The diel rhythm of emergence from the gravel and displacement downstream has been studied in three salmonoid species: brown trout ( Salmo trutta L.), Atlantic salmon ( S. saiar L.) and grayling ( Thymallus thymallus L.). Grayling emerged in the morning but delayed downstream displacement until the night, while the Salmo species emerged just before downstream displacement chiefly at night.
