Abstract Bivalve aquaculture is an expanding industry and there is a strong need for the identification of ecologically and socially feasible levels of aquaculture production in order to promote sustainable growth. In this context, the concept of carrying capacity serves to determine acceptable limits for aquaculture expansion. This study compares three case studies from different parts of the world where bivalve aquaculture represents an important socio-economic activity. Through a media analysis, public perception of aquaculture is analyzed and critical aspects shaping the process of societal discussion in the different settings are discussed. Public perception of aquaculture-related activities was mainly positive for all three case studies, and local socio-economic characteristics were found to likely to drive the process of social carrying capacity estimation. This work aims to provide a basis for the advancement of the definition of sustainable practices required for an Ecosystem Approach to Aquaculture. Understanding local socio-economic settings and public perceptions on aquaculture is assumed an important first step towards accessing the social dimension of carrying capacity.
