The rise in activity from 16-18 to 18-20 hrs. and from 22-00 to 00-02 hrs. was significant (P<), as was the decrease from 00-02 to 04-06 hrs. (two time intervals seen together) (Fig. 3). The activity period of the animals at this time of year was clearly longer than the activity measured in summer, as was the period of darkness (<5 lux), which lasted from approximately to hrs. The aquarium study in June 1995 confirmed the results of the field investigations, although there were minor deviations, probably for methodological rea- sons. Activity was negligible until 21 hrs. when a rise in activity occurred resulting in a peak at 21-23, 23-01 or 01-03 hrs. (Fig. 4). In the more detailed aquarium investigations on 20 June, the activity started about 15 minutes before the 5-lux limit was reached in the open. However, since the aquarium was partially covered (see Methods), the.
