Abstract
The purpose of this study was to characterize marsh use by fishery species relative to salinity regime. Several hypthoseses were proposed. The central hypothesis was that marshes in the mid-range salinity regimes are more utilized by the estuarine aquatic fauna than marshes in low or high salinity regimes. Subhypothes proposed, a) that habitats with mid-range salinities have higher densities of fishery organisms, and b) that habitats with mid-range salinities have greater abundances of foods foraged by juveniles of fishery species.
