| Abstract: | Between-population gene flow was estimated in neighbouring freshwater and anadromous Salmo trutta populations from Asturias, Northern Spain. Populations from the same drainage showed a high mean level of gene flow. Gene flow was also found between populations from different drainages and was negatively related to the distance between river mouths. The strength of the homing orientation of migratory individuals (sea trout) is discussed. |
