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 …

Chesapeake Bay Fisheries: An Overview, Herbert M. Austin

VIMS Books and Book Chapters

The value of the marine resources of the Chesapeake Bay is second only to its value as a transportation corridor. The oyster, blue crab and striped bass or rock fish, along with the sailboat, epitomize our vision of the Bay. Nowhere else do such important renewable natural resources co-exist so closely to man's residential and industrial activities.

Over time, all natural resource distribution and abundance fluctuates in response to a normally fluctuating environment. Man's harvest adds an additional pressure, and in some cases recruitment levels cannot keep pace with consumer demand. In the Bay, pollutants, both intentional point source discharge, …

The American Oyster Crassostrea Virginica In Cheapeake Bay, Dexter Haven

VIMS Books and Book Chapters

The American Oyster (Crassostrea virginica) is widely distributed in Chesapeake Bay where it grows in the intertidal zone to depths of about 6.5 m. The salinity range over which it occurs, is from about 5 to 34 ° /oo. It is most abundant in protected embayments where bottoms are a firm sand-clay mixed with shelly material. This bivalve is a filter feeder, and ingests planktonic material which it strains from the water with its gills. Spawning occurs in Chesapeake Bay from June through September, and the eggs and resulting larvae are widely distributed during their 10-20 day planktonic life.

A Socio-Economic Overview Of The Chesapeake Bay Fisheries, James E. Kirkley

VIMS Books and Book Chapters

The marine resources of the Chesapeake Bay are believed to provide substantial benefit to residents of the State of Maryland and Virginia. However, the possibility of overfishing and degradation of the marine environment seriously jeopardizes the possible benefit . In thsi section, a brief overview of the economic importance and characteristics of the Chesapeake Bay marine resources is presented. The potential for economic lossee are discussed relative to observed economic values.

The Use Of Brewers Condensed Solubles In Bivalve Mariculture, David S. Gussman

Dissertations, Theses, and Masters Projects

Brewers Condensed Solubles (BCS), a by-product of the brewing industry, was evaluated as a nutrient source for rearing juvenile oysters (Crassostrea virginica) and clams (Mercenaria mercenaria). The BCS was used to culture bacteria which were fed to colorless flagellates which were in turn fed to the oysters and clams. The overall growth efficiency of oysters on BCS was 473 mg of oyster (whole weight) per g of BCS (dry weight). Fourteen isolates representing nine genera of bacteria were isolated from BCS enrichment cultures. Specific growth rates of the isolates at &24\sp\circ{lcub}\rm C{rcub}& on a BCS medium ranged from 0.48 &{lcub}\rm …

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.

Effect Of Air-Supersaturated Sea Water On Argopecten Irradians Concentricus (Say) And Crassostrea Virginica (Gmelin), Robert Bisker, Michael Castagna

VIMS Articles

Argopecten irradians concentricus and Crassostrea virginica were exposed to several different levels of supersaturated seawater at temperatures ranging from 10 to 2!°C. Gas bubble trauma occurred at a total gas saturation level of 116%, causing mortality in juvenile A. i. concentricus and reduced growth in juvenile C. virginica.

Comparative Attachment, Growth And Mortalities Of Oyster (Crassostrea Virginica) Spat On Slate And Oyster Shell In The James River, Virginia, D. S. Haven, J. M. Zeigler, J. T. Dealteris, J. P. Whitcomb

VIMS Articles

Slate was investigated as a substitute for oyster shells which are used as a substrate for oyster spat (Crassostrea virginica) settlement in James River, Virginia oyster repletion programs. Oyster shells and slate fragments were planted on adjacent plots in two submerged locations about 825 m apart in July 1984. Quantitative .093 m2 (one ft2) samples were collected by a diver on seven occasions through July 1985, with additional samples collected from teh natural oyster bottoms adjacent to the two areas. Percent mortality, growth and numbers of live spat and spat scars (dead spat) per unit area of bottom were determined. …
