Estimates of Heritability of Larval and Early Juvenile Growth Traits in Red Drum (Sciaenops ocellatus) Academic Article uri icon


  • Eighteen to 29 families of red drum were generated via spontaneous spawning of multiple sets of three dams two sires. In 2002, offspring from spawning events were grown in separate larval ponds to a mean TL of 30.4 mm. In 2003, offspring from spawning events were individually passive integrated transponder (PIT)-tagged and grown in "common-garden" tanks from 121.9 to 166.6 mm. Offspring in both experiments were assigned to parents based on genotypes at four microsatellite loci. Heritability estimates were 0.24 0.06 (larval TL) and 0.48 0.16 (juvenile-specific growth rate in length) and indicate a significant genetic component for both traits. 2008 by The Haworth Press.
