That'due south why most aquarium owners choose to do the muddy deed themselves. Information technology may sound gruesome, but it's a useful skill to have. If y'all desire to exist a fish keeper for life, this is all function of the job.
And today, I will show you lot the best way to euthanize a fish.
How Do You Humanely Kill A Pet Fish?
Disclaimer: All the fish in my tank are currently good for you and happy, then don't worry! I won't be killing i of them for the purpose of this guide. Instead, I will be using Angus, the stunt double…
He doesn't look happy about it, does he? Information technology's almost like he knows his fate.
There are two commonly used methods to euthanize fish.
While both are considered humane, one is less gruesome than the other.
So, let's starting time with the piece of cake method:
Method one: The Clove Oil Bath
If yous don't similar gore, then this is mayhap the best way to euthanize your fish.[one]
You simply need one product…
Clove oil. I personally utilize this one…
This stuff works wonders and is recommended by the American Veterinary Medical Association as a humane style to kill fish.[2]
You see, it works like the anesthetics that vets use, which are not available to the public. It puts your fish to sleep before killing information technology without suffering.
If you plan on keeping fish for life, then I highly recommend keeping a bottle of clove oil nearby, but in instance.
Okay, now that you take a canteen of clove oil on hand, follow these steps to humanely euthanize your fish…
Pace 1: Catch Your Fish
Fill up upwardly your bucket with water from your aquarium – a gallon will practise for virtually fish, although larger fish might demand more than.
Catch your fish and place it inside the container. Be gentle and cause as little stress as possible.
Pace two: Mix The Clove Oil
You can't add your clove oil just yet. You run into, it's an oil. And if yous add it at present, it would simply float on the surface of the h2o.
So, take hold of a small container – pill containers piece of work great. Make full the container with water from your tank and add 4 drops of clove oil.
Note: This is for fish less than 4 inches in length, increase the corporeality of drops for larger fish.
Put a lid on it and give the container a proficient milk shake, until the water turns a milky white color. Your clove oil is now mixed.
Footstep 3: Add The Clove Oil Mixture
Slowly add the clove oil mixture to the container with your fish while stirring gently with your hand. Y'all should run across the milky mixture spread throughout the container.
Afterward a few minutes, your fish should terminate moving. It may fifty-fifty go abdomen upward…
Only it's not expressionless but yet… It's simply knocked out. If you expect closely at your fish's gills, you should meet them still moving – a sure sign that your fish has been put to sleep.
If your fish is still pond around later on 5 minutes, add a couple more than drops of the clove oil mixture.
Step iv: Add A Stronger Dose
Now that your fish is asleep, it's time to put him to rest for adept.
Scoop some h2o out of the container with your fish and add another 12 drops of clove oil mixture. Just similar before, shake it upwardly until the clove oil mixes thoroughly.
Add the clove oil mixture to the container with your fish and wait.
It should take less than 30 minutes before your fish's gills terminate moving. In one case the gills don't movement for ten minutes, the fish has been successfully put downwardly.
If yous still meet gill motion after xxx minutes, add together more than mixture.
It may take some time, but many aquatic life experts detect this the most comfortable method of euthanizing a sick or injured fish and in accord to upstanding standards.
Now, permit'south await at a quicker way to euthanize your fish. Be warned – if you accept shaky hands or a weak stomach, y'all should probably stick to using clove oil and skip this second method.
Note: If you lot have a much larger fish, overdosing on clove oil might not impale information technology. If this is the case, you will take to perform the next method while information technology is sleeping.
Method 2: The Stun and Stab
The stun and stab is the quickest manner to acceleration a dying fish. And, it works just how it sounds. You hitting your fish with a blunt object, and and then stab information technology with a pocketknife.
At present, I know that smacking a fish with a edgeless instrument doesn't sound humane, but if done correctly, it's quick and painless.[3]
The reason a solid whack does the job is that it disables the nervous system so that your fish doesn't feel anything.
Now, information technology'due south possible that the force from the blunt object volition kill your fish outright, especially if it's a smaller fish. But just in case the hit only knocked it unconscious, make sure it is expressionless by stabbing its brain with a knife blade – see, I told yous information technology was going to get gory.
All-time of all, you accept all the tools you lot need for this hiding in your kitchen…
- Aluminum foil
- A blunt object – I utilize a rolling pin
- A sharp pocketknife
Read over these instructions before you attempt this technique. Just how humane it is entirely depends on your ability to work quickly.
Pace ane: Grab Your Fish
Identify a square of aluminum foil down on a flat surface.
Quickly remove your fish from the tank, identify it in the centre of the aluminum foil and fold it over.
Fold the foil over the pinnacle of your fish. This is to preclude claret, guts and brains from flying everywhere. Putting down your pet fish is bad plenty without existence covered in its actual fluids… Trust me, information technology'southward a mistake I will never make again.
