The toxicity of nitrite also differs according to different cultured species and individuals

When death is too low, even if there is no hypoxia, it will cause fish, shrimp, and crabs to float their heads, and reduce the amount of bait, resulting in slow growth and easy disease. The main indicators that affect water quality are: pH, dissolved oxygen, nitrite, ammonia nitrogen, and hydrogen sulfide. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic.

The toxicity of nitrite also differs according to different cultured species and individuals, in order to ensure the safety of fish, shrimp, crab and other cultured species. Regular inspection can determine whether the water quality meets the requirements of the breeding species at any time. Please pay attention to our website or call us. Another function is to judge the quality of the water. In addition, algae also play a significant role in water quality. If there is too much silt, it will also have many adverse effects if it is not treated for a long time. The aerator generally relies on its own air pump to pump air into the water to achieve the purpose of increasing the oxygen content in the water.

The self-purification and buffering capacity of the pond bottom sludge is limited. The safe concentration of ammonia nitrogen varies with different cultured species. With the rapid development of the aquaculture industry, the high-density and intensive breeding model has become the mainstream breeding mode. Exceeding the concentration will cause a large number of poisoning and death of cultured species. The respiration of cultured species mainly relies on gill filaments for gas exchange in the water body. Normal marine aquaculture is Plastic Automatic Fish Feeder generally controlled between seven, and freshwater aquaculture pH is maintained between nine. The main ones are: increase oxygen consumption: organic matter Decomposition and respiration of aerobic organisms will greatly increase the oxygen consumption at the bottom of the pond.

Hydrogen sulfide is a highly toxic substance of aquatic animals. The excretion of aquaculture animals, These exogenous substances, such as uneaten feed or carcasses left by aquatic animals, have exceeded the self-purification capacity of the water body and are difficult to decompose in time. The dissolved oxygen is sufficient, the appetite is strong, the food intake is large, the growth rate of the fish body is high, and the hypoxic floating head often appears, which may cause pantang death in severe cases. The pH value is an important indicator of water quality.
