Dr. Ed Cake, a biological oceanographer, as well as a marine and oyster biologist, has "great concern" about this fish kill, and many others in recent weeks, which he feels are likely directly related to the BP oil disaster.

"As a scientist, my belief is that this fish kill is 75 percent likely due to hypoxic conditions, not enough oxygen in the water to sustain life," Dr. Cake said. "Because it was both bottom dwelling fish and crab, and other fish from the middle of the water column, whatever caused this covered the entire water column. That gives me great concern. The scientist in me says there was some other triggering mechanism."

Dr. Cake believes the "triggering mechanism" is likely oil and toxic dispersants from the BP oil disaster.

Recent weeks have seen other huge fish kills. One occurred in Mississippi from Long Beach to Pass Christian, and another at Cat Island. The kill earlier this week in East St. Bernard Parish is of note, because taken in the context of the other two, all of these areas share the same body of water – that which comprises both of the Mississippi and Chandeleur Sounds.

On Aug. 18, a team from Georgia Sea Grant and the University of Georgia released a report that estimates that 70 to 79 percent of the oil that gushed from the well "has not been recovered and remains a threat to the ecosystem".
