Due to the low temperature in winter, it is not suitable for the growth and development of loach, so during this period, the overwintering management of loach should be strengthened to ensure that the loach can safely overwinter. In the specific approach can refer to the following methods:
1. When the water temperature drops below 5-6 °C, the muddy mud will have to drill into the mud to overwinter. Natural wintering pits can properly concentrate loach species in a few ponds, and the density can be 2-3 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, which will help the muddy winter.
2. The wintering of mud, some places can use the wintering box approach. 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.
