Last year I was fishing in the estuary in August for the Buoy 10 run. I hooked a very nice coho, netted it and had it on the floor of my boat. I then bonked it about 3 times til I was sure it was "knocked out". I then slit both gills so it would start bleeding. Next, I put a rope through the mouth and gills and lifted the fish over the side to bleed it.
As I was moving the fish back and forth to disperse the blood, all of a sudden the fish became alive! It quickly swam out of my hand grip. I was then holding on to the rope as it was torpedoing away. Just as the end of the rope was about to slip out of my hand, I clinched down hard and the rope held in my hands and then became limp. I pulled the rope in and there was no fish.
I felt absolutely sick and guilty. Not so much that I had lost the fish, but that the fish was bound to die a slow death from it all. I hope it was a quick death though.
So, anyway, from now on, I always put the fish in the net before I bleed it over the edge; it works a whole lot better.
