"It's been a rough summer in some of the waters around Plaquemines Parish in Lousiana -- first, hit by the oil spill, and now, hit with fish kills .
'This is an extremely large fish kill, and there are many species in there,' said Plaquemines Parish President Billy Nungesser. 'It's not just one group of fish-- it's redfish and trout and flounder. All species have been identified in this fish kill.'
Plaquemines Parish officials spotted a massive fish kill on Friday. Hundreds of thousands of dead fish were floating west of the Mississippi River, in Bayou Chaland. It came several days after the discovery of starfish kill in nearby Barataria Bay. Then, on Monday, came the discovery of a dead baby whale near Venice.
Whether any of those incidents are related to the oil spill remains a big question. Some local officials believe more testing could provide an answer."
