Linear Ranges of Large Flathead Catfish in Two Mississippi Streams
Radio telemetry and mark-recapture techniques were used to monitor linear ranges of large (TL > 510 mm) flathead catfish {Pylodictis olivaris) in the Big Black River and the Tallahatchie River, Mississippi. Linear ranges of transmitter-tagged fish averaged 0.75 km (SE = 0.09 km, N = 6) in the Big Black River and 1.04 km (SE = 0.13 km, N = 8) in the Tallahatchie River. In the Big Black River, 116 adult flathead catfish were tagged with Floy T-Bar anchor tags. There were 6 recaptures from the Big Black River with all recaptures occurring <2 km from release sites.
