Maintaining the environmental well being of Lake Gaston

Grass carp (Ctenopharyngodon idellus) is a large plant eating fish with a feeding preference for Hydrilla. At approximately 20 fish per vegetated acre, they have been shown to eliminate Hydrilla. When stocked in lakes and ponds, however, grass carp will eat veraciously and have been known to eliminate all green plants. In 1995, approximately 6.5 grass carp per infested acre were stocked into Lake Gaston by the Lake Gaston Weed Control Council. 5,000 were added in 1999. No restocking was done until 2003. We were permitted to add 18 per infested acre in 2015 for a total of 25,392 grass carp. We are requesting the maximum allowed for loss to attrition of 40% or 10,157 this year.
