Biology And Distribution Of Species Of Polyacanthonotus (Pisces, Notacanthiformes) In The Western North-Atlantic, Re Crabtree, Kj Sulak, Ja Musick Jan 1985

Biology And Distribution Of Species Of Polyacanthonotus (Pisces, Notacanthiformes) In The Western North-Atlantic, Re Crabtree, Kj Sulak, Ja Musick

VIMS Articles

The notacanthid genus Poiyacanthonotus is represented in the Atlantic by three species of demersal deep-sea fishes at depths from about 500-3,800 m. Recent collections have made available new material from the temperate and tropical western North Atlantic for life history study of P. merretti and P. rissoanus. Species of the genus are browsers on small benthic macrofauna including polychaetes, gammaridean amphipods, and mysids. Reproduction does not appear to be seasonal. Fecundity is positively correlated with size in P. merretti, and ranges between 1,900-5,700 ova. Fecundities are much higher (ca. 20,000-30,000 ova) in P. rissoanus and P. cha/lengeri, which attain a …


Monomitopus-Magnus, A New Species Of Deep-Sea Fish (Ophidiidae) From The Western North-Atlantic, Hj Carter, Dm Cohen Jan 1985

Monomitopus-Magnus, A New Species Of Deep-Sea Fish (Ophidiidae) From The Western North-Atlantic, Hj Carter, Dm Cohen

VIMS Articles

Monomitopus magnus new species is described from slope waters off the southeastern coast of North America. M. magnus is most closely related to M. american urn from the continental slope of Uruguay and southern Brazil and is more distantly related to the western Pacific M. pallidus. M. magnus differs from M. americanum in having fewer developed gill rakers on the anterior arch (10-11 compared to 14-22) and more precaudal vertebrae (15 compared to 13-14). The 13 nominal species of Monomitopus are divided into three groups based on head shape and degree of ossification.


Distribution Of Demersal Fishes Of The Caribbean Sea Found Below 2,000 Meters, Me Anderson, Re Crabtree, Hj Carter, Et Al Jan 1985

Distribution Of Demersal Fishes Of The Caribbean Sea Found Below 2,000 Meters, Me Anderson, Re Crabtree, Hj Carter, Et Al

VIMS Articles

Abyssal fishes of the Caribbean Sea are known from the work of six research vessels, yet only one ofthese collections has been reported. The most recent collection, that of the USNS BARTLETTin 1981, contains 13 new records of rare fish to the Caribbean, including two undescribed species. Twelve species accounts are given, documenting the new finds, along with some taxonomic changes from previous reports. Zoogeographical analysis revealed that the abyssal fish fauna of the Caribbean basins reflects a depauperate, tropical, western Atlantic subunit of a broader, circumglobal pattern of the world's abyssal fish fauna.


The Effects Of Seed Size, Shell Bags, Crab Traps, And Netting On The Survival Of The Northern Hard Clam Mercenaria Mercenaria (Linne), John N. Kraeuter, Michael Castagna Jan 1985

The Effects Of Seed Size, Shell Bags, Crab Traps, And Netting On The Survival Of The Northern Hard Clam Mercenaria Mercenaria (Linne), John N. Kraeuter, Michael Castagna

VIMS Articles

Seed size at planting is the dominant factor affecting hard clam survival to marketable size when field grow-out techniques are used. The use of plastic mesh nets, crab traps, and wire mesh bags (filled with oyster shells) alone or in combination can be used to increase survival of hard clams of ~ 6 to 8-mm shell height. These techniques do not provide sufficient protection for 2-mm seed. The combination of net + crab trap + shell bag was nearly twice as effective as the net alone when 10 to 14-mm seed was used and over five times as effective as …

Striped Bass Research, Virginia - Annual Report 1985, Virginia Institute Of Marine Science

Reports

The research reported herein is directly in response to priorities established in the "Action Plan" of the Emergency Striped Bass Study (the Chafee Amendment (PL 96-118) of the Anadromous Fish Conservation Act (PL 89- 304)). The Amendment was the result of a decline in striped bass landings i along the Atlantic Coast that began in the .mid-1970's. The Virginia Institute of Marine Science (VIMS) had previously conducted a juvenile striped bass seining program from 1967 through 1973 which was discontinued at that point due to a loss .of funding. The program was reinstated in 1980 with funding from the National …

Abundance, Seasonality And Community Structure Of Fishes On The Mid-Atlantic Bight Continental Shelf, James Alden Colvocoresses

