1573 ARTICLE Temperature regimes, growth, and food consumption for female and male adult walleye in Lake Huron and Lake Erie: a bioenergetics analysis Charles P. Madenjian, Todd A. Hayden, Tyler B. Peat, Christopher S. Vandergoot, David G. Fielder, Ann Marie Gorman, Steven A. Pothoven, John M. Dettmers, Steven J. Cooke, Yingming Zhao, and Charles C. Krueger Abstract: Bioenergetics modeling was used to assess the relative importance of food availability and water temperature in determining walleye (Sander vitreus) growth. Temperature regimes experienced by both female and male adult walleye in three basins of Lake Huron and in Lake Erie were determined by use of surgically implanted temperature loggers and acoustic telemetry. Temperatures experienced by walleye were higher in Lake Erie than in Lake Huron. Walleye from Lake Erie grew at nearly double the rate of walleye from Lake Huron, and mass at age for adult females averaged about 50% greater than that for adult males in both lakes. Food consumption rate for an average adult walleye in Lake Erie was nearly twice as high as that in Lake Huron. Interbasin and interlake variability in temperature regimes accounted for a moderate degree of variability in walleye growth. We concluded that the driver for faster growth in Lake Erie compared with Lake Huron was higher food availability in Lake Erie compared with Lake Huron. The sex difference in temperature regimes explained 15% of the sex difference in Lake Erie walleye growth. Résumé : La modélisation de la bioénergétique a été utilisée pour évaluer l’importance relative de la disponibilité de nourriture et de la température de l’eau comme facteurs déterminants de la croissance des dorés jaunes (Sander vitreus). Les régimes thermiques auxquels sont exposés les dorés adultes femelles et mâles dans trois bassins du lac Huron et dans le lac Érié ont été déterminés en utilisant des enregistreurs de température implantés chirurgicalement et la télémétrie acoustique. Les tempéra- tures étaient plus élevées pour les dorés dans le lac Érié que pour ceux dans le lac Huron. Le taux de croissance des dorés du lac Érié était presque le double de celui des dorés du lac Huron, et le poids en fonction de l’âge pour les femelles adultes était en moyenne 50 % supérieur à celui des mâles adultes dans les deux lacs. Le taux de consommation de nourriture pour un doré adulte moyen dans le lac Érié était presque deux fois plus grand que dans le lac Huron. La variabilité des régimes thermiques entre bassins et entre lacs explique un degré modéré de variabilité de la croissance des dorés. Nous concluons que le facteur expliquant For personal use only. la croissance plus rapide dans le lac Érié que dans lac Huron est une plus grande disponibilité de nourriture dans le lac Érié. La différence entre les sexes sur le plan des régimes thermiques explique 15 % de la différence entre les sexes sur le plan de la croissance des dorés du lac Érié.

A fish bioenergetics model represents an energy budget for basin (Hayden et al. 2014). Walleye remaining in Saginaw Bay are a fish.

The primary goals of our study were to compare walleye growth where C = consumption, R = standard metabolism, A = energy in Lake Huron with walleye growth in Lake Erie and to assess the expenditure due to activity, SDA = specific dynamic action (energy relative importance of food availability and temperature regime required to digest food), F = egestion, U = excretion, and G = growth. as determinants of walleye growth in the Lake Huron – Lake Erie Standard metabolism is typically modeled as an exponential func- system.
