Water Quality Conditions And Restoration Of Submerged Aquatic Vegetation (Sav) In The Tidal Freshwater James River 2005, Ken Moore, Betty Neikirk, Britt-Anne Anderson
Water Quality Conditions And Restoration Of Submerged Aquatic Vegetation (Sav) In The Tidal Freshwater James River 2005, Ken Moore, Betty Neikirk, Britt-Anne Anderson
Reports
In 2005, wild celery (Vallisneria americana) whole shoots, seeds and intact seed pods with seeds were transplanted into four sites in the Hopewell region of the tidal James River. The SAV transplants were sampled by the Virginia Institute of Marine Science (VIMS) for survivorship and growth at bi-weekly to monthly intervals throughout the growing season. Concurrently, water quality sampling was conducted at bi-weekly intervals throughout the year for water column nutrients, chlorophyll a, suspended solids, water transparency and other chemical and physical constituents important for SAV growth. Continuous underway sampling was also conducted along the James River tidal freshwater segments …
Effectiveness Of The Blue Crab Spawning Sanctuary In Chesapeake Bay, Debra M. Lambert, Rom Lipcius, John M. Hoenig
Effectiveness Of The Blue Crab Spawning Sanctuary In Chesapeake Bay, Debra M. Lambert, Rom Lipcius, John M. Hoenig
Reports
The blue crab spawning stock in Chesapeake Bay sustained a severe and persistent decline beginning in 1992. As part of the effort to enhance the spawning stock, the spawning sanctuary in lower Chesapeake Bay was enlarged to over 240,000 ha. This marine reserve and corridor prohibits exploitation of mature females en route to or in the spawning grounds during the summer spawning season (1 June-15 September). To assess the effectiveness of the sanctuary, we tagged terminally molted, mature females inside and outside the sanctuary during three sanctuary seasons (2002-2004). Crabs were captured throughout the Bay and its tributaries, measured, tagged, …
Abundance, Biomass And Size Structure Of Eastern Oyster And Hooked Mussel On A Modular Artificial Reef In The Rappahannock River, Chesapeake Bay, Rom Lipcius, Russell P. Burke
Abundance, Biomass And Size Structure Of Eastern Oyster And Hooked Mussel On A Modular Artificial Reef In The Rappahannock River, Chesapeake Bay, Rom Lipcius, Russell P. Burke
Reports
Restoration efforts with native Eastern oyster, Crassostrea virginica, in Chesapeake Bay have been extensive, and there has been a continuing search for reef structures that will be effective under a range of environmental conditions. We quantified population structure, density, abundance and biomass of Eastern oyster and hooked mussel, Ischadium recurvum, on a novel concrete modular reef deployed subtidally (~ 7 m depth) in the lower Rappahannock River during October, 2000. The reef provided 3-D architectural complexity, substrate stability, and extensive surface settlement area (nearly 75 m2 of reef surface over 5 m2 of river bottom). Upon deployment, the reef was …
