Using meta-analysis to derive a respiration model for Atlantic Salmon (Salmo salar) to assess bioenergetics requirements of juveniles in two Canadian rivers
Standard metabolic rates (SMRs) for Atlantic salmon (Salmo salar) have been calculated independently for different life stages and populations, but the absence of a comprehensive SMR model limits its application for modelling the energy use or life stage-specific growth. Atlantic salmon respiration...
