Senecaville State Fish Hatchery is located on over 120 acres in southern Guernsey County below the dam of Seneca Lake. This facility was acquired from the U.S. Fish and Wildlife Service in 1987. The hatchery has 37 ponds containing a total of 37 water acres and 16 indoor rearing troughs. Water is supplied by Seneca Lake, which can deliver 2,000 gallons per minute. This water supply allows the hatchery to raise saugeye, walleye, hybrid striped bass and channel catfish. Saugeye and walleye production begins in early spring and hybrid striped bass production starts in late spring with fry being grown out to fingerlings at the hatchery. Channel catfish production starts in the summer using breeding adults kept at the hatchery.
