Oyster Spatfall On Shellstrings In Virginia Rivers: 1976 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

The Virginia Institute of M3rine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur, Shells planted just before the period of maximum set have the best chance of getting a good strike,

Oyster Spatfall On Shellstrings In Virginia Rivers: 1974 Annual Summary, Dexter S. Haven, Paul C. Kendall Jan 1975

Oyster Spatfall On Shellstrings In Virginia Rivers: 1974 Annual Summary, Dexter S. Haven, Paul C. Kendall

Reports

Oyster setting levels in m9st Virginia river systems are still far below those which commonly occurred prior to 1960. However, the 1974 season showed continuing improvement since 1972 when Tropical Storm Agnes raged through the Chesapeake Bay region, creating adverse environmental conditions which were largely responsible for the lowest setting levels on record. Data for 1973, as well as for 1971 and 1972 are included in this summary for comparison with the 1974 setting season. Setting information is obtained through surveys conducted weekly by the Virginia Institute of Marine Science (VIMS) from June through early October, with assistance of personnel …

Oyster Spatfall On Shellstrings In Virginia Rivers: 1972 Annual Summary, Virginia Institute Of Marine Science Jan 1973

Oyster Spatfall On Shellstrings In Virginia Rivers: 1972 Annual Summary, Virginia Institute Of Marine Science

Reports

Oyster setting in Virginia river systems dipped to the lowest levels on record during 1972, according to scientists at the Virginia Institute of Marine Science who regularly monitor oyster grounds for set. A heavy set occurred on the seaside of Virginia's Eastern Shore and limited setting was observed in tributary rivers of the Mobjack Bay, but elsewhere the number of oysters setting on shellstrings and on the bottom in lower Chesapeake Bay in 1972 was far lower than for the previous year, and the lowest overall set ever recorded.


Oyster Spatfall On Shellstrings In Virginia Rivers: 1970 Annual Summary, Dexter S. Haven Nov 1970

Oyster Spatfall On Shellstrings In Virginia Rivers: 1970 Annual Summary, Dexter S. Haven

Reports

The Applied Biology Department in the VIMS Division of Applied Marine Science and Ocean Engineering conducts. weekly surveys of oyster "setting" in Virginia rivers from the end of May through early October each year. Starting at the mouth of each river and proceeding upstream to the limits of oyster setting, the collecting areas a.re established on public and private beds. Spat counts are obtained from oyster shells strung on wire and suspended from stakes. The number of spat which set in one week on the smooth side of ea.ch shell on the string are tabulated.
