Ohio Division of Wildlife outlines Lake Erie management, invasive carp response and local access funds in Lorain County meeting

Summary
John Navarro, temporarily fish chief for the Ohio Division of Wildlife, described Lake Erie fisheries monitoring, invasive carp risks, telemetry tracking and local access funding — including a planned fish-cleaning station and boat-ramp work for Lorain — and answered questions from residents about stocking and microplastics.
John Navarro, temporarily the fish chief for the Ohio Division of Wildlife, described the agency’s Lake Erie and inland fisheries work and invasive-species response during a presentation at a Lorain County meeting.
Navarro said Lake Erie drives much of Ohio’s fishing activity and that the work includes research, harvest monitoring, stocking and interjurisdictional coordination to sustain sport and commercial fisheries.
Navarro told the meeting that the division runs research units at Sandusky and Fairport, uses gill nets, bottom trawls and electrofishing to track populations, and conducts creel surveys — interviews with anglers at boat ramps — to capture harvest information that helps set regulations and stocking strategies. “Lake Erie is about the size of Vermont,” Navarro said, underscoring the scale of the area the division manages and the need for standardized sampling.
He outlined tools and programs: a new research vessel planned for Sandusky (to be named RV Walleye), hatchery stocking from Ohio facilities, and regionwide coordination through the Great Lakes Fishery Commission, which helps set quotas and coordinates sea lamprey control. The division monitors commercial boats with transponders and requires real-time reporting of catches, Navarro said.
On tracking fish movements, Navarro described the Great Lakes Acoustic Telemetry Observation System (GLATOS) and how tagged fish trigger arrays of bottom-mounted receivers. That data shows seasonal movements and spawning behavior for species such as walleye and lake sturgeon; Navarro said lake sturgeon stocking has succeeded to the point the division will stock the Cuyahoga River in the coming year.
Invasive species drew the most detailed discussion. Navarro said bighead and silver carp are established in the Mississippi River Basin and pose an ongoing risk to the Great Lakes via hydrologic connections such as the Chicago Waterway. He described a local example: a low-lying connection near Lodi that floods annually and can hydraulically link watersheds. The division has completed a high-risk first phase of a rock-berm project on Medina County Park District property to reduce that connection and also plans to top-layer the berm as a birding trail.
Navarro said grass carp present a different challenge: triploid (sterile) grass carp are allowed for vegetation control, but evidence suggests fertile fish released in earlier periods contributed to reproducing populations in Lake Erie. Removal efforts, led in part by the University of Toledo’s seine teams, have grown to 13 teams removing roughly 50 grass carp a year, Navarro said.
On local access and funding, Navarro said the division receives one-eighth of 1% of the state motor-boat gas tax for developing motor-boat access and that the agency is supporting a boat-ramp revitalization in Lorain that will include a fish-cleaning station. He advised municipalities seeking funds for motor-boat access to contact Kurt Wagner, fish management supervisor for District 3, for project guidance; Wagner was identified by Navarro as the District 3 supervisor.
Residents asked about steelhead stocking and environmental review. Navarro said the division is proceeding with a multi-year study and coordination with the National Park Service and local partners to assess potential impacts of stocked steelhead on native species; he noted the program is limited by interjurisdictional agreements and cited a statewide cap on steelhead stocking of about 450,000 fish. He also acknowledged the division is tracking microplastics and other emerging issues and offered to connect residents to the right researchers.
The presentation closed with contact information for local staff and an invitation to visit state hatcheries to see stocking work.
Details provided at the meeting were technical and procedural: the division emphasized monitoring, removal and prevention for invasive species, regionwide coordination through the Great Lakes Fishery Commission and use of state motor-boat gas-tax funds for local access projects such as ramps and fish-cleaning stations.
