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.
