Climate change and the management of high seas, straddling and migratory fish stocks

TL;DRAbstract

In this chapter, impacts of climate change on high seas, straddling and highly migratory stock fisheries are discussed in the context of capture fisheries trends and socio-economic implications. Factors considered include impact pathways, impact effects, future impacts and relationships to other trends. The exposure and sensitivity of fisheries to climate change are considered in terms of “vulnerability” and “resilience”. Climate change “adaptation” and “mitigation” are highlighted, noting a need to explicitly account for uncertainty in available climate impact information and potential fisheries responses. Gaps in current knowledge of climate change impacts are identified for high seas, straddling and highly migratory fish stocks. A need for relevant institutions to provide anticipatory adaptation measures to minimise impact(s) is recognised. Consequently, increased environmental and fisheries uncertainty have serious implications for the management of climate-impacted fisheries.
