Compared to Figure 1 a relatively stable population of large zooplankton was achieved by using the displacement volume to adjust grain feeding rate and control grazing on zooplankton by carp. U.S. AQUACULTURE SOCIETY Sponsored Publications Request for Proposals The USAS is seeking proposals for publications, including books, conference proceedings, fact sheets, pictorials, hatchery or production manuals, data compilations, and other materials that are important to U.S. aquaculture development and that will be of benefit to USAS members. Individuals wishing to have a project considered for funding by the USAS should prepare a proposal — guidelines are available on the website www.was.org. Conditions for Publication: The USAS Board of Directors will rate proposals and select projects for publication. The successful applicant will serve as co-author; however, depending on contribution to the publication, the applicant may not necessarily serve as chief or sole author. The USAS will cover general publication and distribution costs for one or more projects up to $5,000 each year. However, special consideration will be given to worthwhile projects that exceed this limit. No compensation will be provided to the authors for their time spent in writing the publication. The publication will be property of the USAS and will be sold through the WAS bookstore. See details on submitting a proposal on the next page or contact: DR. LUKE A. ROY Phone: 501-676-3124 • Email: lroy@uaex.edu results in a sustainable population of large cladocerans throughout the growing season (Fig. 5). Thus, carp could feed on a diet consisting of natural zooplankton and cereals. This strategy helped to save feed (up to 764 kg/ha) without reducing carp yield (up to 722 kg/ha) and as a result saved money (Schlott et al. 2011).
