Plants that live in streams are also referred to as aquatic plants. These plants have adapted to live in water or fully saturated soil. Most aquatic plants are perennials that reproduce by using their flowering parts, also called angiosperms. The leaves of aquatic plants tends to be large and flat to maximize the suns rays.
Controlling aquatic vegetation with grass carp is one of the options available to pond owners with aquatic plant problems. In many situations, the use of grass carp is an economical, long lasting, and effective option.However, grass carp are not appropriate for every pond with abundant aquatic plants.rass carp should never be stocked into a pond where there is a substantial risk of escape. Grass carp live in rivers in their natural environment so they actively search for moving water. They can escape through an unprotected spillway with as little as 3 inches of water flow.
