Seedling culture device suitable for cynoglossus semilaevis and method

Abstract

The invention discloses a seedling culture device suitable for cynoglossus semilaevis and a method, and particularly relates to the technical field of seedling culture. The seedling culture device comprises a culture box, the upper surface of the culture box is provided with a cover plate, the back surface of the culture box is fixedly connected with the front surface of a storage box, and the upper surface of the storage box communicates with one end of a feeding pipe. According to the seedling culture device, by providing fan blades, a connecting cylinder, a magnetic plate, a coil, a cathode plate, an anode plate, a water changing box, a second rotating joint, a second gear, a second driving wheel set and a dirt suction pipe, sterilization and disinfection can be carried out on water in the water changing box, the second driving wheel set drives the dirt suction pipe to rotate at the bottom of the culture box through the second gear, and therefore the dirt suction pipe can cover the bottom of a culture pool, cleaning is carried out on the dirt in the culture pool, meanwhile, the probability that fries are possibly damaged due to clamping is reduced, it can be guaranteed that water is continuously sterilized and disinfected during water changing, the safety of the fry culture environment is guaranteed to a certain degree, and meanwhile it is guaranteed that the dirt suction process is smoothly and safely carried out.

Description

technical field [0001] The invention relates to the technical field of seedling raising, and more specifically, the invention relates to a seedling raising device and method suitable for tongue sole half smooth. Background technique [0002] Semi-smooth tongue sole belongs to Sphenomorpha, Sole suborder, Glossoleidae, Glossole genus. Commonly known as Longli and Sole rice, it is a common warm-water coastal bottom fish in China. It is distributed along the coast of China, mainly in the Bohai Sea and the Yellow Sea. It is a rare seawater fish unique to Northeast Asia. Semi-smooth tongue sole has excellent characteristics such as small activity range, low nutritional level, large individual, fast growth, etc., high economic value, and is deeply loved by people. It is an ideal breeding object. With the rapid development of half-smooth tongue sole aquaculture, some problems have emerged one after another. Due to long-term inbreeding, the growth rate and disease resistance of to...

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.
