Endohelminths Of A Snake Mackerel, Gempylus Serpens (Trichiuroidea: Gempylidae), From The Gulf Of Mexico, Charles K. Blend, Norman O. Dronen, James S. Franks, George W. Benz
Endohelminths Of A Snake Mackerel, Gempylus Serpens (Trichiuroidea: Gempylidae), From The Gulf Of Mexico, Charles K. Blend, Norman O. Dronen, James S. Franks, George W. Benz
Gulf and Caribbean Research
Endohelminths are reported from a female snake mackerel, Gempylus serpens (Trichiuroidea: Gempylidae), captured from a depth of 61 m in the Gulf of Mexico 140 km south of the mouth of Mobile Bay, AL, in August 1998. A diverse endohelminth parasite fauna was found: 29 plerocercoid type I tetraphyllideans from the lower intestine; 4 didymozoid metacercariae allocated to the collective group Monilicaecum and one didymozoid metacercaria of the collective group Torticaecum from the pyloric cecum; one juvenile Gonocerca phycidis from the stomach; and 5 larvae (L3 stage) comprising 3 species of Anisakis from the pyloric cecum. These nematodes were identified …
Observations Of A Black Grouper (Mycteroperca Bonaci) Spawning Aggregation In Bermuda, Brian E. Luckhurst
Observations Of A Black Grouper (Mycteroperca Bonaci) Spawning Aggregation In Bermuda, Brian E. Luckhurst
Gulf and Caribbean Research
Diving observations at a black grouper (Mycteroperca bonaci) spawning aggregation site on Bermuda’s reef platform revealed many similarities to observations of this species obtained at multi-species spawning aggregation sites in Belize. In addition to similarities in body sizes, color patterns and some behavior, the principal spawning period in the days after the full moon was also similar. Although spawning was not observed in this study, there was ample indirect evidence of spawning at the site, i.e. courtship behavior by males, females with distended abdomens, and color changes. The formation of temporary spawning territories by males and courtship behavior …
Growth Patterns Of Shoal Grass Halodule Wrightii And Manatee Grass Syringodium Filiforme In The Western Gulf Of Mexico, Melissa A. Gutierrez, Annette A. Cardona, Delbert L. Smee
Growth Patterns Of Shoal Grass Halodule Wrightii And Manatee Grass Syringodium Filiforme In The Western Gulf Of Mexico, Melissa A. Gutierrez, Annette A. Cardona, Delbert L. Smee
Gulf and Caribbean Research
Although manatee grass is becoming increasingly abundant in Texas bays, its growth characteristics have not been measured in the western GOM. Changes in seagrass species composition can have significant community effects (Micheli et al. 2008), but the effects of a transition from shoal to manatee grass in the LM have not been extensively studied (but see Tolan et al. 1997). The goals of our study were to measure growth patterns of these two seagrass species in two locations in the western GOM that vary in salinity, epiphyte loads, and nutrient inputs.

Within the western North Atlantic Ocean there are at least 4 genera and 5 species of chimaeroids occurring in deep waters generally associated with outer continental slopes or areas of high bathymetric relief (Didier 2002; Didier 2004). Two chimaeroids, Chimaera cubana and Hydrolagus alberti, are known to be indigenous to the Caribbean Sea in waters associated with the Greater and Lesser Antilles. While H. alberti occurs throughout the Gulf of Mexico and the Caribbean Sea, C. cubana is thought to be endemic to an area bounded by Cuba and Colombia (IUCN 2009). These two chimaeras are readily differentiated by …
Do Small, Patchy, Constructed Intertidal Oyster Reefs Reduce Salt Marsh Erosion As Well As Natural Reefs?, Alix G. Stricklin, Mark S. Peterson, John D. Lopez, Christopher A. May, Christina F. Mohrman, Mark S. Woodrey

