A Comparison Of Fish Assemblages Among Five Habitat Types Within A Caribbean Lagoonal System, Ivan Mateo, William J. Tobias
A Comparison Of Fish Assemblages Among Five Habitat Types Within A Caribbean Lagoonal System, Ivan Mateo, William J. Tobias
Gulf and Caribbean Research
Fish assemblages associated with patch reefs, rubble, seagrass, algal plain, and sandy habitats types were studied at St. Croix's Southeastern barrier reef lagoon using underwater visual census techniques. Higher species richness and fish density were observed over patch reefs/rubble habitat followed by seagrass, algal plain, and unvegetated sandy habitat types. Thalassoma bifasciatum, Haemulon flavolineatum, and Acanthuras chirurgus were the most common fishes in highly structured habitat types (patch reef, rubble). Halichoeres bivittatus, Sparisoma radians, newly settled grunts (l.e., Haemulon spp.), and juveniles of Ocyurus chrysurus were mainly associated with vegetated habitat types (seagrass, algal beds), while …

Abundance And Ecological Distribution Of The "Sete-Barbas" Shrimp Xiphopenaeus Kroyeri (Heller, 1862) (Decapoda: Penaeoidea) In Three Bays Of The Ubatuba Region, Southeastern Brazil, Rogerio C. Costa, Adilson Fransozo, Fulvio A.M. Freire, Antonio L. Castilho
Gulf and Caribbean Research
The influence of environmental factors on the abundance and spatial-temporal distribution of the shrimp Xiphopenaeus kroyeri was investigated in southeastern Brazil over 2 years. Monthly collections were conducted in Mar Virado, Ubatuba and Ubatumirim Bays using a commercial shrimp fishing boat equipped with 2 "double-rig" nets. Each bay was divided into 6 sampling stations, all of which were less than 25 m deep. The spatial distribution of X. kroyeri differed among Bays. Highest abundance values were recorded in areas where silt and clay comprised more than 70% of the bottom sediment. Abundance of X. kroyeri followed a seasonal trend, being …
Consequences Of Ocean Scale Hypoxia Constrained Habitat For Tropical Pelagic Fishes, Eric D. Prince, C. Phillip Goodyear
Consequences Of Ocean Scale Hypoxia Constrained Habitat For Tropical Pelagic Fishes, Eric D. Prince, C. Phillip Goodyear
Gulf and Caribbean Research
Large areas of cold hypoxic water occur as distinct strata in the eastern tropical Pacific and Atlantic oceans as a result of high productivity initiated by intense nutrient upwelling. Recent studies show that this stratum restricts the depth distribution of tropical pelagic marlins, sailfish, and tunas in the eastern tropical Pacific by compressing the acceptable physical habitat into a narrow surface layer. This layer extends downward to a variable boundary defined by a shallow thermocline, often at 25 m, above a barrier of cold hypoxic water. The depth distributions of marlin and sailfish monitored with electronic tags and mean dissolved …
Relative Abundance Of Pelagic Sharks In The Western North Atlantic Ocean, Including The Gulf Of Mexico And Caribbean Sea, Enric Cortes, Craig A. Brown, Lawrence R. Beerkircher
Relative Abundance Of Pelagic Sharks In The Western North Atlantic Ocean, Including The Gulf Of Mexico And Caribbean Sea, Enric Cortes, Craig A. Brown, Lawrence R. Beerkircher
Gulf and Caribbean Research
Little information exists on the status of pelagic shark populations in the Atlantic Ocean, especially in the Gulf of Mexico and Caribbean Sea. We derived indices of relative abundance for pelagic sharks based on mandatory logbooks and observer reports from a scientific observer program of the United States (US) pelagic longline fleet. Time series data from the pelagic longline logbook program (1986-2005) and the pelagic longline observer program (1992-2005) were standardized with Generalized Linear Model (GLM) procedures. Declines in relative abundance for the 6 pelagic shark species or genera examined in the logbook data analysis ranged from 43% for mako …
Large Pelagic Fishes In The Wider Caribbean And Northwest Atlantic Ocean: Movement Patterns Determined From Conventional And Electronic Tagging, Brian E. Luckhurst
Large Pelagic Fishes In The Wider Caribbean And Northwest Atlantic Ocean: Movement Patterns Determined From Conventional And Electronic Tagging, Brian E. Luckhurst
Gulf and Caribbean Research
Conventional tagging data has documented long distance movements (including trans-Atlantic movements) in blue marlin (Makaira nigricans) and yellowfin tuna (Thunnus albacares) within the Atlantic. Swordfish (Xiphius gladius) have also been shown to move substantial distances, although primarily in a north-south direction. There is, however, a paucity of data for wahoo (Acanthocybium solandri). In the past several years, electronic archival (i.e., data recording) tags have significantly advanced our understanding of the behavior and movement patterns of large pelagic fishes. Data from electronic arcltival tags have generally corroborated conventional tagging data with respect to …
A History Of Change And Reorganization: The Pelagic Longline Fishery In Gouyave, Grenada, Sandra Grant, Fikret Berkes, Johnson St. Louis
A History Of Change And Reorganization: The Pelagic Longline Fishery In Gouyave, Grenada, Sandra Grant, Fikret Berkes, Johnson St. Louis
Gulf and Caribbean Research
This paper traces the history of the pelagic surface longline fishery in Gouyave, Grenada, noting 4 major periods of change from pre-1985 to 2004. Reconstructed from document reviews, newspaper articles, oral history, and key informant interviews 1) the pre-1985 period was the time when the longline was introduced and popularized by the Cubans, 2) the period of institutionalization and technology development (1986-1990) corresponded to the strengthening of institutional arrangements and the initial improvements in technology, 3) the Coastal Fisheries Development Project (CFDP) of 1991-1999 was the period of international donor support and further technology change in longline construction, and finally …
Management In The Gulf And Caribbean: Mosaic Or Melting Pot?, Patrick Mcconney, Hazel A. Oxenford, Milton Haughton
Management In The Gulf And Caribbean: Mosaic Or Melting Pot?, Patrick Mcconney, Hazel A. Oxenford, Milton Haughton
Gulf and Caribbean Research
Does ''managing large pelagic fishes" mean the same thing across the diversity of maritime jurisdictions, governance arrangements, economies, languages, cultures, scales of operation and other features of the Gulf and Caribbean region? It would be surprising if it did. Yet international fisheries management urges this mosaic of management to become a melting pot; at least integrated, even if differentiated. This paper examines some themes underlying whether a mosaic or melting pot is the most apt metaphor for where we are, and are headed, in attempts to manage large pelagic fishes in the region. We pay particular attention to the multi-dimensional …

