Initial relative mass (W(R), low v. high) and energetic trajectory in time (starved v. fed) were experimentally manipulated in bluegill Lepomis macrochirus. Fed fish starting at low W(R) grew more and gained more W(R) than fed fish starting at high W

Relative weight (Wr ) was originally developed to assess the physiological status of largemouth bass. Later it was expanded to other centrarchids and, more recently, to non-centrarchids without consideration of how well the concept may fit other taxa

Physiological status of wild fish is inherently variable in time and space, and investigators need to understand how this variation affects the interpretation of condition indices. Our objective was to describe the relationship of relative weight (Wr

Prey supply to predators is limited by the morphology, behavior, and spatial distributions of both predator and prey. To be eaten, prey must co-occur spatially and temporally with the predator (distribution), the predator must recognize the prey as p

The influence of mode of capture, season of capture and total body length (L T ) on the probability of regurgitation for striped bass Morone saxatilis captured using gillnets in Smith Mountain Lake, Virginia, was examined. Overall. the mean rate of r

Mean annual estimates of the surplus biomass of alewives Alosa pseudoharengus and gizzard shad Dorosoma cepedianum in Smith Mountain Lake, Virginia, were calculated from data on the biomass, growth, and mortality of each clupeid species. Surplus biom

Bioenergetics modeling and estimated population densities were utilized to derive the mean annual food consumption of striped bass Morone saxatilis and largemouth bass Micropterus salmoides in Smith Mountain Lake, Virginia. Mean annual standing stock

Small body size in fall and low winter survival of fingerling striped bass Morone saxatilis stocked into Smith Mountain Lake, Virginia, have been attributed to slow growth during summer months. Although small size at stocking appears to be the primar

First-year survival of striped bass Morone saxatilis stocked into lakes and reservoirs is often poor, but causes of mortality have not been determined. We quantified losses of stocked, age-0 striped bass to predation by largemouth bass Micropterus sa

To explain the limited stocking success of fingerling striped bass Morone saxatilis in Smith Mountain Lake, Virginia, we examined the relationship between size-selective winter survival and length-dependent patterns in growth, food habits, prey fish
