Nice, Dan. I guess if one old barnacle could do it, maybe you're suggesting everyone should? :/ Back in the day folks speared Jewfish for sport, and paper companies dumped tons of chlorine in what were formerly, and are now again, trout laden rivers. You think we should go back to that?
Wookie, you interpreted differently than my intent.
I think it is important for divers to know that THEY should not do certain things. However, I think the reasons for this need to be clear, and not fictitious.
Divers should know it would be illegal for them to touch a turtle, or to attempt to remove a barnacle. But...
Divers should also know enough about turtles to know that they are very active in symbiotic relationships with organisms that CLEAN THEM ( spanish hogs, cleaner shrimp, etc), and that there has been one person that was able to achieve this level of harmony with turtles. One of the ways that critical imbalance of a marine ecosystem can occur, is when the "cleaner fish and shrimp" are killed. If a manmade event kills off the cleaner station organisms, then the big fish will all leave, or grow sick and die. Turtles do have strong symbiotic relationships with the Spanish Hogfish--they have a special pose that brings the Spanish hog in, and then the Spanish hog spends lots of time cleaning and eating
You know, in the old days, back in the 50's , 60's and 70's, the oldtimer spearfisherman that were shooting the jewfish, were laboring under a misconception...a misconception that was taught to them by America's educational system. I clearly remember elementary school and highschool classes in the 60's and 70's--and they were TEACHING that "the ocean was an inexhaustible source of life/food".
The oldtimer spearfisherman had no sense that what they were doing would ever change anything.....at least not in the 50's 60's and 70's....As we hit the late eighties and early nineties, it was quickly becoming apparent that jewfish were disappearing, and we were seeing this in the mid nineties to late nineties with hogsnapper.
We still had a "big game hunter" mentality to spearfishing in the early nineties...but it was being "educated into extinction"
By 2008, the spearfishing dinosaurs were a tiny minority, what was left had evolved , and were nothing like the pioneers to this in the 50's and 60's. The few you see today tend to be highly selective in what they shoot, and they no longer do any "damage" in the grand scheme--today the real damage is done by long lining and netting by the big commercial fishing fleets.
The jewfish actually disappeared completely on the shallow reefs around 1989, and this ended their commercial value ( cat food ? ) , about the same time spearfisherman were also discussing how they should not shoot them anymore...but considerably too late. Fortunately the Jewfish were still on the very deep tech wrecks, where I got to see them throughout the 90's.
