Relative Weight (Wr) Status and Current Use in Fisheries Assessment and Management
Condition assessment is commonly practiced by fisheries personnel as one tool for evaluating fish populations and communities. Several noninvasive condition measures are available for use, includingExpand

Density-Dependence and Environmental Conditions Regulate Recruitment and First-Year Growth of Common Carp in Shallow Lakes
Abstract Recruitment dynamics of fishes can determine their abundance and subsequent effects of adult populations on ecosystem properties. Common Carp Cyprinus carpio is a widespread invasive speciesExpand

Trophic ecology of largemouth bass and northern pike in allopatric and sympatric assemblages in northern boreal lakes
Largemouth bass (Mieropferus salmoides) and northern pike (Esox lucius) are top predators in the food chain in most aquatic environments that they occupy; however, limited infonnation exists onExpand

Simulated Population Responses of Common Carp to Commercial Exploitation
Abstract Common carp Cyprinus carpio is a widespread invasive species that can become highly abundant and have deleterious ecosystem effects. Thus, aquatic resource managers are interested inExpand

Relationship of relative weight (Wr) to proximate composition of juvenile striped bass and hybrid striped bass
Abstract The relative weight (W r ) index is commonly used to assess fish condition. However, little is known about the relationship of W r to physiological condition. Whole-body proximate analysisExpand

Standard Weights (Ws ) for Striped Bass, White Bass, and Hybrid Striped Bass
Abstract We developed relationships between standard weight (Ws , g) and total length (TL, mm) for striped bass Morone saxatilis, white bass M. chrysops, and palmetto bass M. saxatilis ♀ × M.Expand

Temporal food web variability in an upper Missouri River backwater: energy origination points and transfer mechanisms
– Energy transfer mechanisms often cannot be identified with either an isotope or a food habits analysis; however, a combined assessment provided collaborative support for depicting backwater foodExpand

Relationships among invasive common carp, native fishes and physicochemical characteristics in upper Midwest (USA) lakes
Common carp Cyprinus carpio is a widespread invasive species that, in high abundance, can impose numerous deleterious effects in aquatic ecosystems. Common carp increase turbidity and nutrientExpand

Behavioral Responses of Rainbow Smelt to in situ Strobe Lights
Abstract We conducted in situ testing of strobe lights as a potential fish deterrent by examining avoidance and acclimation behaviors of rainbow smelt Osmerus mordax in Lake Oahe, South Dakota.Expand

Physicochemical and Biological Influences on Black Bullhead Populations in Eastern South Dakota Glacial Lakes
ABSTRACT Lake and fish survey data (1991–1992) were compiled for 23 eastern South Dakota natural lakes to provide a basis for preliminary investigation of black bullhead (Ameiurus melas) populations.Expand
