Table 1. Mean body mass for each age cohort of northern pike found in the Ouray reach of
the Green River. Predicted consumption rates in the bioenergetics model were fitted to growth
from the mean (2SE) body mass estimates on 1 May, 1993 (simulation day 1), 29 October,
1993 (simulation day 182), and 30 April, 1994 (simulation day 365).
