Despite oil cap progress at the Gulf, the future of fishing communities in the area is still uncertain. Tourism has slowed, jobs lost, and the economic damage is projected at $15 to $60 billion over the next 20 years. Seafood is a $3 billion industry in Louisiana, producing 30% of the nation's domestic seafood. A federal ban on fishing includes 1/3 of the Gulf, but most people don't realize that in open water, the seafood has been found mostly uncontaminated. Scientists with the NOAA (National Oceanic and Atmospheric Administration) have been conducting sniff tests to catch oil pollution.
