Fall Walleye Young-of Year Survey
September 27, 2008

On September 27, 2008 crews from both the Ohio Division of Wildlife and the Pennsylvania Fish and Boat Commission conducted a night electrofishing survey on Pymatuning Reservoir. A young-of-year (YOY) abundance survey is performed annually to monitor survival of walleye stocked into the lake. Walleye fry stockings have proven successful in the past at Pymatuning, supporting healthy year classes throughout the 90s. However, in recent years, fall walleye YOY survey results have been poor indicating poor survival from fry stockings.

In 2008 the two states agencies decided to not only stock 4 million 1/4 inch long walleye fry from the Linesville Hatchery, but to also stock walleye fingerlings. Each state was able to raise and stock just over 290,000 one inch long walleye fingerlings. These fish were stocked in late May and early June.

Catches this fall averaged 0.56 YOY walleye per minute of electrofishing, the best catch rate since 2000. The catch this autumn was a big improvement over the 0.028 fish per minute found in 2007 and the 0.13 fish per minute found in 2006. The YOY walleye this fall averaged 204 mm, or about 8 inches. The 2008 year class should reach the minimum size limit of 15 inches by the spring of 2010. If possible we plan to continue supplemental stocking of walleye fingerlings for next few years. Both state agencies are committed to providing a quality walleye fishery at Pymatuning Reservoir.
