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