This guidance suggests actionable ways fisheries managers can utilize the types of survey and monitoring data generally being collected in priority areas (i.e. areas with distinctive biodiversity attributes or features) to measure biodiversity outcomes and meet requirements of other effective area-based conservation measures (OECMs) Criterion C. While there is no standard for documenting outcomes of areas reported to the Convention on Biological Diversity or World Database on Protected Areas, FAO recommends documenting all reported OECMs with enough information as possible. The hope is that this supplemental guidance will facilitate these processes and spur greater recognition of the role that effective fisheries management has in safeguarding ecological functioning and biodiversity.
