I still put 99% of the blame for drops in fish populations on the "commercial spearfishermen". Just look at those clowns on that TV show "Catching Hell". Those ringling band of brothers destroy the reef for $$$ and they are just the small exzibit currently on display. If legislators want to burn someone, turn on the tv and fry these people.
Ive also been spearing on scuba a few times since my original post on this topic. Its waaaay easier than freediving and there is no sport in it at all. Seriously, anyone can do it and most of the scuba speardivers Ive come across over harvest and poach. Free divers do it too but not everyone can go down 40-60' let alone 80'. My first tank dive, and no im not certified, was at 85'. And it's pretty difficult not to come up with fish on the stringer when your tank diving. I mean, your breathing the entire time so your more relaxed. And in my experience the fish would come right up to me(muttons, mangos, hogs, even grouper) The notion that bubbles scare the fish is bs, its more about your presentation Ive found from my experiences.
So my point was and still is, each individual freediver can only go so deep(average joe freediver) which gives the fish some type of refuge. However, you bring tanks into the picture and all the beer drinkers come on their boats and clean the reefs out. The % of freedivers who can consistantly dive down to 60' and more is very small and those guys are putting in work to be able to maintain that. Look at the med sea, they used to scuba spearfish that too until it got over fished..
Personally, I find alot more sport in Freediving than scuba and for good reason.
(Saw 2 guys today getting tickets from FWC. One guy shot a 6" hog and the other an 11.5" hog. $500 each and no fish. Im glad they're regulating some places, it's a start.)
