According to the Mississippi Department of Marine Resources, oysters, fish and other wildlife could be impacted as record amounts of freshwater head down the Mississippi River toward the Mississippi Sound.
Scott Gordon, Director of the Shellfish Bureau, Office of Marine Fisheries, explained that: “Oysters will suffer because they’re a stationary species; shrimp, finfish and crabs, which are mobile, are expected to be able to move ahead of freshwater entering the salty waters of the Sound, and the effect on the adults should be minimal.”
Other waters in South Mississippi could see an impact from the floodwaters coming down the Mississippi River. “The freshwater streams here could get invasive species,” Gordon said. They include Asian carp, such as bighead, silver and grass; cichlids, including Rio Grande and Nile tilapia; and mollusks such as apple snails and zebra mussels.
Among flora, hydrilla, salvinia and water hyacinth are expected to increase in these streams, as well as freshwater phytoplankton, or algae. Algal blooms could lead to fish kills.