Monthly and annual phytoplankton productivity rates of four Virginia tidal rivers were determined based on a 12-year monitoring study that included sampling stations from tidal freshwater, oligohaline, and mesohaline regions in these rivers. The mean monthly rates and range at these locations were 5.52 (Dec.) to 175.12 (Aug.) mg C m-3 h-1 for tidal freshwater, 12.21 (Jan.) to 149.90 (May) mg C m-3 h-1 in oligohaline regions, and 16.20 (Jan.) to 151.33 (May) mg C m-3 h-1 for the mesohaline. The estimated mean annual 12 year productivity for the different Virginia river sites in …
Factors That Affect Distribution Of Two Species Of Killifish In Northeast Florida Marshes, Stacy N. Galleher
Factors That Affect Distribution Of Two Species Of Killifish In Northeast Florida Marshes, Stacy N. Galleher
UNF Graduate Theses and Dissertations
Fundulus heteroclitus and the closely related F. grondis are mainly distributed along the Atlantic coast of the U.S from Maine to Northeast Florida and from the East coast of Florida throughout the Gulf of Mexico, respectively. Both are resident salt marsh fishes whose range is thought to overlap in Northeast Florida, making them an ideal study system to examine resource partitioning between two closely related species. The objective of this study was to examine the effects of temperature and elevation on potential habitat partitioning of these two species. It is hypothesized that the northern species, F. heteroclitus, would have a …
Amurocrangonyx, A New Genus Of Subterranean Amphipod (Crangonyctidae) From The Russian Far East, With A Redescription Of The Poorly Known Crangonyx Arsenjevi And Comments On Biogeographic Relationships, Dmitry A. Sidorav, John R. Holsinger
Amurocrangonyx, A New Genus Of Subterranean Amphipod (Crangonyctidae) From The Russian Far East, With A Redescription Of The Poorly Known Crangonyx Arsenjevi And Comments On Biogeographic Relationships, Dmitry A. Sidorav, John R. Holsinger
Biological Sciences Faculty Publications
Amurocrangonyx n. gen. is described on the basis of recently collected specimens of Crangonyx arsenjevi (Derzhavin, 1927), a very poorly known subterranean amphipod crustacean originally described from springs in the Khor River basin of the Ussury River drainage in the Russian Far East. The species is redescribed from specimens obtained from the type-locality, Orekhovy spring, and a neotype is designated. A careful examination of the newly acquired material, although closely similar morphologically to Crangonyx, suggests that it represents a new genus in Crangonyctidae. However, determination of the precise phylogeographic relationship of Amurocrangonyx to Crangonyx or to other crangonyctoid genera …

