World Aquaculture Magazine -December 2021

WWW.WA S .ORG • WORLD AQUACULTURE • DECEMBER 2021 15 I n each issue of World Aquaculture , we highlight exciting papers from the Journal of the World Aquaculture Society. In this issue we highlight a recent Special Issue and the following paper “Evaluation of nutrient bioextraction by seaweed and shellfish aquaculture in Korea” by J.-S. Park, S.K. Shin, H. Wu, C. Yarish, H.I. Yoo and J.K. Kim. The article appears in the Journal of the World Aquaculture Society, volume 52, issue 5, pages 1118-1134. It is available at: https://doi.org/10.1111/jwas.12786 or under the Publications tab at the WAS website ( www.was.org) . Macroalgae and bivalve aquaculture may offer nutrient sinks at scales that are of national, international or even global significance. Comparing extraction by these species to known human emissions can make the utility and importance of extractive species aquaculture more apparent. Park et al. offer a comprehensive analysis of Korean Recent Research Highlight from the Journal of the World Aquaculture Society aquaculture production and show that 161,846 tons of CO 2 and 7,251 tons of Nwere removed by three major seaweed species and two shellfish species. This level of removal is equivalent to 5.7 percent of the CO 2 and 8.6 percent of N discharged from all wastewater treatment plants in Korea. Not only is this form of bioextraction highly effective, it is economically viable and equitable. This paper is part of the recent special issue “Seaweed Aquaculture – FromHistoric Trends to Current Innovation” guest edited by Jang K. Kim, Simona Augyte and Charles Yarish. This exceptional compilation of eight applied studies and a review offers insights into culture techniques, impacts of climate change on future production, and important training and outreach programmes on seaweed culture.
