Sailfish Habitat Utilization And Vertical Movements In The Southern Gulf Of Mexico And Florida Straits, David W. Kerstetter, Shannon M. Bayse, Jenny L. Fenton, John Graves
VIMS Articles
Pop-up satellite archival tags (PSATs) were deployed on 19 sailfish Istiophorus platypterus captured in the southern Gulf of Mexico and Florida Straits between 2005 and 2007 on commercial pelagic longline gear (n = 18) and recreational rod-and-reel gear (n = 1). The data from three tags indicated mortality events and were excluded from subsequent analyses. All PSATs were programmed to collect pressure (depth), temperature, and light-level data for 10 d at approximately 90-s intervals. These transmitted point data subsequently allowed the reconstruction of vertical movement patterns. The remaining 16 PSAT data sets indicate that sailfish are primarily associated with the …
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 …
Lessons Learned From Efforts To Restore Oyster Populations In Maryland And Virginia, 1990 To 2007, Vs Kennedy, Dl Breitburg, Mc Christman, Mark Luckenbach, Kennedy Paynter, J Kramer, Kevin Sellner, J Dew-Baxter, C Keller, Roger L. Mann

VIMS Articles
A century-long decline of the fishery for the Eastern oyster Crassostrea virginica (Gmelin, 1791) in Maryland and Virginia stimulated numerous efforts by federal, state, and nongovernmental agencies to restore oyster populations, with limited success. To learn from recent efforts, we analyzed records of restoration and monitoring activities undertaken between 1990 and 2007 by 12 such agencies. Of the 1,037 oyster bars (reefs, beds, or grounds) for which we obtained data, 43% experienced both restoration and monitoring, with the remaining experiencing either restoration or monitoring only. Restoration activities involved adding substrate (shell), transplanting hatchery or wild seed (juvenile oysters), bar cleaning, …
Genetic Diversity In U.S. Hatchery Stocks Of Crassostrea Ariakensis (Fujita, 1913) And Comparison With Natural Populations In Asia, Jie Xiao, Jan F. Cordes, Ja Moss, Kimberly S. Reece
Genetic Diversity In U.S. Hatchery Stocks Of Crassostrea Ariakensis (Fujita, 1913) And Comparison With Natural Populations In Asia, Jie Xiao, Jan F. Cordes, Ja Moss, Kimberly S. Reece
VIMS Articles
Although several different U.S. hatchery stocks of the Asian Suminoe oyster Crassosirea ariakensis were used in laboratory and field trials assessing performance, and in comparative studies with the native oyster Crassostrea virginica, the genetic composition of these hatchery stocks has not yet been examined comprehensively. Using eight microsatellite markers we investigated the genetic variability among five hatchery stocks and compared the genetic makeup of these stocks with 8 wild populations from Asia. Results showed significant genetic differentiation among the 5 hatchery stocks that was 6-fold larger than that observed among wild populations. A significant reduction in genetic diversity was observed …
Observations On The Early Life History And Growth Rates Of Juvenile Channel Whelks Busycotypus Canaliculatus (Linnaeus, 1758), Juliana Harding
Observations On The Early Life History And Growth Rates Of Juvenile Channel Whelks Busycotypus Canaliculatus (Linnaeus, 1758), Juliana Harding
VIMS Articles
Channel whelks (Busycotypus canaliculatus) were cultured from hatch through 171 days to describe the early life history and growth rates of juveniles. Whelks began to hatch at water temperatures of 15-18 degrees C. Channel whelks grew quickly from average shell lengths (SL) at hatch of 3.8 mm (SE = 0.1) to an average of 48.4 mm SL (SE = 1.3, n = 42 individuals) at 171 days post-hatch. The largest individual reached 53.2 mm SL, a gain of similar to 49.4 mm SL in 171 days, with a growth rate of 0.29 mm/day. Juvenile whelks readily consumed oyster (Crassostrea virginica) …
Cownose Ray (Rhinoptera Bonasus) Predation Relative To Bivalve Ontogeny, Robert A. Fisher, Garrett C. Call, Rochelle Grubbs
Cownose Ray (Rhinoptera Bonasus) Predation Relative To Bivalve Ontogeny, Robert A. Fisher, Garrett C. Call, Rochelle Grubbs
VIMS Articles
The purpose of this study was to determine the ability of the cownose ray, Rhinoptera bonasus (Mitchill, 1815), to manipulate oysters and clams, to test for relative prey preference, and to investigate whether susceptibility to cownose ray predation changes with bivalve ontogeny. We investigated patterns of predation for captive adult and young-of-year cownose rays on 4 species of bivalves, including Crassostrea virginica (Gmelin, 1791), Crassostrea ariakensis (Fujita, 1913), Mercenaria mercenaria (Linnaeus, 1758), and Mya arenaria Linnaeus, 1758. In oyster (C. virginica) trials, predation probabilities by adult rays were highest at shell heights of 30-70 mm and shell depths of 8-22 …

Performance Of Pop-Up Satellite Archival Tags, M. K. Musyl, M. L. Domeier, N. Nasby-Lucas, Richard Brill
VIMS Articles
Pop-up satellite archival tags (PSATs) are used to chronicle or 'archive' the habitat preferences, horizontal and vertical movements, fishery interaction, and post-release mortality rates of a variety of pelagic animals. Though PSATs are valuable research tools, lower-than-expected reporting rates, early detachment, and incomplete data return remain problematic. These issues were quantified by analysis of reporting rates, retention times (i.e. the time period PSATs remained attached), and the quantity of depth, temperature, and geolocation data returned from 731 PSAT deployments on 19 species in the authors' database and 1433 PSAT deployments on 24 species taken from 53 published articles. The reporting …

Escaping Paradise: Larval Export From Hawaii In An Indo-Pacific Reef Fish, The Yellow Tang Zebrasoma Flavescens, Jeff A. Eble, Robert J. Toonen, Laurie Sorenson, Larry V. Basch

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 …
