Can fish and other aquatic creatures really survive in a state of suspended animation until spring? The surprising answer is yes, sometimes. It is true that some fish can spend the winter frozen in ice and come out swimming once the ice melts.

How do fish survive after being frozen?

However, colder water can hold more dissolved gas than warmer water can, so water below freezing holds the most oxygen. Then, because fish metabolism has slowed down, they are using less oxygen. Some fish even go into a state called torpor that decreases their need for oxygen even more.

How long can a fish be frozen and live?

Any frozen fish or shellfish will be safe indefinitely; however, the flavor and texture will lessen after lengthy storage. For best quality, freeze (0 °F / -17.8 °C or less) cooked fish for up to 3 months. Frozen raw fish is best used within 3 to 8 months; shellfish, 3 to 12 months.

Can fish survive being flushed?

As experts were quick to point out following the movie's release, flushed fish typically die long before they reach the ocean, going into shock upon immersion in the toilet's cold water, succumbing to the noxious chemicals found in the sewage system, or—if they make it this far—finding themselves eliminated at a water ...

Can fish survive being frozen in a lake?

What happens if my koi pond freezes?

Koi are capable of surviving through an entire winter in a frozen pond, provided their water has sufficient oxygen. Poor-quality water will not sustain koi if they are frozen on top, as they will not be able to surface in order to breathe. Survival under ice is possible for koi; many wild populations do so.
