Scientists to Study CT River Shad Decline
June 28, 2012
Gazettenet.com: The population of American shad in the Connecticut River has plummeted dramatically: Once numbering in the millions, shad counts at the Holyoke dam since 2005 have ranged from 117,000 to 170,000. In 1992, the year that counting began at the dam, 720,000 fish passed through.
Moving up the river, the numbers drop even more, with 80% to 90% declines in the area above the Turners Falls dam and into southern Vermont and New Hampshire.
Biologist Kenneth Sprankle of the U.S. Fish and Wildlife Service and Ted Castor-Santos of the Conte Anadromous Fish Research Center in Amherst want to know why.
