Book Description
"This publication is one in a series of reviews of the use of the dredged material containment areas for aquaculture. This handbook is a useful overview of a demonstration project's results; site selection, design and construction; project planning and design; economics and business planning; and legal considerations. It will be of interest to aquaculturists, landowners, coastal zone planners, and other potential users of the containment area aquaculture concept"--National Sea Grant Library publication website.

Book Description
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 ...

Book Description
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.

Book Description
"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.
