Dietary Metal And Macro-Nutrient Intakes Of Juvenile Lemon Sharks Determined From The Nutritional Composition Of Prey Items, Harri Pettitt-Wade, Steven P. Newman, Kristene T. Parsons, Et Al
VIMS Articles
The trace element requirements of sharks are poorly understood and the dietary intake of metals from prey items in wild sharks has not been measured. In this study whole prey of nursery bound juvenile lemon sharks Negaprion brevirostris, from Bimini, Bahamas were analysed for carcass total protein, lipids, carbohydrates, ash content, energy, and elemental composition. Metal analysis included 415 prey items from 18 species (fish: Atherinidae, Belonidae, Gerreidae, Haemulidae, Lutjanidae, Scaridae, Sphyraenidae; decapod crustaceans: Penaeidae, Portunidae). There were some seasonal and location effects (North Sound versus South Bimini shark nurseries), but overall prey metal concentrations were broadly similar to …

From 2001 to 2006, 71 pop-up satellite archival tags (PSATs) were deployed on five species of pelagic shark (blue shark [Prionace glauca]; shortfin mako [Isurus oxyrinchus]; silky shark [Carcharhinus falciformis]; oceanic whitetip shark [C. longimanus]; and bigeye thresher [Alopias superciliosus]) in the central Pacific Ocean to determine speciesspecific movement patterns and survival rates after release from longline fishing gear. Only a single postrelease mortality could be unequivocally documented: a male blue shark which succumbed seven days after release. Meta-analysis of published reports and the current study (n=78 reporting PSATs) indicated that the summary effect of postrelease mortality for blue sharks …

The Influence Of An Innovative Locomotor Strategy On The Phenotypic Diversification Of Triggerfish (Family: Balistidae), A Dornburg, B Sidlauskas, F Santini, L Sorenson, Tj Near, Me Alfaro
VIMS Articles
Innovations in locomotor morphology have been invoked as important drivers of vertebrate diversification, although the influence of novel locomotion strategies on marine fish diversification remains largely unexplored. Using triggerfish as a case study, we determine whether the evolution of the distinctive synchronization of enlarged dorsal and anal fins that triggerfish use to swim may have catalyzed the ecological diversification of the group. By adopting a comparative phylogenetic approach to quantify median fin and body shape integration and to assess the tempo of functional and morphological evolution in locomotor traits, we find that: (1) functional and morphological components of the locomotive …

Regional Variation In The Annual Feeding Cycle Of Juvenile Walleye Pollock (Theragra Chalcogramma) In The Western Gulf Of Alaska, Matthew T. Wilson, Andre Buchheister, Christina M. Jump
VIMS Articles
Juvenile fish in temperate coastal oceans exhibit an annual cycle of feeding, and within this cycle, poor wintertime feeding can reduce body growth, condition, and perhaps survival, especially in food-poor areas. We examined the stomach contents of juvenile walleye pollock (Theragra chalcogramma) to explain previously observed seasonal and regional variation in juvenile body condition. Juvenile walleye pollock (1732 fish, 37-250 mm standard length) of the 2000 year class were collected from three regions in the Gulf of Alaska (Kodiak, Semidi, and Shumagin) representing an area of the continental shelf of ca. 100,000 km(2) during four seasons (August 2000 to September …

