Primarily on the basis of Schlieper's data, the conclusion that A. marina is an iso-osmotic osmoconformer has been repeated in later reviews ( Green, 1968; Krogh, 1939; Oglesby, 1969a; Potts and Parry, 1964). How- ever, Belyaev's (1957) results show a stronger degree of hyperosmoticity, by an average of 9% for the Barents Sea population and an average of 12% for the White Sea population, with some data points ranging as high as 24% more concentrated than the medium. There is some difficulty in interpreting Belyaev's.
