A growing body of scientific evidence that demonstrates what we at Greenpeace have been saying for a long time: that the establishment of large-scale networks of marine reserves, urgently needed to protect marine species and their habitats, could be key to reversing global fisheries decline.

Marine reserves can benefit adjacent fisheries from both the 'spillover' of adult and juvenile fish beyond the reserve boundaries and through the export of eggs and larvae. Inside the reserves, populations increase in size and individuals live longer, grow larger and develop increased reproductive potential.

Marine reserves could even benefit highly migratory species, such as sharks, tuna and billfish, if reserves were created in places where they are currently highly vulnerable, such as nursery grounds, spawning sites or aggregation sites such as seamounts.

Large-scale marine reserves are areas that are closed to all extractive uses, such as fishing and mining, as well as disposal activities. Within these areas there may be core zones where no human activities are allowed, for instance areas that act as scientific reference areas or areas where there are particularly sensitive habitats or species.

Some areas within the coastal zone may be opened to small-scale, non-destructive fisheries providing that these are sustainable, within ecological limits, and have been decided upon with the full participation of affected local communities.

Marine reserves are not just about overfishing -even if one of the primary reasons for creating marine reserves is preserving fish stocks. They are increasingly seen as an essential global tool to protect the marine environment, including from pollution -caused particularly by the disposal of wastes (radioactive wastes, munitions and carbon dioxide).





Marine reserves news

Mediterranean pirates busted by Greenpeace

Activists aboard our ship Arctic Sunrise confronted an illegal vessel, the Luna Rossa, fishing with a driftnet this morning in international waters west of Sicily in the Mediterranean Sea. The Luna Rossa’s crew immediately cut the net and fled from our ship at high speed.

In the Red - fish that are best left in the ocean

Far too often, we're left without answers when we're trying to find out if seafood on our supermarket shelves is sustainable -until recently it's been almost impossible to know. Now we are providing an international red list of fish that both consumers and retailers should avoid.

It's beginning to look a lot like World Oceans Day

It's that time of year again. People worldwide are scurrying about making last minute preparations for World Oceans Day on Sunday -- trimming the coral and hanging out their scuba socks. Father Neptune is checking his list of good children who have only eaten pole-caught sustainable fish all year, and hitching up his conch shell chariot's team of eight tiny seahorses. And we at Greenpeace are doing our part with ships in the Pacific Ocean and the Mediterranean Sea, activists on land pressuring seafood suppliers and retailers to go sustainable, and, in the sky, Google Earth giving people a birds' eye view of the solution to saving our seas: a global network of marine reserves.

Greenpeace vessel attacked

Three Turkish tuna fishing vessels surrounded the Greenpeace ship Arctic Sunrise in the Cypriot Channel, with crew from one vessel attacking the ship with lead weights. Greenpeace is in the area to call for an end to unsustainable fishing and to call for the establishment of a marine reserve between Cyprus and Turkey.

World's largest tuna destroyer

We chased it for 5 days, but as dawn broke over the Pacific this morning we finally confronted the biggest tuna fishing vessel in the world. The Spanish-owned and flagged tuna purse seiner "Albatun Tres" is known as a 'super, super seiner' and can net 3,000 tonnes of tuna in a single fishing trip. This is almost double the entire annual catch of some Pacific island countries.

Pacific islands act to save tuna

Finally, some good news for tuna stocks and a first step towards protecting the Pacific Commons for future generations! Eight Pacific island countries have taken the most significant action ever to combat overfishing in the region.

Pirate of the Pacific busted by Greenpeace

We caught an illegal tuna purse seiner (Queen Evelyn 168) in the Pacific Commons on Friday. This Philippines-flagged vessel was close to the transfer of tuna between her sister vessel and a refrigerated mothership. It was likely that transfer of fish at sea, involving this illegal vessel, was about to occur. But upon our arrival the vessels immediately separated and fled.

Fishing out the Pirates of the Mediterranean updated

Just a few days into our three-month “Defending Our Mediterranean” tour, and already the Arctic Sunrise has come face-to-face with pirates. In the early hours of the morning, we confiscated almost two kilometres of illegal driftnet, containing dead, undersized bluefin tuna - and a small sea turtle.

Greenpeace frees ocean life from Pacific longliner

The Greenpeace ship Esperanza freed tuna, sharks, marlin and an endangered sea turtle from a Taiwanese longliner on Saturday. The vessel was fishing in the Pacific Commons, the international waters we want to see protected as a marine reserve.

Defending our Mediterranean tour launches

The Mediterranean Sea is a global treasure. Rich seagrass meadows and rocky reefs dominate its coastal zone while an awe-inspiring array of underwater mountains (seamounts), cold seeps and trenches are found on its seabed.
