Abstract
Hybrids between the Atlantic salmon and brown trout can be identifi ed on the basis of genes coding for several protein and DNA markers. Hybrids are found in all regions where the Atlantic salmon and brown trout are sympatric. The main causes of the hybridization are the sneaking of mature male parr, escape and release of cultivated fi shes, unstable river discharges, and overfi shing. In numerous experimental crosses, the survival of F1 hybrids varies from zero (a complete loss) to normal. Post-F1 hybridization sometimes results in gynogenesis, hybridogenesis and introgression. The role of hybridization in the evolution of Salmo is discussed.
