Fish fry breeding pond

Abstract

The invention provides a fish fry breeding pond, which comprises a cylindrical pond body, a water inlet pipe I, a drain pipe I, an excrement discharging pipe, an excrement collection tank, a water purification tank, an overflow pipe, a water pump I, a water outlet and an excrement outlet. The upper edge of the pond body is flush with the ground; the water inlet pipe I is arranged horizontally, oneend of the water inlet pipe I is communicated with the water purification tank through the water pump I while the other end is arranged in the inner wall of the pond body, and a 30-60-degree angle isformed between a water outlet direction of the water inlet pipe I and the tangent line of the periphery of the inner wall of the pond body; the water outlet is positioned in the middle of the bottomsurface of the pond body, and the lower end of the water outlet is connected with the drain pipe I; the middle of the bottom surface of the pond body is provided with the excrement outlet, and the excrement outlet extends out of the pond body from the lateral side along the lower portion of the pond body through the excrement discharging pipe to penetrate into the excrement collection tank; the overflow pipe is arranged in the middle of the side wall of the other side of the excrement collection tank and communicated with the water purification tank. The fish fry breeding pond has advantages that defects in the prior art are overcome, fish excrement can be cleared conveniently and quickly, and energy consumption can be reduced as far as possible while oxygen supply is improved.

Description

Technical field [0001] The invention relates to the field of fish breeding equipment, in particular to a fish fry breeding pond. Background technique [0002] In the process of artificial fish farming, the fish are excreted in the pond, and the excrement is deposited on the bottom of the pond. The prior art fish farming pond is difficult to completely clean the fish excrement, and it is usually cleaned by a thorough water change. A large amount also affects the stability of the normal growth environment of fish; and if it cannot be cleaned up in time, the excrement will pollute the pond water, increase the possibility of fish hypoxia, and affect the growth of fish in the pond. Summary of the invention [0003] The invention aims to provide a fish fry breeding pond, which overcomes the defects of the prior art, can easily and quickly clear fish excrement, improves oxygen supply and reduces energy consumption as much as possible. [0004] The technical scheme of the present invention...

Problems solved by technology

[0002] During the artificial culture of fish, the fish excrete in the pond, and the excrement is deposited at the bottom of the pond. It is difficult to completely clean the fish excrement in the fish culture ponds of the prior art. If the amount of excrement is large, it will also affect the stability of the normal growth environment of fish; if it cannot be cleaned up in time, the excrement will pollute the pool water, increase the possibility of fish hypoxia, and affect the growth of fish in the pool
