The Development and Application of a Larval Pallid Sturgeon (Scaphirhynchus albus) Bioenergetics Model
… the objective of this study was to develop a bioenergetics model to determine optimal temperature for growth of young-of-year Pallid Sturgeon and apply the model in a realistic simulation. To develop this model, I estimated metabolic demands and growth over a range of temperatures and sizes. …

Analysis of the impact of flathead catfish predation on the abundance of four centrarchid species
… dolomieu, and spotted bass M. punctulatus. A bioenergetics model was used to estimate the number of age-l and older centrarchids consumed annually by the flathead catfish population. These estimates were then compared to estimated abundances of each centrarchid species (age-1 and older) in the …

Development and Application of a Spatially-explicit Model for Estimating Growth of Age-0 Pallid Sturgeon in the Missouri River
… were to 1) parameterize and evaluate a foraging model for age-0 Pallid Sturgeon, 2) evaluate the critical and lethal temperature maxima for Pallid and Shovelnose Sturgeon (Scaphirhynchus platorynchus) of different sizes and acclimated to different temperatures, 3) evaluate the performance of a …

Food habits, population dynamics, and bioenergetics of four predatory fish species in Smith Mountain Lake, Virginia
… at densities of 8.2 and 2.0/ha, respectively. A bioenergetics model was developed for striped bass and, with models developed for walleye and largemouth bass, used to estimate annual consumption of alewives and gizzard shad by the four piscivorous species. Annually, striped bass consumed the …

Contemporary Assessment of Benthic Macroinvertebrates and Fish Interaction in the Truckee River, NV
… macroinvertebrates were examined. A linear mixed model was utilized to determine relationships between water quality parameters and macroinvertebrate communities. Results suggest the biomass and abundance of macroinvertebrates is related to seasonal influences, where these measurements were much …

Bioenergetics of Rainbow Trout in Lake Oahe, South Dakota
… The objective of this study was to modify the bioenergetics model developed by Hewett and Johnson inorder to determine the total consumption of rainbow smelt by the rainbow trout population in Lake Oahe, South Dakota. Rainbow trout were sampled with monofilament gill nets set on the bottom, …

Influence of Feeding History on Metabolic Rates in Fishes: Evidence for Metabolic Compensation in Largemouth Bass (Micropterus salmoides)
… effects are generally not incorporated into fish bioenergetics models (BEM) to estimate metabolism. As a result, the accuracy of bioenergetics models can be hampered because of incomplete parameterization of the model. Moreover, efforts to synthesize information about factors affecting fish …

Overwintering abundance and distribution of striped bass (Morone saxtilis) in the Hudson River estuary using hydroacoustic techniques
… of striped bass was then entered into a bioenergetics model for the purposes of examining the effect of striped bass populations on the various Alosa populations in the Hudson River. Of primary interest was the affect of increasing striped bass numbers on already dwindling American shad …

Habitat Mapping and Predator-Prey Dynamics in Ohio Resevoirs
… a spatially explicit growth rate potential (GRP) model. Using a saugeye bioenergetics model, we combined spatially referenced prey biomass and water temperature to determine potential growth of saugeye during the months of April - October. Overall, we found that GRP was low in the spring, before …

Effects of seasonal habitat limitations on the distribution and energetics of stocked salmonids in Lake Moomaw, Virginia
… on the growth of age 2+ trout in Lake Moomaw. A bioenergetics model predicted that even brief durations of isolation from prey could severely limit the growth of age 2+ brown and rainbow trout.

Atlantic sturgeon growth responses to dual seasonal spawning, latitudinal thermal regimes, and Chesapeake Bay environmental stressors
… Performance of a principal Atlantic sturgeon bioenergetics models was evaluated first by describing trends in habitat suitability during a recent 20+ year span in the Chesapeake Bay, and then by testing model predictions against incidence data for an abbreviated period which included 1562 …

Influence of Rainbow Smelt Predation on Zooplankton Community Composition in Lake Oahe, South Dakota
… 10.1°C. These data will be incorporated into a bioenergetics model for rainbow smelt inhabiting Lake Oahe, South Dakota.

Bioenergetics of Walleye in Lake Oahe, South Dakota
… need to be considered in energetics studies. A bioenergetics model developed for walleyes in Lake Oahe was used to estimate predation on rainbow smelt, the primary forage species in the reservoir. Model estimates indicated that ages 1-6 walleyes in Lake Oahe would consume most of the rainbow …

Life History and Bioenergetics of Chinook Salmon in Lake Oahe, South Dakota
… 62% for age-0 salmon to 4% for age-3 salmon. A bioenergetics model developed for chinook salmon in Lake Oahe was used to estimate predation on rainbow smelt. Modeled chinook salmon growth estimates were usually within ± 1 standard deviation of the measured monthly weights for chinook salmon …

Advanced Largemouth Bass Production and Stock Contribution to Small South Dakota Impoundment Fisheries
… to predict consumption or growth using fish bioenergetics models could further reduce per unit production costs by maximizing feed utilization and decreasing costs associated with excess feed including nutrient loading, sedimentation, and water quality. Fish bioenergetics models have been …

Factors Affecting Mercury Accumulation in South Dakota Fishes
… the following objectives: 1) develop empirical models for predicting Hg concentrations in South Dakota fishes; 2) quantify seasonal and gender-related in Hg concentration of walleyes Sander vitreus; 3) evaluate relationships between Hg concentration and reproductive condition of walleye; and 4) …
