Fish and shrimp circuitous ecological circulating water aquaculture facility

Abstract

The invention discloses a fish and shrimp circuitous ecological circulating water aquaculture facility. The facility comprises a pond. One end of the pond is provided with a water treatment device. The pond is internally provided with a plurality of water separating walls. The water separating walls divide the pond into a cultivation water path formed by a plurality of flow channels. The flow channel on the middle part of the pond is internally provided with a feeding device. A floating platform is provided with an ejection device which can eject materials in a feeding plate out of a discharging base. The ejection device is provided with a scraper mechanism which can make materials on the front end of the feeding plate concentrated on the rear side of the feeding plate. The facility also comprises a feeding mechanism which continuously supplies materials to a storage vat. An objective of the invention is to provide a fish and shrimp circuitous ecological circulating water aquaculture facility, and the facility is simple in structure, effectively ensures water oxygen content and good water quality conditions, and is good in culture effect, good in bait dispersibility in feeding, wide in feeding range.

Description

technical field [0001] The invention relates to a roundabout ecological circulation aquaculture facility for fish and shrimp. Background technique [0002] Pond culture is one of the main forms of aquaculture. Since the 1970s in China, fish pond culture, shrimp and crab pond culture, and aquaculture fry pond cultivation have flourished successively in China. The aquaculture water body is about 10 billion cubic meters , Such a large scale of farming has made great contributions to the development of my country's aquatic economy. Existing aquaculture ponds are mainly rectangular in shape with a uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds that are equipped with water stirring and aeration machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very ...

AI Technical Summary

Problems solved by technology

Existing aquaculture ponds are mainly rectangular in shape with uniform water surface, and the inlet and outlet are arranged at one end of the pond or separately at both ends of the pond. Except for a very small number of aquaculture ponds equipped with water-stirring and oxygen-increasing machines, The vast majority of ponds only have obvious water flow channels near the inlet and outlet, and most of the water exchange rate in other places is very low. The corners of the pond far away from the inlet and outlet often become dead corners, the water quality in the pond is not uniform, and the local area is often hypoxic conditions, the cultured organisms cannot obtain a suitable growth environment, diseases frequently occur, the production speed is slow, and even the breeding capacity decreases, and the production efficiency is low

[0003] In addition, in order to improve the efficiency of breeding work, feeding devices are generally used when feeding feed to the farming area. Due to design defects, the current feeding devices on the market have poor dispersion of bait when feeding, and fish and shrimp need to be concentrated. eat in a small area

it's bad for feeding
