On-Board Quality Control Preparing Mid-Atlantic Fisheries For The Future, Robert A. Fisher
On-Board Quality Control Preparing Mid-Atlantic Fisheries For The Future, Robert A. Fisher
Reports
The U.S. population is eating more seafood than at any time in the nation's history. Strong national and local marketing and consumer education programs have encouraged this increased consumption. AF, consumers become more knowledgeable about seafood products, and as sales respond to competition, high quality products will be the 1ule rather than the exception. This guide focuses on the very beginning of quality assurance, on-board handling.
Areas of focus for on-board quality control measures include vessel sanitation, icing-temperature control, harvesting techniques, on-deck handling, and storage. These procedures, outlined on the following pages, are in line with preliminary requirements being set …
Estimation Of Standing Crop Of Oysters In The James River, Virginia, Using Commercial Fishing Records : Final Report, Bruce J. Barber, Roger L. Mann
Estimation Of Standing Crop Of Oysters In The James River, Virginia, Using Commercial Fishing Records : Final Report, Bruce J. Barber, Roger L. Mann
Reports
Virginia was the leading producer of oysters, Crassostrea virginica, as recently as the late 1950's, when landings of market oysters from the 243,000 acres of public grounds was about 700,000 bushels (Hargis and Haven, 1988). Beginning about 1960, a major decline in market oyster production occurred, principally the result of two oyster pathogens, Haplosporidium nelsoni (MSX) and Perkinsus marinus ( Dermo) . These pathogens have essentially decimated productive oyster grounds in the main stem of Chesapeake Bay as well as the lower portions of all the major rivers. Market oyster landings from public grounds had declined to 328,338 bushels in …

Heating Soft Crab Shedding Systems, Mike Oesterling
Heating Soft Crab Shedding Systems, Mike Oesterling
Reports
The molting of blue crabs, and ultimately soft shell crab production, is regulated by water temperature. A certain threshold or minimum water temperature must be reached before blue crabs begin to molt (shed). Although crabs begin shedding at temperatures in the mid-60'sF (18-19°C), water temperatures near 70°F (21°C) are optimum for active shedding. As the water temperature increases, the time required for a crab to progress through the stages leading to molting decreases (the time needed to go from a white-line, to a pink-line and finally red-line crab). The time needed for a complete molt--for a soft crab to exit …

Stock Identification Of Summer Flounder (Paralichthis Dentatus) In The Southern Mid-Atlantic Bight, John A. Musick, Joseph C. Desfosse, A. Deane Estes, Paul Lyons
Reports
A total of 12, 339 summer flounder were tagged from Virginia waters during 1987-89. A total of 874 were recaptured for an overall return rate of 7 . 1%. Most of the returns ( 48.5%) were from Virginia waters, or areas to the south. A smaller number ( 21.6%) were from areas north and offshore of Virginia. Another 29. 9% were recaptured and returned with inadequate location data. Examining only the returns with adequate location data, yielded a separation of 69.2% and 30.8% between the groups. No differences were noted in the sizes at tagging between these groups. Tagged flounder …

Reports
The Virginia Institute of Marine Science (VIMS) has conducted a juvenile striped bass seine survey during the years from 1967 through 1973 and from 1980 through the present, with the primary objective of monitoring the relative annual recruitment success of juvenile striped bass in the spawning and nursery areas of Lower Chesapeake Bay. The survey was funded during it's initial period by the U.S. Fish and Wildlife Service and then reinstated in 1980 with funding from the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey reported herein, support of the program …

Striped Bass Research, Virginia: Characterization Of Virginia's Striped Bass Commercial Fisheries Annual Report 1989-90, Virginia Institute Of Marine Science
Reports
The research reported herein (and in the 1982 through 1989 annual reports) is directly related to Priority III stated in the "Action Plan" (p. 15) of the Emergency Striped Bass Study (Anadromous Fish Conservation Act Amendment, Public Law 96-118). The amendment was the result of a decline in striped bass (Marone saxatilis) landings from Maine to North Carolina since the mid-1970's. This report summarizes the results of the fall 1989 and spring 1990 sampling period and compares these results with the previous work.

Mitochondrial Dna Restriction Fragment Length Polymorphism Analysis Of Weakfish (Cynoscion Regalis) Stock Structure Along The Mid-Atlantic Coast, Jan Mcdowell, Ana Beardsley, John Graves
Reports
To determine the genetic basis of intraspecifc population structure within the weakfish, cynoscion regalis, a total of 376 individuals was collected from four geographic sites along the midAtlantic coast of the United states for two success! ve years. Restriction fragment length polymorphism analysis of weakfish mitochondrial DNA with six restriction endonucleases demonstrated a low level of intraspecific mtDNA variation. The common restriction genotype occurred at a frequency of 0.88 to 0.95 in all samples, and there was no significant heterogeneity found in the frequency of occurrence of the combined rare variants among the samples. Furthermore, the temporal and spatial distribution …

Initial Information On The Atlantic Croaker : A Final Report On "Development Of Age Determination Methods, Life History - Population Dynamics Information, And Evaluation Of Growth Overfishing Potential For Important Recreational Fishes, Mark E. Chitteneden, Luiz R. Barbieri, Cynthia Jones, Et Al
Reports
Observational data on abundance of Atlantic croaker, Micropogonias undulatus, and boxes of specimens from which to obtain biological data for life history/population dynamics wor~ were collected at weekly or fortnightly intervals from Chesapeake Bay commercial :fisheries, primarily pound nets, in 1988 and 1989. A special collection of 24 boxes of one commercial grade was purchased from one fishery in 1989 to evaluate box-to-box variation in total lengths and sex ratios, and how it affects interpretation of routinely collected data. Length composition data from 25 years of York River trawling were used to compare length frequencies in trawl and pound net …

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Report Series Volume 1989, Patrick J. Geer, Christopher F. Bonzek, James Colcovoresses, Robert Harris Jr.
Reports
This report summarizes data collected by the Virginia· Institute of Marine Science (VIMS) trawl survey monthly cruises for January through December, 1989. The trawl survey is a long term, broad scope monitoring program. Its primary goal is to produce annual indices of juvenile (young-of-year) abundance of commercially, recreationally and ecologically important marine and estuarine finfish and crustaceans. The objective is to provide indices of sufficient accuracy and precision for both immediate resource management needs and long-term understanding of environmental influences on fishery resources. A second important product of this effort is the documentation and monitoring of habitat utilization by juveniles …
