Flathead catfish (Pylodictis olivaris) status data created for the Western Division of the American Fisheries Society (WDAFS)
Survey data was integrated within a GIS by georeferencing observations to an existing national spatial framework (National Hydrography Dataset), which allows for broader transferability to watersheds shared with neighboring states, creating a seamless layer not limited by state boundaries. Addressing the management and conservation challenges for native fishes will require the ability to “data mine” the extensive existing information on distribution and abundance of species available from aquatic survey programs. Results from such syntheses can be used to assess the current conservation status of native fishes, quantify the extent of species invasions, and establish baseline distributions with which to evaluate...
Population genetic data for flathead catfish from the Susquehanna and Delaware River basins in Pennsylvania and Maryland, USA
This dataset includes microsatellite genotypes for 137 flathead catfish from the Susquehanna River and Delaware River basins in Pennslyvania and Maryland, USA. Each individual was genotyped at 13 loci. Additional information about sex, capture date, and size are also provided for most individuals.
These data were compiled to evaluate the potential impact various environmental conditions may have on native fish populaitons through predation. Introduced warm-water sport fishes present a high predation risk for juvenile native fishes, but observations of juvenile native fish surviving and recruiting in some rare cases led us to question what environmental conditions might be responsible for these trends. These data were compiled to allow for a relative comparison of predation effectiveness between a suite of warm-water predators under a variety of environmental conditions. Mean numbers of prey fish surviving in replicated overnight laboratory predation trials were quantified.
