BALTIMORE (AP) — State environmental scientists are investigating the cause of a fish kill that left about 7,000 dead Atlantic menhaden in waters that include the Inner Harbor and Fells Point.
Jay Apperson, spokesman for the Maryland Department of the Environment, said that biologists went by boat on Tuesday to the area of Monday's fish kill. He says the area extended from the mouth of the Patapsco River, up the Baltimore Harbor to Fells Point and Fort McHenry.
Apperson says no dying or newly dead fish were seen and scientists believe the fish kill is over.
Because only one species was affected, MDE does not believe that the presence of a toxic substance caused the fish kill.
MDE doesn't know say when it will determine a likely cause.
