A common reaction in juvenile salmonids that detect predators is to decrease activity. To test whether there is a survival advanrage to reduced movement under such circumstances, juvenile coho salmon (Oncorbyncbus kisrrtcb) were placed with common mergansers (Mergus merganser) under laboratory conditions that precluded crypsis. Mergansers were more likely to attack fish that moved than fish that remained stationary, and the relation between the lag time for detection by the birds and fish… CONTINUE READING
