Loach is quite sensitive to changes in water temperature. When the water temperature drops below 5°C, the muddy mud will climb into the mud for winter and the wintering period lasts for 2 to 5 months. In order for the muddy to survive the wintering period, the following work must be done:
First, before applying the organic fertilizer loach into the wintering pond, appropriate amount of organic fertilizer shall be sprinkled into the bottom of the pond to thicken the silt layer to provide an ideal “hotbed†for the loach overwintering. ?
Second, choose a good species to pick a healthy, disease-free loach as a species. The stocking density of wintering loach can be slightly higher than the density during the rearing period. ?
Third, pay attention to insulation wintering to do a good job of cold insulation, so that the water temperature is maintained between 2 ~ 10 °C. ?
In the paddy field's loach, the loach should be concentrated in the fish slip before wintering, and the straw can be laid in the fish slip, and the loach can infiltrate the silt in the bottom of the fish to overwinter.
