Reports

This report presents information on catch of iuvenile fish with a 30 ft. semi-ballon trawl in the York and Rappahannock Rivers, and graphically compares those with the commercial landings in Virqinia waters for the years 1955 throuqh part of 1982 .

Anadromous Fisheries Research Program, Virginia - Annual Report 1982, Joseph G. Loesch, William H. Kriete Jr.

Reports

This presentation is the third annual report for P. L. 89-304, AFC 10 project "Anadromous Fisheries Research, Virginia," for the period 1 November 1981 to 31 October 1982. The fishes of concern were the alewife (Alosa pseudoharengus), American shad (A. sapidissima), and the blueback herring (A. aestivalis).

The Alosa species were once an important component of the landings of Virginia fisheries. In the last decade, however, there has been a dramatic decrease in American shad and river herring landings. The 1981 landings of Alosa species in Virgin.ia were the lowest ever recorded. American shad and river herring are also sought …

Development Of Oyster Resources, Katherine V. Leonard

Reports

During the 3-year project period, augmentation of cultch material and transplanting of seed oysters as a means of increasing oyster production was used. Sites were selected for the planting and transplanting. These sites were evaluated based on several criteria. One of the major considerations is the relative abundance of previous spatfall or production in a given area. Several additional factors reviewed for selection included approximate date of peak setting, substrate type (muddy, sandy, rocky, etc. bottom), impact of MSX, estimate of bar potential, gross fishing efforts and salinity regimes. It is important to plant a week or two prior to …
