frozen fish?!?

A pond that is at least a foot deep will NOT totally freeze (or at least shouldn't)...

At the bottom of the pond will be unfrozen water, around 37 degrees farenheit.

here do you getthis idea?
 
i get mine from maintaining my dads pond and doing research ! 18" is what is generally quoted

If he's refering to the unfrozen water below, it's all thanks to the molecular marvel that is water. Rather than being more dense as a solid than a liquid (as are most substances), water is most dense at ~4 degrees celcius. Therefore when a body of water begins to freeze, the coldest (solid) water will form at the surface floating on the denser liquid water below. The liquid water at the bottom of the body of water will be about 4 degrees celsius, or 39.5 degrees fahrenheit.
 
Freeze tolerance is a complex adaptation that wood frogs can survive being frozen, they have a cryoprotectant glucose that helps it retain water,they also have proteins in their cells to help withstand the freezing process. But when the frog freezes it is only the outside spaces around the cells ,never inside the cells. If cell were to freeze the frog would die due to cell trauma caused by the the jagged crystals formed in the freezing process.The minimun point of no return temperature is about -25 to -23 degrees fahrenheit, putting them in your freezer at home will kill them. So your gold fish freezing friend is pulling your leg or you have misunderstood what he was saying. :)
 
How deep water must be varies dramatically with your location. 18 inches in Wyoming wouldn't cut it, I promise. However, it is really better to keep an area of the surface completely ice free to allow oxygen exchange, otherwise the fish may burn through the oxygen in the water and suffocate.

As for freezing them--best test: if it sounds ridiculous, it probably is. Yes, some fish can tolerate much cooler temps without harm, but tropical fish are certainly not on that list, and there is a limit to the tolerance of even cold water fish.
 
up north some of your small shiners can survive being incased in ice. I have seen this first hand not by attempting it but by seeing it happen in the wild. I would not recomend doing it or even trying it its mean and not something I would say is easily reproducible.
 
sounds like bs, but it's true. Goldfish can survive incased in ice. I've seen goldfish frozen at the bottom of a pond, and seen the same goldfish thawed out the next spring. Not exactly an ideal hubandry technique, but it can happen.

Actually, I knew that,(although not the actual temp of the 'thick water') Thank you though.
I was mostly referring to this:

I have also seen 18 inches quoted as minimunm for goldfish ponds, judgemax, but I am very nearly certain that in Vermont, I have seen water freeze Much deeper than this.heck, the ground freezes several feet down...
 
Fine. I'm buying some feeder goldfish and freezing them. I will post the results on this post. :p:
