Spatial and Temporal Variation in Recovery of Hatchery-released Red Drum ( Sciaenops ocellatus ) in Stock-Enhancement of Texas Bays and Estuaries
Spatial and temporal variation in recovery of hatchery-released red drum (Sciaenops ocellatus) was assessed in nine bays and estuaries along the Texas coast. Sixteen nuclear-encoded microsatellites were used to identify a total of 167 hatchery-released fish among 4325 red drum sampled between the fa...
