Agricultural fry hatching pond device

Abstract

The invention discloses an agricultural fry hatching pond device, and relates to the technical field of agriculture. In order to solve the problems that garbage in a pond is accumulated at the bottomin the fish egg hatching process, cleaning is difficult, and the hatching rate of fries is affected, the agricultural fry hatching pond device specifically comprises a pond body, a plurality of waterinlet pipes of three-way structures are fixedly mounted at the end parts of the pond body, two water inlet valves are fixedly mounted at the end parts of each water inlet pipe, a plurality of water discharge pipes of three-way structures are fixedly mounted at the other end of the pond body, and two water discharge valves are fixedly mounted at the end parts of each water discharge pipe. Accordingto the agricultural fry hatching pond device, the fish eggs fall into the upper portion of a hatching disc in an accelerated manner by means of water potential, middle layer water inlet and outlet are carried out in the hatching stage, garbage generated by big fishes on the upper portion can be flushed away while pond water is replaced, the valves at the lower ends are opened regularly, and therefore water flow are subjected to bottom inlet and bottom outlet, and the garbage at the pond bottom is flushed; and multiple water inlet and outlet manners can achieve the effects of changing water inthe pond and cleaning the pond, and the hatching survival rate of the fries is increased.

Description

Technical field[0001]The invention relates to the technical field of agriculture, in particular to an agricultural fish fry hatching pond device.Background technique[0002]Fish is a good aquatic food for tonic, not only tastes delicious, but also has high nutritional value. Its protein content is twice that of pork, and it is a high-quality protein with a high absorption rate by the human body. Fish is rich in thiamine, riboflavin, niacin, vitamin D and a certain amount of calcium, phosphorus, iron and other minerals. Although the fat content in fish is low, the fatty acids in it have been proven to have the effects of lowering blood sugar, protecting the heart and preventing cancer. The vitamin D, calcium and phosphorus in fish can effectively prevent osteoporosis.[0003]With the rapid development of the economy, large-scale fish farming has developed rapidly, and there is an increasing demand for fish fry. At present, many fishermen use separate hatching tanks to incubate fish eggs ...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of large-scale fish breeding with the economic development, the demand for fish fry is also increasing. At present, many fishermen use hatching tanks separated from the top and bottom to hatch fish eggs to avoid fish eggs and fry being killed by big fish. Swallowing causes production reduction, but the existing upper and lower layered hatching tanks have a simple structure, and garbage in the tank accumulates at the bottom during the egg hatching process, making it difficult to clean up and affecting the hatching rate of fry
