Abstract

We describe the use of flume nets for passively, quantitatively, and nondestructively sampling fishes and macrocrustaceans on tidal marsh surfaces. We captured 3,765 organisms of 23 species in 118 samples using six such nets in a Virginia tidal freshwater marsh in 1984. Efficiency estimates for four common species of fishes range from 53 to 80%. Flume nets are most suited to the collection of long-term data and are particularly useful in elucidating seasonal trends in species composition and relative abundance. These nets are also useful in comparing different microhabitats within and between marshes. This method is most applicable to intertidal habitats with predictable lunar tides, including mud flats, mangrove swamps, and other wetlands.
