Summary This report demonstrates that captured wild North Atlantic cod (Gadus morhua) adapt rapidly to experimental starvation conditions and also appear to tolerate absence of food during the 16 week experimental period at temperatures of 8–10 °C. Our work builds upon and confirms scattered findings in the literature that cod and other gadoids are well adapted to tolerate periods of absence of food. Further, cod seem to rapidly recover muscle mass and energy reserves when offered food after a period of feed restriction. In our experiments, where cod were starved over a 12 week period, we revealed some differences in blood plasma ions and glucose concentrations between groups of starved and fed cod. The differences, though they are minor, might indicate that food restriction challenged the osmoregulation of plasma ions. The responses are sub-lethal and do not cause increased mortality in the feed restricted groups.
