Statement On The Use Of Crassostrea Ariakensis In Chesapeake Bay, Virginia Institute Of Marine Science

Reports

In 1995 the Virginia General Assembly, through House Joint Resolution 450, directed the Virginia Institute of Marine Science (VIMS) to begin research on non-native oyster species for possible use in Chesapeake Bay. VIMS proceeded in a responsible manner by using sterile triploid oysters to prevent an unintended introduction. One of the results of our research has been the identification of an oyster species, Crassostrea ariakensis, that grows well in the Chesapeake Bay, is tolerant of local diseases, and has been well received in marketing trials. Recognizing that there is widespread commercial interest in this species, we are providing this statement …

Estimation Of Relative Abundance Of Recreationally Important Finfish In The Virginia Portion Of Chesapeake Bay: Annual Progress Report 2000-2001, Patrick J. Geer, Herbert M. Austin

Reports

Several annual indices of juvenile abundance have been generated from trawl survey data for 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). No species has shown a continuous trend during the past fourteen years under the present sampling scheme. However, several species have revealed declines (spot, scup, and northern puffer) or increases (striped bass) in recent years. Results for the 2000 sampling season indicate significant declines over …

Estimating Relative Abundance Of Young Of The Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of Chesapeake Bay, Patrick J. Greer

Reports

The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan for American Eel (FMP) in November 1999. The Plan focuses on increasing the states’ efforts to collect data on the resource and the fishery it supports through fishery dependent and independent studies. To this end, member jurisdictions (including Virginia) agreed to implement an annual abundance survey of young-of-year American eel (YOY). The survey is intended to “...characterize trends in annual recruitment of the young of the year eel over time [to produce a] qualitative appraisal of the annual recruitment of American eel to the U.S. Atlantic coast …

Estimating Relative Abundance Of Young Of Year American Eel, Anguilla Rostrata, In The Virginia Tributaries Of The Chesapeake Bay March 2000 - June 2001, Patrick J. Geer

Reports

Measures of juvenile recruitment success have long been recognized as a valuable fisheries management tool. In the Chesapeake Bay, these measures have provided reliable indicators for future year class strength for blue crabs (Lipcius and van Engel, 1990), striped bass (Goodyear, 1985), and several other recreationally important fishes (Geer and Austin, 1999).

The American eel, Anguilla rostrata, is a valuable commercial species along the entire Atlantic coast from New Brunswick to Florida. Landings along the U.S. Atlantic coast have varied from 290 MT in 1962 to a high of 1600 MT in 1975 (NMFS, 1999). In recent years there seems …

Variation In Top-Down And Bottom-Up Control Of Marine Bivalves At Differing Spatial Scales, Rochelle D. Seitz, Rom Lipcius

VIMS Articles

At large spatial scales(> 1 km). the forces structuring marine communities are diverse and include oceanographic, geological. and human processes, as well as availability of regional species pools. Few studies in marine and estuarine systems have examined the joint effects of predation (top-down) and food availability (bottom-up) in controlling populations at these scales. We compared the relative influence of top-down and bottom-up factors to population abundance of the infaunal clam Macomala balthican in two ecosystems differing in spatial extent by an order of magnitude. the York River, 50 km long, and the Rhode River. 5 km long. In both rivers, …

Status Of The Major Oyster Diseases In Virginia 2000 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson

Reports

As a consequence of the relatively warm temperatures, high salinities, and high oyster parasite abundances in the fall of 1999, both P. marinus and H. nelsoni were widely distributed throughout oyster populations in Virginia in 2000. Fortunately, however, we did not see severe epizootics of the diseases as observed in some areas in 1999.

Monitoring Relative Abundance Of American Shad In Virginia’S Rivers 2000 Annual Report, John E. Olney, John M. Hoenig

Reports

Since the moratorium, there have been no monitoring programs that provided direct assessment of stock recovery until this project began in 1998. The ban on in-river fishing in Virginia remained in effect, creating a dilemma for managers who needed reliable information in order to make a rational decision on when the in-river ban could safely be lifted. To address this deficiency, we proposed a method of scientific monitoring to estimate catch rates relative to those recorded before the prohibition of in-river fishing in 1994. This monitoring program began in 1998 and consisted of sampling techniques and locations that were consistent …

Food Habits Of Large Striped Bass In The Lower Chesapeake Bay And Its Tributaries March 1997 - May 1998, Herbert M. Austin, John F. Walter

Reports

Striped bass, Marone saxatilis, are dominant seasonal predators in Chesapeake Bay and support a large recreational and commercial fishery. This document presents the results of a yearlong ( 1997-1998) food habits study of large (> 450mm or 18 inches) striped bass in lower Chesapeake Bay and adjacent ocean waters. These fish comprise the coastal migratory stock and are found in greatest abundance in Chesapeake Bay during the spring and fall. Fish were obtained from a variety of commercial, recreational and fishery-independent sources and were captured by gill, fyke and pound nets as well as recreational hook and line, otter trawl …

Restoration Of The Oyster Resource In Chesapeake Bay: The Role Of Oyster Reefs In Population Enhancement, Water Quality Improvement And Support Of Diverse Species-Rich Communities, Roger L. Mann

VIMS Articles

Restoration of the oyster Crassostrea virginica resource to the Chesapeake Bay is a widely supported goal. The role of the oyster in restoration through benthic-pelagic coupling is examined in the context of current and projected watershed management problems, agricultural and urban development with associated nutrient and sediment erosion issues, in the entire Chesapeake Bay watershed. Efforts to date have focused on rebuilding three-dimensional reef structures, often with oyster broodstock enhancement, in predominantly small estuaries with retentive circulation to provide demonstration of increased resultant recruitment. Fishery enhancement activity is then based on local increases in recruitment. Such examples are used to …

