Population Dynamics of Introduced Flathead Catfish in Two Atlantic Coastal Plain Rivers Under Differing Management Strategies

SEAFWA Journal Volume 3, March 2016

We described and compared population dynamics of introduced flathead catfish (Pylodictis olivaris) between the Satilla River, Georgia, and the Little Pee Dee River, South Carolina. Both of these Atlantic coastal plain rivers are blackwater, low productivity systems that historically supported popular redbreast sunfish (Lepomis auritus) fisheries. Flathead catfish have been established in the Little Pee Dee River since the late 1970s or early 1980s, whereas the species was introduced into the Satilla River in the mid 1990s. Both populations are managed differently by their respective state...


Comparison of Growth, Abundance, and Emigration of Two Morone Hybrids in a High Flow-through Oklahoma Reservoir

SEAFWA Journal Volume 1, March 2014

Hybrid striped bass (Morone saxatilis x Morone chrysops) are commonly introduced in southeastern U.S. reservoirs to create a sport fishery and as a means of utilizing abundant shad (Dorosoma spp.) populations. The Oklahoma Department of Wildlife Conservation (ODWC) has historically stocked the common-cross hybrid (M. saxatilis female x M. chrysops male; hereafter, common HSB) rather than the reciprocal-cross hybrid (M. saxatilis male x M. chrysops female; hereafter, reciprocal HSB). Due to concerns over downstream emigration of stocked fish from reservoirs, common HSB have mostly been...
