The other night I was watching the "Snakehead Invasion" show on National Geographic.
During the program it showed a DNR Officer/Biologist putting a Snakehead into a tub of clove oil before cutting it open and inserting a radio tracking device into the fish. He stated that it "Puts fish to sleep."
Surely the tub was a mix of clove oil and water but I'm not sure of the ratio.
Has any one out there heard of this or know of other ways to sedate fish? (not completely knock it out)
