An agricultural fry hatching tank device

Abstract

The invention discloses an agricultural fry hatching pond device, which relates to the field of agricultural technology; in order to solve the problem that garbage in the pond accumulates at the bottom during the hatching process of fish eggs, which causes difficulty in cleaning and affects the hatching rate of fish fry; specifically includes the pond body, The end of the pool body is fixedly equipped with a plurality of water inlet pipes with a three-way structure, and the end of the water inlet pipe is fixedly installed with two water inlet valves, and the other end of the pool body is fixedly installed with a plurality of water inlet pipes with a three-way structure. A drain pipe, and two drain valves are fixedly installed at the end of the drain pipe. In the present invention, fish roe falls to the top of the hatching tray with the help of water potential, and the middle layer enters and exits the water during the hatching stage. While replacing the pool water, the garbage generated by the big fish above can be washed away, and the valve at the lower end is opened regularly, so that The water flows in and out to wash the garbage at the bottom of the pool. Various water in and out methods can achieve the effect of changing and cleaning the water in the pool and improve the hatching survival rate of fry.

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
