Uzbek inhabits lakes, pools, and rivers where the water is not smooth and muddy, and spawning grounds are often found in such places. There are two requirements for spawning grounds in Wuhuan: First, in the places with lush lakes, ponds, ditches, and other inshore shores, the sediment is silt; second, the shallow water area sheltered from the water. Oyster has spawning habits and needs aquatic plants. Therefore, there are waterless grasses and deep water conditions in the spawning ground, which are closely related to spawning. It is reported that in the reed silk, blackbirds lay eggs earlier, followed by black algae and poly grass clusters. Spawning depth of 20 to 100 cm is appropriate. If the water depth of the spawning site is completely submerged due to rising water or if the water depth of the spawning ground is not suitable due to dry water, the spawning period will be delayed until the appropriate water depth is restored. If the drought is too long and the spawning ground is not properly deep enough, the brooding fish will dig up the mud on the bottom of the spawning ground, dig into suitable water depth to lay eggs, and even cause no spawning. Spawning of Wuji is also related to environmental conditions such as water temperature. The spawning field can produce eggs when the water temperature is higher than 18°C. The optimum temperature for spawning is 18 to 30°C, and the optimum water temperature is 22 to 27°C. Water temperatures below 18°C ​​or above 30°C do not produce eggs. Usually spawning on sunny days without winds, spawning rarely occurs on rainy days and on days with strong winds.
