Loach has gill respiration and intestinal respiration

The third is the jet aerator: its structure is simple, it can form water flow, stir the water body, can make the water body aerobic slowly, not damage the fish body, suitable for use in the fry pond. There are more than 90 varieties of products. Because they believe that loach will not be hypoxic and tenacious, it will not consider it. It is currently the most used aerator. The second is a waterwheel type aerator: it has a good aeration and promotes the effect of water flow, suitable for ponds with deep silt.

To The company mainly produces and operates brand environmental protection equipment, vortex type medium pressure air pump, Yuting brand medium pressure air pump, and fishing equipment. However, with environmental pollution, pesticide erosion and man-made overfishing, wild loach is becoming automatic fish feeder less and less. According to different ponds and different water depths, we will introduce several aerators suitable for different water bodies. The dissolved oxygen in the water body of the aquaculture pond is maintained at 4mg/l-5mg/l, and the fish in the pond can grow normally.

Oxygenate.ufeffGenerally speaking, loach is not hypoxic, because loach has gill respiration and intestinal respiration. Even if the water is drained, the loach can survive for a period of time in the absence of water, because the loach can also pass through the body surface. Long-term and continuous hypoxia will inevitably affect the growth of the loach and increase the incidence of the loach. The fifth is the aeration pump: because of its light weight, easy operation and single aeration function, it is generally suitable for use in aquaculture ponds or greenhouses with a water depth of less than 1 meter and an area of less than 1 mu. Artificial breeding of loach has become a trend.

However, the loach living in low-dissolved oxygen water for a long time will not only restrict growth, but also affect various physiological activities, which will eventually lead to an increase in the feed coefficient and affect the economic benefits of breeding. Farmers can choose according to their actual conditions: One is the impeller type aerator: it has the comprehensive effects of aeration, water stirring, and gas explosion. Possibility. However, the operation noise is relatively large, and it is generally used in large-area ponds with a water depth of more than 1 meter. With more than 530 specifications, nearly 2 million units of vortex air pumps have been applied and implemented since production. The fourth is the water jet aerator: it has a good oxygenation function, which can quickly increase the dissolved oxygen content of the surface water body in a short time, and it also has an artistic appreciation effect, which is suitable for breeding in tourist areas.

It can be seen that even the loach, which is extremely resistant to hypoxia, caot do without sufficient oxygen during the growth process. In order to create greater economic benefits in a certain area of pond, farmers tend to cultivate loach with high density. The skin breathes, so it is generally believed that loach is not hypoxic. Generally, the dissolved oxygen of the fish will be as low as 2mg/l before it will float, and the loach will be lower. In a certain area, the high density of the loach itself, the long-term rainy weather, and the fish medicine splashed by regular water disinfection will cause the hypoxia of the breeding loach pond
