I support Bill Walker as well, however, since he is the captain (and boss) he is ultimately responsible for the actions of his professional employees. I doubt he could do anything to prevent the situation, but it is within his capability to attempt to explain the actions of his employee and also indicate if we can expect similar behavoir in the future.
The whole incident sounds a little over-blown, but I personally would like to hear their side of the story.
We will be seeing more of those destructive species and there is no reason to believe that in the very heavily dove locations within Palm Beach that the invasive exotic density can be reduced with a concerted effort on the part of divers.
Local and state governements dump litlerally tons of poisions (mostly herbicides) to control (not eliminate) undesirable aquatic vegetation in the freshwater canals that discharge to this area. If they are willing to dump that much toxins for control, allowing motivated divers to remove these fish has much less potential to damage the ecosystem. I guess my point is that, exotic organsims ARE A BIG DEAL!
