Numerous studies have examined the age and growth of shovelnose sturgeon Scaphirhynchus platorynchus, but only one study attempted to validate age estimation techniques. Therefore, our objective was to use marginal increment analysis to validate annu

The dispersal patterns of 2939 flathead catfish, Pylodictis olivaris (Rafinesque), were determined within a 90-km section of the Missouri River, USA. Fish were captured by electric fishing and tagged in early June each year from 1999 through 2001. Di

The collapse of the European and Asian caviar industry has raised concern about the overexploitation of shovelnose sturgeon Scaphirhynchus platorynchus in the Missouri River. Unfortunately, little is known about the potential effects of harvest on th

We examined tournament records for 1989 through 1998 from the 4F Flathead Club in St. Joseph, Missouri, to determine whether tournament data from catfish (i.e., channel catfish Ictalurus punctatus, blue catfish I. furcatus, and flathead catfish Pylod

We examined differences in angling vulnerability among black crappies Pomoxis nigromaculatus, white crappies Pomoxis annularis, and their naturally produced hybrid offspring in Weiss Reservoir, Alabama, USA, during spring and fall of 1992 and 1993. P

Natural hybridization between black crappie Pomoxis nigromaculatus and white crappie P. annularis recently has been documented in reservoirs of the southeastern United States, including Weiss Reservoir in Alabama. In this study, we examined hybrid zo

Artificial fluctuations in streamflow caused by hydroelectric power dams can degrade fish habitat and reduce the abundance and diversity of riverine fish faunas. Increased minimum water releases and reduced fluctuations in discharge may mitigate thes

We measured species richness, diversity, and abundance of fish in both shallow and deep water areas in regulated and unregulated sections of the Tallapoosa River in Alabama from July 1990 through September 1992 to compare the effects of flow regulati
