preserving dead fish

Postby xander » Sat Sep 03, 2005 8:48 pm

Fish die. Its sad but they do. One died recently that I have had for over 10 years. I would like to preserve it as I don't feel I'll find another like it. It was a Bunocephalus amazonicus. I would like to keep this specimen in as preserved a condition as possible. I have wanted to do this with past fish as well but have never been prepared for it. I talked to a taxidermist guy who also preserves insects and said for fish that the best way was to preserve in alcohol. I am wondering if anyone has done this and if so if this method is satisfactory. I put this quy in a jar with 91% isopropyl alcohol.

Vodka works pretty well in a pinch too.

The best method of preserving a fish is to use a 10% formalin solution (formalin is a 37% solution of formaldehyde), as you need to fix the tissues. Alcohol will preserve the fish, but not fix tissue.

After two weeks in formalin (which you have to handle carefully, as it is carcinogenic), it can be transferred to water for a couple of days (to flush out excess formalin), before long term storage in alcohol.

Why? Surely not because its missed. Must be scientific reasons I assume.
