Genetic Analysis Of White Marlin (Tetrapturus Albidus) Stock Structure, Je Graves, Jr Mcdowell Nov 2006

Genetic Analysis Of White Marlin (Tetrapturus Albidus) Stock Structure, Je Graves, Jr Mcdowell

VIMS Articles

The genetic basis of stock structure of white marlin (Tetrapturus albidus Poey, 1860) was inferred from analyses of five tetranucleotide repeat microsatellite loci (n = 214) and the mitochondrial (mt)DNA control region (n = 99) of white marlin from four geographic regions in the Atlantic Ocean. Considerable genetic variation was present in all collections for all molecular markers. Analysis of replicate collections taken in different years from three regions revealed no significant differences in the distribution of allele frequencies among years within regions. The value of global F-statistics for both multilocus microsatellite data and mtDNA control region sequences approached significance (0 ...

Phylogeny Of Recent Billfishes (Xiphioidei), Bb Collette, Jr Mcdowell, Je Graves Oct 2006

Phylogeny Of Recent Billfishes (Xiphioidei), Bb Collette, Jr Mcdowell, Je Graves

VIMS Articles

Billfishes are genetically and morphologically distinct enough from scombroids to merit placement in a separate suborder, Xiphioidei. Two extant families are usually recognized: Xiphiidae (swordfish, Xiphias) and Istiophoridae, currently containing three genera, Istiophorus (sailfishes), Makaira (marlins), and Tetrapturus (spearfishes, white, and striped marlins). Phylogenetic analyses of molecular data from mitochondrial and nuclear gene sequences (mitochondrial control region, ND2, 12S, and nuclear MN 32 regions) show a different picture of relationships. Makaira is not monophyletic: blue marlin cluster with sailfish and placement of black marlin is unstable. Accepting the molecular phylogeny gives two possible classifications: (1) two genera: blue marlin + sailfish ...

Detection Of Panulirus Argus Virus 1 (Pav1) In The Caribbean Spiny Lobster Using Fluorescence In Situ Hybridization (Fish), Cw Li, Jd Shields, Hj Small, Ks Reece, Et Al

VIMS Articles

Panulirus argus Virus 1 (PaV1) is the first virus known to be pathogenic to a wild lobster. It infects the Caribbean spiny lobster P. argus from the Florida Keys, and has a predilection for juveniles. The monitoring of the virus in wild populations and study of its behavior in the laboratory require the development of reliable diagnostic tools. A sensitive and specific fluorescence in situ hybridization (FISH) assay was developed for detection of PaV1. The lower detection limit using a 110 bp DNA probe in a dot-blot hybridization for PaV1 DNA was 10 pg of cloned template PaV1 DNA and ...

Final Report Chesapeake Bay Trophic Interactions Laboratory Services (Ctils), Debra Parthree, Christopher F. Bonzek, Robert J. Latour

Reports

Stomach samples or whole fish were obtained from a network of up to eight participating fisheries surveys in the Chesapeake Bay area. Field supplies and sample transport were provided by CTILS. Whole fish were processed for length, weight, and sex determination. Stomachs were removed and analyzed in the laboratory and prey types determined. In support of ecosystem-based fisheries management, estimates of locationspecific diet composition were produced for each species. Comparisons of dietary habits of each species among a range of habitats in the Bay and throughout various time frames were made.

Estimating Relative Abundance Of Young Of Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay (Spring 2005), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (hereafter referred to as FMP) for the American eel in November 1999. The FMP focuses on increasing coastal states’ efforts to collect American eel data through both fishery dependent and fishery independent studies. Consequently, member jurisdictions (including Virginia) agreed to implement an annual survey for YOY American eels. The survey is intended to “…characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic Coast” (ASMFC, 2000). The development of ...

Status Of The Major Oyster Diseases In Virginia 2005 A Summary Of The Annual Monitoring Program, Ryan B. Carnegie, Eugene M. Burreson Jul 2006

Status Of The Major Oyster Diseases In Virginia 2005 A Summary Of The Annual Monitoring Program, Ryan B. Carnegie, Eugene M. Burreson

Reports

More normal riverflows and salinities returned in 2005 after two very wet years. Temperatures were somewhat colder than normal during the winter, and warmer during the summer. The physical environment was generally more favorable for parasite activity, and thus brought a slight increase in prevalence and intensity of the oyster diseases caused by Perkinsus marinus (Dermo) and Haplosporidium nelsoni (MSX). Among quarterly James River Survey sites, maximum annual P. marinus prevalences returned to levels typical of the mid- 1990s, before the years of drought. P. marinus prevalence reached 92% at Wreck Shoal, 56% at Point of Shoal, 68% at Horsehead ...


