Reports

Oysters and mussels of varying sizes and sediment samples were collected from oyster beds with different salinity regimes of three Virginian coastal plain rivers: Rappahannock River. James River. and Piankatank River. Zinc concentrations of 1) soft tissues. gut contents. and shells of the oysters. 2) soft tissues of the mussels. 3) pea crabs. and 4) sediment samples were measured with a flame atomic absorption (Flame AA) spectrophotometer. Particulate organic carbon and nitrogen concentrations ·of the sediments were measured with a carbon-nitrogen analyzer. The contribution of extraneous materials. such as gut contents. faeces. and pea crabs. to the variability in oyster …

A Mark-Recapture Study Of Striped Bass In The Rappahannock River, Virginia Annual Report 1988-1989, Joseph G. Loesch, Bruce W. Hill

Reports

A total of 3,892 striped bass were tagged and released in the Fall 1988 and 1,316 fish in the Spring 1989 on the Rappahannock River.

In the Fall, 77.6% of the tagged striped bass were less than 400 mm FL. In contrast, 81.5% of the fish were 400 mm FL or greater in the Spring.

The available striped bass stock in the Fall is more vulnerable to fishing than is the available stock in the Spring. Recaptures per net day of tagged striped bass in pound nets in the Fall 1987 were seven times greater than in the Spring 1988, …

Striped Bass Research, Virginia - Annual Report 1987-88, Virginia Institute Of Marine Science

Reports

The research reported herein is directly in response to priorities established in the "Action Plan" of the Emergency Striped Bass Study (the Chafee Amendment (PL 96-118) of the Anadromous Fish Conservation Act (PL 89 -304 )) . The Amendment was the result of a decline in striped bass landings along the Atlantic Coast that began in the mid-1970's. The Virginia Institute of Marine Science (VIMS) had previously conducted a juvenile striped bass seining program from 1967 through 1973 which was discontinued at that point due to a loss of funding. The program was reinstated in 1980 with funding from the …

The Assessment Of Commercial Fishing Effort In Virginia Annual Report 1989, Joice S. Davis, James C. Owens, Joseph G. Loesch

Reports

This report summarizes an assessment of commercial fishing effort in the Chesapeake Bay and its Virginia tributaries during the period 1 October 1988 through 30 June 1989. Objectives of the study were: 1) to assess pound net fishing effort in Chesapeake Bay, in the James, York, Rappahannock, and Potomac rivers, and the Virginia tributaries to the Potomac River; and 2) to assess stake, anchor and drift gill net fishing effort in the James, York and Rappahannock rivers.

The study period began on 1 October 1988 and ended on 30 June 1989. Data for fyke net, haul seine and mullet net …

Reports

The basic objective of the study was to identify a core population of recreational fishermen owning private boats and fishing one or more Virginia artificial reefs or other popular wreck fishing sites (Figure land Table l) with some degree of regularity (making a minimum of two or three reef trips per season). This population of fishing boat owners would be sampled randomly, by either telephone or fishing log books, to determine fishing effort and catch rates characterizing trips made to specific reef and other popular wreck fishing sites during the 1987 fishing season. Examination of the resulting data would determine …

2. Determine the present status of the stocks relative to former yean; by comparison of landings and CPUE.

3. Estimate current biological statistics (age and size frequencies, species composition, etc.) of river herring and American shad.

Striped Bass Research, Virginia: Characterization Of Virginia's Striped Bass Commercial Fisheries Annual Report 1988-89, Bruce W. Hill, Joseph G. Loesch

Reports

The research reported herein (and in the 1982 through 1987 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 1988 and spring 1989 sampling period and compares these results with the previous work.

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 …

Oyster Spatfall In Virginia Rivers: 1988 Annual Summary, Bruce Barber, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts annual surveys of oyster spatfall ( or "sett.ing") in Virginia waters. This survey provides an estimate of the potential of a particular area for receiving a "striken or set of oysters and helps define the timiug of setting events. In 1988 spatfall was monitored from June 6 to October 16 at a total of forty-two stations (Figure 1). · During this period shellstrings were deployed at each station (0.5m off the bottom) on a weekly basis. A shellstring consists of 12 oyster shells drilled through the center and strung on a piece …

Experimental Studies Of Zinc-65 Uptake Rates By The American Oyster, Crassostrea Virginica With Regard To Salinity, Sediment Concentration, And Body Size, Cheol Mo, Bruce Neilson

Reports

Three sets of twelve oysters from the ,James River were placed in three recirculating aquaria dosed with the radioactive tracer zinc-65. All aquaria had the same amount of river bottom sediment which was kept in suspension by the water movement caused by aeration; one aquarium had twice as much tracer as the other two. The salinity of one of the low dose aquaria and. the high dose aquarium was maintained at 18 0/00: the other low dose aquarium was maintained at 1:2 0/00. All other factors were kept constant. Sediment-water-tracer mix was added to the aquaria every 12 hours. Water …

Comparison Of Condition Indicies (K) Of Spot (Leiostomus Xanthurus) From The Elizabeth And York Rivers, Virginia, Kinloch Nelson

Reports

Spot from the York and Elizabeth Rivers were taken in 1983, 1984, and 1985. The length to weight ratio was used to find the equation for Condition Index (K). Condition Indices for the two populations were found and plotted against temperature. Regression lines were plotted for each group. From 6 to 19 degrees, the Condition Index of the two populations rises at similar rates. From 19 degrees on, the Elizabeth River Condition Index rises steadily while the York K drops down to approach the levels of winter.
