Hurricane Isaac May Lead To Fish Kills
A shot of a major fish kill in Bayou Chaland, Louisiana, which was attributed to oxygen depletion.Louisiana Department of Wildlife and FisheriesOfficials with the Louisiana Department of Wildlife and Fisheries are reminding residents in areas that may be impacted by Hurricane Isaac that
may occur as a result of the storm. Residents who encounter a fish kill are encouraged to report the kill immediately at 1-800-442-2511.Large amounts of rainfall across Southern Louisiana may cause fish kills, particularly natural waterbodies surrounded by lands converted from forests to agricultural land. High levels of rainfall may erode organic matter, carrying it into bayous and canals connected to lakes. Organic matter may consume high amounts of dissolved oxygen in the water suffocating aquatic life.Fish kills may also be caused by the rapid mixing of stratified waters or layers of warm oxygenated water over cooler anoxic water. In some instances, the result will be that the water can no longer support underwater life. In the past, tropical storms and hurricanes have caused fish kills in these types of waterbodies.The Louisiana Department of Wildlife and Fisheries is charged with managing and protecting Louisiana's abundant natural resources.
