feeding habits
The naked carp in Qinghai Lake is a broad-spectrum omnivorous fish, which mainly feeds on algae and zooplankton. Adult fish often devour decaying plant debris, aquatic insects and fish. During its growth and development, its feeding habits can be divided into three different stages: the first stage mainly feeds on small zooplankton, and the second stage mainly feeds on large zooplankton.
In the third stage (that is, the rest stage), almost all biological foods in the water body appear in the digestive tract of the fish, which is suitable for the lack of bait in Qinghai Lake. During migration and spawning, its food intake is greatly reduced, and even it stops eating for a short time.
