Notes:
We developed a generalized bioenergetics model following the methods described by Mangel and Satterthwaite (2008) and parameters described by Rand et al. (1993) for steelhead trout in the great lakes. According to this model, growth is defined as the difference between anabolic gains (i.e. consumption) and catabolic losses (i.e. energy lost through respiration). Factors affecting growth in our model include stream temperature, food availability, fish density, and fish size. According to our current growth model, growth peaks at 20 degrees C and then declines sharply. The model can be easily modified to explore different assumptions concerning optimal growth temperatures or food availability.
