Effects Of Oyster Population Restoration Strategies On Phytoplankton Biomass In Chesapeake Bay: A Flexible Modeling Approach, Rs Fulford, Dl Brietburg, Rie Newell, Wm Kemp, Mw Luckenbach

VIMS Articles

Cultural eutrophication in estuaries and other coastal systems has increased over the last 50 yr. Some recently proposed strategies to reverse this trend have included the restoration of bivalve suspension feeders as an ecological tool for reducing phytoplankton biomass. The ecological benefits accruing from such bivalve restoration will be dependent on the characteristics of the estuary, as well as how restoration is implemented. We developed a filtration model to estimate the effect of bivalve restoration on the rate of phytoplankton removal over a range of spatial and temporal scales and used it to compare alternate restoration strategies for the eastern …


Shark Bay Prawn And Scallop Fisheries. Draft Review Report, Department Of Fisheries Western Australia Apr 2007

Shark Bay Prawn And Scallop Fisheries. Draft Review Report, Department Of Fisheries Western Australia

Fisheries management papers

In recent times, the Department of Fisheries has received representations from both sectors about the ongoing interaction of the fisheries and their respective management settings. As a result, a decision was made to comprehensively review the fisheries, taking into account matters of fishery sustainability and gear interactions, together with industry economics and market considerations. The review has also addressed research requirements to ensure an appropriate scientific basis for decision-making into the future.


Plan Of Management For The Kalbarri Blue Holes Fish Habitat Protection Area, Department Of Fisheries Mar 2007

Plan Of Management For The Kalbarri Blue Holes Fish Habitat Protection Area, Department Of Fisheries

Fisheries management papers

The FHPA has been declared to protect and conserve an example of a near-shore reef community. In order to achieve this aim, and encourage the appreciation and conservation of fish, a number of management strategies have been identified which restrict recreational and commercial fishing. The FHPA is approximately 420 metres long and approximately 130 metres wide at the southern end and 140 metres wide at the northern end.


Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric T. Schultz, Jose J. Pereira, Peter J. Auster Jan 2007

Determining Winter Flounder Spawning Sites In Two Connecticut Estuaries, Eric T. Schultz, Jose J. Pereira, Peter J. Auster

EEB Articles

Winter flounder (Pseudopleuronectes americanus) come inshore during the late winter and early spring to lay their eggs in shallow bays and estuaries along the coast. Unlike most fish eggs, which are buoyant, these eggs are demersal and sink to the seafloor. This makes them vulnerable to burial from various types of natural and human caused disturbances (e.g., storms, mobile fishing gear, maintenance dredging). Our objective was to map spawning areas in two harbors and search for generalities among these sites that would allow us to predict where winter flounder might spawn in other areas. This would allow managers to avoid …


Habitat Preferences Of The Eastern Hellbender In West Virginia, S. Conor Keitzer Jan 2007

Habitat Preferences Of The Eastern Hellbender In West Virginia, S. Conor Keitzer

Theses, Dissertations and Capstones

The Eastern Hellbender, Cryptobranchus alleganiensis alleganiensis, is a species of concern in West Virginia and is in need of management. An important component of conservation efforts will involve identifying suitable habitat for protection. The goal of this research was to locate populations and examine hellbender habitat preferences to help managers identify habitat for protection. Populations were located using rock turning surveys from May through November, 2006. Hellbenders may be sensitive to water chemistry, so the dissolved oxygen, pH, turbidity, specific conductivity, and water temperature were measured. Substrate composition may influence populations, so substrate was characterized with Wolman pebble counts. …
