Greenhouse culture device for improving growth rate according to living habits of loach

Abstract

The invention discloses a greenhouse culture device for improving the growth rate according to the living habits of loach. The greenhouse culture device includes a culture box, an intake pipe, an airflow and temperature fine-tuning device, a slide rail, an aerator, a thermometer, a drainage pipe, an automatic dredging and anti-blocking device and a culture mud layer. The culture mud layer is embedded into the inner lower end of the culture box body. The drainage pipe is welded to the lower left end of the culture box body. The automatic dredging and anti-blocking device is in interference fitwith the right end of the drainage pipe. The thermometer is connected by gluing to the upper left end of the culture box body. The aerator is welded to the inner rear end of the culture box body. Through the setting of the automatic dredging and anti-blocking device and the combination of a lower mud retarding head and a mud retarding sleeve, the adhesion and accumulation of sludge is reduced. Animpeller and a centrifugal mud scraping structure cooperate with each other to smoothly scrape down and throw out the mud under the mud retarding sleeve, so that the water in the culture pond is changed smoothly, the quality of water is ensured, and a suitable growth environment is created for loach.

Description

technical field [0001] The invention relates to an aquaculture device in a three-dimensional pond in a shed, in particular to an aquaculture device in a shed which can improve the growth rate according to the living habits of loach. Background technique [0002] With the improvement of people's living standards, people's ability to consume aquatic products has gradually increased. Aquatic products include all aquatic animals and plants, including loach, while the population of wild loach is gradually decreasing due to people's excessive fishing and environmental pollution problems. , Continued fishing can no longer meet the needs of the market, and can only rely on artificial breeding. The production speed of outdoor cultured loach is relatively slow, and the indoor three-dimensional pond culture method is often used for breeding. There are some problems in this process; 1. Due to the range of loach production temperature Between 5 degrees and 30 degrees, the most suitable t...

Problems solved by technology

[0003] For the deficiencies in the prior art, the object of the invention is to provide a cultivation device in a shed that improves the growth rate according to the living habits of loach, to solve 1, because the scope of loach production temperature is between five degrees and thirty degrees, the most suitable The temperature is between 22°C and 28°C. The summer temperature in the south often exceeds 30°C so that loach enters aestivation state and stops growing. In winter, it enters hibernation state at around zero temperature, which limits the growth of loach. 2. Because loach likes to dig holes, it must Spread a layer of sludge in the breeding pond to facilitate the growth of loaches. During the water change process of the breeding pond, the sludge in the pond will block the mud blocking plate of the outlet with the flow of water body, making it impossible to change the water in the breeding pond, resulting in Deterioration of water quality affects the normal growth of loach
