Use of Shadow Bass Stock Characteristics to Evaluate Natural and Scenic Waterways in Mississippi

Shadow bass (Ambloplites ariommus) stocks were characterized in the Yockanookany and upper Pearl Rivers (1994-1996) to determine if this relatively uncommon fish could be used to evaluate streams for inclusion in the Mississippi Natural and Scenic Waterways System. Habitat influences (e.g., negative effects of channelization) on shadow bass were best reflected in stock characteristics that need considerable data and laboratory work (i.e., age and growth studies, condition factor analysis). Such studies focusing on shadow bass are incompatible with programs requiring rapid assessments of...
