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 Aug 1988

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 ...


Comparison Of Condition Indicies (K) Of Spot (Leiostomus Xanthurus) From The Elizabeth And York Rivers, Virginia, Kinloch Nelson Aug 1988

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.

Comparative Analysis Of Sea Scallop Escapement/Retention And Resulting Economic Impacts, William D. Dupaul, Edward J. Heist, James E. Kirkley

Reports

During the months of June and September 1988, gear experiments were conducted aboard the F/V Carolina Dawn and Carolina Capes. The primary objective of the experiments was to assess the technical efficiency and size selectivity of 3.5-inch ring dredges relative to the current commercially-used 3.0-inch ring dredges. Secondary objectives were to analyze the economic and regulatory ramifications of using 3.5-inch ring dredges to control the age-at-capture and enhance the yield-per- recruit.


A Mark-Recapture Study Of Striped Bass In The Rappahannock River, Virginia Annual Report 1987-1988, Joseph G. Loesch, Bruce W. Hill, William H. Kreite Jr. Jan 1988

A Mark-Recapture Study Of Striped Bass In The Rappahannock River, Virginia Annual Report 1987-1988, Joseph G. Loesch, Bruce W. Hill, William H. Kreite Jr.

Reports

Internal anchor tags with external tubes were used to tag 3, 319 striped bass in the Fall of 1987 and 2,024 in the Spring of 1988 in the Rappahannock River. The total number tagged was adjusted to 3,170 and 1,973 by removing from consideration all fish that were at large less than a week. The available stock of striped bass in the Spring contained both young resident fish and mature nonresident fish which left the area of capture after spawning, presumably to migrate north in coastal waters. The exodus of the mature fish after spawning was responsible ...
