Agricultural fish fry hatching pond device

Abstract

The invention discloses an agricultural fish fry hatching pond device, and relates to the technical field of agriculture. The problems that garbage in a pond is accumulated at the bottom in the roe hatching process, cleaning is difficult, and the hatching rate of fish fries is affected are solved. The device specifically comprises a pool body, a plurality of water inlet pipes of a three-way structure are fixedly installed at the end of the pool body, two water inlet valves are fixedly installed at the ends of the water inlet pipes, a plurality of drainage pipes of a three-way structure are fixedly installed at the other end of the pool body, and two drainage valves are fixedly installed at the ends of the drainage pipes. Roes fall into the upper portion of the hatching tray in an accelerated mode through water potential, water flows in and out of the middle layer in the hatching stage, garbage generated by big fishes above can be washed away while pond water is replaced, a valve at thelower end is opened regularly, water flows in and out downwards, garbage at the bottom of a pond is washed away, various water inlet and outlet modes can achieve the effects of changing and cleaningwater in the pond, and the hatching survival rate of fish fries is increased.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an agricultural fry hatching pond device. Background technique [0002] Fish is a good aquatic food for tonic. It is not only 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 in 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. Vitamin D, calcium and phosphorus in fish meat can effectively prevent osteoporosis. [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 t...

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
