Anadromous Fisheries Research Program, Virginia - Annual Report 1981, Joseph G. Loesch, William H. Kriete Jr.

Reports

This presentation is the annual report for P. L. 89-304, AFC 20 project "Anadromous Fisheries Research, Virginia," for the period 1 December, 1980 to 30 November 1981. The fishes of concern were the alewife (Alosa pseudoharengus), American shad (A.sapidissima), and the blueback herring (A.aestivalis).

The following jobs were performed:

1. Catch and Effort Statistics of the Virginia Anadromous Fisheries
2. Population Dynamics of the Virginia Alosa Fisheries
3. Annual Index of Juvenile Alosa Abundance

Determination Of The Presence, Species Composition, And Relative Abundance Of Anadromous Fishes In Pohick Creek, Fairfax, Virginia, Joseph G. Loesch

Reports

The overall concern of the study was to determine if fish laddero are needed to permit upstream migration of spawning anadromous fishes beyond the sites of impoundment. Specific questions addressed were:

1. Do anadromous species presently utilize Pohick Creek?

2. If so, what species are present?

3. How far do the species migrate upstream?

4. What is the relative abundance of the species?

5. Wl1at effects will impoundments, with ~nd without fish ladders, have on the anadromous fish resource?

Summary Of Sea Turtle Research In Virginia During 1979 And 1980: Final Report For Nmfs Contract #80 Fac 00004, John A. Musick

Reports

Directed research on the status of sea turtles in Virginia has been carried out by VIMS personnel since May 1979. Our efforts in 1979 (supported in-house) primarily comprised a documentation of sea turtle mortalities in the state. This. work was expanded somewhat in 1980 thru a small Fellowship Stipend from N.M.F.S, to support the thesis work of Molly Lutcavage. In 1980 Molly analyzed the 1979 mortality data, continued to monitor strandings, and began a tagging program in cooperation with selected poundnet fishermen. Also in 1980 we began an evaluation of sea turtle nesting in Virginia with the support of another …

Reports

In May of 1980, we initiated a project to evaluate the nesting use of Virginia's Atlantic coastal beaches by the loggerhead sea turtle, Carretta caretta.

l'he loggerhead is considered an endangered species by the Commonwealth of Virginia and the species is on the federal threatened list.

Continuous Plankton Records : Zooplankton And Net Phytoplankton In The Southern Regions Of The Middle Atlantic Bight, 1978-80, Cathy E. Meyer, Herbert Austin

Reports

The Virginia Institute of Marine Science (VIMS) is currently providing logistical and scientific support to the Atlantic Environmental Group's Ship of Opportunity program in accordance with a VIMS/NOAA service contract. This program includes a Continuous Plankton Recorder - Expendable Bathythermograph (CPR/XBT) survey along a standard transect off the Chesapeake .Bay. Analysis of biological and physical data for this particular route is being processed by VIMS according to the standardized procedure set forth by NOAA and the Institute for Marine Environmental Research (IMER) of the United Kingdom.
