The Vims Trawl Survey : Juvenile Atlantic Croaker, Brenda L. Norcross, Ginny H. Shaw Dec 1983

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.

The Density Of Oysters And Shell Upriver From The Campostella Bridge In The Elizabeth River, Dexter S. Haven, James P. Whitcomb Jun 1983

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 …

Energy Utilization In Bay Anchovy And Black Sea Bass Eggs And Larvae Contrasting Ecological Roles, John Wotring Tucker Jr Jan 1983

Energy Utilization In Bay Anchovy And Black Sea Bass Eggs And Larvae Contrasting Ecological Roles, John Wotring Tucker Jr

Dissertations, Theses, and Masters Projects

The objective of this study was a comparison of developmental changes and energy utilization in eggs, unfed larvae, and fed larvae of two marine fish species that both have pelagic early stages, but differ in phylogeny and early life ecology. The bay anchovy (Anchoa mitchilli), a clupeiform, spawns in estuaries and shallow coastal waters. The black sea bass (Centropristis striata striata), a perciform, spawns offshore at 15-50 m depths. Densities of zooplankton eaten by first-feeding fish larvae are normally higher in coastal waters than offshore. An important determinant of survival of larval fishes is their ability to fulfill nutritional requirements …

Chemical Induction Of Spawning By Serotonin In The Ocean Quahog Arctica Islandica (Linne), M. C. Gibbons, J. G. Goodsell, M. Castagna, R. Lutz Jan 1983

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 Jan 1983

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 …

Apagesoma-Edentatum, A New Genus And Species Of Ophidiid Fish From The Western North-Atlantic, Hj Carter Jan 1983

Apagesoma-Edentatum, A New Genus And Species Of Ophidiid Fish From The Western North-Atlantic, Hj Carter

VIMS Articles

A new genus and species of deep-sea fish, Apagesoma eden/alum, (family Ophidiidae), is described from deep waters off the Bahamas. It can be distinguished from other ophidiid genera by the following characters: an enlarged and swollen anterior nostril; eyes placed anteriorly on the head; moderate-sized, unsculptured, hemispheric-shaped sagitta; absence ofa basibranchial tooth patch; absence of an opercular spine; large sub-terminal mouth, with non-protrusible jaws. Typhlonus delosommalus Hureau et aI., 1979 is placed in Apagesoma based on similarities in otoliths, non-protrusibility of jaws, swollen anterior nostrils and absence of a basi branchial tooth patch. Typhlonus contains only the type species, T. …

Transport Of Bivalve Larvae In James River, Virginia, J. D. Andrews Jan 1983

Transport Of Bivalve Larvae In James River, Virginia, J. D. Andrews

VIMS Articles

For nearly 100 years, the James River has been the primary source of seed oysters for Virginia. A disease caused by Minchinia nelsoni (MSX) killed most oysters in high-salinity waters in the lower river in 1959 and 1960, and planting has not been resumed in these areas (Andrews 1983). Large populations of oysters on Hampton Bar and near the mouth of the river which served as broodstocks were destroyed. After 1960, setting declined drastically in regularity and intensity to about one tenth of that which occurred in the 1950's. Setting patterns suggest two types of seed areas in Chesapeake Bay: …