Cframp's Large Pelagic Fish Tagging Program, Susan Singh-Renton, John Renton
Gulf and Caribbean Research
CFRAMP's Large Pelagic Fish Tagging Program was established to examine the distribution and movement patterns of Thunnus atlanticus (blackfin tuna), Acanthocybium solandri (wahoo), Coryphaena hippurus (dolphinfish), and Scomberomorus cavalla (king mackerel), large pelagic fish species of commercial importance to several Caribbean countries. The Program explored several means to facilitate fish tag and release activities, involving collaborative partnerships with national fisheries administrations, the recreational fishing sector, and individual commercial fishers. A Iotal of 1,143 fish were tagged and released in the coastal waters of several islands within the Eastern Caribbean: 787 blackfin tuna, 250 wahoo, 89 dolphinfish, and 17 king mackerel. …

Breeding Season And Molt Cycle Of The Fiddler Crab Uca Rapax (Brachyura, Ocypodidae) In A Subtropical Estuary, Brazil, South America, Daniela Da Silva Castiglioni, Maria Lucia Negreiros-Fransozo, Rosana Carina Flores Cardoso
Gulf and Caribbean Research
This is the first account of the breeding season and molt cycle of Uca rapax on the Brazilian coast during a one-year period (April 2001-March 2002). At 2 sites, the ltamambuca and Ubatumirim mangrove forests, 2 collectors captured crabs once a month at low tide far 15 minutes by the catch-per-unit-effort procedure, digging into the sediment and removing the crabs. The gonad-development stages of crabs of both sexes were determined by direct observation, and the molt stage was estimated from the hardness of the tegument. Crabs with developed gonads were found mostly in warmer seasons, with ovigerous females occurring mainly …

Distribution Of Molidae In The Northern Gulf Of Mexico, Gregory L. Fulling, Dagmar Fertl, Kevin Knight, Wayne Hoggard
Distribution Of Molidae In The Northern Gulf Of Mexico, Gregory L. Fulling, Dagmar Fertl, Kevin Knight, Wayne Hoggard
Gulf and Caribbean Research
We compiled all available sighting, stranding and bycatch data for the Family Molidae (molas) in the northern Gulf of Mexico (NGOM) to assess spatial and temporal distribution. Overall, 483 records were collected from shipboard and aerial surveys, fisheries bycatch, and strandings. Molas were recorded year-round, with a ubiquitous distribution in both nearshore and offshore waters. Ocean sunfish (Mola mola) were sighted with greatest frequency during the winter (December thru April) in sea surface temperature < 24° C. Potential reasons for increased sightings during winter may be related to the lack of a well-defined thermocline in the NGOM; the species' "basking" behavior associated with thermoregulation; and oxygen replenishment after long, deep dives to oxygen-deficient depths.

Among crustacean decapods, fiddler crabs of the genus Uca are the most characteristic of the intertidal zones of tropical and subtropical estuaries. The present study determined the growth phases and the beginning of differential growth between the sexes, based on analyses of relative growth of Uca maracoani. Collections were made in the Jabaquara mangrove, located in Paraty, Rio de Janeiro, Brazil. Specimens were collected manually during low tide periods. In the laboratory, crabs were sexed and measured. We measured carapace width (CW), carapace length (CL), propodus length (PL; the right one for females and the major one for males), …

New Records Of Alien Mollusca In The Hawaiian Islands: Non-Marine Snails And Slugs (Gastropoda) Associated With The Horticultural Trade, Kenneth Hayes, C. Tran, Robert Cowie
Department of Biology Faculty Publications
The nonmarine snails of the Hawaiian Islands have been cataloged by Cowie (1997),reviewed by Cowie (1998a), and subsequent new records reported by Cowie (1998b, 1999,2000). The horticultural industry has been implicated in the transport and introduction ofsnails and slugs in various parts of the world (e.g., Robinson 1999; Barrientos 2000; Cowie&Robinson 2003; Robinson & Slapcinsky 2005), including Hawai‘i (e.g., Cowie 1998b,1999, 2000). Therefore, between 2004 and 2006 we undertook field surveys of nurseries,botanical gardens, and other similar facilities involved in the cultivation of plants, includ-ing aquatic plants, for sale, recreation or research on the six largest of the main HawaiianIslands, …

This is a retrospective study of shifts in species composition of epiphytic macroalgae that occurred during a period of seagrass loss in Cockburn Sound, Western Australia. Detailed analysis of data on relative abundances of 108 epiphytic taxa collected over 2 yr from 27 widely dispersed sites around Cockburn Sound showed differences in epiphyte composition between sites with loss of seagrasses (Loss sites) and those with no loss in the the long-term (No Loss sites). Future seagrass losses, however, were not predicted by shifts in species composition. Most species were rare and varied with season of sampling. Hence, varying assemblages of …

