Re-estimating temperature-dependent consumption parameters in bioenergetics models for juvenile Chinook salmon
John M. Plumb, Christine M. Moffitt
2015, Transactions of the American Fisheries Society (144) 323-330
Researchers have cautioned against the borrowing of consumption and growth parameters from other species and life stages in bioenergetics growth models. In particular, the function that dictates temperature dependence in maximum consumption (Cmax) within the Wisconsin bioenergetics model for Chinook Salmon Oncorhynchus tshawytscha produces estimates that are lower than those measured in...
