Children are often marginalized in research on local perceptions and values of the environment, and even more of marine spaces and species. Yet, as users and future managers of fisheries, they are directly concerned by issues related to their sustainability. Moreover, they not only receive, but also contribute to produce, hybridize, and circulate fisheries-related knowledge. As shown in several recent research projects and the growing scientific literature on the matter, drawings allow children to express their relationships with their environment in a playful and age-appropriate way, and are therefore a particularly relevant tool for exploring children's ecological knowledge. As part of the research project A Sea of Connections: Contextualizing Fisheries in the South Pacific Region (SOCPacific, 2018-2022), we have designed a transdisciplinary protocol based on drawings made by children in order to provide innovative insights into the social values of fisheries-related places and resources.