Effect Of Leaf Movement On Epiphytic Algal Biomass Of Seagrass Leaves, Paul Lavery, Tara Reid, Glenn Hyndes, Beverley Van Elven
Research outputs pre 2011
We tested the hypothesis that the movement of seagrass leaves affects the accumulation and composition of algal epiphytes by comparing the standing crop and composition on tethered (T) and untethered (UT) artificial seagrass units (ASUs) over 4 and 8 wk. We also tested whether any effect of leaf movement on standing crop was dependent on the degree of water movement by repeating the experiment over 8 wk at sheltered and exposed sites. To eliminate the possibility of inter-regional differences between exposed and sheltered sites and to test for interactive effects of light availability and leaf movement on epiphyte biomass, we …

Morphological, Growth And Meadow Characteristics Of The Seagrass Posidonia Sinuosa Along A Depth-Related Gradient Of Light Availability, Cj Collier, Paul Lavery, Rj Masini, Pj Ralph
Research outputs pre 2011
Morphological and growth characteristics of the meadow-forming seagrass Posidonia sinuosa (Cambridge et Kuo), were measured along a depth-related gradient of light to infer its response to long-term differences in light availability. Morphometric measurements were carried out at 6 depths between 1.6 and 9.0 m in summer and winter at Cockburn Sound and summer only at Warnbro Sound in south-western Australia. The minimum light requirement for P. sinuosa of 8.5% sub-surface light was among the lower range reported for seagrasses. Its slow growth rate (0.5–1.5 mgdry shoot–1 d–1), relative to similarly sized species, may contribute to the low light requirements of …

The Use Of Detached Kelp (Ecklonia Radiata) By Seagrass-Associated Mesograzers In Temperate South-Western Australia, Christopher Doropoulos
The Use Of Detached Kelp (Ecklonia Radiata) By Seagrass-Associated Mesograzers In Temperate South-Western Australia, Christopher Doropoulos
Theses : Honours
The movement of nutrients and organisms between habitats provide important spatial subsidies on local and regional scales, resulting in increased primary and secondary production, especially where inputs supplement habitats of relatively low levels of comparable resources. In coastal south-western Australia, the brown kelp, Ecklonia radiata, is produced in large quantities on offshore reefs from where it detaches and passes through neighbouring habitats. This allochthonous resource is present in large quantities in seagrass meadows and thereby potentially influences the trophic dynamics of this habitat, providing an additional food source for grazers to those produced in situ. This study investigated the effects …

Marine natural products play critical roles in the chemical defense of many marine organisms and in some cases can influence the community structure of entire ecosystems. Although many marine natural products have been studied for biomedical activity, yielding important information about their biochemical effects and mechanisms of action, much less is known about ecological functions. The way in which marine consumers perceive chemical defenses can influence their health and survival and determine whether some natural products persist through a food chain. This article focuses on selected marine natural products, including okadaic acid, brevetoxins, lyngbyatoxin A, caulerpenyne, bryostatins, and isocyano terpenes, …

School of Earth, Environmental, & Marine Sciences Faculty Publications
Shell damage, if properly recognized, can provide information about biotic interactions between molluscs and their predators. However, it can be difficult to distinguish predatory damage from mechanical breakage, thus making interpretation of damaged modern and fossil shells problematic. To establish a clear-cut distinction between antemortem predatory crab damage and ante- and postmortem mechanical damage in Mytilus trossulus shells, a combined field and experimental approach was used. Mussels were exposed to predation by crabs, tumbled-live, tumbled-dead, and trampled. After 100 h of tumbling, live-collected mussel shells were abraded and disarticulated but not otherwise damaged. Eight percent of the dead-collected shells were …

Estuaries play a key role in the juvenile stage of gag (Myeteroperca microlepis). The use of estuarine habitats by juvenlle gag has been examined in temperate estuaries, which are at the northern limits of the range of this species, but the importance of subtropical estuaries during the early life history of this species has not been studied extensively. Gag were collected in subtropical Charlotte Harbor, Florida, during routine monthiy sampling from January 1996 to Decemher 2002. Juvenlle gag were collected using a 21.3-m seine, a 183-m haul seine, and a 183-m purse seine. A total of 738 individuals …

The Southeast Fisheries Science Center (SEFSC) of the US NOAA Fisheries provides much of the US science advice for the management of Highly Migratory Species (HMS) in the Atlantic, Gulf of Mexico and US Caribbean Sea. These stocks include the tunas, sharks, billfishes and swordfish all of which are targeted either commercially or recreationally or both in US waters. These species are managed internationally through membership to the International Commission for the Conservation of Atlantic Tunas (ICCAT); however, while the US is an ICCAT member, few Caribbean nations are members.
