Relationship between Discharge and Electrofishing Catch-per-unit-effort of Largemouth Bass in the Neuse River, North Carolina

Sportfish managers in coastal North Carolina are often challenged with interpreting estimates of largemouth bass (Micropterus salmoides) relative abundance (catch-per-unit-effort, CPUE) due in part to the influence of environmental factors on boat electrofishing techniques. To accurately assess population abundance using relative abundance indices, the effects of environmental variables on largemouth bass catch should be quantified. We sampled largemouth bass populations in Neuse River tributaries weekly in spring 2006 and 2007 to investigate the relationship between CPUE and...

Investigating Striped Bass Recruitment in the Neuse River, North Carolina

Investigating trends in striped bass (Morone saxatilis) juvenile abundance is important for determining which factors may affect recruitment. We evaluated the abundance and distribution of juvenile striped bass in the Neuse River from 2006-2007 using beach seines and electrofishing techniques. Overall, little evidence of recruitment was found. Juvenile striped bass were not documented in the system during summer 2006 and were collected in low densities from isolated areas (2 of 34 sample sites) during summer 2007. Because catch was low, we could not adequately describe nursery habitat...
