Tuscarora Lake
April 10, 2003
Sampling Gear: Night Electrofishing


On April 10 biologists from the Pennsylvania Fish and Boat Commission’s (PFBC) southeast region office, assisted by Waterways Conservation Officers, conducted a night electrofishing survey of Tuscarora Lake. The purposes of the survey were two-fold: 1) to evaluate the fingerling walleye stocking program and 2) to evaluate the effects of annual lake drawdowns designed to reduce the yellow perch spawning success, reduce the total number of yellow perch in the lake, and increase their average size.

During 1 hour and 53 minutes of electrofishing PFBC biologists collected 3 walleye (14”, 28”, and 30” long), 28 yellow perch (3 - 12 inches long), 14 chain pickerel up to 23 inches long, and 47 trout up to 17 inches long. The catch of all fish species was less than expected and was most likely the result of lower than average spring water temperatures. The water temperature at the time of the survey was 46F. The yellow perch population size structure appeared to have improved with larger fish being present. The improvement was probably the result of the lake drawdowns aimed at reducing perch spawning success and the establishment of a substantial reproducing shiner population initiated through PFBC stockings. The abundance of trout indicates that as in the past a number of fish remained in the spring following fall stocking despite fall and winter fishing pressure. The lake provides “opening day” fishing without the need for a spring stocking and without crowded angling conditions.
