Simulated growth potential of redband trout in the Donner und Blitzen River Basin, southeastern Oregon, using a bioenergetics model

Growth potential of redband trout (Oncorhynchus mykiss newberri) was simulated across 175 river segments in the Donner und Blitzen River basin for water years 1980 through 2021 using a bioenergetics model. A previously published framework for assessing climate vulnerability of redband trout was used to simulate the growth potential of redband trout in relation to constraints on body size, physiological responses linked to variable thermal regimes, and variation in physiological adaptive capacity. For body size, three starting sizes of redband trout, 10 g, 50 g, and 150 g, were used for each day of the simulations. For thermal regimes, daily stream temperatures were estimated from PRISM. To account for variation in adaptive capacity, physiological parameters for an average or baseline, cold-adapted and warm adapted individual were used. Growth potential (g/g/day ) for each river segment, body size, and thermal adaptation are provided in the data files provided below.
