High-yield fishery breeding facility adopting roundabout water circulation

Abstract

The invention discloses a high-yield fishery breeding facility adopting roundabout water circulation. The breeding facility comprises a pond, wherein a water treatment device is arranged at one end of the pond; a plurality of water dividing walls are arranged in the pond and divide the pond into breeding water channels formed by a plurality of water flow channels; a lifting suspension bridge casting mechanism extending to the center of the pond is arranged on one side of the pond and comprises a mounting seat, a suspension bridge is hinged to the mounting seat, and a traction device enabling the suspension bridge to turn over and lift is arranged on the mounting seat; an ejection device is arranged on the mounting plate; a shifting disc mechanism is arranged in a storage barrel. The high-yield fishery breeding facility adopting roundabout water circulation has the advantages of simple structure, good water quality, good breeding effect, good bait dispersity during feeding and wide casting range, and can effectively guarantee the oxygen content in water.

Description

technical field [0001] The invention relates to a circuitous water circulation high-yield fish farming facility. 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 low. The corn...

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
