In addition, there is potential for physiological distress if a fish swims into a localized warm area of the water. Because of water's high heat capacity, water temperatures do not change rapidly under natural conditions. Thus, fish have not evolved the ability to adapt to rapid temperature fluctuations.
Cold water carries heat away from the body 25 times faster than air of the same temperature and as a result, the body core immediately begins to lose heat to the outside environment. At first, the body tries to generate more heat by shivering, but this is not enough to offset the loss of heat to the water. Within 20 to 30 minutes, depending on water temperature, body core temperature drops to below 35Â° C (95Â° F) cognitive functioning and judgement become affected.
