Further Evidence of Size Gradients of Arctic Grayling (Thymallus arcticus) Along Stream Length
Previous work in Alaska indicates that the distribution of Arctic grayling (Thymallus arcticus) along streams is influenced by fish size. Larger fish are usually found in the upstream reaches, and the mean size gradually decreases further downstream, closer to the stream mouth. One of the hypotheses...
