Anadromous Fisheries Research Program, Virginia - Annual Report 1980, Joseph G. Loesch, William H. Kriete Jr.

Reports

This presentation is the first annual report for P. L. 89-304, AFC 10 project "Anadromous Fisheries Research, Virginia," for the period 1 October, 1979 to 30 September 1980. 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?
