Just for the fun of it eighteen of the participants at last year's ASC in Reykjavík, some of whose daily work involves tagging
fish, wore tags that measured temperature every two minutes over the range of 0_45°C throughout the meeting. The figure gives
the results from the cohort and shows some interesting profiles of activity.
Each participant has received his own temperature profile in the strictest confidence and will doubtless put his own detailed interpretation on it by the hour and the minute. Some made an effort to stress the tags by keeping them in an oven or a refrigerator overnight, but the biggest natural "group signal" appears on the night of the ICES cocktail party. We Homo sapiens, it would appear, are little different from other species when it comes to feeding behaviour, or any other aspect of Life, come to that. But only the individuals concerned can read those other aspects of their records!
