Fishpond for breeding out-of-season fry by using thermal spring water and breeding method

Abstract

The invention discloses a fishpond utilizing thermal spring water to cultivate out-of-season fries, thermal spring water pipes are arranged at the bottom in the fishpond, two ends of each thermal spring water pipe are sequentially positioned on two sides of the fishpond, each thermal spring water pipe comprises a thermal spring water inlet and a thermal spring water outlet, and a cultivation water inlet is further arranged on the side wall of the fishpond on one side of the thermal spring water inlet. And a blowdown device is also arranged in the fish pond. The breeding method comprises the steps of preparation before putting, bait organism breeding, fry selection and transportation, fry putting, daily management and fish disease prevention and treatment. According to the fishpond, the self-heating temperature of the hot spring can be transmitted into the water body of the fishpond, the breeding temperature of the water body during out-of-season breeding is kept, and residual feed and excrement in the fishpond can be effectively, conveniently and completely cleaned through the blowdown device, so that the influence of water body pollution is reduced, and the survival rate of out-of-season breeding is increased. According to the breeding method, targeted limitation is further made according to out-of-season characteristics and the like so as to be matched with the fishpond to further improve the survival rate of out-of-season breeding.

Description

technical field [0001] The invention relates to the technical field of off-season fry cultivation, in particular to a fish pond and a cultivation method for cultivating off-season fry and fry using hot spring water. Background technique [0002] Due to their slender body, poor adaptability to the environment, narrow range of food, weak active feeding ability, and easy death and attack by predators, fish fry must be carefully reared and managed in a small water body under artificial control, and cultivated to a certain size. Robust species. Seed rearing is an important part of the fish farming process. Because fry breeding is more difficult than normal fish growth, and fry breeding has higher environmental requirements than fish fry, usually the suitable breeding environment is extremely limited, resulting in a low number of fry cultivation and affecting the formation of fish fry The quantity is difficult to meet the large-scale cultivation of edible fish species, which in ...

Problems solved by technology

Because fry breeding is more difficult than normal fish growth, and fry breeding has higher environmental requirements than fish fry, usually the suitable breeding environment is extremely limited, resulting in a low number of fry cultivation and affecting the formation of fish fry It is difficult to meet the large-scale cultivation of edible fish species, which leads to the high price of formed edible fish, and also causes great constraints to the entire industry
