bigbulls: I have to say, I've never heard about the negative impact of dolphin populations. And I really like dolphins. And tehy seem to really like people. I go sea kayaking and the come up and look at me and play around me, etc. Very fun, joyful animals whose joy I think is contagious. When you say they are overpopulated, what do you mean?
I mean... spend a day fishing from one of the many Gulf piers and you will literally see hundreds upon hundredsof dolphins.
They have literally learned to target boats and piers for easy meals. Day after day after day dolphins will hang around a pier or follow a boatwaiting for a hook up and catchthe now slow moving fish that you have on the endof your line and eat everything but the head. I watch them all the time teaching their young to do this year after year. It doesn't matter if it is a snook, snapper, grouper, or a 50 pound King Mac they get it and hold on to it until until it is all gone and you pull up a head. They literally hear the line buzzing through the water and will come from East and West directly to the fish on the end of your line.
Picture that you are hunting and you shoot a 150" deer only to have a pack of wolves rush out from behind your treestand and devour it before you ever get down from your tree. Do this several times a year with deer from does to big bucks. Yep, they are beautiful and wonderful to watch when you aren't hunting. Same thing happens to your family members and hunting buddies. They hear a truck pull up to the field and they come a running waiting on you to make an easy kill for them.
