Quantitative Assessment Of Fishing Mortality For Tautog (Tautoga Onitis) In Virginia : Preliminary Report, Geoffrey G. White, James E. Kirkley, Jon A. Lucy Dec 1997

Quantitative Assessment Of Fishing Mortality For Tautog (Tautoga Onitis) In Virginia : Preliminary Report, Geoffrey G. White, James E. Kirkley, Jon A. Lucy

Reports

Tautog (Tautoga onitis) have become a popular food and sport fish from Massachusetts to Virginia over the past ten years. Tautog are a long lived (30 years), late maturing (3-4 years), slow growing species. Although the maximum age recorded in Virginia is 31 years, recent studies have found that over 95% of the population is less than 12 years old (Hostetter and Munroe, 1993; White et aL, 1996). Adult tautog inhabit hard bottom wreck and reef environments, which are limited in Virginia's waters and are easily located and re-located by fishermen. Tautog are known to migrate inshore-offshore in New England …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of The Chesapeake Bay: Annual Progress Report 1996-1997, Patrick J. Geer, Herbert M. Austin Nov 1997

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of The Chesapeake Bay: Annual Progress Report 1996-1997, Patrick J. Geer, Herbert M. Austin

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 1988-1997. No species has shown a continuous trend during the nine 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 …


Evidence Of Widespread Destruction Of Submersed Aquatic Vegetation (Sav) From Clam Dredging In Chincoteague Bay, Virginia, Kenenth A. Moore, Robert J. Orth Oct 1997

Evidence Of Widespread Destruction Of Submersed Aquatic Vegetation (Sav) From Clam Dredging In Chincoteague Bay, Virginia, Kenenth A. Moore, Robert J. Orth

Reports

Beds of submerged aquatic vegetation (SAV) are important natural resources which are critical habitats for life stages of many commercially and recreationally important species of fish, crabs and shellfish in Virginia. SAV is comprised of rooted flowering plants which have historically grown throughout the Chesapeake Bay and Eastern Shore coastal lagoons in subtidal areas where water depths are less than 6 feet (Orth and Moore 1983). The presence of SAV in an area is indicative of water quality conditions which are low in nutrient enrichment and turbidity (Dennison et al. 1993). Given this relationship between water quality and growth, SAV …

Fishery Independent Standing Stock Surveys Of Oyster Populations In Virginia 1997, 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 River …

Reports

Recent fish kills and closures in the Pocomoke River have increased public concern over P.iesteda pjsddda, a microorganism that has been linked to large fish kills in North Carolina. In response to concerns about an unusual number of fish with lesions reported in Chesapeake Bay, especially the Pocomoke River, a Virginia Pfieste1iaTask Force was formed in May 1997. The Task force includes members of the Virginia Marine Resources Commission (VMRC), the Virginia Department of Health (VDH), the Virginia Department of Environmental Quality (DEQ), and research scientists from Virginia Institute of Marine Science (VIMS), and Old Dominion University (ODU).

An Investigation Into The Epizootiology Of Hematodinium Perezi, A Parasitic Dinoflagellate In The Blue Crab, Callinectes Sapidus : Final Report, Jeffrey D. Shields Jan 1997

An Investigation Into The Epizootiology Of Hematodinium Perezi, A Parasitic Dinoflagellate In The Blue Crab, Callinectes Sapidus : Final Report, Jeffrey D. Shields

Reports

Hematodinium perezi is a lethal parasitic dinoflagellate that lives in the hemolymph of brachyuran crabs. The parasite is found along the eastern seaboard of the USA where it occurs in epizootics in the commercially important blue crab, Callinectes sapidus. Crab mortalities associated with the disease occur in high salinity waters, typically in poorly draining estuaries. The parasite is prevalent in the seaside bays of the Delmarva Peninsula in the spring and fall, and spreads to the lower reaches of Chesapeake Bay in the fall. In October 1996, the prevalence of the disease along the Virginia portion of the Delmarva Peninsula …

Final Report For The Project Entitled A Stock Recruit Model Of The James River Oyster Fishery, Roger L. Mann, Eugene Burreson, David Evans, David Weiss

Reports

The James River, Virginia has served as the focal point for the Virginia oyster ( Crassostrea virginica) 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. It has been the site of continuing investigations of oyster distribution in relation to bottom type (Baylor 1894, Moore 1911, Loosanoff 1931, Marshall 1954, Haven at al. 1981a, Andrews 1982, Haven and Whitcomb 1983, Mann and Wesson unpublished data), spawning activity (Cox and Mann 1992, …


Parasitological Examination Of Wasting Disease In Black Abalone, Haliotis Cracherodii : Final Report, Jeffrey D. Shields, Frank O. Perkins Jan 1997

Parasitological Examination Of Wasting Disease In Black Abalone, Haliotis Cracherodii : Final Report, Jeffrey D. Shields, Frank O. Perkins

Reports

Black abalone in southern California are afflicted with chronic intestinal infections of a rickettsia-like organism that causes a debilitating and fatal withering syndrome. The hematology of withered animals indicated that cellular degradation and apoptosis occurred in tandem with the · decline and catabolism of abalone tissues. Two types of hemocytes were found in the hemolymph. Type I and Type II Hyalinocytes were distinguished by subtle differences in their cytoplasmic vesicles. Densities of both types of hemocytes declined in abundance, and small, presumptive stem cells increased in abundance with the progression of the disease. No circulating granulocytes were present in hemolymph; …

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 1996-December 1996 : Annual Progress Report, Herbert M. Austin, A. Dean Estes, Donald M. Seaver

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a juvenile striped bass seine survey from 1967 through 1973 and from 1980 through the present. The primary objective has been the monitoring of the relative annual recruitment success of juvenile striped bass in the spawning and to the nursery areas of Lower Chesapeake Bay. Initially (1967-1973), the survey was funded by the U.S. Fish and Wildlife Service and when reinstated in 1980 with funding from the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey, support of the program has been jointly …
