I think it is fine if you are going to eat whet you catch. The advantage of spearing fish, is that you choose which fish you are going to catch. With a hook and line, you dont get to choose, therefore have a bycatch.

Then it's ethical.
OceanusDC:<snip> We hear about animals tangled in fishing lines and dieing needlessly. We see lures and hooks and mono-line all over wrecks and other dive areas causing diving hazards and again, trapping fish to die.
<snip> I dont foul wrecks or other dive sites and holding onto a big fish while spearfishing especially while free-diving can be a heck of a lot more challenging than sitting strapped to a boat chair! BUT, I think they are both sports. From an environmental standpoint though, I think spearfishing hedges above hook and line.
SpearSlinger1:I think there's something that I neglected to mention earlier, having fished hook and line for even more years than I have spearfished and much more often. Hook and line is easier and more efficient, but in no way less sporting than spearing. As a part of a whole user group, particularly in a blood sport, it's important to not alienate each other with cheap pot-shots or the bunny huggers will eventually have it all banned.
It's a mute point because it doesn't happen and even if it did the same could be said for spearfishing as for hook and line.As far as the 'sport' or string fishing I guarantee you that if fish were not mute, that if they could scream and squeal like a pig or dog, not a single woman would ever cast a line and half the men would give it up.
