Reports
This report presents the results of striped bass (Marone saxatilis) tagging and monitoring activities in Virginia during the period 1 September 2004 through 31 August 2005. It includes an assessment of the biological characteristics of striped bass taken from the 2005 spring spawning run, estimates of annual survival based on annual spring tagging, and the results of the fall 2004 directed mortality study that is a collaborative effort with the Maryland Department of Natural Resources. The information contained in this report is required by the Atlantic States Marine Fisheries Commission and is used to implement a coordinated management plan for …

A principal requirement of multispecies fisheries assessment models is well-quantified estimates of predator-prey relationships (Latour et al. 2003). Trophic interactions among populations are typically elucidated through the analysis of stomach contents. It must be recognized, however, that such interactions vary according to temporal and spatial scales. Therefore, to adequately characterize these interactions within an ecosystem, an extensive database of fish diet composition information is needed. Further, given that increased survival in the early life history stages may ultimately improve the year-class strength of a fish population (Boynton et al., 1981 ), consideration of young-of-the year (YOY) and juvenile fish diets …
Monitoring Relative Abundance Of American Shad In Virginia Rivers 2004 Annual Report, John E. Olney
Monitoring Relative Abundance Of American Shad In Virginia Rivers 2004 Annual Report, John E. Olney
Reports
Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …
National Coastal Assessment Program Assessing Virginia’S Estuaries And Tidal Tributaries To Chesapeake Bay And The Atlantic Ocean (Five Year Report 2000 - 2004), Marcel M. Montane, Wendy A. Lowry

The Virginia Institute of Marine Science (VIMS) was contracted by the Virginia Department of Environmental Quality (DEQ) to participate in the Environmental Protection Agency’s (EPA) National Coastal Assessment (NCA) by collecting fish at pre-determined stations and obtaining information on community structure of fish and invertebrates and bottom habitat. Over each of the first five years of NCA, samples of fish (five chosen target species) have been collected for delivery to DEQ for subsequent tissue analysis. A five-year SAS dataset containing all pertinent information has been produced. This report summarizes Virginia NCA field studies from 2000 through 2004.

Estimation Of Juvenile Striped Bass Relative Abundance In The Virginia Portion Of Chesapeake Bay, January 2004-December 2004 : Annual Progress Report, Herbert M. Austin, Amanda H. Hewitt, Julia K. Ellis
Reports
The primary objective of the Virginia Institute of Marine Science juvenile striped bass survey is to monitor the relative annual recruitment success of juvenile striped bass in the major Virginia nursery areas of lower Chesapeake Bay. The U.S. Fish and Wildlife Service initially funded the survey from 1967 to 1973. After a hiatus ending in 1980, funds were provided by the National Marine Fisheries Service under the Emergency Striped Bass Study program. Commencing with the 1988 annual survey, the work was jointly supported by Wallop-Breaux funds (Sport Fish Restoration Act) administered through the U.S. Fish and Wildlife Service and the …
