River Herring and American Shad
PROJECT REPORT: Click here and on "River Herring and American Shad" |
N.H. Fish and Game's Marine Fisheries Division monitors the annual spring spawning runs of anadromous fish, such as river herring (alewives and blueback herring) and American shad, in six coastal and estuarine river systems along the coast of New Hampshire, with the goal of restoring runs to historic levels. Anadromous fish migrate between the ocean and freshwater during various life stages.
Spawning Run Updates
This year (2013) Fish and Game staff started opening the Department’s seven fish ladders at the beginning of April in their efforts to monitor anadromous fish spawning runs in New Hampshire’s coastal rivers. The following chart provides preliminary information on the numbers of river herring and lamprey being tallied through the Department’s head-of-tide fish ladders.
