A kind of seedling raising device and method suitable for semi-smooth tongue sole

Abstract

The invention discloses a seedling raising device and method suitable for the semi-smooth tongue sole, and specifically relates to the technical field of seedling raising, including an incubator, the upper surface of the incubator is provided with a cover plate, and the back of the incubator is fixed to the front of the storage box connected, the upper surface of the storage box is communicated with one end of the feeding pipe. In the present invention, by setting fan blades, connecting cylinders, magnetic plates, coils, cathode plates, anode plates, water changing tanks, second rotary joints, second gears, second driving wheel sets and sewage suction pipes, the water in the water changing tanks can be changed. Sterilization and disinfection, the second drive wheel group drives the sewage suction pipe to rotate at the bottom of the incubator through the second gear, so that the sewage suction pipe can cover the bottom of the cultivation tank, clean the dirt in the cultivation tank, and reduce the possibility of fry being caught. The probability of damage occurs, so that the device can ensure that the water is continuously sterilized and disinfected when the water is changed, to a certain extent, to ensure the safety of the fry cultivation environment, and to ensure the smooth and safe process of the sewage suction process.

Description

technical field [0001] The present invention relates to the technical field of seedling raising, and more particularly, the present invention relates to a seedling raising device and method suitable for tongue sole semi-smooth. Background technique [0002] Semi-smooth tongue sole belongs to the order Butterfly, Sole suborder, tongue sole family, tongue sole genus. Commonly known as Longli and sole rice, it is a common warm-water near-bottom layer fish in China. It is distributed along the coast of China, mainly in the waters of the Bohai Sea and the Yellow Sea. It is a rare marine fish unique to Northeast Asia. The semi-smooth tongue sole has excellent traits such as small activity range, low nutritional level, large individual, and fast growth. It has high economic value and is deeply loved by people. It is an ideal breeding target. With the rapid development of the semi-smooth tongue sole breeding industry, some problems have appeared one after another. Due to long-term...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seedling raising device and method suitable for tongue sole semismooth. In addition, after the eggs of semi-smooth tongue sole hatch, the fry start to swim, and they are evenly distributed in the breeding tank. Now when feeding the fry, most of the food is concentrated and not uniform enough. At the same time, the fry's own resistance is poor, so It is necessary to ensure that there are fewer bacteria and viruses in the cultivation tank. At the same time, when changing the water in the cultivation tank, the water flow in the drainage area may be too fast, causing the fish fry to be impacted by the water flow on the surface of the filter, causing injuries.
