Aquatic animal breeding system

Abstract

The invention relates to the field of aquatic animal breeding, and provides an aquatic animal breeding system. The aquatic animal breeding system comprises a breeding pond, a settling pond, a filter pond and a water pump. The bottom of the breeding pond is inclined from the periphery to the center. The breeding pond and the settling pond are connected through a pollution collecting pipe. The end, connected with the breeding pond, of the pollution collecting pipe is located in the center of the bottom of the breeding pond. The end, connected with the settling pond, of the pollution collecting pipe is vertically arranged. One or more pollution absorption grooves are formed in the end, connected with the breeding pond, of the pollution collecting pipe. A partition plate is arranged between the settling pond and the filter pond. The aquatic animal breeding system has the advantages that water pressure is utilized, the effect of pollution removal and separation of the breeding pond can be achieved by opening the water pump, the purpose of cleaning the bottom of the pond even in the breeding cycle can be achieved, breeding pollutant residues in the pond are reduced, the water changing frequency is reduced, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to the field of aquatic animal breeding, in particular to an aquatic animal breeding system. Background technique [0002] In aquaculture, the main sources of pollution in aquaculture ponds are residual bait, aquatic animal excrement, phytoplankton that have lost their vitality, and organic pollutants such as animal carcasses and residual limbs. The decomposition of organic pollutants in the aquaculture pond will lead to the increase of heterotrophic bacteria, ammonia nitrogen, hydrogen sulfide and other toxic and harmful substances in the aquaculture water, and the deterioration of water quality. A large number of water changes is the main method to solve this problem in current production. However, a large number of water changes waste water sources on the one hand, pollute the environment, and easily cause emergency response to aquatic animals. [0003] In aquaculture ponds rich in phytoplankton, the photosynthesis of phytopl...

AI Technical Summary

Problems solved by technology

[0005] The technical deficiencies of the shrimp pond described in "A Shrimp Breeding Pond" (Application No.: 201210471841.1): 1. The dirt was not taken away from the culture pond, and the sewage continued to decompose and release toxic and harmful substances during the culture period; 2. The system There is no filtering device in the pond, water-soluble pollutants in the aquaculture water; 3. The short-term failure of the hydrodynamic equipment (oxygenation device) in the pond will cause changes in the ecological environment of the aquaculture in the pond

4. To thoroughly clean up the breeding waste deposited at the bottom of the pond, the only way to clean the bottom is to drain the pond water, which requires a lot of waste of water resources

[0006] The technical deficiencies of the sewage system described in "Automatic Sewage System for Breeding Ponds" (Application No.: 201210338483.7): 1. The system adopts the water pressure direct discharge type, which needs to rely on replenishing new water to achieve the effect of sewage discharge, which is easy to cause aquatic animals in the pond Emergency; 2. The sewage system needs to consume a lot of water resources to achieve the sewage effect by supplementing new water

[0007] In addition, existing aquaculture systems lack techniques for resuspension of phytoplankton
