To spear...or not to spear?

I agree with the idea of registering and collecting more data. But I question the effectiveness of "slot limits" or size restrictions. This is much easier to accomplish with hook and line. You can actually measure the fish and then release it if it is not within the legal size range. Not so easy for a spear fisherman. I would also be very concerned about the situation above about big lake trout being harvested as they move in shallow to spawn. I think details like this need to be looked at very carefully and have "closed season" time periods to protect large spawning fish.
