Description

Oxygenation blowdown breed pond suitable for crayfish

Technical Field

The utility model relates to the technical field of crayfish breeding equipment, in particular to an oxygen increasing and pollution discharging breeding pond suitable for crayfish.

Background

Crayfish is an aquatic animal of the family crayfish, decapod order crustacean, also known as procambarus clarkii, crayfish and freshwater crayfish. It is shaped like shrimp and hard in shell. It belongs to freshwater economic shrimps and is popular with people because of delicious meat taste. Due to the omnivorous property, the fast growth speed and the strong adaptability, the method forms an absolute competitive advantage in the local ecological environment. The feeding range of the lobster feed comprises aquatic weeds, algae, aquatic insects, animal carcasses and the like, and the phenomenon that adult lobsters disturb and kill juvenile lobsters often occurs.

In the crayfish breeding process, a large amount of excrement can be accumulated at the bottom of the pond, and the water in the breeding pond is gradually anoxic, so that the breeding pond needs to be oxygenated. The direct use of the oxygen increasing equipment for increasing oxygen can cause the suspension of excrement at the bottom of the pool, so that the water body is turbid, and the growth and inhabitation of crayfish are influenced; therefore, a cultivation device which can avoid killing the lobsters and can increase oxygen and remove excrement is needed.
