Connecticut’s Department of Energy and Environmental Protection why thousands of fish died in the past week in the state’s coastal waters. Multiple natural fish kills were reported during the past week. The kills were reported in several locations on the Thames River between Norwich and the U.S. Naval Submarine Base in Groton, in the lower Connecticut River, in Clinton Harbor and on the Quinnipiac River.
Thousands of Atlantic menhaden, and smaller numbers of other species were found dead at each location. The population of Atlantic menhaden has grown in local waters for the past two years, most likely due to limits placed on menhaden harvest along the Atlantic coast. Menhaden are caught commercially and made into animal feed and used as bait in lobster, crab and other fisheries. FULL REPORT
