Can a bioenergetics model explain growth of the northeast Arctic cod?
For the period 1984 to 1991, the individual maximum daily consumption in calories (cmax) based on 33000 cod stomach samples is given by the power equation: Cmax = 68.84 · W ^0,934 where W represents the total fish weight in grams. Daily consumption as proportion of individual maximum consumption, la...
