What are the advantages of using microporous tubes to increase oxygen at the bottom of crab ponds?

Microporous underwater aeration and oxygenation technology has effectively solved the problem of oxygenation in high-density, factory-based, and intensive aquaculture. It has especially played an important role in the healthy cultivation of river crabs and has gradually become popular. The welcome and favor of farmers.

(1) The importance of water dissolved oxygen in river crab breeding

The level of dissolved oxygen in the breeding water environment is an important indicator of water quality. In water bodies with high dissolved oxygen, river crabs and other species raised in cages eat vigorously, have high survival rates, low feed coefficients, less disease, and fast growth; low dissolved oxygen leads to reduced appetite, slow growth, and poor resistance of the cultured objects. The pay is high. Dissolved oxygen not only allows the breeding objects to breathe, but also promotes material circulation in the pond water by oxidizing and decomposing organic matter in the pond. Ammonia, a toxic biological metabolite, is quickly absorbed by phytoplankton as a nutrient salt, and toxic nitrite is quickly converted into non-toxic nitrate, which will not accumulate to a toxic level. On the contrary, in the case of low dissolved oxygen or anoxia, the material circulation process in the water is damaged, and the conversion of ammonia comes to a standstill. As a result, toxic substances such as ammonia accumulate in the pool water, forming toxic ammonia nitrogen and nitrite. Salt. It is even possible to produce hydrogen sulfide, which is more harmful to cultured objects.

(2) The main advantages of microporous aeration bottom layer oxygenation

① High oxygenation efficiency: Because the bubbles generated from the microporous tube are small and dense, the floating flow rate is low, and the The water contact time is long, so the oxygen conduction efficiency is extremely high.

② Promote a virtuous cycle of pond ecology: Microporous pipe oxygenation adds oxygen from the bottom of the pond, thus effectively preventing the formation of an anaerobic layer at the bottom of the pond, and the decomposition products of underwater microorganisms can be quickly transformed.

③Energy saving: The power per acre of the microporous pipe aeration facility is only 1/3 of the traditional aerator, so the energy saving effect is significant.

④Reducing diseases: Due to the improvement of the breeding water environment, diseases caused by poor water quality have been greatly reduced.

⑤Safety: The microporous pipe oxygenation host works on the shore, so it is not easy to leak electricity; it will not cause potential harm to people, fish, shrimps, and crabs, and it will not bring noise to the water body, which is harmful to the water body. Fish, shrimp, crabs cause disturbance.
