The Vims Trawl Survey : Juvenile Atlantic Croaker, Brenda L. Norcross, Ginny H. Shaw

Reports

An index of juvenile croaker recruitment was developed to test proposed relationships between juveniles and environmental factors. The VIMS trawl survey data base is unique on the east coast because of its duration and continuity. No other data set exists that samples the same species in the same locality with concurrent physical data over a long period of time.

Spectral Differences And Temporal Stability Of Phycoerythrin Fluorescence In Estuarine And Coastal Waters Due To The Domination Of Labile Cryptophytes And Stabile Cyanobacteria, Rj Exton, Wm Houghton, W Esaias, Lw Haas, D Hayward

VIMS Articles

Laser fluorosensing and epifluorescence microscopy were used jointly to identify the origin of different spectral peaks of phycoerythrin in estuarine and coastal samples. The fluorescence of the samples was also examined as a function of the time elapsed after a water circulation system was turned on. Coastal samples were dominated by cyanobacteria and exhibited a constant phycoerythrin fluorescence with time. The phycoerythrin fluorescence of the Chesapeake Bay estuarine samples first increased strongly, reached a maximum, and then decreased to below the original level; these samples were dominated by cryptophytes which epifluorescence techniques revealed were being destroyed by the circulation system. …

York River Slack Water Data Report : Temperature, Salinity, Dissolved Oxygen, 1971 - 1980, T. J. Brooks

Reports

The slack water survey program, provides an extended series of temperature, salinity, dissolved oxygen and nutrient measurements along the York River. These have been used to:

1) calibrate, verify, and update mathematical models; 2) provide a baseline against which effects of unusual events have been measured; and could be used to: 3) establish annual and longer period "climatological" trends in response to changing natural phenomena and man-made modifications to the estuary; 4) provide a basis against which fluctuations in biota could be compared.

This report contains station locations, survey schedules, field procedures, sample handling procedures, and data reduction and storage …

The Density Of Oysters And Shell Upriver From The Campostella Bridge In The Elizabeth River, Dexter S. Haven, James P. Whitcomb

Reports

This study estimates the density of oysters and oyster shells on that portion of the J. H. Miles Co. lease which lies within 450 feet of the upriver edge of the Campostella Bridge.

The Campostella Bridge is located on Route 460 on the Eastern Branch of the Elizabeth River (Figure 1). The area is restricted for shellfish culture by the Virginia State Health Department and salinities are high enough to favor the development of the oyster diseases Haplosporidium costalis (MSX) and Perkinsus marinum (Dermo). Because a combination of the effects of pollution and disease, the area has not produced commercial …

Seasonal-Variation In Survival Of Escherichia-Coli Exposed Insitu In Membrane-Diffusion Chambers Containing Filtered And Nonfiltered Estuarine Water, I. C. Anderson, Mw Rhodes, Hi Kator

VIMS Articles

Human fecal Escherichia coli isolates were exposed over a seasonal cycle to estuarine water in diffusion chambers filled with double-filtered (0.45 and 0.2 p.m) and nonfiltered water. Laboratory manipulations of E. coli cultures before estuarine exposure were reduced to minimize sublethal stress, and nonselective or resuscitative enumeration techniques were employed to maximize recovery of stressed cells. E. coli was capable of extended survival during in situ exposure to estuarine water, provided eucaryotes were excluded from diffusion chambers. Survival was directly related to temperature in absence of the eucaryote component of the natural microbiota. Although it was not possible to prevent …

Chemical Induction Of Spawning By Serotonin In The Ocean Quahog Arctica Islandica (Linne), M. C. Gibbons, J. G. Goodsell, M. Castagna, R. Lutz

VIMS Articles

Serotonin injected into the anterior adductor muscle induced spawning in the ocean quahog Arcrica islandica (Linne) when using either individual or mass spawning techniques. This represents the fir st successful attempt to induce the release of gametes in this species which historically has been unresponsive to conventional spawning stimuli. The gametes released were competent and fertilization occurred without treating the encapsulated eggs with ammonium hydroxide or other chemicals. Larvae were reared through metamorphosis to early juvenile stage.

The Origin And Extent Of Oyster Reefs In The James River, Virginia, Dexter S. Haven, James P. Whitcomb

VIMS Articles

The public oyster grounds (Baylor Survey Grounds) in the James River, VA, were studied with respect to bottom type and oyster density from 1978 to 1981. Approximately 10,118 ha (25,000 acres) were investigated using an electronic positioning system to establish station locations. Bottom types were determined using probing pipes, patent tongs, and an acoustical device. About 17.1% of the bottom was classified as consolidated oyster reef, and 47.5% was moderately productive mud-shell or sand-shell bottoms. The remaining 35.4% was rated as unsuitable for oyster culture. The surface configuration of oyster reef areas in the James River is similar to those …
