A Representative for Coastal Zone Management is reporting thousands more dead fish in Plaquemines Pariah.
The fish were found yesterday behind a barrier island.
The agency says the fish included sting rays, catfish, and redfish.
Last week - thousands of dead fish were found in Bayou Chaland. The Department of Wildlife and Fisheries says the Crisis on the Coast wasn't responsible for those deaths.
Testing will be done on this latest kill to see if the oil spill played a part.
