Paper briefly describes historical and emerging development activities in the Albemarle-Pamlico Sound area selected for study by a joint State/U. S. Environmental Protection Agency Task...
Economic Benefits to Chesapeake Bay Blue Crab Fishermen From Water Pollution Control and Habitat Restoration
Water pollution, primarily by herbicides and nutrients contained in agricultural runoff and in waste treatment plant effluent, appears to be a major cause of the decline in abundance of...
Community Based Marine Reserves, a Philippine First
This paper describes the Marine Conservation and Development Program (MCDP) of Silliman University, Dumaguete, Philippines. MCDP was a two-year project designed to enable three local communities...
Implementation of Habitat-based Evluations: Issues and Solutions
Since 1974, the US Fish and Wildlife Service has been developing a habitat-based evaluation methodology entitled Habitat Evaluation Procedures (HEP). The Los Angeles District's...
Fish Wintering in the Sagavanirktok Delta, Alaska
Anadromous fish of the Alaskan Beaufort Sea overwinter for eight to nine months in isolated pools of coastal rivers where water remains unfrozen through the winter. Available overwintering...
The Fish and Fisheries of the Amansuri Wetlands: A Coastal Blackwater System (
The Amansuri wetlands is a blackwater ecosystem situated on the southwestern coast of Ghana. It covers an area of 75 Km 2 which can be divided by vegetation into four ecological zones....
Marine Protected Areas and Customary Rights
Customary rights and their importance to the establishment and management of coastal and protected marine areas has emerged as an issue of universal concern. Local involvement in the planning...
Oil Rigs: Biology, Mariculture, Drilling Muds, Rigs-to-Reefs
Oil platforms in the Gulf of Mexico and Santa Barbara Channel provide hard substrates, diverse habitats and excellent breeding grounds from the sea floor through the splash zone. As a...
North Fraser Harbour Environmental Management Plan
In April 1985, the North Fraser Harbour Commission (NFHC) initiated work to establish an environmental management program for the North Fraser Harbour to be jointly administered by the...
Aquatic Dredged Material Disposal in New England
The Disposal Area Monitoring System (DAMOS) is a large multi-disciplinary environmental monitoring program instituted by the New England Division (NED) of the U. S. Army Corps of Engineers...
Loss of Aquatic Habitat in Quincy Bay
Quincy Bay is a backwater area along the upper Mississippi River near Quincy, Illinois. The construction in 1969 of a small boat access channel about 3. 2 km upstream of the natural bay...
Versatile Methodology for Flow Depth and Velocity Modeling in Stream Aquatic Habitat Assessment
The habitat assessment methodology developed by the IFG Instream Flow Group is a useful tool for evaluating instream flow needs. The methodology for basin flow modeling developed in this...
Reservoir Water Quality Assessment Using in Situ Microcosms
Although there are a number of techniques for determining the limiting nutrient, as will be demonstrated, in-reservoir microcosms permit in situ experiments to be conducted under relatively...
Water Use by Saltcedar in an Arid Environment
Specialized instruments and measurement techniques developed at the University of Arizona facilitate precise estimation of evapotranspiration (ET) with the energy budget model. Use of...
Management Strategy
Meanders of sinuous streams are often cut off by natural action or by man in order to improve conveyance or navigability. Cutoff bendways, as long as they remain aquatic, provide extremely...
A Model Relating Water and Sediment Yield to Upstream Agricultural Practices
A physical-process model is formulated to quantify daily water and sediment yield as related to upstream land use, land management, and soil and water conservation measures. This model...
Comparison of Minimum Instream Flow Needs
A sound determination of Instream Flow requirements is facilitated by the use of a physical habitat versus streamflow relationship and the analysis of instream flow benefits produced when...
Instream Flow Needs to Protect Fishery Resources
Numerous methods have been developed over the past several decades to assess the effects of flow regulation on fishery resources and to provide a basis for the determination of suitable...
Benefit-Cost Evaluation of Minimum Instream Flows
In many cases, determinations of minimum desirable instream flows (MIF) are made without full consideration of economic costs and benefits. Benefits are frequently quantified in nonmonetary...
