Available in PDF, EPUB and Kindle. Book excerpt: The view that active dredged material containment areas (DMCA) are unproductive, commercially unusable, and incompatible with local needs can be challenged by demonstrating that there are situations where dredged material and DMCA's can be used to create positive benefits. One example would be a profitable and biologically productive use of disposal acreage for aquaculture. A 2 day workshop on aquaculture in DMCA's held in Galveston, Tex., in September 1982 attended by representatives from the Corps, other Federal and State agencies, private industry, and academia, examined issues affecting the technical, economic, and practical use of DMCA's for aquaculture ...

Available in PDF, EPUB and Kindle. Book excerpt: "The U.S. Army Corps of Engineers maintains more than 400 ports and more than 25,000 miles of coastal and inland waterways. Many harbors and navigation channels silt up and require maintenance dredging to be kept open. Estimates of the amount of sediment dredged by the Corps of Engineers range from 300-400 million cubic yards annually. Disposal in dredged material containment areas (DMCAs) suits the needs of many dredging projects. On the national level, an estimated 7,000 acres of new DMCAs are needed annually. In many parts of the country, finding and acquiring suitable sites is difficult. Research by the Corps of Engineers identified aquaculture as a potential beneficial use of containment areas. By designing and operating a DMCA for both material placement and aquaculture, benefits could be realized by the landowner, the aquaculture industry, local port and waterway authorities, and the Corps of Engineers. The focus of this report is an introduction to aquacultural economics as it pertains to dredged material containment areas"--National Sea Grant Library publication website

This book was released on 1992 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Since the enactment of the National Environmental Policy Act (NEPA) in 1969, there has been increased reliance on confined or on-land facilities for disposal of dredged material. Acquisition, however, is increasingly difficult because of high real estate values, the long-term nature of the easements, and the perception by landowners that dredged material is not aesthetic. The U.S. Corps of Engineers has worked to identify ways in which the landowner can use the acreage for activities that are financially attractive but do not interfere with periodic disposal of dredged material. One of these activities is aquaculture. This report summarizes information on legal and institutional constraints on aquaculture in DMCA. Laws, regulations, and permit requirements that may apply to DMCA aquaculture are outlined; potential legal difficulties are identified and methods of avoiding them are suggested"--National Sea Grant Library publication website
Download or read book Guide to Site Selection Design and Construction of Dredged Material Containment Areas for Aquaculture written by Debbie Nettles and published by . This book was released on 1992 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Approximately 40 percent of dredged material generated from coastal dredging activities is placed into diked dredged material containment areas or DMCA. Because suitable sites are often difficult and expensive to acquire, the U.S. Army Corps of Engineers and local dredging sponsors have an ongoing interest in programs that may help in making real estate available for DMCA construction. The adaptation of diked disposal areas for aquaculture is especially interesting because DMCA's and aquaculture ponds share many characteristics​, including perimeter dikes, structures to regulate water levels, construction on impervious soils, and many similar permit requirements. This publication provides guidelines for evaluating and selecting sites and for designing and constructing sites for the uses of dredged material disposal and aquaculture. Also included are examples of potential species for new operations"--National Sea Grant Library publication website.

Book excerpt: This report is inteded to provide an overview of the considerable knowledge and experience that has been developed worldwide in the design, construction, and operations planning of pond-based aquaculture systems Because this is a complex subject and requirements for specific situations are highly variable, only generalized, conservative views will be presented. The review is not intended for experts or those experienced in aquaculture pond design and construction. it is intended primarily as an information resource for those involved in aquaculture development.

This book was released on 1983 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses results of three laboratory studies where invertebrate animals were exposed to contaminated sediments for periods of 30 to 136 days. Sediments and animals were analyzed for metals and PCB, but not for pesticides or petroleum hydrocarbons. Lead was the only metal which showed a slight potential for transfer from sediment to organism. The data did indicate, however, that PCB in sediment is available. Bioaccumulation of PCB was affected by level of sediment contamination, characteristics of the sediment such as particle size and organic content, and life-style of the organism. Data on sediment and a clam species from a containment area near Port Arthur, Texas, are also presented. The analyses indicated only low levels of contaminants with levels in Rangia generally lower than sediment levels. These data are discussed in relation to use of containment areas of producing edible fish and shellfish or bait species. Excess animals could be used to supplement existing fish or shellfish in nearby lakes or estuaries.

Available in PDF, EPUB and Kindle. Book excerpt: "The lack of suitable sites often creates a problem for the coastal aquaculturist. One solution is to build ponds that can be used in the aquaculture operation for raising fish or other species and can also be used by the U.S. Army Corp of Engineers for placing material dredged from waterways. This publication gives a clear outline of issues to consider before jumping into the aquaculture business in general and the construction of ponds for dredged material containment and aquaculture in particular. This guide dispels some aquaculture myths, details investment and operating costs to expect, gives an overview of pond design and construction, provides a brief look at requirements of various species and provides a checklist to help in the decision about establishing an aquaculture operation"--National Sea Grant Library publication website

This book was released on 1993 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: High land and construction costs hinder development of pond-based aquaculture in the United States. A partnership with the U.S. Army Corps of Engineers (USACE) may reduce these constraints. The dredged material containment areas (DMCA) operated by the USACE are structurally similar to aquaculture ponds and typically are used by the USACE only once every 3 to 10 years. With the Corps and navigational interests contributing to dike construction and land acquisition, the costs of aquaculture may be reduced while providing the Corps with the additional disposal areas needed to maintain our nation's waterways. The Containment Area Aquaculture Program (CAAP) was established to investigate the feasibility of DMCA aquaculture from biological, economic, engineering, and legal perspectives. The technical feasibility of DMCA's was demonstrated in 42- and 47-ha DMCA's near Brownsville, TX. Pumps, filters, and drainage structures were added to these DMCA's to accommodate aquaculture operations and a 1.6-ha nursery pond was constructed. During a 3-year period, four crops of penaeid shrimp were raised. Production rates averaged 670 kg/ha of whole shrimp (range: 338 to 1,143 kg/ha) with 51 percent survival (range: 23 percent to 74 percent). Total production for the four crops was 116,088 kg of whole shrimp (71,878 k tails), and this was sold for over $475,000.
