Re: Best way to kill a fish?
I've seen people cut the gills on salmon to bleed the fish but it doesn't appear to kill em right away. My stab in the spine / brain kills em about as quick as your method and if I remember I cut the gills also after the braining. I've got to leave the heads so that I have something to carry the fish by on the walk back to camp or car.
Bleeding them out helps to eliminate that coagulated blood in the meniscus under the spine and along the spine itself.
