Fish pond with circulation micro-flow water effect

Abstract

The invention is applicable to the technical field of aquaculture, and provides a fish pond with a circulation micro-flow water effect. The fish pond comprises a pond body. The cross section side of the pond body is inverted-trapezoidal, positions at the bottom of the pond keep on the same horizontal line in the depth direction, the depth of water in the pond is not lower than 1.8 meters, the gradient of each side of the pond is higher than 1:1.5, circulation through pipes are respectively arranged on opposite long sides of the fish pond, a water inlet and a water outlet are respectively formed in opposite corners of the fish pond and are provided with cement pipes or cement brick pipelines, the water outlet is higher than the water inlet, and a power pump capable of realizing the circulation micro-flow water effect is arranged at the water inlet or the water outlet. The fish pond has the advantages that the fish pond can be in a circulation micro-flow water state, so that favorable survival environments can be provided for fish fingerlings in the pond, the aquaculture cycle can be shorted, the growth of the fish fingerlings can be accelerated, the yield can be increased, a benefit can be increased, and the like.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a fish farming pond with circulating micro-flow water. Background technique [0002] With the advancement of science and technology and the needs of people's lives, fish farming in ponds has become a way to get rich. Fish ponds are generally required to be rectangular, preferably with an area of ​​3-10 acres, a water depth of 1.6-2.0 meters, no or little silt at the bottom of the pond, drainage facilities, easy drainage, fresh water quality and no pollution, and a pH value of 7- 8.5. [0003] The current aquaculture ponds are mainly based on high-density intensive intensive farming. In order to achieve the highest water utilization rate in the same pond, the stocking density of various fish species is usually extremely high, resulting in deterioration of the water body and a decrease in the growth rate of the stocked fish species. , the incidence rate increases,...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of circulating micro-flow water fish culture pond, aims to solve the problem that present culture ponds in the prior art are all based on high-density intensive intensive cultivation mode, in order to reach the highest water body utilization rate in the same pond, Usually, the stocking density of various fish species is extremely high, which leads to the deterioration of the water body, the reduction of the growth rate of the stocked fish species, the increase of the disease rate, and the reduction of the breeding effect.
