Abstract
For wild fish populations, predation is an ever present threat. In consequence fish have developed a range of morphological devices and behavioural strategies to reduce their risk of becoming prey. This risk however, may not be constant and may change significantly for individuals of many species over short time spans, depending on the activities that the individual is engaged in. Investigations into the conflict that occurs between the need to perform some high risk activity and the need to avoid being preyed upon, have focused almost exclusively on laboratory studies of the relationship between foraging and the risk of predation in individuals (Milinski & Heller, 1978; Milinski 1984, Metcalfe et al. 1987a, 1987b) and there is a paucity of data relating to natural populations and on the predation risk of activities other than feeding.
