Keep our native fish population robust and healthy In South Carolina, it is unlawful to intentionally release fish and other aquatic organisms into bodies of water where they were not captured. Moving fish and other aquatic organisms between water bodies is a substantial threat to our native animals and our sport fisheries. With the intention of creating new sport fisheries or changing existing fisheries by introducing non-native species, anglers can cause long-term harm to native fish communities and the sport fisheries they intend to change. Non-native fishes can out-compete native fishes for prey and habitat. Non-native fishes can also hybridize with closely related species when the eggs of one black bass become fertilized by a different member of another black bass species.
