Believe the product you are inquiring about is roetone. Check with your local
agricultural extension about it.

I am enquiring on behalf of a farmer, who needs to capture or kill an excess
of carp in his farm dam, about the name of a product that incapacitates fish
by (I think) oxygen deprivation. I know that some such product exists but
need to know where one can obtain it. I also need to know whether fish
killed in this way are edible or not. Can you help?
