In theory, no-take marine reserves hold benefits for nearby fisheries: the reserves allow target species to grow older and larger, produce more young, and ultimately replenish fished areas with larvae and/or adults. While evidence of benefits to fisheries has appeared in scientific literature, some researchers argue that most science on reserves has not involved sufficiently rigorous experimental design, including the use of control sites.

In a move to protect the waters of one of the most remote places on Earth, Australia has designated a giant marine reserve around an island group just outside the Antarctic Circle. At 65,000 km2, the Heard Island and McDonald Islands Marine Reserve is the world's largest no-take area - roughly the size of Belgium, the Netherlands, and Luxembourg combined.

Representative networks of marine protected areas should be established worldwide by the year 2012, and depleted fish stocks restored by 2015, according to an action plan agreed upon by global leaders at the World Summit on Sustainable Development (WSSD), held earlier this month in Johannesburg, South Africa. The agreement also calls on governments to incorporate an ecosystem approach in fisheries management by 2010, eliminate subsidies that contribute to fishing-industry over-capacity, and protect marine biodiversity on the high seas.

Think of a community-based MPA and you might well imagine a rural coastal village managing its ocean resources with little, if any, outside involvement. In Fiji, however, a unique mix of geographic, environmental, and political conditions has helped foster a partnership for the protection of small community-based MPAs, uniting the interests of community members and a nearby private resort. Now, as that partnership has shown positive results, other Fijian resorts are looking to follow its lead. This month, MPA News examines this case and its lessons.

To protect rare colonies of glass-like, deepwater sponges, the Canadian Department of Fisheries and Oceans (DFO) has banned groundfish trawling at four sites off the Pacific coast of Canada. The non-contiguous sites - about 200 meters in depth and covering nearly 1000 km2 of seabed - will remain open to other fishing-gear types as DFO officials examine the compatibility of those gear types with sponge protection.
