Yea I don't get that either...read somewhere that rec takes more hogs though but I'm not sure about that. I can only speak from what I've seen but I think the hogs nearshore in south Florida need a break more than anything. Almost every shore dive I do here I usually only see fish just at 12" or less it's even worse in the keys
there are still big hogs real close you just have to know where to look but yes I have seen a decline over the years.
