Alligator + ice?

richard,

slightly off topic...when gar are under a frozen body of water how do they come up for air? or is their metabolism just slowed down so much they dont have too?

LOL, I was just about to ask the same thing! I though that they have to have access to air at all times.

It is a combination of factors. As temp goes down Dissolved oxygen goes up so there is less need for supplemental breathing. The metabolism of the fish also slows requiring less oxygen than in warmer water.

that's what i figured. i just wanted it verified.

thanks,

Rivers and lakes are not small ponds..Fish can find a happy place in multimillion gallon habitats. be careful about ever thinking "what works in the wild" will ever work in your case or circumstance in captivity.

As said by most here I would not try this one...It will not work out well at all....

umm we'll i know this is sweden but if the pond is out doors how is it differn't from a pond or lake in the wild where there are gars like said before if it doesn't freeze sold then why wouldn't it work keep in mind he said he would drill a hole to feed them and if he kept the water we'll oxygenated then why not

if it doesnt freeze solid then why drill a hole to feed??? also they probably wouldnt even have to feed through the winter months if they did manage to survive

when i say solid i mean all the water freezes down to the bottom so if that happens the fish are dead but if it just freezes over then you would need to drill a hole plus it stays bellow freezing there for a while so i think they would need to eat a few times but that being said it might not work after all at least in sweden but gars can be kept in places where it does freeze over in the winter and thats what i've been trying to say

what body of water actually freezes solid?

There is a very very big difference between a pond and a lake. The ecology of both of these are very different from each other.

Just to point out one example:

Ponds are very small bodies of water with little ability to hold heat or provide a proper thermal stratification for the fish to find a suitable stable temp. This is why Gars in the wild, in northern waters, either live in Large rivers or large lakes. You do not find them typically in shallow waters or in small lakes and ponds in areas that freeze for more than two months.
