Eating habits of dace

Mud carp are omnivorous fish. four days after hatching, mud carp begin to feed on zooplankton, such as rotifers, copepods and small cladocera. After 10 days of hatching, the body length is more than 14 cm. In addition to eating zooplankton, they begin to feed on phytoplankton. After that, eat more and more phytoplankton, until about 40 days after the emergence, when the body length is more than 4 cm, they mainly eat phytoplankton. At the same time, mud carp like to lick and scrape the algae that grow on the surface of the underwater soil or rock. In addition, mud carp also ingest a small amount of zooplankton and organic debris. Mud carp can digest and use the same species of phytoplankton as silver carp and bighead carp, but can not digest those phytoplankton with thick fibrous cell walls and glue membranes. Cultured in ponds, mud carp like to eat feed such as rice bran, peanut bran, livestock manure and so on.
