Stream temperature variability - Ashley Steel

Growth and survival of fish in streams is regulated in large part by water temperature. When the water is warm, the fish’s metabolic rates speed up; when the water is cool, the fish’s metabolism slows down. These changes affect how much the fish needs to eat, how quickly it can grow, and how fast it might transition from one lifestage to another, say, from egg to alevin to free-swimming fry.
