Gulf oil spill will have a major impact on the fish and seafood industry. The Gulf oil spill has been ongoing for several weeks now, and it is already having an impact on this country's fish and seafood industry. The federal government has banned fishing across 62,000 square miles of federal waters across the Gulf. That means that fish and seafood is becoming more scarce, and the prices for what is available is going up. Crab is up to $40 a bushel and shrimp has gone from $4.50 to $8.95 a pound. And that is just the beginning. Prices will continue to rise, in supermarkets, fish markets, and restaurants to try to offset the rising costs. Eating healthy fish and seafood will become much harder for the average middle-class American. And just how healthy will the fish and seafood be in the months and years to come? People are already getting worried about contamination in the fish. How is it going to play out in the near and distant future?
