I have no reference for you but I support your dropping fish larvae
into alcohol as a 'humane' method of killing them.
I've killed a lot of fish larvae. I usually drop them in ethanol. One
second and that's it. They're dead. It seems like a perfectly good
and 'humane' way to do it to me.
A method suggested to me once was to put them in the freezer
and let them cool down. Seems more like torture to me than a
humane method.
