Age Based Assessment In The Sea Scallop Placopecten Magellanicus: A Pilot Study - Final Report, Roger L. Mann, David Rudders, Sally Roman, Melissa Southworth, Kaitlyn R. Clark

Reports

If the current sea scallop fishery is well managed with a Catch At Size Analysis (CASA) length structured model, then why bother with an age based assessment? The success of the CASA based approach, in conjunction with management measures, is demonstrated by the development of the scallop fishery over the past two decades to its current status as the one of the most valuable fisheries on the Atlantic coast of the United States (NOAA, 2021). But, even the best length-based model can be improved by the addition of age data. An age-based model calibrates a length-based model, including a description …

Study Of Alosa Stock Composition And Year-Class Strength In Virginia - Annual Report 1985, Joseph G. Loesch, William H. Kriete Jr., Roxanne P. Trapani

Reports

This presentation is the annual report for P. L. 89-304, AFC 13-2 project "Study of Alosa stock composition and year-class strength in Virginia," for the period 15 February 1985 to 14 February 1986. The fishes of concern were the alewife (Alosa pseudoharengus), American shad (A. sapidissima), and the blueback herring (A. aestivalis).

Anadromous Fisheries Research Program, Virginia - Completion Report 1980-83, Joseph G. Loesch, William H. Kriete Jr.

Reports

This presentation 1.s the completion report for P. L. 89-304, AFC 10 project "Anadromous Fisheries Research, Virginia," for the period 1 October 1979 to 31 December 1983. 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 Alusa species 1.n Virginia were the lowest ever recorded. American shad and river herring are also sought by …

This presentation is the annual report for P. L. 89-304, AFC 13-1 project "Study of Alosa stock composition and year-class strength in Virginia," for the period 1 January 1984 to 31 December 1984. 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. Evaluation of the Alosa Stocks and Fisheries in Virginia
2. A Study of Juvenile Alosa Abundance Growth and Mortality

Transport Of Bivalve Larvae In The James River, Virginia, Jay D. Andrews

Reports

The James River is the primary source of seed oysters for planting private beds in the Chesapeake Bay. A sharp decline in setting rates after 1960 accompanied cessation of oyster culture on private beds in the lower sector of the river. These broodstocks were eliminated and the beds were barren after 1960. High salinities permitted a new oyster disease caused by Minchinia nelsoni (MSX) to make planting in the lower river hazardous because of high mortalities (Andrews, 1964 and in press).

Studies of larval transport mechanisms were begun in the James River in 1950, and extensive sampling was done from …

Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo

Reports

Contamination of the James River in Virgin ia with the pesticide Kepone has resulted in its accumulation in the tissues of the fauna inhabiting the river. Most of the Kepone available to the biota in the river is associated with sediment s (Schneider and Dawson, 1978) and Haven and Morales-Alamo (1979) have shown that oysters and other bivalve molluscs accumulate Kepone in their tissues when exposed to the pesticide associated with sediments in suspension. It is of interest to compare the quantities of Kepone bound in James River sediments with the quantities bound in the molluscan fauna of the river.
