Abstract

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 estuarinedependent recruitment and community structure in seagrass habitats adjacent to Packery Channel pre and postchannel 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 October 2004–May 2005 and 1 year after July 2005–April 2006 Using the before–after control–impact design we found significantly fewer nekton postchannel opening However we found significantly higher mean densities of newly settled estuarinedependent species Sciaenops ocellatus Micropogonias undulatus Lagodon rhomboides Callinectes sapidus and penaeid shrimp postopening Multivariate analyses showed significant community assemblage changes postopening with increased contribution of estuarinedependent species postopening Our results show that estuarinedependent 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 speciesWe would like to thank the Coastal Bend Bays and Estuaries Program Texas A and M University Corpus Christi TAMUCC NOAA Sea Grant NA06OAR4170076 and the Coastal Conservation Association for funding this research We thank Dr Paul Montagna Terry Palmer Dr Kim Withers and John Froeschke for their assistance with the analysis We also thank Deidre Williams and Lanmon Aerial Photography Inc for providing aerial photography This project would not have been possible without the members of the Fisheries Ecology Lab at TAMUCC and their numerous hours of field and laboratory help We particularly would like to thank Sarah Bayer Heather Barackman Annette Cardona Rafael Calderon Alyssa Dailey Ryan Fikes Todd Neahr and Brooke Stanford
