A water circulation pond culture facility

Abstract

The invention discloses a water circulation pond culture facility. The water circulation pond culture facility comprises a pond. A water treatment device is arranged at one end of the pond. Multiple water body partition walls are arranged in the pond. The pond is divided into a culture water channel formed by multiple water flow channels through the water body partition walls, and the water flow channels are sequentially communicated end to end. A water inflow pipe of the water treatment device is arranged in one end of the culture water channel, and a water outflow pipe of the water treatment device is arranged in the other end of the culture water channel. A charging device is arranged in the water flow channel in the middle of the pond and comprises a floating table. A launching gear is arranged on the floating table, and a thumbing disc mechanism enabling materials to smoothly enter a discharge port is arranged in a storage barrel. In order to overcome the defects in the prior art, the water circulation pond culture facility is provided, wherein the structure is simple, the oxygen content and good water quality status of a water body can be effectively guaranteed, the culture effect is good, bait dispersion in the feeding process is good, and the charging range is wide.

Description

technical field [0001] The invention relates to a water circulation pond cultivation 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 corners of the pond fa...

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
