The value of mangrove ecosystems and the wide variety of useful functions that they perform have been well documented (Turner, 1977; Robertson, 1986; Singh, 1987; Bailey, 1988). For marine fishes especially, and many aquatic organisms, mangrove provide spawning, nursery and forage grounds for post larvae and juveniles (Weistein, 1979; Shenker and Dean, 1979; Robertson and Duke, 1987; Sasekumar et al., 1992). The dependence of juveniles of many marine species on mangrove ecosystems is attributed to their higher productivity as compared to adjacent marine areas (Robertson, 1986). Mc Hugh (1966) estimated that approximately two thirds of commercially important fishes depend on estuarine habitats for the growth of their young. In fact, good correlation has... |

The utilization of an estuarine brackish marsh in the Westerschelde estuary (southwest Netherlands) by fish and crustaceans visiting the intertidal creeks at rising tides was investigated over an 18 mo period. Samples were collected every month over a tidal cycle. A stow net passively fished the nekton migrating in and out of the marsh habitat. Simultaneous measurements of current speed and waterheight allowed for quantification of the catches. Multivariate clustering and ordination techniques were applied to assess temporal changes in the nekton assemblage. A total of 68 fish and crustacean species were caught but only 38 were regular visitors of the marsh creek. The marsh nekton community proved to have a very stable character. Only 40% of the observed... |
