Abstract
A model descnbing gashic evacuation developed by dos Santos (1990)
using a modified version of the power exponential model for stomach
evacuation is applied to the Northeast Arctic cod stomachs collected
during 24 hour fishery. An approach to estimate the individual daily
ration that takes into account the effects of initial meal size and fish weight
on gastric evacuation rate in the course of 24 hour veriod is presented.
The results indicate that the Northeast Arctic cod (length groups 40-44
cm and 45-49 cm) during intensive feeding on deep sea shrimp Pandalus
borealis consumed between 0.50 % and 0.58 % of the body weight.
