Evidence Of Spawning Capable Tarpon (Megalops Atlanticus) Off The Louisiana Coast, William Stein Iii, Nancy J. Brown-Peterson, James S. Franks, Martin T. O'Connell
Gulf and Caribbean Research
Despite the fact that the tarpon (Megalops atlanticus) is a popular sport fish in the Gulf of Mexico (GOM; Ault et al. 2008), little is known of its spawning behavior. Spawning M. atlanticus have never been documented and fertilized eggs have not been observed in situ (Ault et al. 2008). While it has been suggested that adult M. atlanticus move to deep water off the southwest coast of Florida and into the Yucatan Channel to spawn, the actual locations of spawning grounds remain unknown (Smith 1980, Crabtree et al. 1995, Crabtree et al. 1997). Distribution patterns of larvae …
A New Baseline For Diadema Antillarum, Echinometra Viridis, E. Lucunter, And Eucidaris Tribuloides Populations Within The Cayos Cochinos Mpa, Honduras, Paul A.X. Bologna, Lucy Webb-Wilson, Patrick Connelly, James E. Saunders
A New Baseline For Diadema Antillarum, Echinometra Viridis, E. Lucunter, And Eucidaris Tribuloides Populations Within The Cayos Cochinos Mpa, Honduras, Paul A.X. Bologna, Lucy Webb-Wilson, Patrick Connelly, James E. Saunders
Gulf and Caribbean Research
We investigated the density of 4 urchin species from 5 shallow reefs in the Cayos Cochinos Marine Protected Area in Honduras. Individual species density varied among reefs with total urchin density ranging from 3.2–7.9 individuals/m2. Echinometra viridis (Agassiz, 1863) was the numerically dominant species (2.29/m2) followed by E. lucunter (Linnaeus, 1758) (1.76/m2) with Eucidaris tribuloides (Lamarck 1816) representing the fewest individuals (0.42/m2). Our results indicated that density of Diadema antillarum (Philippi, 1845) differed significantly among reefs (0.4-1.3/m2, mean = 0.63/m2), but are three times greater than data collected …
Determination Of The Spawning Season Of Bigmouth Sleeper In Puerto Rico By Examination Of Gonad Maturation And Reproductive Hormone Cycles, Nathan J. Harris, J. Wesley Neal, Todd D. Sink, Peter W. Perschbacher
Determination Of The Spawning Season Of Bigmouth Sleeper In Puerto Rico By Examination Of Gonad Maturation And Reproductive Hormone Cycles, Nathan J. Harris, J. Wesley Neal, Todd D. Sink, Peter W. Perschbacher
Gulf and Caribbean Research
Bigmouth sleepers, Gobiomorus dormitor, are diadromous fish that have potential for hatchery production as both food and sport fish and for conservation purposes. Understanding of bigmouth sleeper maturation and seasonal hormone cycling are necessary in order to realize hatchery production. Therefore, seasonal trends in gonadosomatic index (GSI) and plasma vitellogenin, estradiol, progesterone and total testosterone concentrations were examined in wild and captive populations in Puerto Rico during the presumed spawning season. The spawning season for wild river populations of bigmouth sleepers was protracted over several months, but peaks in male testosterone (6.5 ng/mL) and female vitellogenin (11.3 ng/mL), estradiol …
Effects Of A Severe Cold Event On The Subtropical, Estuarine-Dependent Common Snook, Centropomus Undecimalis, Aaron J. Adams, Jessica E. Hill, Benjamin N. Kurth, Andrew B. Barbour
Effects Of A Severe Cold Event On The Subtropical, Estuarine-Dependent Common Snook, Centropomus Undecimalis, Aaron J. Adams, Jessica E. Hill, Benjamin N. Kurth, Andrew B. Barbour
Gulf and Caribbean Research
The effects of infrequent disturbance events on marine fishes are often difficult to determine, due largely to lack of sufficient pre- and post-disturbance event data. In January 2010, subtropical southwestern Florida (USA) experienced extreme cold for 13 days, which caused extensive mortality of many fish species. The effect of this severe cold event on common snook (Centropomus undecimalis), an economically important gamefish, was assessed using three years (2007-2009) of pre-event and one year (2010) of post-event data from a tag-recapture program conducted over 28 km of Gulf of Mexico barrier islands of Florida. All metrics pointed to a …
A Western Range Extension For Caprella Scaura (Amphipoda: Caprellidae) In The Aransas Bay Ecosystem, Texas, Nicholas L. Ahrens, Faye P. Grubbs
A Western Range Extension For Caprella Scaura (Amphipoda: Caprellidae) In The Aransas Bay Ecosystem, Texas, Nicholas L. Ahrens, Faye P. Grubbs
Gulf and Caribbean Research
