he relationship of potential defense-related cellular and humoral activities and the sus- ceptibility of eastern oysters Crassostrea virginica to the parasite Perkinsus marinus were examined at 10, 15, 20 and 25 "C. Oysters were acclimated at experimental temperatures for 20 d and then chal- lenged with R marinus. Total hemocyte counts (TC) and percentage of granulocytes (PG) 20 d after temperature acclimation were higher in oysters at high than at low acclimation temperature. Higher protein (P) and lysozyme (L) concentrations were found in oysters at 10 and 15 "C. No significant differ- ences in hemagglutination (H) titers due to temperature …

Juvenile Finfish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Series Volume 1992, Christopher F. Bonzek, Patrick J. Geer, James A. Colvocoresses, Robert E. Harris
Reports
This report summarizes data collected by the Virginia Institute of Marine Science (VIMS) monthly trawl survey cruises for January-December 1992. The trawl survey is a long term, broad scope monitoring program. Its primary goal is to produce annual indices of juvenile (young-of-year) abundance of commercially, recreationally and ecologically important marine and estuarine finfish and crustaceans. The objective is to provide indices of sufficient accuracy and precision for both immediate resource management needs and long-term understanding of environmental influences on fishery resources. A second important product of this effort is the documentation and monitoring of habitat utilization by juveniles and smaller …

Phylogeny Of Lampridiform Fishes, Je Olney, Gd Johnson, Cc Baldwin
VIMS Articles
A survey of characters defining the Neoteleostei, Eurypterygii, Ctenosquamata, Acanthomorpha, Paracanthopterygii and Acanthopterygii convincingly places the Lampridiformes within the acanthomorph clade. Lampridiforms are primitive with respect to the Percomorpha but their precise placement among basal acanthomorphs remains unclear. In the absence of a specific sister-group hypothesis, Polymixia, percopsiform and beryciform taxa were used as outgroups in a cladistic analysis of the order. Monophyly of Lampridiformes is supported by four apomorphies; three are correlated modifications related to the evolution of a unique feeding mechanism in which the maxilla slides forward with the premaxilla during jaw protrusion. The Veliferidae are the sister …
Identification And Distribution Of Urophycis And Phycis (Pisces, Gadidae) Larvae And Pelagic Juveniles In The United-States Middle Atlantic Bight, Bruce H. Comyns, George C. Grant
Identification And Distribution Of Urophycis And Phycis (Pisces, Gadidae) Larvae And Pelagic Juveniles In The United-States Middle Atlantic Bight, Bruce H. Comyns, George C. Grant
VIMS Articles
Analysis of surface and subsurface plankton collections in the Middle Atlantic Bight (MAB) yielded larvae and juveniles of Phycis chesteri and five species of Urophycis. Identification was based on numbers of epibranchial gill rakers, abdominal vertebrae, and. fin rays (dorsal, caudal, pelvic), patterns of pterygiophore interdigitation, and morphometric characters including body depth at the vent and a ratio between height of the pelvic-fin base and length of the mandible. Urophycis tenuis accounted for 99% of the Urophycis larvae and pelagic juveniles collected during spring off Virginia and New Jersey and was most abundant offshore. Urophycis tenuis larvae were smallest at …
Age, Growth, And Reproduction Of Tautog Tautoga-Onitis (Labridae, Perciformes) From Coastal Waters Of Virginia, E. Brian Hostetter, Thomas A. Munroe
Age, Growth, And Reproduction Of Tautog Tautoga-Onitis (Labridae, Perciformes) From Coastal Waters Of Virginia, E. Brian Hostetter, Thomas A. Munroe
VIMS Articles
Tautog Tautoga onitis are gaining popularity in Virginia's coastal waters as a recreational and food fish. Adult tautog are seasonally abundant on inshore hard-bottom habitats (1-10 m) and inhabit offshore areas (10-75 m) year-round. Juveniles, especially newly-settled recruits, inhabit vegetated areas in shallow water (usually < 1 m). From March 1979 to July 1986, tautog were collected in lower Chesapeake Bay and nearby coastal waters to examine age, growth, and sexual maturation. Age estimates were determined from annular marks on opercle bones: 82% of the fish were age-10 or younger, 18% exceeded age-10, and 1% were age-20 or older. Marginal increment analysis revealed that annuli formed concurrent with a protracted spawning season (April-July). The von Bertalanffy growth equation, derived from back-calculated mean lengths-at-age, was l(t) = 742 [1-e-0.085 (t-1.816)]. Tautog are long-lived (25+ yr) and attain relatively large sizes (672 mm TL) slowly (K for sexes combined = 0.085). Growth rates of both sexes are similar, although males grow slightly faster (K = 0.090 vs. 0.085 for females). Maturity occurs at age-3 in both sexes. Growth rates for tautog from Virginia are similar to those reported nearly 25 years ago for tautog in Rhode Island. Growth rates for tautog are similar to those of other reef fishes, such as snappers and groupers. Habitat restriction, slow growth, great longevity, and increasing popularity by user groups may contribute to over-exploitation of this species in Virginia waters.

Develop A Chesapeake Bay-Wide Young-Of-The-Year Striped Bass Index : Final Report To The Chesapeake Bay Stock Assessment Committee (Cbsac), Herbert M. Austin, James A. Colvocoresses, Thomas C. Mosca
Reports
The objective of this study has been to develop a proportionally weighted Baywide young-of-the-year Chesapeake Bay striped bass index which incorporates data from all major nursery areas of the Chesapeake Bay. In doing so three approaches were used. The first entailed simple computation of both arithmetic and geometric indices. These were computed for historical continuity. The second approach involved a weighting by the commercial landings from each river during the spawning seasons from 1973-1981. The third approach used the area of the spawning grounds and distance of shoreline adjacent to the nursery grounds. Finally, an effort at validation was made …

Criteria For Predicting Zebra Mussel Invasions In The Mid-Atlantic Region, Patrick Baker, Shirley Baker, Roger Mann
Criteria For Predicting Zebra Mussel Invasions In The Mid-Atlantic Region, Patrick Baker, Shirley Baker, Roger Mann
Reports
What is the probability that zebra mussels will invade specific bodies of water within a given state? If they do invade, will they become economic and ecological pests as they have in portions of the Great Lakes? These and similar questions are addressed, with the expectation that management strategies can be developed to delay, mitigate, or possibly even prevent zebra mussel invasions, in some areas.
