Water Temperature:

Water Temperature: Adapted to the water temperature of 8~31℃. 31℃, optimal growth water temperature is 15.5~26.0℃. In different water temperature environments, the activities of Portunus trituberculatus are not the same. When the water temperature is ~1.5℃, it does not feed, and some individuals freeze to death in shallow water; at 0~6℃, it does not feed, dives in the sand day and night, and is in a resting-eye state; at 8~10℃, it starts to stop feeding, and its activity is weak, and it lurks in the deep water;

At 14℃, the amount of feeding decreases, and it starts to move to the deep area, and its activity is normal; at 15~26℃, the amount of feeding is large, and its activity is normal, and its growth is fast; at 17~21℃, the peak of crossing; at 14~21℃, the beginning of the discovery of egg-holding groups; at 12~14℃, the beginning of spawning.
