Description

Out-of-season weever seedling temperature control device Technical Field The application relates to the technical field of fishery cultivation, in particular to a temperature control device for out-of-season weever seedling cultivation. Background The micropterus salmoides commonly known as micropterus salmoides belongs to the order of the shape of the micropterus salmoides, belongs to the family of the solar fishes, is an economic freshwater fish with high growth speed, delicious meat quality and high nutritive value, and keeps high demands in domestic markets, especially in northern areas, due to limited local cultivation, most of the micropterus salmoides sold in the markets are transported from the south, which not only results in high price, but also has large supply quantity fluctuation due to seasonal variation, and is difficult to meet the demands of consumers. The living water temperature range of the California weever is 1-36 ℃, the adaptability of the water temperature is similar to that of carps, but the salinity is wider, so the water temperature range is suitable for cultivation in most areas of China, however, in the north of Yangtze river, the water temperature in spring is lower, the water temperature condition required by the propagation of the California weever cannot be met, and the locally artificially propagated fries can be put in after 4 months. Even if fish fries are purchased from the south, the fish fries need to be transported in 3 months and temporarily cultivated indoors, and the fish fries cannot be put into the pond until the outdoor water temperature rises to about 15 ℃. In addition, the time that the water temperature continues to reach above 20 ℃ (the effective growth water temperature of the micropterus salmoides) is only about 3 months, resulting in the failure of the commercial specification of the offspring (typically around 3 cm) put in the pond in the current year. After overwintering, the death rate in spring is extremely high due to the infection of saprolegniasis, and the condition of cultivation loss is more common. If large-size fish seeds can be put in the spring, the fish seeds can be cultured to be on the market in 9 months, and at the moment, the market price peak period is positive, so that the culture profit of the micropterus salmoides can be remarkably improved. Through searching, the patent with the Chinese patent application number of 202210703253.X discloses a cultivation method for twice gonad maturation in one year of the weever California. The method comprises the steps of selecting the parents for temporary culture, reducing the culture water temperature in summer, increasing the culture water temperature in autumn and winter, adjusting illumination time, adjusting nutrition supplementation of the parents, calculating gonad maturation index and the like, and inducing the gonad out-of-season development and maturation of the micropterus salmoides through the measures so as to meet the serious demands of out-of-season seedling culture on the parents. However, in the method, the water temperature of the seedling raising pond is required to be reduced to 12-15 ℃ in summer at the rate of 0.5-1.5 ℃ per day, the whole process is required to be completed in 10-13 days, the operation is completely finished manually, a great deal of manpower is consumed, the parent fish is easy to generate stress reaction due to temperature change, in addition, underground well water usually contains a great deal of nitrogen and carbon dioxide, and bubble diseases can be caused by direct addition, so that the anti-season seedling raising temperature control device for weever is provided for solving the problems. Disclosure of utility model The application aims to provide a weever out-of-season seedling temperature control device so as to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a temperature regulating device grows seedlings in out-of-season of weever, includes the cistern and sets up in the pond of breeding of cistern one side, the surface mounting of cistern has the controller, be provided with on the cistern and be used for extracting the groundwater to the inside automatic retaining structure that keeps its water level of cistern and carry out oxygenation aeration's water treatment component to the groundwater of extraction, be provided with the automatic water supply structure that is used for keeping the inside temperature of pond of breeding to suit weever to grow between cistern and the pond of breeding, be provided with automatic drainage blowdown structure on the pond of breeding. In a further embodiment, the automatic water storage structure comprises a liquid level sensor arranged in the water storage tank and a submersible pump arranged on one side of the water storage tank, wherein the output end of the submersible pum
