Marine Reserve declared in the World's Aquarium

Marine reserves

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.

Overfishing

Many marine ecologists think that the biggest single threat to marine ecosystems today is overfishing. Our appetite for fish is exceeding the oceans' ecological limits with devastating impacts on marine ecosystems. Scientists are warning that overfishing results in profound changes in our oceans, perhaps changing them forever. Not to mention our dinner plates, which in future may only feature fish and chips as a rare and expensive delicacy.

Bycatch

Many fisheries catch fish other than the ones that they target and in many cases these are simply thrown dead or dying back into the sea. In some trawl fisheries for shrimp, the discard may be 90 percent of the catch. Other fisheries kill seabirds, turtles and dolphins, sometimes in huge numbers.

Shrimp farming

Over the last few decades shrimp farming has been a relentless destroyer of huge expanses of tropical coastlines, particularly mangrove forests. Mangrove forest roots are bulldozed into the mud to make way for the intruding shrimp farms. The coastal equivalent of terrestrial rain forests, mangroves are home to an incredibly diverse range of life. They are breeding grounds and nurseries for many fish, shellfish and other wildlife. Shrimp farming turns them into a barren and toxic prawn cocktail.
