Young-of-the-year Walleye Survey
Bucks County
November 3, 2003

Sampling Technique: Night Electrofishing

On November 3, 2003 biologists from the Pennsylvania Fish and Boat Commission’s (PFBC) southeast Area 6 region office conducted a night electrofishing survey of Lake Galena to sample young-of-the-year walleye. The survey was conducted to determine the extent of walleye natural reproduction occurring in Lake Galena.

In two hours of electrofishing approximately one-half of the lake’s shoreline was electrofished with no young-of-the-year walleye being collected. A total of one young-of-the-year walleye was collected during similar surveys conducted in 1991, 1993, and 1994. The results from these surveys provide clear evidence that walleye reproduction alone is insufficient to maintain the walleye population in Lake Galena. Annual stockings of walleye fingerlings are required to maintain the current population density and support the walleye fishery. Walleye fingerlings have been stocked annually since 1992 and will continue to be requested for stocking.

Other fish species encountered during the 2003 young-of-the-year walleye survey included white perch, black crappie, and yellow perch. One 17 inch walleye and numerous quality largemouth bass were also collected. Results from the spring 2003 Lake Galena survey are available under Area 6 Reports.
