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.
Grass carp are freshwater fish that feed primarily on aquatic plants. In the 1970s, they were introduced to a number of lakes and ponds in Florida as part of an experimental effort to control aquatic weeds, particularly the exotic plant Hydrilla (Hydrilla verticulata).rass carp are freshwater fish that feed primarily on aquatic plants.
