Small shedShrimpIt belongs to the small water body, semi closed, high oxygen, high density breeding mode.In the process of breeding, with the increase of feeding,CauseAccumulation of bottom residual bait, dead algae, feces, etc.. At the same time,Ammonia nitrogen, nitrite these common indicators tendalso easyExceeding the standard, this is also the characteristic of small shed.

In order to stabilize the water quality index within a reasonable range,FromTo promote high yield, we should pay attentionWhichWhere's the place?

 

Ensure sufficient dissolved oxygen

Since small shed shrimps have always been farmed in plastic sheds, when the weather is bad, such as cloudy and rainy days, cooling weather, etc., the door of the shed should be closed to make the exchange with the bad climate of nature as small as possible,Easily leadlow dissolved oxygen,Causing a lack of oxygen.

In this case,Can be usedZhixuan high-speed centrifugal fanIncrease bottom oxygen, andConfiguration of gas stone oxygen or nano oxygen.General24Hours should be openEquipment,Ensure sufficient dissolved oxygen,The purpose is to stir the water body, so that the upper and lower water body to produce convection, the surface and upper saturated oxygen to the bottom, while the bottom or lower hypoxia or hypoxia water body to the upper layer, and the inorganic salt to the upper layer, for the upper phytoplankton to provide nutrition, maintain the ecological balance of the water body.

 

Regular chemical bottom modification

Generally, high-efficiency products are used for one week, and now potassium persulfate is the most.

 

Regular detoxification

The air in the shed has poor mobility, weak water exchange capacity, and toxic and harmful substances in the water body are difficult to overflow and volatilize. Over time, it will also cause the water body to deteriorate, so it is necessary to detoxify and detoxify regularly.

 

Supplemental Algae Nutrients

According to the water quality, the appropriate amount of nutrients can be added to the algae.

 

 

stable bacterial phase

Timely and appropriate amount of beneficial bacteria to decompose macromolecular organic matter and small molecular organic matter in water body, balance the bacteria phase and algae phase in water body, and stabilize water quality.

 

Splash fungus regularly

 

Focus on the prevention and control of vibrio, it is recommended to prevent once a week; control of harmful substances such as nitrite and hydrogen sulfide, combined with regular and irregular use, it is recommended to use biological agents to control; protect the intestinal health of shrimp, improve the absorption and utilization of nutrients in the intestine, inhibit the discharge of ammonia nitrogen, so as to improve water quality.

AppropriateDrain and change water

Because the water body of small shed culture is small and shallow, the water temperature often exceeds the comfortable temperature of shrimp. At this time, it is necessary to take measures to cool down in the shed, and changing water is a simple and effective method.

 

 

In short, a variety of technologies need to be integrated in order to stabilize the water in the middle and late stages and achieve the goal of successful breeding and high yield.
