase the temperature of the fermentation.
