World Aquaculture December 2019

12 DECEMBER 2019 • WORLD AQUACULTURE • WWW.WA S.ORG I n each issue of World Aquaculture , we highlight a new and exciting research paper from the Journal of the World Aquaculture Society. This issue’s selected paper is drawn from the most recent special issue of JWAS on Functional Aquafeeds and is entitled “Feed preference and growth response of juvenile Litopenaeus vannamei to supple- mentation of marine chemoat- tractants in a fishmeal-challenged diet” by Alberto J. P. Nunes, Hassan Sabry-Neto, Severino Oliveira-Neto and Lena Burri. Diets for whiteleg shrimp Litopenaeus vannamei require increasing levels of fishmeal replacement. Replacement of marine protein generally increases sustainability of Recent Research Highlight from the Journal of the World Aquaculture Society diets and reduces overall cost but can mean diets contain antinutritional factors that reduce initial feeding, feeding continuation and overall growth performance. Highly effective chemoattractants are often essential to maintaining palatability in diets formulated with high levels of alternative proteins and lipids. Feed intake and resulting growth performance can be significantly improved if the right (marine) attractant is applied. The authors formulated shrimp diets with near-complete replacement of marine proteins and then applied a wide pallete of potential chemoattractants: U.S. AQUACULTURE SOCIETY Sponsored Publ icat ions Reques t for Proposal s 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. • CONTACT: Dr. Ken Cain • PHONE: 208-885-7608 • EMAIL: kcain@uidaho.edu ( C O N T I N U E D , B O T T OM P A G E 1 3 )
