Lake Erie -> 2.0 Other Managed Species -> Rainbow Trout

Maintain tributary catch rates for rainbow trout of at least 0.25 fish per hour

Migratory rainbow trout (steelhead; Oncorhynchus mykiss) are an introduced species in Lake Erie that provide localized sport fishing opportunities, primarily during seasonal spawning runs into tributaries. Though limited natural reproduction does occur, annual stocking is necessary to support the rainbow trout fishery in the Lake Erie basin. Annual stocking averages over 1.9 million yearlings with the bulk of the fish planted in the tributaries along the south shore of the lake (Ohio, Pennsylvania, New York; Figure 1). Catch rates (fish per angler hour (fish/hr)) throughout the time-series remain well above the target of at least 0.25 fish/hr and are among the highest in the Great Lakes. Angler survey results found very high angler catch rates in the early and mid-2000’s that averaged 0.60 fish/hr followed by a decline from 2008-2014 (average = 0.35 fish/hr; Figure 2). The most recent survey conducted in 2017-18 in New York tributaries found that catch rates had increased to levels observed in the mid-2000’s.
