Description
Crayfish were surveyed in the Susquehanna River in 2008 and 2013. During each survey 100 baited wire traps were deployed in 10X10 grids at each of 11 sampling sites along 400 km of the river. Rusty crayfish were collected at five of the 11 sites in 2008, and at two additional sites in 2013. The numbers of Rusty Crayfish collected at most sites were similar to 2008. However, at one downriver site in 2013 the number of crayfish collected were astonishing. The high densities of crayfish in this section of the river coincide with reported declines of smallmouth bass.
