Biological Investigation of Flathead Catfish in the Cape Fear River

Flathead catfish (Pylodictis olivaris) were introduced into the Cape Fear River in 1966 when 11 adult specimens weighing in a total of 107 kg were released near Fayetteville, North Carolina. The population has expanded from this initial release and now inhabits a 201·km section of the Cape Fear River. Growth rates of flathead catfish during this expansion phase has exceeded rates of riverine populations as previously reported by other investigators. Fishes were found to be the dominant forage consumed by flathead catfish as measured by frequency of occurrence, total numbers and total...


Comparison Of Growth Rates And Abundance Of Largemouth Bass In Selected North Carolina Coastal Rivers

Age-growth relationships, length-weight relationships, and relative abundance ind ices were determined for largemouth bass (Micropterus salmoides) collected from the Cape Fear, Chowan, Pasquotank and Tar-Pamlico river systems in North Carolina during 1976. Largemouth bass in the Pasquotank River had the highest mean annual growth rate during their first and second years when compared to those in the other river systems studied. Largemouth in the Tar-Pamlico River system had the highest mean annual growth rates for age groups III and older. The growth rate of the Chowan River largemouth...
