KNOXVILLE — The next round of Conservation on Tap features Conservation Fisheries and its efforts to restore and conserve some of the most diverse fish populations on the planet.
It’s set for 7 p.m. Jan. 10 at Albright Grove Brewing Company, 2924 Sutherland Ave. Proceeds from the event benefit Discover Life in America, a crucial science partner with Great Smoky Mountains National Park.
“Did you know the incredibly diverse Tennessee River harbors over 225 species of fish, including more than 50 species at risk of extinction? Come join staff from Knoxville nonprofit Conservation Fisheries Inc. to learn about CFI's mission to prevent the extinction of rare fish species, and to work for their long-term recovery. We will be discussing some of our successes in fish recovery efforts over the past 37 years, including species found in Great Smoky Mountains National Park.”
Lost and found: The long-awaited return of the robust redhorse
Georgia’s Ocmulgee River is a case study in the decline of Southern river fisheries, and their revival

MACON — The Ocmulgee River has changed. The cloudy water once ran clear. The sandy bottom was once rocky. Fish swam upriver to breed from places as distant as the Altamaha River, which the Ocmulgee and Oconee rivers join to form near Lumber City and the Atlantic Ocean.
European settlement changed the river. Centuries of agriculture and development stripped away much of the land’s vegetation that filtered the flow, causing the Ocmulgee to fill with sediment. The soil particles gradually moved through the waterway, covering gravel that fish spawned in, smothering fishes’ eggs, mucking up the water and even building up on the banks, saturating the ground with sediment.
It is impossible to know how many freshwater fish the Ocmulgee lost since the first Europeans arrived. Many species disappeared without being discovered. Yet on a clear afternoon in May, DNR aquatics biologist Paula Marcinek led a team on the upper Ocmulgee in search of robust redhorse, a “lost” fish found in 1991.
