October 29, 2014 – Dr. Brian Mangan, director of the Environmental Program and professor of environmental science and biology at King’s College, has received a $63,800 research grant from PA Sea Grant to expand his study of crayfish in the Susquehanna River and to develop a reliable method for measuring crayfish density in large streams and rivers.
Along with colleagues from Boston University, Bucknell University, and Susquehanna University, Mangan will investigate the diet of crayfish in the river and, in particular, that of the invasive rusty crayfish.
In 2008 and 2013, Mangan and his King’s students documented the crayfish species and their relative abundances along 400 km of the river from the New York border to just north of Harrisburg. Within that same time period, numbers of smallmouth bass in middle sections of the river began to decline. Mangan will investigate if the rusty crayfish are contributing to the bass decline.
