“…Their ability to enter the lower river, with its more abundant predators (Mulkana, 1966), enables them to feed on epibenthic prey in and around eelgrass (Zostera) beds when zooplankton abundance declines in late summer and fall (Bengtson, 1982). Large size would be a further advantage in late fall and winter when M. menidia moves into deeper, offshore waters (Richards and Castagna, 1970;Conover and Murawski, 1982). Judging by the emaciated appearance of Atlantic silversides when they return to the estuary in spring, the fish probably metabolize their body tissues during the winter.…”

Resource overlap values were calculated for habitat and food utilization by Menidia menidia and M. beryllina in 2 Rhode Island estuaries (USA). Habitat overlap was nearly complete during spring, but declined during summer and fall. Food overlap varied greatly throughout the year. The 2 species coexist because they: (a) overlap strongly in both food and habitat utilization only when food is abundant, and (b) have evolved different spawning times and different growth rates. M. menidia grows to a larger body size than M. beryllina and can utilize different habitats and foods when zoopla.nkton becomes scarce. Time of hatching of each species in the upper estuary was related to cycles of zooplankton abundance M. menidia larvae probably have a substantial predatory impact on zooplankton In the upper estuary during June of each year.

“…The lagoon systems off Virginia's Eastern Shore are subject to large fluctuations in temperature typical of most MAB systems (0-30°C), but they differ from larger estuaries in that they are shallow (mean depth <3 m), well-mixed, and polyhaline areas. These lagoon systems are a nursery ground for juvenile Summer Flounder (Schwartz, 1964;Norcross and Wyanski, 1994;Desfosse, 1995;Kraus and Musick, 2001), hut they also support a large number of adults and an active recreational fishery (Richards and Castagna, 1970). Previous descriptions of the use of our chosen lagoon system by Summer Flounder have been limited to descriptions of juvenile habitat preferences (Wyanski, 1990;Norcross and Wyanski, 1994) and adult migration patterns determined by traditional mark-recapture methods (Kraus and Musick, 2001;Desfosse, 1995).…”

“…To capture representative tidal creek assemblages, surveys were conducted during the time of the year when abundance and diversity are generally highest in temperate estuaries (e.g., Richards and Castagna 1970;Hoff and Ibara 1977;Rountree and Able 1992). Each gear type selects for various components of a fish community in a given location.…”

Response of Tidal Creek Fish Communities to Dredging and Coastal Development Pressures in a Shallow-Water Estuary

To investigate the effects of dredging and associated development pressures (i.e., shoreline armoring, developed land use) on fish, three sets of paired dredged and undredged tidal creeks were surveyed within Lynnhaven River, Virginia. Fish species diversity, community abundance, biomass, and size structure were compared among creeks and related to watershed, shoreline, and physicochemical characteristics. Mean fish community characteristics (e.g., abundance) were similar among creeks; however, species-specific analysis revealed subtle differences. Species biomass differed between dredged and undredged creeks, though species abundance was similar. Turbidity highly influenced differences in species abundance among creeks, while organic matter, dissolved oxygen, turbidity, and shoreline hardening may be influencing biomass patterns. The most recently dredged creek appeared to provide less suitable nursery habitat for some species than historically dredged creeks, suggesting initial adverse effects with eventual recovery. Protective measures, such as preservation of marshes, dredge depth, and time-of-year restrictions, may be moderating development and dredging pressures.
