What should I do if I encounter noctilucent insects in the process of winter shed shrimp farming?

In the winter shed breeding pond visit, the water luminescence is also a relatively common phenomenon, if it is found before the seedlings are found to have this phenomenon, it is okay, directly discharge the pond water, re-enter the water, disinfection, fertilizer pond can generally solve this problem. However, in most cases, there is a phenomenon of water or even shrimp body glowing in the process of shrimp farming, and many customers have reported that the treatment effect is not ideal. Today I will give you a recipe that has been verified by our technicians for many years, and don't miss it if you encounter it.

1. Two universally recognized factors that cause luminescence

There are two known causes of luminescence in water. One is what people often call a luminous insect, which belongs to a type of luminescent dinoflagellatesAt night, luminescent dinoflagellates are concentrated in the upper layers of the water body, and we can observe the fluorescence phenomenon when the water is shaking, and its distinctive feature is that the fluorescence is transformed into a dotted form.

When there is a large number of luminescent algae, the neurotoxin secreted by it has a strong toxic effect on shrimp, and secondly, it can attach itself to the gill filaments of shrimp to hinder the normal respiration of shrimp, and at the same time, luminescent algae will consume a large amount of dissolved oxygen, affecting the normal physiological activities of shrimp, and shrimp often have the problem of reducing feed and eating slowly.

There are generally two reasons for the abundance of luminescent dinoflagellates:

One. It is a small amount of dinoflagellate that exists in the endogenous water body, and when the water environment is suitable for its reproduction (too much organic matter, eutrophication of the water body), it will multiply in large quantities and cause the water body to glow, and the probability of ammonia nitrogen and sub-salt appearing in the water body will increase;

Two. It is the luminescent dinoflagellates present in the exogenous water that enter the pond through the inlet water, so it is necessary to pay attention to whether the outside inlet ditch also emits light when entering the water.

The other is bacterial luminescence, which is caused by Vibrio luminescentIt is characterized by the fluorescence of the whole sheet, and the body of the shrimp also appears to fluoresce after infection. Shrimp infected with Vibrio luminescent will float downwind of the water surface, slow to react, and often see symptoms such as broken whiskers, blackened fractures, material reduction, and successive deaths during salvage observation.

2. The principle of processing

The appearance of water luminescence generally belongs to two reasons for concurrency, and the singleness to deal with it in many cases can not achieve the expected effect, of course, there will be differences in the selection of products, but the majority of breeding friends should pay attention to:

The harm of "noctilucent insects": living organisms can secrete toxins, and after death, more toxins are released, which are harmful to breeding from birth to death. The treatment of water luminescence is mainly to inhibit and condition, and it is not suitable to sanitize, otherwise the consequences are very serious.

It is necessary to treat it appropriately with chemicals, and sometimes to improve the water quality to avoid the presence of a large number of bacteria in it.

When encountering moonlight insects, we must first carry out prevention and control, if the situation is relatively mild, water disinfection can be carried out, and if the condition is more serious, it can be combined with antibacterial drugs for insecticide.

If you need to drain water on time, you can use some dolomite powder to solve it, and you can use some chemicals.
