It's not all frozen. It's still liquid underneath.
No matter how cold it is above the water, underneath it stays a bit warmer. The ice actually protects the water underneath from the cold. And fish can survive in much colder environments than people can. People can survive, with minimal clothing, in about 50 to 100 degree weather fairly comfortably. Fish can survive in water that is below 32 degrees (0 Celcius). Water can stay liquid at colder temperatures if it has salt in it.

Hello, The sea never freezes over completely remember the sea extends into tropical latitudes where it isnt cold, and even where it does freeze it is only the top layer, there are miles of water beneath the ice... fish survive the same way they do when there is no ice.

Only the surface of an ocean freezes,and below the surface water is still there,and that water contains oxygen,and food is also present.The fish eat the food,breath the oxygen and respirate to produce energy,and these energy is then stored as fat,which keeps the fish warm.

The ice isn't that thick. They just live under it.
