Fishery Independent Standing Stock Surveys Of Oyster Populations In Virginia 1995, Roger L. Mann, James Wesson

Reports

Extensive description of the Virginia oyster resource and history of its utilization has been given by Haven, Hargis and Kendall (1981), and more recently reviewed by Hargis and Haven (1988). These contributions, among many others, describe a state of continuing decline. The James River, Virginia has served as the focal point for the Virginia oyster industry for over a century, being the source of the majority of seed oysters that were transplanted for grow-out to locations within the Virginia portion of the Chesapeake Bay and much further afield in the Middle Atlantic states (Haven et al, 1981 ). The Rappahannock …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 1994-1995, Patrick J. Geer, Herbert M. Austin, David N. Hata

Reports

Annual indices of juvenile abundance have been generated from trawl survey data for several species of key recreational importance in the Virginia portion of Chesapeake Bay (spot, croaker, weakfish, summer flounder, black sea bass and striped bass, white and channel catfish) and four species of secondary importance (scup, white perch, northern puffer, and silver perch) for the period 1988-1995. No species has shown a continuous trend during the seven year period, although several species have revealed declines (spot, scup y-o-y white perch, northern puffer) or increases (Atlantic croaker and striped bass) in recent years. Spot has shown the largest decline …

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1994, Michael F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a trawl survey dating back to 1955. Over these forty years methods and objectives have varied according to funding sources and state and/or federal mandates. The present thrust of the program is to provide juvenile indices of relative abundance for recreationally, commercially, and ecologically important finfish and invertebrates. These measures of juvenile abundance are widely used as a key element in the management of the Atlantic States' coastal fishery resources. Estimates of juveniles (age-0) have proven to be a reliable and early indicator of future year-class strength. A review of previously …

Disease Processes And Transmission Dynamics Of Perkinsus Marinus In American Oysters (Crassostrea Virginia), Fu-Lin E. Chu

Reports

The once thriving oyster industry in the Chesapeake Bay and east coast of the United States, has been threatened by overfishing, and diseases caused by two protistan parasites, Haplosporidium nelsoni (MSX) and Perkinsus marinus (Dermo). Three lifestages are recognized in the lifecycle of P. marinus, meronts (trophozoites), prezoosporangia, and the biflagellated zoospores. The effects of the diseases caused by the two protists have been well documented (Andrews 1988, Barber et. al. 1988, Ford 1988, Ford and Figueras 1988, Chu et al 1993, Chu and LaPeyre 1993a, 1993b, Paynter and Burreson 1991). Since 1986, P. marinus has reportedly caused greater oyster …

Regulating The Blue Crab, Callinectes Sapidus, Fishery In Virginia : Biological And Economic Concerns, James E. Kirkley, William D. Dupaul, Michael J. Oesterling

Reports

The blue crab, Callinectes sapiclus, fishery has been one of the most important fisheries of Virginia. The importance of the fishery in terms of commercial activities has substantially increased in recent years in response to declining resource levels of American Oyster, Crassostrea virginica, and a growing international and domestic demand for soft crabs, female hard crabs, and crab meat.

The actual economic importance of the fishery, however, is not well known. For example, what are the employment and earning levels generated by the fishery? What portion of a waterman's household income is derived from crabbing? How much does crabbing contribute …

Field Studies In The Lynnhaven River For Calibration Of A Tidal Prism Water Quality Model, Kyeong Park, Albert Y. Kuo, Arthur J. Butt

Reports

Under the Virginia Coastal Resources Management Program Grants (VCRMPG) for FY '93, a tidal prism water quality model has been developed for small coastal basins and tidal creeks. The rationale of the model development is provided and the model is described in detail in Kuo & Park ( 1994). The tidal prism model uses the concept of tidal flushing for physical transport processes. The nutrient and phytoplankton kinetics are mostly from the Chesapeake Bay three-dimensional water quality model (Cereo & Cole 1994), and the model also includes the sediment process model of the main Bay (DiToro & Fitzpatrick 1993). The …

Clam Culture: The Possibilities And The Pitfalls, Michael J. Oesterling

Reports

Clam culture in-Virginia has recently received a ·great deal of attention due to the declining production of wild fishery stocks, and to the apparent success of some commercial clam farms. A 1994 survey of Virginia aquaculture by the Virginia Agricultural Statistics Service identified hard clams as the most valuable cultured product in the Commonwealth; production in 1993 exceeded $11 million in gross sales.

Be wary of reports that clam farming is easy and guarantees financial rewards. Farming clams is much more complicated than throwing clams overboard and returning a few years later to harvest them for market. The financial risks …
