Roe hatching device

Abstract

The invention discloses a roe hatching device and relates to the technical field of fishery. The upper surface of a box body is rotatably connected with a box cover, a water draining pipe is fixedly welded on the left side of the box body, a rotating mechanism is rotatably connected inside the box body and connected with a water-drawing pressurizing pump and a servo motor, and a heating plate is arranged at the bottom of the box body. The rotating mechanism is connected with the water-drawing pressurizing pump through a communication pipe, an auxiliary rod is fixedly welded on the outer surface of a main rod, an exhaust hole is formed in the outer surface of the auxiliary rod, the main rod is movably connected inside the rotating sleeve in a clamped manner, the inside of the box body is oxygenated through the water-drawing pressurizing pump, and nutritional liquid can be added, in this way, oxygen and nutritional substance are provided for roe hatching; the other end of the rotating mechanism is in transmission connection with the servo motor to enable the rotating mechanism to rotate in the box body to stir roes, so that reduction of roe hatching rate due to roe adhesion is prevented.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a fish egg hatching device. Background technique [0002] Nowadays, fish farming is becoming more and more large-scale, scientific and commercialized. Fish farming adopts scientific technical means from hatching to final sales. Therefore, the hatching of fry, as the first step in the entire industrial chain, is particularly important Importantly, the traditional hatching of fish eggs is in natural waters, allowing the eggs to hatch by themselves, but there are many uncontrollable factors in this kind of hatching, and the number of fry cannot be accurately obtained. [0003] Therefore, artificial hatching of fish eggs is one of the most important methods at present, but there are many factors affecting the hatching of fish eggs, such as temperature, oxygen content in water, pH value, density of fish eggs, and the nutrients needed by fry after shell breaking Substances, even light...

[0002] Nowadays, fish farming is becoming more and more large-scale, scientific and commercialized. Fish farming adopts scientific technical means from hatching to final sales. Therefore, the hatching of fry, as the first step in the entire industrial chain, is particularly important Important, the traditional hatching of fish eggs is in natural waters, allowing the eggs to hatch by themselves, but there are many uncontrollable factors in this kind of hatching, and the number of fry cannot be accurately obtained

[0003] Therefore, artificial hatching of fish eggs is one of the most important methods at present, but there are many factors affecting the hatching of fish eggs, such as temperature, oxygen content in water, pH value, density of fish eggs, and the nutrients needed by fry after shell breaking Substances, even light, can affect the hatching rate of fish eggs, the length of hatching of fish eggs and the quality of seedlings. Therefore, a device that can provide all the necessary conditions for fish egg hatching is needed to meet large-scale fish egg hatching
