Shenango Lake
Mercer County
May 28 - June 2, 2003
Sampling Gear: Night Electrofishing


Shenango Lake is a 3,560-acre U.S. Army Corps of Engineers impoundment located in western Mercer County near Sharon PA. Fisheries Management personnel from the Area One office in Linesville conducted a night electrofishing survey from May 28 to June 2, 2003 to monitor changes in the quantity and size structure of the bass population.

A total of 125 largemouth bass and 142 smallmouth bass were sampled. Largemouth bass ranged in size from 131 mm (5 in.) to 528 mm (20.75 in) with 31% of the fish being over 375 mm (14.8 in). Samllmouth bass ranged in size from 110 mm (4.25 in) to 462 mm (18 in) with 8% of the fish being over 375 mm. This is the first year that more smallmouth bass were caught then largemouth bass. Bass in this lake are managed under the Big Bass Program with a 15-inch minimum size limit and a four fish per day creel limit from June 14 to December 31 (see page 27 in your 2003 Summary Book). Water levels were high this year making electrofishing a challenge.
