Normal fish kills cause "fish to come to the surface to be in distress, flopping around, and slowly they die, and new ones come up. This was not observed in any of these kills. All we had was a massive amount of dead fish coming to the surface"
Comments by Dr. Ed Cake, a biological oceanographer and marine biologist on the recent fish kills, as reported by Dahr Jamail in today's report for Inter Press Service:
- "Great concern" about this fish kill [of 5,000-15,000 fish floating dead on Sunday in St. Bernard Parish], and many others in recent weeks.
- "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."... likely oil and toxic dispersants from the BP oil disaster.
- "A fish kill from a red tide, as I've observed, causes fish to come to the surface to be in distress, flopping around, and slowly they die, and new ones come up. This was not observed in any of these kills. All we had was a massive amount of dead fish coming to the surface."
- "I was amongst all these dead fish in St. Bernard Parish... And there were off-bottom fish there as well, which was the same thing we had at the fish kills at Cat Island and Long Beach-Pass Christian, so I see a trend here. Prior to the BP oil spill and the widespread applications of dispersants in all three of these recent fish-kill areas, we have never had evidence of such widespread kills."
Louisiana officials have blamed the most recent fish kill solely on "hypoxic conditions caused by extreme heat mixed with nutrient-rich waters," the report adds.
