mix 1 ml clove oil (can be obtained from a pharmacy or health food
store) with 9 mls vodka to make a 10 ml stock solution.
Place the fish in a container with one gallon of water and add the
10 mls of clove oil and vodka to the one gallon of water, and the
fish will just go to sleep quietly with no struggle. Clove
oil (eugenol) is used as an anesthetic in fish for surgery, and
the vodka is necessary so that the clove oil will dissolve in the
water. Its always very sad and a difficult situation when we
have to make a decision to euthanize any pet, but this method is
very gentle and is the best way to euthanize a fish.
||FWIW, my 2 cents is that there is only one or two
guaranteed quick and (relatively) painless ways to euthanize fish. If the
fish is large you can slice it right behind the gills or for smaller fish
that are impossible to hold you can just net them and slam them hard against
the floor, hard enough to kill them with the first blow. I've also thought
the garbage disposal may be a good option for the squeamish.
Other ideas that I don't particularly agree are quick or painless; putting
the fish in a diluted vodka cocktail, using an overdose of tranquilizer, or
putting them in the freezer.
||Bottom line is you do what you are personally comfortable with.
I was forced to euthanize a pretty little female guppy recently. After
some soul searching, I put her in one of those long bags you bring
fish home from your LFS in, drained out the water and very quickly
"snapped" it *HARD* on the widow sill. She never knew what hit her.
Only had to do it once. :_(
||Feed it to your Oscar or Jack Dempsy. There IS NO humane way to kill a fish or
anything else for that matter. Just grit your teeth and do it. No don't
flush it down the toilet
||On the other hand, it might pass the disease on to the Oscar... If it's
questionable about whether it's a disease or not, I'd stay away from that
||I have heard that a solution of ice water does the job somewhat effectively.
I personally prefer the sudden lethal blow technique. I also have the
luxury of completing the circle of life by feeding the poor soul to the
||I have to disagree with the ice cold water job... i once had to do this with a
gourami, but it took ages for the gourami to die :o(. My best preferred
method is by using a bottle of "anti fungus & finrot" treatment no 8. It contains
phenoxyethanol, which is a anesthetic. in low concentrations, it will
cure fungus, at higher concentrations, it anesthetizes them, and a large
concentration will kill them. This is the best way to do it as it firstly
anaesthetizes them then kills them => no pain!
||My preferred method: use a fish anaesthetic called
Finquel MS-222. An overdose will peacefully euthanize a fish. You can purchase a small bottle of the stuff
for under $10 from Argent Chemicals. Their website is http://argent-labs.com/
put mine in a cup of water and then put them in the freezer.
This method gradually slows them down until they pass. I
think that this method provides the least suffering.
know about the freezing method, because I don't think that slowly
freezing to death would be very fun (even if you do go brain numb
after a while), but the one time that I've had to euthanize one of
my fishies, I used a similar method. Instead of putting the fish
in the freezer, you drop them into ice water. Supposedly quite
quick & painless.... The vodka method sounds good if you have
some of it around though....
really need to off their existence the method I have been told
that is most humane is to freeze them. Place fish in a small Tupperware
type a carton and set it in the freezer. They get brain numb
before the actual death point and do not really suffer at all. It
makes sense brain wise and is kinda natural in method.
and Monte Bickel of betta fame had a large black arrowana in an
130 gallon tank named Barney. He tok care of their culls.
I was also told by Monte in a quieter moment that another way to
cull was to place the fish in a bag and put it in the
refrigerator. The betta then just went to sleep. The best
way is to find a fish store that will trade you for supplies, live
food, etc. Sometimes they'll even buy them. Bonnie
McKinley of betta fame used to trade a betta or two for live food.
I don't/wouldn't cull my fish, but if you are one of those that
do...(which I have no problem with) I think the easiest way (on
both fish and human) is to put the fish in a small container of
water and put it in the freezer. This is supposed to be painless.
