Oyster Spatfall In Virginia Rivers: 1987 Annual Summary, James Whitcomb

Reports

The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells is counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.

The 1987 Update On Leased Grounds Near The Us 17 Bridge Over Chuckatuck Creek, Roger L. Mann, James P. Whitcomb

Reports

This report is an update of a study made in June to mid-august 1979. This study was made by the Virginia Institute of Marine Science of the College of William and Mary for the Department of Highways and Transportation, Suffolk, Virginia. The previous study provided: 1) a description of the shellfish resource prior to construction of a new bridge; 2) an estimate of the value of the oysters and shell on leased areas within the right-of-way; and 3) a basis for a later study after construction to evaluate possible environmental changes.

Since 1979 the Commonwealth has purchased the right-of-way and …

Population Dynamics And Habitat Partitioning By Size, Sex, And Molt Stage Of Blue Crabs Callinectes Sapidus In A Subestuary Of Central Chesapeake Bay, Anson H. Hines, Romauld N. Lipcius, A. Mark Haddon

VIMS Articles

Abundances, size-frequency distributions, sexual composition and molt-stage composition of blue crabs Callinectes sapjdus were measured during 1983 to 1985 in the Rhode River, a subestuary of central Chesapeake Bay, USA. Crabs at the mouth and head of the river basin were sampled with monthly triplicate otter trawls. Crabs in the principal tidal creek of the river were sampled 3 d a week with a fish weir, which caught crabs moving upstream and downstream separately. Crabs exhibited consistent, marked seasonal cycles in abundance as well as considerable annual variation in July peak abundances. New recruits entered the subestuary in late fall …

Histopathological Analyses Of Tissue Sections Of The Eyes Of Indigenous Species Of Marine/Estuarine And Estuarine Fish, Willliam J. Hargis Jr.

Reports

The Elizabeth River is the most heavily settled and industrialized major subestuary in Virginia's Chesapeake System. Under increasing use and development since around 1610, its' waters have been exposed to all types of domestic, agricultural, military and industrial contaminants. ....Its sediments are contaminated by heavy metals, PAHs and all other introduced materials that accumulate and are stored there, with or without chemical transformation.... Collection of fish began in the Elizabeth River in the summer of 1982.

Study Of Alosa Stock Composition And Year-Class Strength In Virginia - Completion Report 1984-1986, Joseph G. Loesch, William H. Kriete Jr., Roxanne P. Trapani

Reports

This presentation is the completion report for P. L. 89-304, AFC 13-1-3 project "Study of Alosa stock composition and year-class strength in Virginia," for the period 1 January 1984 to 31 July 1986. The fishes of concern were the alewife (Alosa pseudoharengus), American shad (. sapidissima), and the blueback herring A. aestivalis).

The Physiography And Extent Of Public Oyster Grounds In Pocomoke Sound, Virginia., James P. Whitcomb, Dexter S. Haven

VIMS Articles

Public oyster grounds in Pocomoke Sound, Virginia, were charted in 1978 using an electronic positioning system to locate areas ~f oysters, shell, sand or mud. Over five thousand stations were occupied and 1,267 samples of the substrate were taken with hydraulically operated patent tongs. The information was used to draw large scale charts showing shorelines, depths, bottom types and out lines of public grounds. Substrates, elevations, slopes, oyster densities and spatfall levels were analyzed.

Predation On Single Spat Oysters Crassostrea Virginica (Gmelin) By Blue Crabs Callinectes Sapidus Rathbun And Mud Crabs Panopeus Herbstii Milne-Edwards, Robert Bisker, Michael Castagna

VIMS Articles

Single spat oysters Crassostrea virginica of four size classes (3.4-24.6 mm mean shell heights [SH]) were offered to six size classes of blue crabs Ca/linectes sapidus (9.3-85.5 mm mean carapace width [CW]) and five size classes of mud crabs Panopeus herbstii (7.1-34.4 mm mean CW) for 48 hr. Predation rate, recorded as the number of dead oyster spat/crab/day, was directly proportional to crab size and inversely proportional to oyster size. Mud crabs of 34.4 mm CW and blue crabs of 85 .5 mm CW had predation rates of 22.5 and 16.7 spat/crab/day on oyster spat of 24.6 and 24.4 mm …

A Comparison Of The Age And Growth Of The Tiger Shark, Galeocerdo-Cuvieri, From Off Virginia And From The Northwestern Gulf-Of-Mexico, Steve Branstetter, John A. Musick, James A. Colvocoresses

VIMS Articles

Lengths at age and growth rates for the tiger shark, Galeocerdo cuvieri. in the northwestern Atlantic and Gulf of Mexico were estimated from bands formed seasonally in the vertebral centra. The tiger shark grows rapidly compared with many other shark species. Growth rates for Gulf of Mexico juveniles were faster than for Atlantic juveniles. This produced significantly different (P < 0.01) estimates of the parameters of von Bertalanffy curves for the two regional samples. With sexes combined, parameter estimates for the Gulf of Mexico sample were L"" = 388 cm TL. K "" 0.184. to = -1.13 years; for the Atlantic sample they were L"" = 440 cm TL, K = 0.107, to = -2.35 years. Males mature at approximately 310 cm TL, females at 315-320 cm TL, but the regional differences in juvenile growth rates result in different ages at maturity. In the Gulf of Mexico. males mature in 7 years. females in 8 years; in the Atlantic. males and females both mature in approximately 10 years. The largest male and female examined (381 cm TL) were 15 and 16 years of age.
