Testing the Ability of a Temperature‐Based Model to Predict the Growth of Age‐0 Arctic Grayling
Abstract We tested the ability of a temperature‐based growth model for European grayling (also known as grayling) Thymallus thymallus to predict the growth rate of age‐0 Arctic grayling T. arcticus in two reaches of a small Alaskan stream. We compared observed and predicted lengths at weekly interva...
