State authorities say fish kill in St. Bernard Parish waters likely caused by low oxygen levels

St. Bernard Parish authorities have reported a large fish kill at the mouth of the Mississippi River Gulf Outlet, but state wildlife officials say it does not appear to be directly related to oil from the BP leak.

Randy Pausina, head fisheries biologist for the state, said Department of Wildlife and Fisheries workers are investigating the fish kill and that the initial conclusion is that it was caused by low levels of oxygen in the water.

Pausina said extreme heat can cause areas of low oxygen, especially when coupled with nutrient-rich water coming from the Mississippi River. The state opened several river diversion structures to help keep oil from penetrating the state's wetlands.

The fish were found Sunday afternoon, floating near boom that had
been deployed in the area to catch oil from the BP oil leak, and washed up on the shoreline, St. Bernard Parish government said in a news release.

Colder water can hold more DO (dissolved oxygen) than warm water. DO is how fish get their oxygen. I've done river water testing and saw first hand how rising water temperatures killed Salmon fry while they traveled in small streams prior to entering large rivers and the ocean.

During warm weather, urban runoff can have significant thermal impacts on small streams, as stormwater passes over hot parking lots, roads and sidewalks.

Called Beshel's Marina to find out how the Fishing reports were lately. Report was that it's a day by day situation. No live shrimp available right now.

Reported that dead zones are showing up in various areas. Said one day Crabs are alive in traps, next time the crabs are dead.

Is anyone else having similar issues? Hope the LDWF is following up on these reports of Dead Zone areas...
