Differences in the time of river entry of Atlantic salmon, Salmo salar L., spawning in different parts of the River North Esk
Abstract Spawning adult Atlantic salmon, Salmo salar L., were sampled in five tributaries of the River North Esk, Scotland, during the winters 1989/90 and 1990/91. The fish furthest upriver had higher sea‐ and smolt‐ages and the one‐sea‐winter fish were smaller and more coloured than those spawning...
