Species: Hypophthalmichthys molitrix

Range: China and eastern Siberia

Habitat: Primarily riverine

Spawning Habitats: Egg layer, similar to striped bass.

Feeding Habits: A zoo/phytoplankton filter feeder, which feeds near the surface gulping water and passing it over its gill rakers.

Age and Growth: To 41 inches and over 100 pounds

Potential Concerns: Hypophthalmichthys molitrix is restricted due to its ability to spawn successfully in the US and potential impact on phytoplankton and zooplankton which form the base of the aquatic food chain for many fishes and animals.  Widely used in aquaculture.