One ecological service that oyster reefs provide is stabilization of shorelines through reduced wave energy and erosion from boat traffic, storms, and predominant wind direction. Additionally, increasing sedimentation can enhance the growth of emergent marsh vegetation which further stabilizes unconsolidated sediments. A 21 mo study of constructed (with only 30-35% coverage) and natural oyster reefs in 3 bayous in the Grand Bay National Estuarine Research Reserve (NERR) suggested constructed reefs benefit this retrograding deltaic ecosystem. The marsh edge adjacent to all constructed reefs was less eroded (mean = 0.043 m) than edges adjacent to natural reefs (mean = 0.728 m), …
Observations On The Kalliapseudid Tanaidacea (Crustacea: Malacostraca: Peracarida) From The Northwestern Atlantic, With An Illustrated Key To The Species, David T. Drumm, Richard W. Heard
Observations On The Kalliapseudid Tanaidacea (Crustacea: Malacostraca: Peracarida) From The Northwestern Atlantic, With An Illustrated Key To The Species, David T. Drumm, Richard W. Heard
Gulf and Caribbean Research
New information for the kalliapseudid Tanaidacea occurring in the northwestern Atlantic is presented and discussed, including data on range extensions and new depth ranges for 4 species. The taxa studied came from the shelf and coastal waters of the southeastern United States, Puerto Rico and Trinidad. The occurrence of Mesokalliapseudes bahamensis Sieg is extended from the Bahamas and Belize to the coastal waters of East and Gulf coasts (South Carolina to West Florida). The range of Psammokalliapseudes granulosus Brum is expanded northward into the eastern Gulf of Mexico and new locality records for this species are established for Tobago and …
Effects Of Hurricane Katrina On An Incipient Population Of Giant Salvinia Salvinia Molesta In The Lower Pascagoula River, Mississippi, Pam L. Fuller, Mike G. Pursley, Dale Diaz, Wesley Devers
Effects Of Hurricane Katrina On An Incipient Population Of Giant Salvinia Salvinia Molesta In The Lower Pascagoula River, Mississippi, Pam L. Fuller, Mike G. Pursley, Dale Diaz, Wesley Devers

The objectives of this study were to: 1) survey the lower Pascagoula River Basin and determine the post–storm distribution and abundance of giant salvinia; 2) control any remaining giant salvinia through physical and/or chemical means; 3) determine the fate of the bio–control agents; and 4) determine if re–introduction of salvinia weevils is needed and if so, to decide where best to release them.
Recruitment And Colonization Of Macroalgae To A Newly Constructed Rocky Intertidal Habitat In The Northwest Gulf Of Mexico, Ryan L. Fikes, Roy L. Lehman
Recruitment And Colonization Of Macroalgae To A Newly Constructed Rocky Intertidal Habitat In The Northwest Gulf Of Mexico, Ryan L. Fikes, Roy L. Lehman
Gulf and Caribbean Research
Marine macroalgal assemblages on artificial structures play an important ecological role in coastal and estuarine ecosystems and may supplement natural communities in nearby waters. The rocky jetties of Packery Channel, located near Corpus Christi, Texas represent a recent addition of hard structure for colonization in the northwest Gulf of Mexico. The purpose of this research was to monitor the initial immigration of macroalgal species during the first year of colonization and determine the effects of wave energy on recruitment. Ten sampling sites were established along the offshore portion of the new Packery Channel jetties. Samples were taken bimonthly from along …
Evaluating Management Actions For Spotted Seatrout, Cynoscion Nebulosus, In Mississippi With An Age-Structured Projection Model, Richard S. Fulford, J. Read Hendon
Evaluating Management Actions For Spotted Seatrout, Cynoscion Nebulosus, In Mississippi With An Age-Structured Projection Model, Richard S. Fulford, J. Read Hendon
Gulf and Caribbean Research
Spotted seatrout, Cynoscion nebulosus, is an important recreational fishery in the coastal waters of the Gulf of Mexico and is the most sought after gamefish in coastal Mississippi. The management of C. nebulosus is state-specific, and unlike other similarly managed species, data on both population structure and movement support the existence of local sub-stocks. It is important for each state to clearly examine its own sub-stock in the context of its own state fishery in order to properly manage for local sustainability. We used an age-structured assessment model to examine the status (1993–2005) of the Mississippi C. nebulosus population …