Genetic Heterogeneity Of Atlantic Bluefin Tuna Caught In The Eastern North Atlantic Ocean South Of Iceland, J Carlsson, Jr Mcdowell, Et Al Jul 2006

Genetic Heterogeneity Of Atlantic Bluefin Tuna Caught In The Eastern North Atlantic Ocean South Of Iceland, J Carlsson, Jr Mcdowell, Et Al

VIMS Articles

Atlantic bluefin tuna (Thunnus thynnus) are currently managed by the member nations of the International Commission for the Conservation of Atlantic Tunas (ICCAT) as distinct western and eastern stocks, separated by the 45 degrees W meridian. Previous studies of Atlantic bluefin tuna caught in the northeast Atlantic south of Nor-way suggested mixing of putative stocks in the region, based on abrupt shifts in the size and condition of fish during the fishing season. By contrast, more recent studies south of Iceland reported only small differences in size of tuna caught at different times of the season in that area. To ...

Evaluating Recruitment Of American Eel, Anguilla Rostrata, To The Potomac River (Spring 2006), Marcel M. Montane, Wendy A. Lowery, Hank Brooks, Aimee D. Halvorson

Reports

Fisheries management techniques are not often applied to American eels because basic biological information is not well known. Unknown biological parameters such as variation in growth rates and length at age have complicated stock assessment and management efforts. Though American eel are not usually considered a sport fish, their ubiquity and readiness to take a bait leads them to be caught by recreational fishermen (Collette and Klein-MacPhee, 2002). Young American eel are also used as a baitfish in coastal areas (Jenkins and 4 Burkhead, 1993.) Absence of basic population dynamics data has hampered attempts at evaluation of regional exploitation rates ...

Virginia Shellfish Aquaculture Situation And Outlook Report : Results Of The 2004-2006 Virginia Shellfish Aquaculture Crop Reporting Survey, Thomas J. Murray, Michael J. Oesterling

Reports

Growth of the shellfish aquaculture industry in Virginia has added significant value to the state’s seafood marketplace. Today, watermen continue to harvest both hard clams and oysters from the state’s public resources, albeit at diminished rates. At the same time, Virginia’s watermen-farmers are providing growing quantities of additional quality shellfish to consumers. Following the lead of the hard clam industry, there has been a significant transition to intensive aquaculture of native oysters in recent years. The once extensive oyster planting has disappeared primarily as a result of endemic oyster diseases and increasing wildlife predation of seed oysters ...

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2005 Annual Report, John E. Olney, Kristen A. Delano Apr 2006

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2005 Annual Report, John E. Olney, Kristen A. Delano

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio ...

Incentive-Based Approaches To Sustainable Fisheries, Rq Grafton, R Arnason, Et Al, Je Kirkley, Et Al Mar 2006

Incentive-Based Approaches To Sustainable Fisheries, Rq Grafton, R Arnason, Et Al, Je Kirkley, Et Al

VIMS Articles

The failures of traditional target-species management have led many to propose an ecosystem approach to fisheries to promote sustainability. The ecosystem approach is necessary, especially to account for fishery-ecosystem interactions, but by itself is not sufficient to address two important factors contributing to unsustainable fisheries: inappropriate incentives bearing on fishers and the ineffective governance that frequently exists in commercial, developed fisheries managed primarily by total-harvest limits and input controls. We contend that much greater emphasis must be placed on fisher motivation when managing fisheries. Using evidence from more than a dozen natural experiments in commercial fisheries, we argue that incentive-based ...

Liver Carcinogenesis In A Non-Migratory Fish: The Association With Polycyclic Aromatic Hydrocarbon Exposure, W. K. Vogelbein, M. A. Unger

VIMS Articles

Field and laboratory studies indicate a strong positive association between exposure to chemical pollutants in aquatic environments and development of neoplasia in fishes. This brief communication reviews some of the more important North American and European studies that have been conducted on this relationship. We then review work conducted on a small nonmigratory estuarine cyprinodontid teleost fish, the mummichog (Fundulus heteroclitus) in the industrialized Elizabeth River, Virginia USA. Histopathological surveys of mummichogs from variously degraded habitats indicate an association between PAH exposure and development of neoplasia. We have observed non-neoplastic lesions, preneoplasms and hepatic, biliary, exocrine pancreatic and vascular neoplasms ...
