Trapnet Sample & Night Electrofishing


Lake Arthur is a 3,200-acre lake located within Moraine State Park in Butler County. Fisheries Management personnel from the Area 1 office in Linesville surveyed the fish population with Pennsylvania style trapnets and night electrofishing gear. Four trapnets were set at 16 different locations for a total of 24 sets or 563 hours of trapnet effort. A total of 2,432 fish were sampled representing 16 species.

Channel catfish were the most numerous game fish caught with a total catch of 394 fish ranging in size form 7-28.5 inches. A total of 86 muskellunge was caught, an impressive number. They ranged in size from 29 to 49.5 inches. The northern pike catch was up from nine when the last survey was done in 2004 to 44 in 2007. All the pike were caught upstream of the SR 528 bridge in the eastern part of the lake. Walleye (33) and striped bass hybrids (19) were also collected. Black crappie up to 13.5 inches were caught along with white crappie, bluegill, and pumpkinseed. Some huge carp were also caught with the largest over 36 inches long weighing well over 30 lbs.

Night electrofishing was conducted to sample the black bass population on 3 consecutive nights starting on May 29, 2007. A total of 330 black bass were collected, consisting of 324 largemouth and only six smallmouth bass. The largemouth bass catch rate (number of fish caught per hour of electrofishing) was about 25% higher than the average for the 5 previous sample years starting in 1997. Largemouth ranged in size from 5 inches to 19.5 inches with 23 (7%) of the fish being over 15 inches long. Smallmouth ranged from 6.5 inches to 18 inches long. Several adult striped hybrids were seen along with walleye while electrofishing.
