I was watching the news this morning and the ocean temperature is 39, how can a fish live through the cold weather in water I know they are cold blooded but how does it work?

Fish metabolism is tied to the temperature of the surrounding water. Warmer the water, the higher the biological demand. Cooler the water the lower. Therefore in winter, fish a less active and feed less. In lakes that freeze over at the surface, fish may not feed all winter.
Fish are not cold blooded. Their blood temp is similar to the surrounding water: Ectothermic, body temperature depends primarily on absorption of heat energy from the environment (e.g., reptiles, amphibians, most fish, insects).

water is different from air.water gets cold so later and looses temperature very late.and when the weather gets very cold the surface of the oceans and seas turn into ice and prevent the deep waters to turn into ice and keeps warmth in dept.
