Vast and inaccessible, the oceans are difficult to comprehend and are rarely at the centre of our attention. Nor do they have advocates or lobbyists. This is quite remarkable, since the oceans crucially determine our climate and are an increasingly important source of our food. In order to raise public awareness of the interrelationships in marine science and thereby contribute to a more effective protection of the seas, mareverlag founded the non-profit company maribus in 2008. Maribus’s mission is to boost awareness of the oceans; it pursues no commercial interests. The “World Ocean Review” is a unique compilation presenting the state of our oceans and encapsulating cutting-edge science. It was made possible by the cooperation of various partners >
The fourth edition of the World Ocean Review (WOR) focuses on sustainability and explores how that concept can guide the management of our marine environment. WOR 4 explains the key ecosystem services supplied by our seas and identifies the main threats to them. It offers an overview of current marine policy at regional and transnational level and shows how conservation and sustainable use of our oceans can be reconciled in future.

IMPACTS OF OVERFISHING ON MARINE ECOSYSTEMS IN THE NORTHWEST ATLANTIC OCEAN
So, What is Overfishing?
Overfishing occurs when fish are caught in substantial numbers, at a rate faster than what the population can replace through natural reproduction. This leads to difficulties for species to successfully reproduce and maintain viable numbers for their survival; this negatively impacts other species, which interact in marine ecosystems.
- According to marine ecologists, “overfishing is the greatest threat to ocean ecosystems today, and scientists agree that at current exploitation rates, many important fish stocks will become extinct from the system within 25 years”
- “Since 1950, with the onset of industrialized fisheries, we have rapidly reduced the resource base to less than 10% for entire communities of these large fish species from the tropics to the poles” (Ransom Myers & Boris Worm)
