BPs terrible legacy

I have been an avid fisherman in southeast Louisiana for most of my 47 years.I also have to admit iv'e caught plenty of healthy fish since the BP disaster.But two weeks ago that all changed. We caught several saltwater catfish (throw-backs)with tumors on their body.Whats worse is we came across a porpoise pushing it's dead or stillborn baby across the surface of the water. I have pictures of the fish and a very sad video of the parent porpoise. I have never in the thousands of fishing trips ever seen fish with tumors or dead baby porpoise.
