For light-adaption we subjected five fish to a light intensity of 50 and removed one fish at intervals of 15, 30, 60, 120, and 180 minutes after the natural seasonal time of sunrise (0630 hr.). Our procedure was as follows: we removed a fish at random from an aquarium, immediately decapitated it, punctured the cornea and fixed the head in Held's solution. This procedure took less than one minute. For fish sampled under darkness, we performed t
