摘要
Long-term stocking of non-native Alorone saxatihs (Striped Bass) in Toledo Bend Reservoir may have had adverse effects on the integrity of the native Morone chrysops (White Bass) and M. mississipiensis (Yellow Bass) genome through introgression. We examined microsatellite genotypes for evidence of hybridization in a sample of Striped, White, and Yellow Bass but found only four potential hybrids. Despite the introduction of millions of Striped Bass over four decades, there is no evidence for either a hybrid swarm or substantial introgression. Low numbers of hybrids may be the result of poor hybrid survival, little reproduction between species, or a combination of both.
