Hudson River Fish in Trouble:
10 of 13 Signature Hudson River Fish are Declining

 
In Serious Jeopardy: Many Hudson River fish species are in serious long-term decline and may be at risk of collapse if aggressive measures are not taken quickly. The NYS Department of Environmental Conservation held a series of meetings with area fisherman and other interested parties to develop recommendations for the Atlantic States Marine Fisheries Commission (ASMFC) to determine the best methods of protecting this fishery. The Pisces Report, a recent study commissioned by Riverkeeper, found that ten have declined in abundance since the 1980s: American shad, Atlantic tomcod, bay anchovy, alewife, blueback herring, rainbow smelt, hogchoker, white catfish, weakfish and white perch. Only three species—striped bass, bluefish and spottail shiner—have increased their population, due to circumstances that favored them. Contrary to public perception, the Pisces Report indicates an increasingly unstable ecosystem in the Hudson.

Major causes include:
  • loss of habitat and spawning grounds,
  • overfishing and ocean bycatch,
  • low dissolved oxygen from sewage plant discharges, and
  • impingement,entrapment and thermal pollution from power plants.

A Few are Doing Well: Striped bass and bluefish are voracious predators of smaller fish and shrimp. Spottail shiner, a minnow that feeds on zooplankton and benthic (bottom-dwelling) organisms, is also on the increase.
