Resident Fisheries Study Lower Susquehanna River, Maryland

摘要

The life history and distribution of resident fishes in the Lower Susquehanna River below Conowingo Dam were studied from June 1980 to February 1981. Schnabel population estimates revealed the predominant species, in order of abundance, were: white perch, channel catfish, carp, and yellow perch. Catch per unit effort (CPUE) data indicated that fish abundance progressively decreased from the dam to the farthest downstream transect with significant differences for gizzard shad, channel catfish, and all species combined during the summer period. Gizzard shad displayed a significant increase in CPUE from spring to fall.
