Frozen Fish Survive!

I think they may have found a hole under a rock that didn't freeze and stayed in there. Still amazing!
 
No way the pond froze solid. Serious scientists once thought that the Alaska Blackfish, Dallia pectoralis was capable of having its tissue frozen and thawed without killing it. They don't anymore. The only critter of any size that I'm aware of that can actually survive having its tissue frozen and thawed is a cricket from New Zealand.
 
It still may be possible. You never know...

You will find that most times in life you actually do know, if you're willing to put in the work necessary to find out. In this particular case I assure you that I have put in that work.
 
Still, I have had fish laying on the ice for hours, stiff as a board, exposed to the dry cold air and they still started swimming after sitting in a tub of water. Were they frozen solid? Well they were frozen enough that they were stiff as heck. They most surely suffered tissue damage and would not have fully recovered yet they did still thaw out and swim around. That much I do know.
 
This one time...in band camp....i fell in my grandma's pond....froze solid....


Grats on your fish surviving chips!
 
agreed with all the above..including the ones who said "not frozen ALL the way down." As slow as their metabolism gets in the cold, they still have a little: swim bladder still works, gills flap however infrequently etc. This generates a tiny amount of heat. And they bunch together in the deepest/warmest part of the enclosure which amplifies the effect. so they can be in a little tiny bit of not-quite-frozen-solid water which is very hard to detect.

that's my theory anyway and I'm sticking to it. :) Have had what started out as 6 feeders in an outdoor pond in w.TN for 11 years now and admittedly I have never checked depth of ice once it freezes over (which it doesn't do every year, it is TN after all.) But have never put more fish in and have dozens now. Including some who have clearly lived over from year to year, they didn't just hatch over winter from eggs--one of the originals I called Don Diego lasted until around 2008 and I think it took a raccoon to do him in. Although I get babies every spring as well so some eggs do survive as well.

Frostbite isn't a fatal condition. Being frozen solid all the way through is.
 
XanAvaloni, I think that's probably what they did. I heard of fish doing that but I never thought about my goldfish doing that. Good Point!
