MS-222 is widely used in British Columbia to anesthetize salmonids and other
fish.  I cannot remember the exact dosage that I used to use or the phone
numbers, but if you contact John Ketcheson at the Pacific Biological Station,
Government of Canada, Nanaimo, BC he will be able to give you some useful
advice.  (Sorry about the phone number but I really cannot remember and it
is a LITTLE difficult to look it up from here :)  I *THINK* the dosage was
in the order of 0.05 g MS-222 / 5 l (sea)water, but DON'T quote me on that !
