How many steelhead does Ohio stock each year?
Ohio stocks approximately 450,000 yearling steelhead per year into seven Lake Erie tributaries. The target allocation breaks down as: Chagrin River 80,000, Rocky River 80,000, Grand River 80,000, Cuyahoga River 60,000, Conneaut Creek 50,000, Ashtabula River 50,000, Vermilion River 50,000. All are Little Manistee strain, raised at the Castalia State Fish Hatchery, stocked in April–May after yearlings reach 7–9 inches.
The 450,000 annual yearling target represents ODNR's standard stocking capacity. The allocation is distributed across seven Lake Erie tributaries, expanding from the historic five-river footprint to include active programs on the Cuyahoga River and Ashtabula River. The 'Big Three' (Chagrin, Grand, and Rocky) receive the largest share at 80,000 smolts each due to their high angler capacity and extensive public parks. The Cuyahoga receives 60,000, while Conneaut, Ashtabula, and Vermilion receive 50,000 each. Smolts are released in late spring and head straight to Lake Erie, returning as mature fish after two to three seasons of growth in the lake.

FAQ
Why don't Black River or Huron River get stockings?
Both face habitat limitations. The Black River has legacy industrial pollution and low gradient, while the Huron River is smaller with fewer cold-water inputs. ODNR prioritizes tributaries that offer the highest angler returns and water quality.
Does the allocation change year-to-year?
Minor variations occur based on hatchery survival rates and egg collection success, but the target 7-tributary distribution (450k target total across Ashtabula, Chagrin, Conneaut, Cuyahoga, Grand, Rocky, and Vermilion) remains stable.
Where can I see the official stocking schedule?
ODNR publishes annual stocking summaries on their website and announces the stocking schedule in early spring, typically around March.