A Study Of The Arkshell Clams, Noetia Ponderosa (Say 1822) And Anadara Ovalis (Bruguière 1789), In The Oceanside Lagoons And Tidal Creeks Of Virginia, Katherine A. Mcgraw, Michael Castagna, Loveday Conquest

VIMS Articles

Two species of arkshell (''blood'') clams. Noelia ponderosa and Anadara ova/is. have recently been targeted by watermen on the eastern shore of Virginia for sale to both East and West Coast markets in the United States. Until 1991. fishermen caught both species in the harvest of oysters and hard clams, and discarded them as bycatch with little value. Very little is known about either species of blood clam. and preliminary data from a pilot study in 1993 indicated that they were being over-fished. We conducted a survey in September 1994 in the oceanside lagoon system along the eastern shore of …

Fishing Skill In Developing Country Fisheries: The Kedah, Malaysia Trawl Fishery, K. Kuperan Viswanathan, Ishak Haji Omar, Yongil Jeon, James Kirkley, Et Al

VIMS Articles

Fishing skillis perceived to play a crucial role in catching fish. The
question arises for fishery managers as to whether or not there are observable
and measurable attributes of the skipper or vessel hat can be monitored and
regulated to account for skipper skill and, hence,this source of fishing capacity.
Equating technical efficiency with skipper skill, this paper evaluates technical
efficiency and skipper skill in the Kedah, Malaysia,trawl fishery to address this
issue.

Seasonal Occurrence And Site-Utilization Patterns Of Adult Tautog, Tautoga Onitis (Labridae), At Manmade And Natural Structures In Lower Chesapeake Bay, Michael D. Arendt, Jon Lucy, Thomas A. Munroe

VIMS Articles

Ultrasonic transmitters were surgically implanted into adult tautog (n=27,400-514 mm TL) to document seasonal occurrence and site utilization at four sites situated within known tautog habitat near Cape Charles, Virginia, in lower Chesapeake Bay. Tagged tautog were released at the same sites where originally caught within 2 h of capture. Sites were continuously monitored with automated acoustic receivers between 9 November 1998 and 13 October 1999. Two sites consisted of natural bedform. materials and two sites consisted of manmade materials. Ninety-four percent of tautog (n=15) released in fall 1998 remained inshore during winter at sustained water temperatures of 5-8 degreesC, …

A Comparison Of Calcified Structures For Aging Summer Flounder, Paralichthys Dentatus, Ann M. Sipe, Mark E. Chittenden

VIMS Articles

Calcified structures of summer flounder, Paralichthys dentatus, were evaluated to identify the best age determination method. Scales, the currently preferred structure, were compared with opercular bones and to right and left whole and sectioned otoliths for ages 0 to 10. All structures showed concentric rings that were interpreted as annual; however structures differed greatly in the clarity of their presumed annual marks. Right and left otoliths generally gave the same age, although they differed in the clarity of marks. Sectioned otoliths, particularly right ones, were the best aging structure. Right sectioned otoliths consistently showed the clearest marks and had the …

Aerobic Respiratory Costs Of Swimming In The Negatively Buoyant Brief Squid Lolliguncula Brevis, Ian K. Bartol, Roger L. Mann, Mark R. Patterson

VIMS Articles

Because of the inherent inefficiency of jet propulsion, squid are considered to be at a competitive disadvantage compared with fishes, which generally depend on forms of undulatory/oscillatory locomotion. Some squid, such as the brief squid Lolliguncula brevis, swim at low speeds in shallow-water complex environments, relying heavily on fin activity. Consequently, their swimming costs may be lower than those of the faster, more pelagic squid studied previously and competitive with those of ecologically relevant fishes. To examine aerobic respiratory swimming costs, O₂ consumption rates were measured for L. brevis of various sizes (2–9 cm dorsal mantle length, DML …

Criteria For Determining Maturity Stage In Female American Shad, Alosa Sapidissima, And A Proposed Reproductive Cycle, Je Olney, Sc Denny, Jm Hoenig

VIMS Articles

We describe macro- and microscopic criteria to judge maturation stages of female American shad (Alosa sapidissima) collected in the York river, Virginia, USA. For comparison, we also examined ovaries of fishes collected in the Edisto river, South Carolina, and the Connecticut river, Massachusetts. The study augments a developing stock assessment program that is evaluating the use of index-removal and change-in-ratio estimators of exploitation rate and absolute abundance. Samples were obtained from traps at the York river mouth, staked gill nets in mid-reaches of the river, and drift gill nets on the spawning grounds (approximately 100 km from the river mouth). …

Oyster Reefs As Fish Habitat: Opportunistic Use Of Restored Reefs By Transient Fishes, Juliana M. Harding, Roger L. Mann

VIMS Articles

Under the Magnuson-Stevenson Fisheries Management Act of 1996, current fisheries management practice is focused on the conce_pt of Essential Fish Habitat (EFH). Application of the EFH concept to estuarine habitats relates directly to ongoing oyster reef restorat10n efforts. Oyster reef restoration typically creates complex habitat in regions where such habitat is limited or absent. While healthy oyster reefs provide structurally and ecologically complex habitat for many other species from all trophic levels including recreationally and commercially valuable transient finfishes, additional data is required to evaluate oyster reef habitats in the context of essential fish habitat. Patterns of transient fish species …
