Susquehanna River Basin freshwater mussel surveys: 2008-2015

November 21, 2018

Data are included for two types of field surveys conducted for freshwater mussels throughout the Susquehanna River Basin (and one site in the Potomac River Basin) in the Mid-Atlantic region of the United States from 2008-2010. Timed search (qualitative) surveys were conducted in consecutive ~200 meter sections of river (at least 8 in each stream). The number of mussels of each species and associated search time were recorded for each survey section to determine a catch per unit effort (CPUE; number of individuals found per person hour). Within qualitatively surveyed areas, one ~200 meter section of stream was selected in which to conduct quantitative surveys to estimate mussel abundance, assess presence of juvenile mussels, and quantify population demographics. At each survey site, a subset of ~30 Elliptio complanata was haphazardly selected and retained for shell thin-sectioning and age determination. Two sites (Pine Creek and Buffalo Creek) were resurveyed both qualitatively and quantitatively in 2014 and 2015 after experimental re-introduction of the American eel (Anguilla rostrata), a documented host fish for E. complanata.
