Effectiveness of stocking 7-inch channel catfish to reservoir fisheries

Randy Stewart with a channel catfish from Lone Chimney Lake, Oklahoma.

Duration

January 2010 - December 2013

Narrative

Oklahoma anglers pursue catfish proportionally more than the national average, making up nearly one-half (43%) of the total angling population, making this group of anglers the second-most abundant in the state. Channel catfish are also the third most sought after fish in Oklahoma. As a result, recreational angling for catfish is a top priority for the Oklahoma Department of Wildlife Conservation (ODWC), devoting a significant proportion of hatchery, survey, and management resources toward this activity. We are working to determine the contribution of stocked 7-inch channel catfish to angler catch, harvest, and satisfaction and to overall population structure in 6 medium-sized (500 – 10,000 acres) reservoirs in Oklahoma.
