A Scoping Review: Operationalization of Resilience Principles to Address Stressors in Oyster Aquaculture

Oyster aquaculture plays a critical role in coastal social-ecological systems by providing ecosystem services such as economic benefits, food security, and environmental regulation; however, multiple biophysical and socio-economic stressors threaten its long-term sustainability. This study operationalizes the seven established resilience principles to identify strategies that enhance the resilience of oyster aquaculture globally. A scoping review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted across Scopus, Web of Science, and JSTOR, yielding 345 peer-reviewed publications (2000–2026) from which 13 stressor categories and 15 mitigation strategy categories were identified. Diseases and pathogens constituted the most documented stressor (24.3%), followed by climate change and ocean acidification (9.9%). Among strategies, the governance, policy, and stakeholder engagement strategy was the most frequently used (12.8%). Classification by resilience principles revealed that managing slow variables and feedback (P3, 30.1%) and maintaining diversity and redundancy (P1, 22.6%) dominated the literature, while broadening participation (P6, 11.0%) and promoting polycentric governance (P7, 4.6%) were least represented, revealing a significant gap in the scientific literature between biophysical and socio-institutional research attention. Context-specific indicators were developed for each principle, providing a replicable framework linking stressors, strategies, and resilience principles applicable to diverse mariculture systems.
