A Survey For Oysters And Shell In The Vicinity Of The Proposed Bridge Construction At The Site Of The Hampton Boulevard Bridge (Rte. 337) Over The Lafayette River In Norfolk, Va., Reinaldo Morales-Alamo, Roger L. Mann

Reports

At the request of the Virginia Department of Transportation (VDOT), the Virginia Institute of Marine Science (VIMS) conducted a survey of certain parcels of oyster grounds in the Lafayette River in the immediate vicinity of a proposed construction site for a new bridge across the river on Hampton Blvd., east of the present bridge, in Norfolk, Va.


Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1990-1991, James A. Colvocoresses, Patrick J. Geer Jun 1991

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1990-1991, James A. Colvocoresses, Patrick J. Geer

Reports

A recent analysis of the Virginia portion of the National Marine Fisheries Service Marine Recreational Fisheries Statistics Survey (VMRC 1985) showed that Virginia marine recreational catches were dominated by six species (spot, croaker, weakfish, black sea bass, summer flounder, and bluefish) which constituted over 85% of the total estimated catch by both numbers caught and weight landed. All of these species except bluefish heavily utilize the lower Chesapeake Bay as a nursery area for early juveniles which are highly vulnerable to bottom trawls.

Evaluation Of Spatial/Temporal Sources Of Variation In Nekton Catch And The Efficacy Of Stratified Sampling In The Chesapeake Bay : Final Report For Cbsac V To Chesapeake Bay Stock Assessment Committee And The National Marine Fisheries Service, Noaa, Mark E. Chittenden

Reports

Collections were made January through December 1988 using a 30 1 semiballoon trawl at 48 stations randomly selected each month, using equal allocation, from twelve geographical strata superimposed on a sampling frame of 16,730 possible stations uniformly distributed throughout water~ 12 feet deep in the Virginia mainstem Chesapeake Bay. The twelve geographical strata superimposed on the spatial sampling frame divided it into longitudinally-equal Upper, Middle and Lower Regions, each subdivided into four cross-bay regions, an Eastern Shore Littoral (12-30'), a Western Shore Littoral (12-30'), a Central Plain (30- 42'), and Deeps(> 42 1 ) .

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1990, Christopher F. Bonzek, Patrick J. Geer, James A. Colvocoresses, Robert E. Harris Jr. Mar 1991

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1990, Christopher F. Bonzek, Patrick J. Geer, James A. Colvocoresses, Robert E. Harris Jr.

Reports

This report summarizes data collected by the Virginia Institute of Marine Science (VIMS) monthly trawl survey cruises for January through December, 1990. 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 !fianagement 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 …

Oyster Spatfall In Virginia Waters: 1990 Annual Summary, Bruce J. Barber Feb 1991

Oyster Spatfall In Virginia Waters: 1990 Annual Summary, Bruce J. Barber

Reports

The Virginia Institute of Marine Science (VIMS) conducts surveys ofoyster spatfall (or "setting") in Virginia waters throughout the summer reproductive period. This survey provides an estimate of the potential of a particular area for receiving a "strike" or set of oysters on the bottom and helps define the timing of setting events. Information obtained from this effort is valuable to the Virginia Marine Resources Commission (VMRC) for its shell repletion program, and to private oyster growers, both of which are interested in maximizing the timing of shell planting. In addition, by maintaining a long-term data base, trends in spatfall throughout …

Increasing Angler Participation In Marine Catch/Tag-And-Release Fishing Programs: Workshop Summary, Program Outlines, And Angler Survey Results, Jon Lucy, Et Al Jan 1991

Increasing Angler Participation In Marine Catch/Tag-And-Release Fishing Programs: Workshop Summary, Program Outlines, And Angler Survey Results, Jon Lucy, Et Al

Reports

The three-part objective of this Sea Grant/National Marine Fisheries Service project was: (1) to examine anglers' experiences with tag-and release fishing programs; (2) to determine significant impediments, if any, to expanded participation in such programs as well as catch-and release fishing in general; and (3) to address anglers' concerns and questions about catch/tag-and-release fishing by developing educational material to promote greater participation in these activities and minimize fish mortalities due to improper tagging or release techniques.

Procedure For Creating Digital Baylor Coverages In Arc/Info, Gary F. Anderson, J. Berchman Smithson, Anna K. Kenne Jan 1991

Procedure For Creating Digital Baylor Coverages In Arc/Info, Gary F. Anderson, J. Berchman Smithson, Anna K. Kenne

Reports

Baylor Grounds were defined by a survey of the natural oyster beds in Virginia conducted by Lt. J.B. Baylor, USN, and completed in 1894. The original purpose of the survey was to set aside naturally productive oyster beds for protection from private leasing, which was a controversial concept at the time. Hence the commonly used term 'Baylor Grounds' is synonymous with Virginia's public oystering grounds in the present day. Other surveys, conducted later, have added to the original Baylor acreage, resulting in an estimated 243, 000 acres of public oyster grounds in Virginia. For further information on the oyster industry …


Striped Bass Research, Virginia: Characterization Of Virginia's Striped Bass Commercial Fisheries Annual Report 1991, Virginia Institute Of Marine Science Jan 1991

Striped Bass Research, Virginia: Characterization Of Virginia's Striped Bass Commercial Fisheries Annual Report 1991, 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 spring 1991 sampling period and compares the catchability of a multi-sized mesh anchor gill net with that of a pound net.

A Mark-Recapture Study Of Striped Bass In The James And Rappahannock Rivers, Virginia Annual Report 1990-1991, Joseph G. Loesch, Bruce W. Hill, Philip W. Sadler

Reports

A total of 1,903 striped bass were tagged in fall 1990 and 2,708 in spring 1991 on the Rappahannock River. A total of 2,405 striped bass were tagged in fall 1991 on the James River. In fall 1990, 47.2% of the striped bass tagged on the Rappahannock were less than 425 mm fork length (FL). In comparison, only 13.9% of the fish were less than 425 mm FL in spring 1991. Pound nets in the Rappahannock River accounted for 66.3% of the recaptures, while out of state recaptures accounted for only 2.65% of the total returns. In the fall 1990, …
