A Genetic Assessment of a Red Drum, Sciaenops ocellatus , Stock Enhancement Program
Abstract The South Carolina Department of Natural Resources began a stock enhancement research program for red drum, Sciaenops ocellatus , as a possible management strategy for augmenting the availability of juveniles for recreational harvest in South Carolina estuaries. Between 1999 and 2011, appro...
