injured gar

[demjor19]

freeze the fish, it's one of the best ways to euthanize...you could smash it like jordan was saying (which is also effective), but that's somewhat messier.

either way, i agree with richard and jordan on the boiling issue...not going to work with gars by a longshot (longnose? sorry ) and freezing is faster and less time-consuming than boiling anyway.

i've found introducing a 10" gar to a 15" Polypterus weeksii can also be an effective method for 'euthanizing' a gar...

...not that that was done on purpose!!!--

lol! i didn't say smash! just a good solid blow to the head. i have only done it twice in my fishkeeping.

haha, guess i did use a bit more graphic wording, but the practice is the same...and there's nothing wrong with it really...can just get messy. i've used it before, but then again, i have generally been preserving specimens in the past several years. perhaps a dead gar collection photo series is in order --

PS - maybe i can then start a thread "largest gar collection???" sorry...couldn't resist

Well it could be the Largest and most diverse outside of any Museum collection...For that matter it may be more complete than most US museum collections...

Lets see some pictures of my dead white tropical gar you have lol lets see those pictures

glad 2 hear uR li'l fella's on the road 2 recovery... cheers...

okay the oxygen would be removed from the water through the bubbles and would re-enter the water but very slowly, so if you boil water, allow it to cool and throw in goldfish, it'll die. there's no way i can be wrong with that. i've checked with a couple of people who've tried it first hand.

if the bubbles leaving boiling water are all of the oxygen in the water....then why does it never stop boiling until you take it off the heat? how much oxygen is in there??? i'll agree warmer water does hold less oxygen, but i disagree w/ your theory. the people who tried this experiment...what water did they use? they probably just threw the fish in cooled off tap water (uncycled or conditioned).

Also, as polypterus said, gar breathe air so how can you compare this to your goldfish theory??

Temp pressure and salinity / turbidity are all factors in what the DO content of water is. While boiling the water will remove a good amount of DO as soon as it begins to cool the oxygen will replace it's self. The only way this would work is if you where to replace the oxygen with Nitrogen thereby preventing the water from gaining back DO..

What you are describing is likely just dropping a fish in hot water thereby killing it through sudden thermal shock. Your not going to kill a fish by boiling water and allowing it to cool unless you where to replace incoming oxygen with something else as it cools.
