Crayfish breeding, hatching and collecting device

Abstract

The invention discloses a crayfish breeding, hatching and collecting device. The device comprises a culture pond, a circulating water tank and a sewage tank, the outer side of a bottom plate of the culture pond is arranged in the circulating water tank through supporting legs, the sewage tank is arranged on one side of the circulating water tank, a circulating water pump is arranged on the other side of the circulating water tank, one end of the circulating water pump is in communication with the culture pond through a circulating water inlet pipe, and the other end of the circulating water pump is in communication with the circulating water tank through the circulating water inlet pipe. According to the crayfish breeding, hatching and collecting device, a cleaning brush is used for cleaning the bottom of the culture pond, residues of impurities at the bottom of the culture pond are reduced, and the culture pond is convenient to clean; meanwhile, a sewage outlet valve is opened, impurities flow out from a sewage outlet pipe and enter the sewage tank, the circulating water pump can enable water in the culture pond and the circulating water tank to circulate, the activity of the water is kept, and therefore, the activity of juvenile crayfish is improved; and the crayfish breeding, hatching and collecting device is reasonable in structure, convenient to use and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a crayfish breeding, hatching and collecting device. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farming and fence farming. High-density intensive farming uses methods such as running wa...

Problems solved by technology

[0003] At any time, crayfish are becoming more and more popular in the market, and the breeding of crayfish is increasing day by day. The key to breeding is crayfish seedlings. Traditional seedlings are hatched in large hatching sites, and they are removed when the seedlings grow to a certain size. Nursery ponds, but the large area of ​​seedlings results in a low survival rate of hatchlings, the young shrimps are easily swallowed by the seedlings, and the struggle between the young shrimps will also cause the death of the young shrimps, and large-scale seedlings have a negative impact on water quality, water temperature and water content. Difficult to control oxygen
