Fishery Independent Standing Stock Surveys Of Oyster Populations In Virginia 1996, Roger L. Mann, James Wesson

Reports

Extensive description of the Virginia oyster resource and history of its utilization has been given by Haven, Hargis and Kendall (1981), and more recently reviewed by Hargis and Haven (1988). These contributions, among many others, describe a state of continuing decline. The James River, Virginia has served as the focal point for the Virginia oyster industry for over a century, being the source of the majority of seed oysters that were transplanted for grow-out to locations within the Virginia portion of the Chesapeake Bay and much further afield in the Middle Atlantic states (Haven et al, 1981 ). The Rappahannock …

Juvenile Fish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Volume 1995, Patrick J. Geer, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a trawl survey dating back to 1955. Over the years methods and objectives have varied according to funding sources and state and/or federal mandates. The present thrust of the program is to provide juvenile indices of relative abundance for recreationally, commercially, and ecologically· important fish and invertebrates. These measures of juvenile abundance are widely used as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of juveniles (age-0) have proven to be a reliable and early indicator of future year-class strength. A review of previously available …

Juvenile Finfish And Blue Crab Stock Assessment Program York River Random Stratified Bottom Trawl Survey Data Summary Report Volume R1989-1990, Michael F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. In the early 1970's, work was performed on the Mobjack Bay and Piankatank River using the standard 30 ft. fishing gear from a large research platform, with a 16 ft. gear towed from an outboard skiff or Chesapeake deadrise at shallow stations (:$; 12 ft.). Linda Pushee Mercer initiated the first random survey of the York River in 1971-72, as part of the results of a …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of The Chesapeake Bay : Annual Progress Report July 1995 - June 1996, Patrick J. Geer, Herbert M. Austin

Reports

Measures of juvenile abundance are presently in wide use as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of the relative interannual abundance of early juveniles (age-0) generated from scientific survey programs have been found to provide a reliable and early estimator of future year class strength (Goodyear 1985, Lipcius and Van Engel 1990). After a review of previously available indices of juvenile abundance for important fishery resource species in the Chesapeake Bay, the Chesapeake Bay Stock Assessment Committee (CBSAC), a federal/state committee sponsored and funded by the National Oceanic and Atmospheric Administration (NOAA), …

Juvenile Finfish And Blue Crab Stock Assessment Program York River Random Stratified Bottom Trawl Survey Data Summary Report Volume R1991-1994, Micheal F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. During the 1970's, the need for a random stratified survey of the main stem Bay and tributaries was realized and subsequently implemented. This program had a very large spatial coverage in various depth strata, but was very limited in its temporal component. Sampling occurred on a semi-annual basis primarily in January and February, and again in July (Wojcik and Van Engel, 1988a.) Based on previous results …

Population Structure Of The Arkshell Clams Noetia Ponderosa And Anadara Ovalis In The Oceanside Lagoons And Tidal Creeks Of Virginia And Implications For Fisheries Management, Kay A. Mcgraw, Michael Castagna, Sally D. Dennis

Reports

Two species of arkshell (blood) clams, Noetia ponderosa and Anadara ovalis, have · recently been targeted by watermen on the Eastern Shore of Virginia for sale to east coast markets. Until 1991 fishermen caught both species in conjunction with the harvest of oysters and hard clams and considered them of little value. Very little is known about either species, and preliminary data from our pilot study in 1993 indicated that blood clams were being overfished. In September, 1994 we conducted a survey in the oceanside lagoon system along the Eastern Shore and collected data on density, abundance, habitat preference, and …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 1995-December 1995 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a juvenile striped bass seine survey from 1967 through 1973 and from 1980 through the present. The primary objective has been the monitoring of the relative annual recruitment success of juvenile striped bass in the spawning and to the nursery areas of Lower Chesapeake Bay. Initially (1967-1973), the survey was funded by the U.S. Fish and Wildlife Service and when reinstated in 1980 with funding from the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey, support of the program has been jointly …

Development Of Age Determination Methods, Life History/Population Dynamics Information, And Yield-Per-Recruit Simulation Modeling To Evaluate The Potential For Growth And Recruitment Overfishing Of Weakfish, Cynoscion Regali, In The Chesapeake Bay, Mark E. Chittenden, Susan Lowerre-Barbieri, Cynthia M. Jones

Reports

The weakfish, Cynoscion regalis, supports large recreational fisheries in the Chesapeake Bay region, where it has historically shown large fluctuations in abundance. Although many studies have been conducted on this species in this region over the last 50 years or more, directed studies commencing at least as early as Nesbit (1954) and Massmann et al. (1958), little information has existed to support yield modeling and wise management. The present study was undertaken to provide basic life history/population dynamics information and yield modeling needed to wisely manage this species in the Chesapeake Bay region, and to evaluate the role that fishing …

Evaluation Of Dredge Fishing Activity On The Seaside Of Virginia's Eastern Shore, December 1994 - November 1995, Mark W. Luckenbach, James E. Wesson

Reports

Dredging has a long history in Virginia's commercial fisheries. In general, dredges are scraping or digging apparatuses that harvest as they are towed behind boats under power. Mechanical dredges have been used with sail power to harvest oysters since the mid- l 800's. Crabs have been harvested by power dredges since at least 1900, while dredge fishing of clams, which reside deeper in the substrate, began somewhat later. Individual crab dredges in Virginia can be a maximum of 8 ft wide and are usually pulled in pairs for a maximum total width of 16 ft. The dredge has a scraping …
