what temperature of water do trout need to survive
Warmer water contains less oxygen than colder water. As temperature rises and dissolved oxygen decreases, fish begin to experience stress. These stresses begin to set in well before the water temperature reaches lethal limits. For example, rainbow trout are said to be able to survive in temperatures up to and exceeding 77Â°F (24Â°C), but stop growing at 73Â°F (23Â° C).
