JRSR: Did you catch oodles of cats? I ask only because an acquaintance of mine wrote the PAFBC inquiring about options that may be implemented to reduces the catfish population as it seems to have exploded the last few years. Long story short, a biologist named Timothy Wilson responded stating that netting samples revealed that there are more walleye in the lake than cats. I find that near impossible to believe as I have fished the lake 3 times this year and caught roughly 4 dozen cats without a single walleye. When the total fish caught by the three of us that fish the lake from a boat is totaled, it's roughly a gross of cats and ONE WALLEYE.
Dear Mr. Clarke,
Spring water temperatures in the mid-60s are within the preferred temperature ranges of almost every fish in the lake. They are all at or near their peak activity levels having just completed spawning (Walleyes, Perch and Musky) or are about to spawn (Crappies, Bluegills, Bass and Catfish).
The Fish and Boat Commission has not stocked Channel Catfish in Pymatuning Reservoir since 1995. Their abundance is determined through natural reproduction, natural mortality (predation, disease, etc. .) and angler mortality (harvest). Our only methods of control are increasing the abundance of predators of juvenile Channel Catfish and promoting the harvest of Channel Catfish by anglers. The predator population in Pymatuning is very dense, however, so are the prey populations of Alewives, Gizzard Shad and Spottail Shiners, so predation on juvenile Catfish isn't likely to change much. We allow unlimited harvest of Catfish, we promote the fishery to anglers whenever possible and encourage them to harvest and eat Catfish. Angler harvest is the best method of reducing Channel Catfish abundance.
We just completed our annual survey of Pymatuning Lake and yes, Channel Catfish are abundant. However, each of the following species is more abundant than Catfish; Walleyes, Black Crappies, Yellow Perch, Bluegills and Largemouth Bass.
Finally, if you aren't catching your target species, I would recommend a change in fishing tactics. A change in location, bait, depth, speed, etc.. will likely produce a change in the species you are catching. Personally, my first fishing trip to Pymatuning was April 18th. Using minnows, I caught my limit of Crappies, a couple of Perch, a couple of Bluegills, a small Largemouth Bass and only 2 Catfish in 3 hours of fishing after work. When fishing for Walleyes with night crawlers, I make sure the boat is drifting quickly (i.e. a Walleye chop on the water) or else I catch more Catfish, Bluegills and Perch than Walleye.
I'm sorry you don't like the Catfish fishery in Pymatuning Lake, but their abundance is determined through natural processes and we want them as part of the fishery because we have anglers that do like them.
