    For me, i put in plastic bag and band against something. But I am quite depressed for a few days after doing that. Did that twice before (one to a goldfish, and second time to one of my iriscedent shark). But to me, that was the quickest way for the fish to die.

    i think for small fishes just use boiling hot water pour over them. they die very quickly this way, in a matter of seconds. and they won't struggle much, esp if they are sick/dying/suffering already.

    had to do that to one of my dwarf honey gourami today and was quite sad... but at least i don't see it suffering everyday in the tank and wondering when it'll pass on.

    Hey all,

    I have been thinking of this question for a long time and the only humane way I could find myself doing is to release them "unwanted" fries in the river / drainage system (the drainage seems to be very clean to my surprise) behind my place. However, me being not a local here, wanna know if it is illegal to do that?

    TO pay a fine is secondary..
    the ecosystem may get disrupted, which is far more worse.

    Why not give the fries to someone really wanted to raise it up? Think giving FOC in our forum is the best and humane way to move forward...

    Yeah ! Culling sick fishes are like killing a cancer patient because they have diseases, why not give them some chance and let them survive until they die ? thats what i did to 1 of my rams. Culling of fishes is not encourage by me

    I euthanize my fish by taking some ice cold water, filled with crushed ice and dropping the netted fish into it. It goes into cold shock and you can see it stop breathing almost instantly. Then you just stick it into the fridge to become a fishcicle and after a couple of hours, you can throw it away.

    Don't throw it down the toilet bowl, because there are rotors in the sewage system that keep the flow going. The fish will eventually become sushi.

    nice one... most of the time the fish either cannot survive the medication given and die or i'll wait out it's last few days. Does anyone want to give some comments on culling of young fish? some fish owners do say they cull young fishes, to protect the strain? their value? or the greater good?

    The best way to cull young fishes are simply to use a culling machine that could be a cichlid or a snakehead.

    Beheading/Spinal Separation

    Using a sharp knife or cleaver to remove the head or separate the spine will also quickly euthanize a fish. The cut must be made quickly and cleanly, causing death, not a mere injury, with the fish being taken out of water and dispatched as quickly as can be safely done. If done properly, there may be some twitching and flapping from the fish, most of this is due to nerves but there are some tests that show brain activity may last for a few seconds after decapitation.

    Pro’s

    • There is no question about if the fish is dead or alive like there may be with other methods

    • It is over relatively quickly or even instantly if done properly

    • Most people have a sharp knife available, and many have fisherman friends who are familiar with quickly be-heading fish

    Con’s

    • A somewhat gruesome procedure that some people can not stomach

    • The head may be difficult to remove with one clean stroke, so follow up “sawing” action may need to be used if the first cut fails, the fish will likely be alive for this

    • The fish will need to be removed from the water and held down, so for those moments it will be stressed, gasping for air and likely struggling

    • If not done properly, the fish may suffer longer as they bleed out or the person struggles to complete the task

    • Caution must be used with any sharp blade to avoid injury to the person



    the sentence in bold makes me sick in my stomach... yuck

    Yeah, a bit scary, and a bit cruel to do that to the fish.

    Anyone thought of ph shock method, just came to my mind.(Wondering whether it works)
    By releasing low ph fishes into high ph water and vice versa.

    Hi all,
    The original poster did not mention the purpose of culling. Is he/she a breeder wanting to cull anomalies in young fishes? I would recommend oscars or snakeheads. At least the young ones serve as food and did not die in vain or lived a life without purpose. Is it to destroy infected fishes that are beyond treatment or ??? Need we speculate?

    To kill a fish fast and quick, is to use extremes. Boiling water or ice in a bucket. Sure die and any perceived pain is brief. Decapitation is just as effective and if you don't have the stomach to look at death in the eye, bury them quickly in the planter box to be recycled as fertilizer.

    To feel for a fish is quite frankly, a little beyond me (except for the pinch in the wallet). No need for sermons or prayers for a safe trip to the afterlife. No need for sentiments either, for there are greater issues in our daily lives to worry about.

    Whatever one choose to do, for gawd sake, don't dump them into local waters. The ecosystem is screwed up bad enough as it is and while one might think it's humane, that's the worst possible option.

    TDS difference greater than 3 times is more lethal than pH shock, which is why overnight drip acclimatization works best.

    To put a end to it's life due to too sick, will be using a knife, cut the spinal, between the head and body, the most decent way, fast and no much pain.

    Read it some where on a fish book.

    For anabantids, you may wish to cup them underwater and deprive them of access to the surface to breathe. Painless for sure, but may be cruel considering the time period of struggle before death.
