Ultrasonic Telemetry of Red Snapper, Lutjanus campechanus, at Artificial Reef Sites in the Northeast Gulf of Mexico

This species is actively sought by commercial and recreational fishers, but it is uncertain whether artificial reefs simply aggregate red snapper or actually increase their production (Bohnsack, 1989). Production of red snapper on artificial reefs is difficult to estimate without
