Overfishing. Overfished US stocks, 2010 The ability of a fishery to recover from overfishing depends on whether the ecosystem's conditions are suitable for the recovery.
Dramatic changes in species composition can result in an ecosystem shift, where other equilibrium energy flows involve species compositions different from those that had been present before the depletion of the original fish stock. For example, once trout have been overfished, carp might take over in a way that makes it impossible for the trout to re-establish a breeding population. Global overfishing.

National Geographic. Ocean overfishing is simply the taking of wildlife from the sea at rates too high for fished species to replace themselves.
The earliest overfishing occurred in the early 1800s when humans, seeking blubber for lamp oil, decimated the whale population. Some fish that we eat, including Atlantic cod and herring and California's sardines, were also harvested to the brink of extinction by the mid-1900s.

According to a recent study, stocks of the biggest predatory species, such as tuna and swordfish, may have fallen by 90% since the 1950s. Another study, published last week in Science, suggests extinction is on the cards for many species. This matters for numerous reasons, not the least of which is that a lot of people rely on fish as part of their regular diet. About 3 billion of the Earth’s inhabitants get a fifth or more of their protein from fish—which means that fish are a bigger source of the stuff than beef is. The difficulty is, in part, a consequence of the problem known as the tragedy of the commons, whereby a commonly held resource is over-exploited. Until now, trying to stop this illegal trade has been more or less futile.
This promising system will work only if governments enforce existing rules. Overfishing. Save Our Seas Foundation. One in five people on this planet depends on fish as the primary source of protein.

Index Search - Find it now! Overfishing. Unsustainable fishing. As coastal and pelagic (open ocean) fisheries around the world have collapsed, fishing effort has shifted to the deep sea and previously unexploited fish species.
Here, overfishing can quickly deplete local fish populations - even within a single season. Some newly fished populations, such as monkfish, Patagonian toothfish, blue ling, and orange roughy, have already collapsed in some areas. There is insufficient data on other populations to determine what level of fishing is sustainable. At present most deep-water species are likely to be over-exploited - and as many as 40% of the world’s fishing grounds are now in waters deeper than 200m. Overfishing.

That is about to change with the announcement that Google is teaming up with the environmental group Oceania and remote sensing specialist SkyTruth to create Global Fisheries Watch, the first-ever global tracking system of its kind. Global Fisheries Watch will launch next year and monitor commercial fishing around the world. The platform - a prototype of which was unveiled Friday at the International Union for Conservation of Nature World Parks Congress in Sydney, Australia - will leverage GPS data used by 100,000 ships worldwide. "But now, satellite data is allowing us to make human interaction with the ocean more transparent than ever before. "We can bring them back with good management. . © 2014 CBS Interactive Inc.
