“…The level of successful recruitment bringing larvae and postlarvae into estuaries is an important component of habitat use, controlling initial densities of juveniles in different habitat types. Certain characteristics, such as orientation to shoreline, extent and direction of wind induced currents as well as tidal dynamics, appear to promote successful recruitment into particular estuaries (Weinstein et al 1980a, Rothlisberg et al 1983, Weinstein 1988, Rogers et al 1993, Epifanio 1995, Olmi 1995, Morgan et al 1996, Wenner et al 1998. Thus, location with respect to a source of recruits (e.g.…”

We examined the nursery role of salt marshes for transient nekton by searching the literature for data on density, growth, and survival of juvenile fishes and decapod crustaceans in marshes and using meta-analyses to test hypotheses. We analyzed density data from 32 studies conducted throughout the world. Based on fish density, habitat types could be ranked from highest to lowest as: seagrass > vegetated marsh edge, nonvegetated marsh, open water, macroalgae, oyster reefs > vegetated inner marsh. However, patterns of habitat use varied among the 29 fish species represented. For decapod crustaceans (seven species), habitat types were ranked: seagrass > vegetated marsh edge > nonvegetated marsh, vegetated inner marsh, open water, macroalgae > oyster reef. We identified only 5 comparative studies on transient nekton growth in salt marshes. Fish growth in nonvegetated salt marsh was not significantly different from growth in open water or in macroalgae beds but was significantly lower than in seagrass. Growth of decapod crustaceans was higher in vegetated marsh than in nonvegetated marsh. Nekton survival in salt marsh (11 studies analyzed) was higher than in open water, lower than in oyster reef/cobble and not significantly different from survival in seagrass. When density, growth and survival are all considered, the relative nursery value of salt marshes for nekton appears higher than open water but lower than seagrass. Vegetated marsh appears to have a higher nursery value than nonvegetated marsh; however, tidal dynamics and nekton movement among marsh components complicates these comparisons. The available data have a strong geographical bias; most studies originated in the northern Gulf of Mexico or on the Atlantic coast of the United States. This bias may be significant because there is some evidence that salt marsh nursery value is dependent on geography, salinity regimes and tidal amplitude.

“…The field data that motivated this study came from four larval abundance surveys conducted in the North Edisto Inlet in South Carolina ( Wenner et al ., 1998 ). For each of these surveys, the abundance of white shrimp post larvae and blue crab megalopae was determined for night‐time flood tidal currents over a 14‐day period.…”

“…Circulation patterns within inner shelf and coastal sound regions are important to the ingress of the larvae of many marine species from their offshore spawning areas into estuarine larval and juvenile nursery areas ( Boehlert and Mundy, 1988). Within the last decade, scientists have stressed the importance of physical processes which create and maintain a favourable habitat for larvae and postlarvae and influence their transport through inlets to the estuarine nursery grounds ( Weinstein, 1988).…”

Four 14‐day field experiments were conducted to determine the densities of postlarval white shrimp and blue crab megelopae moving into a tidal inlet along the south‐eastern United States. Certain winds directions were statistically associated with peaks in abundance, a result which motivated us to use a high resolution finite‐element numerical model to simulate passive larval transport under a variety of wind directions into the inlet. The passive particles were initially distributed uniformly in a zone of the continental shelf which extended 20 km offshore and 20 km alongshore in either direction. Each simulation was conducted for five tidal cycles (2.5 days) under constant wind stress. These simulations indicated that larvae are withdrawn from the continental shelf into the inlet from a narrow zone parallel to the shoreline but extending less that 5 km offshore. The withdrawal zone changed to one directly offshore of the inlet mouth only for a wind direction that pointed directly toward the inlet mouth. Under downwelling‐favourable winds, particles originating in the surface accumulate along the downwind boundary and drift shoreward with time thus causing a ‘pooling’ of larvae along the coast. This scenario is repeated with less efficiency for upwelling‐favourable winds with particles originating near bottom. The ‘pooling’ process occurs over the scale of the particle domain. A second and smaller scale is indicated by the relatively few particles which are withdrawn into the inlet as they pass inside the 7‐m isobath (within 5 km of the coast). Those that do pass become available for inlets farther downstream.

“…Such connectivity is a feature of coastal ecosystems (Carr et al 2003) where the tide and currents mediate the transport of many larval fish and macroinvertebrate species (e.g. Wenner et al 1998;Bos 1999;Forward and Tankersley 2001) and where estuaries may function as nursery habitats for fish metapopulations (Gillanders et al 2003;Ray 2005;Secor and Rooker 2005).…”

Berm breaching of intermittently closed estuaries, either naturally or due to management practices, results in a physicochemical disturbance due to the flushing of water, material and biota into the ocean and the subsequent tidal influx. In 2007 and 2008 comparative and controlled studies were employed in three New Zealand estuaries: Sawmill Creek (46°04′S 170°12′E), Otokia Creek (45°57′S 179°20′E) and Kaikorai Lagoon (45°56′S 170°23′E), to investigate the impact of berm breaching on the hyperbenthic macroinvertebrate community in intermittently closed estuaries. Significant changes in community structure occurred in both the weekly comparative and the controlled studies (ANOSIM P<0.01). Furthermore, the catch per unit effort of both total and key invertebrate taxa significantly increased after breaching (ANOVA P<0.01). However, substantial numbers of individuals were expelled into the ocean (5,800 individuals, 20-min sample) while new taxa immigrated into the estuaries. Along with migration-related changes to community structure, berm breaches also resulted in the loss of ∼80% of inundated habitat and the concentration of existing populations. Consequently, the management of intermittent estuary connections to the ocean has implications for the ecology of individual, managed estuaries and also for regional coastal populations of epibenthic invertebrates.
