This document reviews actions taken by intergovernmental organizations (IGOs), including regional fisheries management organizations (RFMOs) and other relevant regional fishery bodies (RFBs), to address problematic sea turtle and seabird interactions in marine capture fisheries. Sea turtles and seabirds are subject to a number of natural and anthropogenic mortality sources, including fishing operations. As a result, all sea turtle species of known status are recognized as being endangered. All sea turtle species excluding the flatback are listed in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which regulates international trade. Of the 61 species of seabirds affected by longline fisheries, 26 are threatened with extinction, including 19 species of albatrosses. The Convention on Migratory Species, which has a broader remit than CITES in terms of its requirements for both domestic and multilateral conservation measures, lists all sea turtles, albatrosses, giant petrels and Procellaria petrels in its Appendices. Due to concern over the status of sea turtles and certain species of seabirds and the possible negative effects of fishing on these populations, several IGOs have taken measures to address these problems. Some of these organizations have begun examining seabird or sea turtle interactions, several have adopted voluntary measures to address problematic interactions, while five RFMOs have legally binding measures requiring the employment of seabird avoidance methods in pelagic and demersal longline and trawl fisheries. There currently are no legally-binding measures in place by an IGO to manage turtle-fishery interactions or seabird interactions in coastal gillnet fisheries. Several IGOs, which lack fisheries management authority, serve as advisory mechanisms and conduct cooperative research, or have a primary responsibility of regional sea turtle or seabird conservation.
