“…The goal of this analysis was to test for differences in community assemblages post-channel opening by using several routines from PRIMER (Ludwig and Reynolds 1988;Catalán et al 2006). We examined the mean densities of each species collected by date (14 total) for pre-and post-opening.…”

The US Army Corps of Engineers recently dredged and permanently reopened Packery Channel, historically a natural tidal inlet, to allow water exchange between the Gulf of Mexico and the Laguna Madre, TX, USA. The main objective of this study was to characterize estuarine-dependent recruitment and community structure in seagrass habitats adjacent to Packery Channel pre-and post-channel opening. We sampled fish and crustacean abundance using an epibenthic sled in Halodule wrightii seagrass meadows in both control and impact locations over 2 years, 1 year before the opening of Packery Channel ). Using the before-after control-impact design, we found significantly fewer nekton post-channel opening. However, we found significantly higher mean densities of newly settled estuarine-dependent species (Sciaenops ocellatus, Micropogonias undulatus, Lagodon rhomboides, Callinectes sapidus, and penaeid shrimp) post-opening. Multivariate analyses showed significant community assemblage changes post-opening with increased contribution of estuarine-dependent species post-opening. Our results show that estuarine-dependent nekton are using Packery Channel as a means of ingress into areas of the upper Laguna Madre's seagrass meadows that were previously inaccessible, which may lead to higher fisheries productivity for some of these economically and ecologically important fishery species.

“…A. regius can attain up to c. 200 cm total length (L T ; Quero and Vayne, 1987). Spawning is believed to occur within or nearby estuaries and salt marshes, where large-size specimens are observed during a certain period of the year (Champagnat and Domain, 1978;Quero and Vayne, 1987) and small-size juveniles (c. <20 cm) are found (Quero and Vayne, 1987;Cabral and Ohmert, 2001;Baldó and Drake, 2002;Catalán et al, 2006).…”

“…Variation in the responses of different fish species to the same suite of environmental variables has been noted in other studies. Catalan et al (2006) found that the spatial and temporal changes of coastal demersal assemblages in the Gulf of Cadiz (SW Spain) in relation to environmental conditions was species-specific. The absence of correlation in species richness may also have occurred because the potential variation in species richness of syngnathids is small, relative to other fish, because of the limited number of species of syngnathids.…”

ABSTRACT1. Syngnathids (Pisces, Syngnathidae: seahorses and pipefish) were investigated for their use as a flagship group to evaluate the conservation value of estuarine seagrass beds in estuaries in south-east Australia. Some species of syngnathids are listed internationally as vulnerable or endangered, and they are a charismatic group of fish that attracts a high level of public support and sympathy. Syngnathids are also protected in several states of Australia. Conservation of syngnathids might provide coincidental benefits to other species that share their habitats.2. The effectiveness of syngnathids as a flagship group was assessed by (1) testing for correlations with other fish in species richness, density, assemblage variation, and summed irreplaceability value, and (2) determining the number of species of all other fish coincidentally captured in marine protected areas (MPAs) selected for syngnathids. The study was undertaken in a single estuary (scale: tens of square kilometres) and across multiple estuaries (scale: hundreds of square kilometres).3. Densities of syngnathids and other fish were correlated only at the scale of multiple estuaries. Species richness and summed irreplaceability of syngnathids and other fish were not spatially correlated. Spatial variations in assemblages of syngnathids and other fish were correlated. MPAs selected for syngnathids included more non-syngnathid species than a random selection of locations.4. This study provides evidence that ranking the conservation value of seagrass beds on the basis of the density and assemblage variation of syngnathids, and selecting MPAs to represent syngnathid species, will simultaneously benefit other fish. Synganthids are therefore regarded as a useful flagship group for conservation planning.
