Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Though they’re protected worldwide, great white sharks encounter longline fishing vessels in half of their range.
Even the remote open ocean offers no escape from industrial fishing for sharks.
New Zealand’s coastline spans a distance greater than from the south pole to the north pole.
New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.

Strictly enforced no-take marine areas benefit everyone, from the fish to fishers.
Marine protected areas are geographically distinct regions of the ocean that are given special protection under law.
A new network of 20 sites have been declared as marine protected areas in South Africa.
The West Moberly First Nation would like to see biodiversity-rich riparian areas in the Peace River Valley, in northeastern British Columbia protected. They will be destroyed by the Site C hydro dam, currently under construction.
Countries can protect biodiversity and recognize Indigenous peoples as conservation partners.
An effort to increase such areas can pose a particular threat to island overseas territories.

How can marine preserves best protect sea creatures that move in and out of them? Two ocean scientists describe new thinking about designing marine protected areas.
Nature offers many benefits to people.
Governments around the world have vowed to halt the loss of global biodiversity by 2020, but without more investment, we'll miss some of the targets.

Prime Minister Justin Trudeau has taken swift action on protecting marine areas over the past two years, but he'll need to continue this momentum if he is to cement his legacy.
Scientists call large marine protected areas effective tools for conserving sea life. But do they benefit countries that create them? Scholars explain how Palau's huge marine protected area seeks to protect resources for Palauans.

Palau has banned commercial fishing in most of its waters – while encouraging more foreign visitors.
A century after they vanished, oysters have returned to the Dornoch Firth thanks to an ambitious natural cleaning project
A NOAA vessel explores the the Northeast Canyons and Seamounts Marine National Monument, the first in the Atlantic Ocean.
One of the environmental legacies of the Obama administration is ocean reserves. Two ocean scientists explain why these are a critical but not sufficient piece of conservation.
Whitespotted surgeonfish (
Acanthurus guttatus), found in the Indo-Pacific, crop the upper portion of algae while feeding, preventing macroalgae from becoming established on reefs.
Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
Australia’s oceans are home to extraordinary marine life.
Australia has the third largest marine jurisdiction in the world, a vast ocean territory that contains important natural and biological resources. And it needs protecting.
Steven Morgan deploys ABLE robots in a swimming pool to test how well their programs simulate larval behavior.

Most ocean species start out as larvae drifting with currents. Using underwater robots, scientists have found that larvae use swimming motions to affect their course and reach suitable places to grow.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
