How to euthanize a fish was a question posed to my better half the Emergency Veterinarian this weekend and a question which she had never been asked before. With dogs, cats and other mammals the procedure is pretty straight forward, a fish on the other hand is a different species altogether.
Katy Meyer, DVM (my previously mentioned better half) has been practicing Emergency Veterinary medicine for nearly 32 years and currently owns Tampa Bay Veterinary Emergency Service and this question had never been posed to her, it's not like a client can wrap a fish in a towel and carry it into the clinic.
We probably all have had a gold fish or two which were kind enough to just go belly up in the tank and we flushed them down the toilet or simply threw them in the trash, but the fish in question was a mush larger Koi which had developed a large tumor hanging from it's side and the owner wanted to know, "how do you euthanize a fish".
This actually stumped my better half at first, but through the magic of the internet, Google, and a Veterinary resource website (www.VIN.com) she was able to advise the client of a humane method of euthanasia.
I could give a detailed and lengthy description of the euthanasia method, but let's just say it involves Clove oil (readily available at many retailers) and Vodka - yes they really drink the juice, and you know where to obtain Vodka!
If you want to read more, try this website: euthanize a fish, it explains very clearly how to painlessly euthanize a fish with out the guilt!
Unfortunately for her, Katy does not stock Vodka at Tampa Bay Veterinary Emergency Service so the client was able to complete the act in the privacy of their home!
