From:- Cheryl Lawson. For humanely
killing/culling fish. Try the following formula
"First mix: 1ml - Clove oil
together with 9 mls Vodka which will make a 10 ml stock solution. Place
fish in a container with 1 gallon water and add the 10 ml stock solution
to it. The fish will go to sleep quietly. The clove oil (eugenol), is
used as a mild anaesthetic in fish for surgery and the Vodka is
necessary to dissolve the clove oil in water. While waiting, have a tot
of Vodka yourself."