Step 2: Hitting Your Fish With A Blunt Object
Next, y'all are going to hit your fish as hard every bit yous can through the aluminum foil. You are aiming for the head. If struck properly, this volition cause your fish to immediately lose consciousness.
At present in some instances, this might kill your fish outright. But it's no guarantee. That'southward why nosotros are going to follow up with one last step…
Stride three: Stab Your Fish
Now, you lot are going to slice into your fish through a procedure called pithing. The thought is to pierce through the brain of your fish, which will impale it instantly.
Don't worry… Because your fish is unconscious, it won't experience a thing.
Where is the brain of your fish located? Just backside the eyes.
In order to accurately hit the encephalon, I recommend piercing just above the eyes horizontally, pushing your pocketknife bract through.
It was gruesome, but you lot accept at present successfully put down your fish.
How Not to Kill Your Fish
The methods listed above are humane ways to euthanize a fish. A quick search on the web reveals many ways that yous can kill your pet fish. But very few of them are actually humane.
Yes, I know that scientists still argue as to whether or not fish tin can experience hurting…[four]
Merely if they tin can, do you really want your fish to experience agony in their last moments?
I know that I don't.
And so, let's take a closer look at how you shouldn't kill your fish.
ane. Flushing Your Fish to Kill it – Don't do it
Will it kill your fish? Maybe.
Is information technology humane? No.
Information technology's deplorable to say that this is probably the nearly mutual method used to deal with a dying fish by a vast bulk – often by beginners who bought a betta fish as a novelty while waiting in line at checkout.
Why people think that flushing a toilet will instantly kill a fish is beyond me. Certain, the change in water temperatures, chlorine and other toxins might kill it, but it's not unknown for cold water fish to survive.[five]
And even if it doesn't, is a deadening expiry surrounded by homo poop a humane way to become?
2. Carbon dioxide
Volition information technology impale your fish? Yes.
Is it humane? No.
Carbon dioxide when injected into the h2o can cause fish to suffocate. Even so, the process is non instant, and fish are aware that in that location is not enough oxygen in the water and spend their concluding moments stressed.[half-dozen][vii]
three. Using an ice bath to kill your fish
Will it kill your fish? Yep.
Is it humane? Maybe.
Okay, and so this i might be humane, but it depends on the size and type of fish you are dealing with.
Ane scientific study on Zebra Danios establish that a cold h2o bath (less than 39 degrees Fahrenheit) can exist an effective and humane method of killing your fish, so this method may piece of work on tropical fish less than 2 inches.[8]
However, if ice touches your fish, then water ice crystals can course on the gills, which may cause pain. Also, this method is not suitable for whatsoever cold-water tolerant fish, such as koi or goldfish, which tin can survive at cold temperatures.
Other scientists state that cold water euthanasia should be skipped completely, stating that this method has the potential to crusade unavoidable hurting.[9]
So, the jury'south out on this one.
Oh, and obviously throwing your fish in the freezer an water ice bucket and waiting for it to ice over counts as inhumane.
4. Leaving your fish to suffocate – Don't do it
Will it impale your fish? Yes.
Is information technology humane? No.
Information technology might surprise you to learn that fish tin breathe oxygen. But only when it is dissolved in water.
Outside, on dry out country, your fish will suffocate. And, information technology isn't a quick procedure. As its organs slowly neglect, your fish will endure. Information technology's a painful and horrible way to go as its outright asphyxiation, your fish deserve better.
5. Using vodka to kill your fish – Don't do it
Does it piece of work? Yes.
Is it humane? No.
While an alcohol bathroom will impale your fish, it as well burns the gills during its final moments. [x]
half dozen. Boiling water
Placing your fish in humid water?
But… No.
Seriously, don't use any of the methods in this section – your fish will suffer if y'all practise.
Decision
Just to brand information technology clear… I only advocate euthanasia as a terminal resort, when all other options have been exhausted.
I do non condone the killing of fish just because they are an unwanted pet. You can't just kill an animal when yous are bored of it… That'due south horrible and fish slaughter.
If you have a healthy, unwanted fish – don't kill it. Contact your local aquarist customs first. There are also numerous Facebook groups defended to rehoming fish. In that location are plenty of people who volition be happy to take your fish off your hands!
Okay, with that out of the way…
I know it tin be sorry to say bye to a much loved fish, particularly 1 that has been with you for years.
But if you take to euthanize your fish, the least yous tin can exercise is brand sure the last moments of your fish-buddy's life are pain-free.
And recollect… Your fish is now in fish heaven and is likely very happy. So you don't have to feel too sorry about it and have it every bit a reason non to have any more fish.
