HARTFORD, Conn. (AP) _ Connecticut has extended for another year a ban on taking alewives and blueback herring from most inland and marine waters.
The Department of Energy and Environmental Protection announced the prohibition Monday. The action was initially taken in April 2002 and has been extended each year since.
The environmental agency says its monitoring showed no improvement in population size during the past year. The ban is now extended prohibition through March 31, 2013.
Alewife and blueback herring hatch in freshwater, migrate to the ocean to grow and return to freshwater to spawn.
Historically, millions of river herring returned to Connecticut, but environmental officials say that by 2006, only 21 passed the Holyoke Dam.
The state says the exact cause of the decline in river herring runs is still unknown.
