Aldridge Department of Zoology, The David Attenborough Building, University of Cambridge, Pembroke Street, Cambridge, CB2 3QY, United Kingdom ARTICLE INFO ABSTRACT Keywords: There is a global need to sustainably increase aquaculture production to meet the needs of a growing population. Microencapsulated diet Bivalve shellfish aquaculture is highly attractive from a human nutrition, economic, environmental and eco- Bivalve shellfish system standpoint. However, bivalve industry growth is falling behind fish aquaculture due to critical problems Food security in the production process. Feed defects, disease, and quality issues are limiting production. New advances in Aquaculture microencapsulation technology have great potential to tackle these problems. Microencapsulated diets could Sustainable efficiently deliver high-quality nutrients, disease control agents, and quality enhancers to bivalves. Microencapsulation has the potential to drive improvements in bivalve production, reduce production costs, enhance human nutrition and minimise impacts on the environment. 1. The global importance of bivalve shellfish aquaculture fastest growing food sector (FAO, 2017; Jacquet et al., 2017; Tacon and Metian, 2013; Troell et al., 2014). However, like terrestrial meat pro- 1.1. Bivalves a strategic food source to sustainably feed a growing global duction aquaculture is currently expanding in an unsustainable way population (Godfray et al., 2010; Jacquet et al., 2017). Production quantity of carnivorous species such as salmon, catfish, and shrimp has ballooned, Over 800 million people worldwide are hungry, one billion have growing 84% over the last decade, and today salmon is the largest inadequate protein intake, and an even greater number suffer from single commodity in aquaculture (FAO, 2017, 2016).
