Genetic effects on tolerance to acute cold stress in red drum, Sciaenops ocellatus L. Academic Article uri icon


  • Genetic effects on cold-stress tolerance were assessed for red drum (Sciaenops ocellatus), an economically important sciaenid fish in the southern USA. Thirty-five families were generated via 'natural' spawning of multiple sets of five breeders (three dams x two sires) in individual brood tanks. Offspring from the 35 families were transferred abruptly from an acclimation temperature of 24C to 5.7C and maintained subsequently at an average temperature of 6.5C. Offspring were assigned a posteriori to individual broodfish (dam and sire) based on genotypes at nuclear-encoded microsatellites. Heritability of the survival-time probability function was estimated using a proportional hazard approach and an animal-additive model. The estimated heritability was 0.20 (95% CI: 0.07-0.40), indicating a significant genetic component to acute cold-stress tolerance in red drum. 2008 The Authors.
