The red drum's peculiar life history presents a challenge to assessment of the fish's status. Relatively little is known about the adult spawning population, the fish that are 4 years and older, as they live offshore where fishing for red drum is prohibited under federal law. As such, there is little information on these fish. Existing data are largely for the juveniles, ages 1 to 3, which are found in inshore waters. Fishery-dependent information is constrained by the fisheries slot limit, which ranges anywhere from 15 to 27 inches, and is supplied by multiple state surveys.
