Do fish hibernate in ice?
Iced-in fish don't hibernate , but they do slow way, way down. Fish are ecotherms. Unlike us warm-blooded creatures, their body temperature changes depending on their environment. Reducing their temperature and activity level means they don't need as much food or oxygen.
What happens to fish when a lake freezes?
In shallow lakes that freeze almost to the bottom, fish kills can happen when there is not enough oxygen left in the water. When ice forms, it seals the water off from exchanging oxygen with the air and also blocks out light that helps plants and phytoplankton grow to produce oxygen in the water.
