Abstract

1. 1. Patterns of osmoregulation were studied in three species of Swan river atherinids (Leptatherina presbyteroides, lower estuarine and marine; Craterocephalus mugiloides, mid estuarine; Leptatherina wallacei, upper estuarine) over a wide range of salinities. 2. 2. The plasma Na+ concentration was elevated with an increase in salinity. 3. 3. Haematocrit and body water content decreased with acclimation to higher salinity. 4. 4. All three species of atherinids osmotically regulated over a salinity range greater than that which these fish are reported to occur in. © 1992.
