Abstract

Four species of Cliona have been identified in Louisiana oyster shells: C. celata Grant, C. lobata Hancock, C. vastifica Hancock, and C. truitti Old. These differ in tolerance to low salinity and may be used as salinity indicators. A tentative division of Louisiana estuarine waters into 6 zones is made on the basis of presence or absence and relative abundance of C. truitti (low salinity species) and C. celata (high salinity). The zones correspond to differences in frequence of low salinities, as shown by daily or continuous salinity records over periods of one year or more.
