The Development of a Respiration Model for Atlantic Salmon (Salmo salar L.): Implications for Conservation

Bioenergetics models can often be used for purposes of habitat quality assessments, habitat restoration and for specific conservation initiatives. An important component of any bioenergetics model is the understanding of how metabolism is affected by biotic (e.g., fish size) and abiotic factors (e.g., temperature). In the context of Atlantic Salmon (Salmo salar L.) conservation, the development of a reliable respiration model can be used alongside estimates of food consumption and growth to further our understanding of anthropogenic-induced impacts (e.g., altered temperature and dissolved oxygen) on the growth and survival of the species. For the purpose of this study, a respiration model for Atlantic Salmon was derived using data gathered from literature that quantified metabolic rates under various conditions. Information on standard and routine metabolic rates in relation to life stage (fry, parr, smolt, adult), body mass (0.1 - 8,849.5 g), water temperature (1.0-24.0°C) and salinity (0-35 ppt) were obtained from 30 studies. Most data available pertained to juvenile life stages, inferring a lack of information for adult and wild Atlantic Salmon. This model will be useful for future bioenergetics application where threats to the survival of Atlantic Salmon are being addressed.
