[Frequently Asked Questions] Loach Breeding: Management Method of Loach in Autumn and Winter
[Expert answer]
Cockroaches are quite sensitive to changes in water temperature. When the water temperature drops below 15°C, their appetite diminishes and they grow slowly. When the temperature of the water drops below 6°C, the muddy mud gets into the mud 15cm deep and is in a dormant state. Whether or not the loach can safely pass through the winter is related to aquaculture benefits. The following Xiao Bian will take you to look at the muddy autumn and winter management methods:
First, timely feeding, fattening fertilizer. Loach can be eaten at temperatures above 10°C. When the water temperature is above 20°C, it is the key period for fattening and mashing, and it should be fully fed. When the water temperature is above 15°C, the muddy quail feeding is still more vigorous and the feed can not be relaxed. When the water temperature is 10～15°C, it should be fed at least once a day. . During this period, the ratio of feeding of animal feed should be increased, and a small amount of compound amino acids and vitamins should be mixed in order to increase the utilization of feed for the loach. When the water temperature is lower than 10°C and there is still muddy uplifting at noon on sunny days, a small amount of feed should be adhered to.
Second, build a greenhouse, cold and warm. When the water temperature is lower than 10°C, the growth of the loach gradually slows until it stops growing, and the artificial cold-proof and warm keeping can relatively prolong the growth period of the loach. Specifically, when the water temperature is around 15°C, bamboo sticks are inserted around the loach aquaculture ponds to form an arch scaffolding structure, and a transparent plastic film is used to set up an artificial warm shelter, which can ensure normal light and can effectively reduce heat loss and can prolong Mud growth period more than a month. Suitable for the promotion and application of ponds with small water surface.
Third, take measures to safely winter. Natural wintering open-air ponds, when the temperature drops below 10°C in November each year, the loach begins to stop feeding and gradually enters the winter dormancy period. There are two natural wintering ways for open-air pond mud. First, the dry pool is overwintering. After the mud has stopped, the pool water is allowed to dry. After the mud has entered the bottom of the pool, 15-20 cm thick straw or crop stalks are covered on the mud surface to keep the sediment wet and free of ice. Don't overcrowd the covering to prevent the mud from suffocating. When the soil is dry, the cover can be sprayed with water and wet, and no water can be sprayed on the cover. The second is deep water overwintering, that is, before the loach enters the wintering period, the pond water level is raised to about 1 meter, and the loach is drilled into the underwater soil for hibernation. Pay attention to the water level during the winter and timely replenish the water to prevent the mud from freezing due to the shallow water level. If the pool water is frozen, it is necessary to manually break the ice in case of ice-induced suffocation due to lack of oxygen.