Comparative Metabolic Rates Of Common Western North Atlantic Ocean Sciaenid Fishes, A. Z. Horodysky, R. W. Brill, P. G. Bushnell, Jack A. Musick, R. J. Latour
VIMS Articles
The resting metabolic rates (R ) of western North Atlantic Ocean sciaenids, such as Atlantic croaker Micropogonias undulatus, spot Leiostomus xanthurus and kingfishes Menticirrhus spp., as well as the active metabolic rates (R ) of M. undulatus and L. xanthurus were investigated to facilitate inter and intraspecific comparisons of their energetic ecology. The R of M. undulatus and L. xanthurus were typical for fishes with similar lifestyles. The R of Menticirrhus spp. were elevated relative to those of M. undulatus and L. xanthurus, but below those of high-energy-demand species such as tunas Thunnus spp. and dolphinfish Coryphaena hippurus. Repeated-measures non-linear …
Sea Turtles As Potential Dispersal Vectors For Non-Indigenous Species: The Veined Rapa Whelk As An Epibiont Of Loggerhead Sea Turtles, Jm Harding, Wj Walton, Cm Trapani, Mj Frick, Roger L. Mann
Sea Turtles As Potential Dispersal Vectors For Non-Indigenous Species: The Veined Rapa Whelk As An Epibiont Of Loggerhead Sea Turtles, Jm Harding, Wj Walton, Cm Trapani, Mj Frick, Roger L. Mann
VIMS Articles
We present the first record of Rapana venosa (Veined Rapa Whelk) as an epibiont of Caretta caretta (Loggerhead Sea Turtle) and the first observation of rapa whelks in the South Atlantic Bight, USA. Veined Rapa Whelks are invasive shellfish predators. The only known North American population of Veined Rapa Whelks is in the southern Chesapeake Bay. Collections of Veined Rapa Whelks as epibionts on Loggerhead Sea Turtles from Norfolk, VA and Wassaw Island, GA present a previously undescribed vector for whelk range expansion to widely separated coastal habitats. In October 2008, a live juvenile Loggerhead stranded near Norfolk, VA with …

Climate-Related Hydrological Regimes And Their Effects On Abundance Of Juvenile Blue Crabs (Callinectes Sapidus) In The Northcentral Gulf Of Mexico, Guillermo Sanchez-Rubio, Harriet M. Perry, Patricia M. Biesiot, Donald R. Johnson, Rom Lipcius
VIMS Articles
The abundance of juvenile blue crabs (Callinectes sapidus) in the northcentral Gulf of Mexico was investigated in response to climate-related hydrological regimes. Two distinct periods of blue crab abundance (1, 1973-94 and 2, 1997-2005) were associated with two opposite climate-related hydrological regimes. Period 1 was characterized by high numbers of crabs, whereas period 2 was characterized by low numbers of crabs. The cold phase of the Atlantic Multidecadal Oscillation (AMO) and high north-south wind momentum were associated with period 1. Hydrological conditions associated with phases of the AMO and North Atlantic Oscillation (NAO) in conjunction with the north-south wind momentum …

An Evaluation Of The Effects Of Blue Crab (Callinectes Sapidus) Behavior On The Efficacy Of Crab Pots As A Tool For Estimating Population Abundance, Samuel Kersey Sturdivant, Kl Clark
VIMS Articles
Crab traps have been used extensively in studies on the population dynamics of blue crabs to provide estimates of catch per unit of effort; however, these estimates have been determined without adequate consideration of escape rates. We examined the ability of the blue crab (Callinectes sapidus) to escape crab pots and the possibility that intraspecific crab interactions have an effect on catch rates. Approximately 85% of crabs that entered a pot escaped, and 83% of crabs escaped from the bait chamber (kitchen). Blue crabs exhibited few aggressive behavioral interactions in and around the crab pot and were documented to move …

The depauperate marine ecosystems of the Hawaiian Archipelago share a high proportion of species with the southern and western Pacific, indicating historical and/or ongoing connections across the large oceanic expanse separating Hawaii from its nearest neighbors. The rate and direction of these interactions are, however, unknown. While previous biogeographic studies have consistently described Hawaii as a diversity sink, prevailing currents likely offer opportunities for larval export. To assess interactions between the remote reefs of the Hawaiian Archipelago and the species-rich communities of the Central and West Pacific, we surveyed 14 nuclear microsatellite loci (nDNA, n = 857) and a 614 …

Material collected in summer 2004 from the Mid-Atlantic Ridge between Iceland and the Azores with three pelagic trawls was used to estimate relative catchabilities of common fish, cephalopod, decapod, and jellyfish species. Catchability is defined as the ratio of numbers caught between two trawls, standardized for towed distance. Taxon-specific catchability coefficients were estimated for two large pelagic trawls with graded meshes, using a smaller pelagic trawl with a uniform mesh size as the reference trawl. Two of the trawls were equipped with multiple opening-closing codends that allowed sampling of different depth layers. Generalized linear and mixed models suggest that most …
