dc.description.abstract | 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, laboratory determination of
metabolism, specific dynamic action, activity multiplier and spawning losses were
incorporated into a bioenergetics model to predict growth in energy value for the
Northeast Arctic Cod. Results based on 1990 data indicated that the amount
of assimilated energy (90% of actual fraction of the maximum consumption)
allocated for each components varied according to the season. Highest food
conversion efficiency occurred during the first half of 1990 and declined during
the second half. The annual rates of food turnover were within 20% - 27%
of the annual consumption. Comparisons were made between four cod stocks
concerning the annual energy requirements. | no_NO |
