animal species with photos

Ctenopharyngodon idella (Grass carp)

Animal Fish
Family: Cyprinidae
Classification: Prohibited

Grass Carp
from 9” to 29” and nearly

Carp are extremely fast-growing fish. In areas where diploid grass carp, or Asian carp species, have been introduced they out compete other species for food, and remove vegetation that provides habitat necessary for other species for reproduction. They also increase turbidity and deplete dissolved oxygen in the water.
