From Principle to Practice: A Pragmatic Pathway for Ecosystem-Based Fisheries Management in a Data-limited RFMO

Abstract

The Southern Indian Ocean Fisheries Agreement (SIOFA) is legally mandated through its founding agreement to implement an Ecosystem Approach to Fisheries Management (EAFM). However, like many Regional Fisheries Management Organizations (RFMOs), translating this principle into effective practice poses significant challenges, particularly in data-limited environments. This viewpoint paper traces SIOFA’s pragmatic journey in operationalizing EAFM. We detail the organization’s early adaptive strategies, which included precautionary alignment with other RFMOs for managing seabirds and Vulnerable Marine Ecosystems (VMEs), and evidence-based conservation measures for deepwater sharks driven by targeted ecological risk assessments. While effective, these approaches highlighted a fundamental barrier: the Scientific Committee’s limited access to integrated fisheries data. In response, SIOFA developed an internal synthesis tool—the SIOFA Ecosystem Summary, to synthesize and streamline data access, thereby directly supporting science-based advice. This perspective paper argues that SIOFA’s experience demonstrates a pragmatic, phased pathway for EAFM implementation that reflects broader trends among RFMOs. While similar ecosystem synthesis tools exist in other bodies (e.g., NAFO, ICES, IOTC), SIOFA’s process is distinctive in its iterative co-development between the Secretariat and Scientific Committee within a resource-constrained setting. This paper contends that such adaptive, context-sensitive approaches offer practical insights for data-limited RFMOs seeking to operationalize EAFM.
