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.
But as far as I know, most sport fish are cold blooded. Given their cold-blooded nature, fish need to move to stay within their temperature comfort zone. Generally they do not need to move too quickly, because water has a high heat capacity, so generally change in temperature happens slowly.
