How are you supposed to kill a fish humanely under the water ?
Follow the lateral line to the gill plate, place the knife crossways to the fish's spine (it's directly under the lateral line) and stab down with the blade angled forward about 45°. This severs the spine at the base of the skull.
Alternately on larger fish you can throat the fish by cutting through the fish just aft of the lower junction of the gills to the body. This cuts the main artery between the heart and gills providing the fish with O2, and bleeds them out in a matter of seconds.

I spent the rest of the dive trying to hide life from her including a very large lobster!

Thus depriving that fine lady of a good meal, and indirectly killing the multiple juvenile lobster that big one will eat in the future.

Apparently another club member goes around ripping off spider crabs claws![/QUOTE]
Male spider crabs fight for females. Generally the winner gets "leverage" on the looser and breaks off a claw. When the looser sheds a claw the fight ends. The the crab will then go through two fairly rapid molts. The first time the crab molts he'll have a half size claw, then go through another molt to regain the full size claw. It'll take a bit longer to ger to full muscle mass inside the claw.
Properly done the crab will yield a claw at a natural part line with little damage to the crab besides removing his chance to get laid for a few months. This will have little or no impact on the crab population and is the most humane and eco-safe method of harvesting seafood. I have harvested a claw from the same crab several times, so I'm sure the theory is correct in fact. Be aware that I've seen a diver "slip" when doing this and get a gash that took 17 stitches to close. Don't get distracted!
Diver harvest of marine critters is THE LEAST impact on the other critters of any harvest technique. By-catch (death of non-targeted non-saleable species) in dredging and trawling operations are often 6X to 10X the weight of the targeted species. Even recreational fishing by hook and line will kill 2 or more fish to each one landed. When a diver kills, he kills what is wanted and ONLY what is wanted. I may bring home 200 pounds of fish after a day's huntiing, but I only killed those who came home with me. That is roughly 7 fish on a dood day. 4 red snapper, 1 cobia, 1 Amberjack, and a grouper.
