Salinity Preference in Corophium Volutator

Abstract
It has been suggested (McLusky, 1968 a) that migrations of Corophium volutator (Pallas) may occur in response to salinity. This suggestion was based on distributional evidence from the estuary of the River Ythan, Aberdeenshire, and assumed that the animals are able to detect salinity and exhibit a behavioural response to it. The presence and nature of such a response has been investigated by means of choice experiments. Burrowing, swimming and feeding behaviour of C. volutator have been studied by Meadows & Reid (1966) and Morgan (1965).
