Sustainable management of the high seas could recoup fish stock losses due to climate change

Closing the high seas to fishing could increase fish catches in coastal waters by 10%, compensating for expected losses due to climate change, finds a new Nippon Foundation-Nereus Program study published in Fish and Fisheries.

The high seas are those areas of the ocean outside the jurisdiction of countries; the high seas cover nearly two thirds of the ocean’s surface. These results could be seen by 2050 relative to 2000 and cooperatively managing the high seas fisheries would have similar effects.

Instability in the South China Sea: Ecosystem challenges and political complexities

One of the most significant – and increasingly bitter – international disputes of recent years has engaged legal claims over maritime territory in the South China Sea. Under the United Nations Convention on the Law of the Sea of 1982 (UNCLOS), to which the main protagonists are parties, states are entitled to claim an Exclusive Economic Zone (EEZ) conferring sovereign rights and jurisdiction up to 200 nautical miles of maritime space from their coasts. In the South China Sea, however, this position has been complicated by historical claims over a series of small islands and reefs within the southern section of this area.

The role of transnational corporations in global fishery reform

It’s important to address the activities of transnational corporations in global fishery reform, argues a new letter co-authored by Nereus Program Principal Investigator Henrik Österblom, Stockholm Resilience Centre, and published in PNAS.

The paper is a commentary on “Global fishery prospects under contrasting management regimes” by Costello et al., which found that sound management reforms could increase annual catch by 16 million metric tons, at $53 billion in profit. The authors highlighted ten countries that “provide the most compelling and urgent case for fishery reform” — China, Indonesia, India, Japan, Philippines, Thailand, Malaysia, Republic of Korea, Vietnam, and Taiwan.

Temperature-based targeting in a multispecies fishery under climate change

The paper “Temperature-based targeting in a multispecies fishery under climate change” was recently published in Fisheries Oceanography by Nereus Program Fellow Daniel Dunn (Duke University) and Principal Investigator Patrick Halpin (Duke University). The study looked at whether the bottom temperature of the water, in spring and fall, affected the distribution of Atlantic cod in the USA Northeast compared to other species of fish.

Ask an Expert: Why is the global fishing industry given $35 billion in subsidies each year?

OceanCanada Research Director Rashid Sumaila and his collaborators from the UBC Global Fisheries Cluster (Sea Around Us and the Nereus Program) have published an updated estimate of global fisheries subsidies in the international journal Marine Policy. The researchers found that the global fishing industry is being supported by $35 billion yearly in government subsidies, the majority of these, upwards of $20 billion annually, promote increased capacity that can lead to harmful impacts such as overfishing.