During March 2009, the skeleton shrimp Caprella scaura and Paracaprella tenuis (Amphipoda: Caprellidae) were collected from several locations throughout the Aransas Bay, Texas ecosystem from Texas Parks and Wildlife fishery—independent trawl and oyster dredge samples. This is a western range expansion for C. scaura; P. tenuis has been reported from this area before. Both species were exclusively associated with a bryozoan, Bugula neritina. Densities of both species ranged between 0.1–3.4 individuals per gram of attached bryozoans. A reproductive population is likely established since several sizes, including adult males and gravid females, were observed. No caprellids were observed after …
Early Growth Of Three Kingfish (Menticirrhus) Species Found In Coastal Waters Of The Northern Gulf Of Mexico, E. John Anderson, Bruce H. Comyns, Harriet Perry, Chet F. Rakocinski
Early Growth Of Three Kingfish (Menticirrhus) Species Found In Coastal Waters Of The Northern Gulf Of Mexico, E. John Anderson, Bruce H. Comyns, Harriet Perry, Chet F. Rakocinski
Gulf and Caribbean Research
Southern kingfish (Menticirrhus americanus), gulf kingfish (M. littoralis), and northern kingfish (M. saxatilis) are members of the drum family (Sciaenidae) that are widespread in coastal habitats of the western Atlantic, including in the Gulf of Mexico (GOM). Despite their economic and ecological importance, little is known about growth of young kingfish. Young kingfish were collected from four different Mississippi shoreline habitats in 2005 and 2006; two associated with barrier islands and two along the mainland. Barrier island habitats included surf zones on the south shore and grass beds on the north shore. Mainland habitats …
An Evaluation Of Mississippi Barrier Islands As A Spawning And Nesting Habitat For The American Horseshoe Crab, Limulus Polyphemus, With Implications For Island Restoration, Richard Fulford, Rebecca A. Haehn
An Evaluation Of Mississippi Barrier Islands As A Spawning And Nesting Habitat For The American Horseshoe Crab, Limulus Polyphemus, With Implications For Island Restoration, Richard Fulford, Rebecca A. Haehn
Gulf and Caribbean Research
The American horseshoe crab (HSC), Limulus polyphemus, is an economically and ecologically important species in the coastal ecosystem. Horseshoe crabs inhabit the continental shelf and estuaries from Maine to the central Gulf Coast and the Yucatán Peninsula. Although the presence of horseshoe crabs in southern Mississippi is known locally, there are limited data specific to the area and population, particularly regarding spawning and nesting habitat. Surveys of HSC presence, habitat use, and behavior on Mississippi barrier islands were conducted between March and November 2007 to 2009. These data, combined with habitat surveys of the barrier islands, were used to …
Flexible Feeding Strategies Of Juvenile Gray Triggerfish (Balistes Capriscus) And Planehead Filefish (Stephanolepis Hispidus) Within Sargassum Habitat, Sarah E. Ballard, Chet F. Rakocinski
Flexible Feeding Strategies Of Juvenile Gray Triggerfish (Balistes Capriscus) And Planehead Filefish (Stephanolepis Hispidus) Within Sargassum Habitat, Sarah E. Ballard, Chet F. Rakocinski
Gulf and Caribbean Research
Sargassum-associated juvenile gray triggerfish and planehead filefish exhibited flexible feeding strategies in terms of their use of epifauna or pelagic zooplankton. Four diet samples represented instances of co-occurrence and segregated occurrence. Co-occurring gray triggerfish had the most specialized diets consisting mainly of pelagic copepods and hyperiid amphipods. Conversely, segregated triggerfish as well as both co-occurring and segregated filefish had broader diets mainly consisting of Sargassum epifauna, such as bryozoans, portunid crabs, and hippolytid shrimp. Still, co-occurring planehead filefish also consumed somewhat more zooplankton than segregated planehead filefish. Ontogenetic diet transitions were not as distinct for gray triggerfish as for …

Using The Fishes Of Texas Project Databases And Recent Collections To Detect Range Expansions By Four Fish Species On The Lower Coastal Plain Of Texas, F. Douglas Martin, Adam E. Cohen, Dean A. Hendrickson
Gulf and Caribbean Research
The Fishes of Texas project online database is a large, freely available quality controlled fish occurrence database of museum vouchered specimens. We used data from it, the same project’s separate database of occurrences extracted from published literature and our own recent survey data to examine range stability for four fish species inhabiting the Texas Lower Coastal Plain: Fundulus chrysotus, Fundulus jenkinsi, Heterandria formosa and Poecilia formosa. A weakness of our data is that they consist of presences only and species absences can only rarely be inferred. To help adjust for this we used common widespread species as …
