Genetic Identification of Hatchery‐Released Red Drum in Texas Bays and Estuaries
Abstract The stock enhancement program for red drum Sciaenops ocellatus in Texas annually releases from 25 to 30 million fingerlings into Texas bays and estuaries and represents one of the largest such programs for marine fishes worldwide. We used 16 nuclear‐encoded microsatellites and a 370‐base‐pa...
