The estuarine clams Katelysia rhytiphora (Lamy) and Tapes dorsatus (Lamarck) require salinities of 20–45% 0 for survival and of 25–35% 0 and 30–40% 0 respectively for best growth. The highest 24‐h algae clearance rates for K. rhytiphora and T. dorsatus were observed at salinities of 25–35% 0 and 30–35% 0 respectively. Neither species survived longer than 7 days at salinities <20% 0 and they can. therefore, only be grown in the high‐salinity parts of estuaries. The salinity requirements of these clams should be a primary consideration when selecting farming sites. Other species of bivalves that tolerate lower salinities should also be considered for farming in brackish water areas of New South Wales, Australia.
