These parameters are regression parameters for juvenile Chinook salmon relating Weight to Length where:
The other parameters and algorithm used in the fry growth model is based on Chinook bioenergetic parameters as published by UW Sea Grant Institute, 214 Goodnight Hall, 1975 Willow Drive, Madison, WI 53706-1177 http://www.seagrant.wisc.edu.
Fish bioenergetics technical support is available at bioenergetics web page. The growth of a fish is defined with the following:
where C = consumption, R = respiration, D = SDA, U = excretion,F = egestion, W = weight, V= velocity.
The user selects dr
(prey energy density) and
p (proportion of maximum consumption)
We assume no differences in bioenergetics of juvenile and adult chinook once the fish become fry and have absorbed their yolk sac completely. Although is is possible that the fish can begin eating prior to this point, the overall contribution to growth is small.
Growth in the river is terminated by one of three methods:
