Overall, we counted 109 trout in the daytime and 333trout at night. We speculate that trout counted at night were presentduring the daytime but were hidden from view. Biologists should considerthat trout behavior and visibility might vary between daytime and night,even during summer. In some streams, the majority of trout may not beseen during the daytime."