Dissertations, Theses, and Masters Projects

Cluster analyses of seasonal (spring and fall) National Marine Fisheries Service Groundfish Survey bottom trawl catches on the Middle Atlantic Bight continental shelf revealed consistent species associations and faunal zones over a nine year period during. Boundaries between faunal zones tended to follow isotherms on the inner portions of the shelf and isobaths along the outer shelf. During the late winter/early spring, four faunal zones were identified: a northern inner and middle shelf zone extending from Cape Cod southward to about Delaware Bay, a northern middle and outer shelf zone offshore of the first zone, a southern middle and outer …


Norfolk Canyon Marine Sanctuary Resources Study Plan : Final Report, Virginia Institute Of Marine Science Jan 1985

Norfolk Canyon Marine Sanctuary Resources Study Plan : Final Report, Virginia Institute Of Marine Science

Reports

Establishment of a Norfolk Canyon Marine Sanctuary provides the framework necessary to examine the biological, geological, and hydrographic processes functioning in submarine canyon systems and to improve the basis for management decisions related to exploitation of East Coast submarine canyons.

Research in submarine canyons is not an easy task. Although there are nearly 100 submarine canyons between Cape Hatteras and Nova Scotia, Norfolk Canyon, the canyon closest to the coast, is approximately 100 km from the nearest landfall. The Canyon begins at about the 80-100 m isobath contour and extends to a depth of more than 2000.


Energy Utilization Model For Silver Perch, Bairdiella Chrysoura (Bioenergetics, Sciaenidae, Growth, Eelgrass, Chesapeake Bay), Hugh Anthony Brooks Jan 1985

Energy Utilization Model For Silver Perch, Bairdiella Chrysoura (Bioenergetics, Sciaenidae, Growth, Eelgrass, Chesapeake Bay), Hugh Anthony Brooks

Dissertations, Theses, and Masters Projects

An energetics model was constructed as an alternative method to length frequency analysis for the estimation of growth for juvenile silver perch, Bairdiella chrysoura. The model approach was adopted since estimation of juvenile estuarine fish growth by only collecting length or weight frequency data is difficult due to the large bodies of water and variety of microhabitats that must be regularly sampled over short time intervals. Field and laboratory data was included in analysis of model compartments for growth, metabolism, food intake and energy loss in waste products. Food habit studies indicated that silver perch is a planktivore that feeds …

Dissertations, Theses, and Masters Projects

Numerical classification analyses (clustering) of spring, summer and fall National Marine Fisheries Service bottom trawl catches on the inshore continental shelf between Cape Ann, Ma. and Cape Fear, N.C., showed consistent species associations and faunal zones over a three year period. Analysis of a data set created by combining all nine survey cruises also produced consistent species associations, however sites clustered by seasons as well as by geographic area. The three faunal provinces of the U.S. east coast (Gulf of Maine, Middle Atlantic Bight and South Atlantic Bight) were represented in the study area, as were the seasonal faunal barriers …


A Bioeconomic Model Of The Middle Atlantic Surf Clam (Spisula Solidissima) Fishery, Thomas M. Armitage Jan 1985

A Bioeconomic Model Of The Middle Atlantic Surf Clam (Spisula Solidissima) Fishery, Thomas M. Armitage

Dissertations, Theses, and Masters Projects

A bioeconomic simulation model of the middle Atlantic surf clam (Spisula solidissima) fishery has been developed from a survey of biological and econometric relationships. While identifying the biological input parameters available in the literature, the economic submodel of the fishery has been developed with price and landings time series data, and with data obtained through the use of survey questionnaires and interviews with surf clam fishermen and processors. Alternative management scenarios in the fishery have been evaluated from industry costs in both the harvesting and processing sectors and analysis of the demand for raw product confronting surf clam fishermen. Multiple …

Evaluation Of The Toxicity Of Contaminated Sediments In The James River, Virginia, Morris H. Roberts, Charles J. Strobel

Reports

The Virginia State Water Control.Board, in cooperation with the Department of Chemical Oceanography of the Virginia Institute of Marine Science has recently conducted periodic chemical surveys of organic pollutants in the sediments of the upper James River. The August 1983 survey showed elevated concentrations of polycyclic aromatic hydrocarbons (PAH) at Stations ·4 and 7 (Figure 1 and Table 1). Although the reported concentrations were approximately one order· of magnitude lower than those reported in contaminated areas of the Elizabeth River, they were deemed high enough to warrant_ further study based on reported toxicity of Elizabeth River sediments (Hargis et al. …
