Sterile/triploid grass carp will be stocked into Lake Billy Shaw for biological control of dense aquatic vegetation (milfoil) that is degrading and displacing game fish and waterfowl habitat. An average of six fish per acre will be stocked following guidance in scientific literature for partial control of problem plants without misbalancing the ecology of the lake.
