Roadmap to recovery: a global network of marine reserves

The high seas lie beyond the 200 nautical mile limits that define the extent of national sovereignty by countries of the world. They cover 64% of the area of the oceans, and nearly half the surface of the planet. They are a global commons, under the stewardship of the United Nations Law of the Sea for the benefit of all nations. But human pressures on the high seas are increasing fast, and urgent action is needed to protect them from harm. Recent research shows that industrial fishing has

Marine reserves in New Caledonia: case study

New Caledonia is surrounded by a large and rich lagoon which is enclosed by a barrier reef over 1,000 km long. Exploitation of the living lagoon resources to meet local requirements for
fish and other seafood has not, up to now, greatly affected the overall bio-ecological balance of the lagoon environment because New Caledonia's population density is very low.
The sea area near the capital of Noumea, where over half of the

Secluded from human interaction, the pristine Duff Reef or Cakau Galu in Mavana, Vanuabalavu in Lau has become a turtle sanctuary in Fiji. With its stunning natural aspects, the reef has now become a marine reserve – a protected home for turtles.

Researchers have found “sea rainforests” in deep seas, most of them in the two-thirds of the ocean’s deep waters where no nation has jurisdiction. The 116 coral reefs live mostly between 200m and 1,200m in-depth, with some of them at 2 km underwater.

A connectivity portfolio effect stabilizes marine reserve performance

Well-managed and enforced no-take marine reserves generate important larval subsidies to neighboring habitats and thereby contribute to the long-term sustainability of fisheries. However, larval dispersal patterns are variable, which leads to temporal fluctuations in the contribution of a single reserve to the replenishment of local populations. Identifying management strategies that mitigate the uncertainty in larval supply will help ensure the stability of recruitment dynamics and minimize the volatility in fishery catches.
