[0002] Fish breeding stations in fishways located in high-altitude and cold regions generally draw water from natural rivers. In winter, the water temperature in natural rivers is relatively low, which will lead to reduced feeding efficiency of broodstock and insufficient nutrition, which can easily cause stunted gonadal development of broodstock and affect the breeding effect in the following year. At the same time, the activity frequency of broodstock decreases in low-temperature breeding water, and frostbite is more likely to occur on the body surface, leading to water mold infection and increasing the probability of death. Since fish breeding stations usually raise and breed rare indigenous fish, broodstock are generally obtained from natural conditions and are extremely precious; therefore, the overwintering of broodstock has become one of the key issues of concern to fish breeding stations.
