Comparisons Of Gears And Vessels Used In The Virginia Institute Of Marine Science Juvenile Finfish Trawl Survey, David Hata

Reports

The Virginia Institute of Marine Science (VIMS) currently conducts a monthly trawl survey in the three major Virginia rivers and the lower Chesapeake Bay to estimate the abundance of economically important finfish species, particularly at the juvenile stage .. VIM:S has conducted similar trawl surveys in various forms since 1955. Although this represents a 40 year period, variations in sampling design and gear have confounded efforts to produce a meaningful, continuous time series. Such variations include changes in stations occupied, sampling frequency, _vessels, and trawl gears. Much of the trawl survey sampling has been documented (Wojcik and Van Engel 1988a, …

Effects Of Seagrass Biology On Water Quality In Shallow Regions Of The Lower Chesapeake Bay : Final Report, Kenneth A. Moore

Reports

The changes in water quality within shallow water regions of the lower Chesapake Bay was compared seasonally from permanent stations located along transects across vegetated and unvegetated sites in shoal regions of the lower Chesapeake Bay. The effect of the seagrass bed on conditions inside compared to outside of the bed varied seasonally and could be related to bed biomass and develoment. During spring (April-June) the rapidly growing seagrass bed was a sink for nutrients, suspended inorganic particles and phytoplankton, while during the summer, as bed dieback progressed, resuspension and release of nutrients were observed. Reductions in suspended particle concentrations …

Body Burden Of Polycyclic Aromatic Hydrocarbons And Tributyltin In Hard Clams, Mercenaria Mercenaria From The Elizabeth River, Va, Morris H. Roberts, Michael A. Unger

Reports

The Elizabeth River, contaminated with PAH, TBT, and heavy metals, is potentially home to a variety of estuarine invertebrates of commercial importance, notably oysters, hard clams, and crabs. Harvestable oysters have virtually disappeared from the system, but it has been rumored among commercial fishermen that a population of small (little neck to cherrystone) hard clams (Mercenaria mercenaria) exists within the Elizabeth River system. These clams are of serious interest to commercial clammers in the area as a previously unharvested source of market-size clams. Crabs of a harvestable size are also reasonably abundant throughout this river according to local fishermen.

Virginia Game Fish Tagging Program Annual Report 1996, Cm Bain Iii, John A. Lucy

Reports

The Virginia Game Fish Tagging Program (VGFfP), a cooperative project of the Virginia Marine Resources Commission and the Virginia Institute of Marine Science (VIMS), enjoyed its second full year of operation in 1996. Participation in the project, which is funded with revenues generated by Virginia's saltwater recreational fishing license, nearly doubled with 127 anglers volunteering as taggers compared to 64 in 1995.

Distribution Of Submerged Aquatic Vegetation In The Chesapeake Bay And Tributaries And The Coastal Bays - 1996, Robert J. Orth, Judith F. Nowak, David J. Wilcox, Jennifer R. Whiting, Leah S. Nagy

Reports

SA V distribution data in this report are presented and discussed based on the segmentation scheme adopted by the Chesapeake Bay Program (Flemer et al., 1983) and described briefly in the Methods section of this report. This zonation scheme (Upper, Middle, and Lower zones) for Chesapeake Bay, which accommodates the Chesapeake Bay Program segmentation boundaries, was adapted from that used in previous SAV distribution reports (i.e., Orth et al., 1994) and established by Orth and Moore ( 1982), then modified by Orth et al., ( 1989). The 1996 data were edgematched using ARC/INFO GIS software, as were all the historical …
