 Historical Overfishing and the Recent Collapse of Coastal Ecosystems
One possible explanation for Acanthaster outbreaks is that overfishing of species that prevy upon larval or juvenile stages of crown-of-thorns starfish is responsible for massive recruitment of the starfish (51).
The highly cryptic, predator-avoiding behavior of juvenile starfish, their formidable antipredator defenses as subadults and adults, and the reduction of some generalized predatory fishes on the Great Barrier Reef all point to such a "top-down" explanation.
Contrary to romantic notions of the oceans as the "last frontier" and of the supposedly superior ecological wisdom of non-Western and precolonial societies, our analysis demonstrates that overfishing fundamentally altered coastal marine ecosystems during each of the cultural periods we examined.

 The Ocean Conservancy:
One useful approach is to identify the best management practices that have produced success where it currently exists and to begin to utilize these approaches where management has been less successful.
For example, the New England groundfish fishery shows better success for individual stocks that utilize one of the best management practices, mortality constrained below MSY fishing rates (see figure 1).
To avoid confusion between the terms “overfishing” and “overfished,” the term “depleted” will sometimes be used to refer to stocks defined as overfished.

 Overfishing
It should be noted that this indicator does not capture fishing pressure from more remote locations or illegal fishing (see Chapter 2 - “Limitations of the Analysis” and Table 1: Reefs at Risk Analysis Method.
) In the region as a whole, the study identified about 60 percent of reefs as threatened by overfishing (with about 30 percent each under medium and high threat).
Overfishing can lead to short-term losses in biodiversity, the loss of species with critical roles in the ecosystem, and may also lower the resilience of the reef to other threats.

 oceans campaign, global overfishing
In its wake, fish populations are being dangerously depleted; nature's balance is being altered across vast areas of the world's oceanic ecosystems in ways that may be irreversible, and key species in the complex, diverse web of marine life are threatened.
Overfishing results in a form of ecological degradation or debasement, in which the naturally derived community of fish species changes.
The business of fishing must be redefined so that they might continue to provide nutritional and employment benefits to dependent communities in ways that do not risk the health and natural integrity of the ocean environment.

 Overfishing
It is human nature to try to make as much money as possible, but this has to be weighed against the economic hardship that whole communities have suffered as a result of overexploiting their own fisheries, not to mention the grave consequences of overfishing for fish populations.
Most of the problems associated with overfishing have been caused in the last 50 years by the rapid advances in fishing technology.
These are just a few examples of how overfishing can seriously affect not only the fish stocks, but also the livelihoods of many people who depend on fishing as a job.

"Overfishing seems to be the largest 'signal' that explains our data," Pandolfi said.
Historical evidence dating back thousands of years proves that overfishing, not recent coral diseases or other causes, is the main cause of the slow death of the world's coral ecosystems, marine paleontologist John Pandolfi of the Smithsonian's National Museum of Natural History and 11 other researchers say in the article.

But Fogarty said the issues should not be insurmountable.
This is what scientists call “growth overfishing.” It is different from what people typically think of as overfishing, where so many are harvested that it harms reproductive potential — something known as “recruitment overfishing.”

Bjorndal says scientists have missed the connection between past overfishing and current ecological problems in part because they don’t feel comfortable working with historical data, which may not conform to the rigors of scientific testing and experiment.
Despite such declines, the authors conclude on a cautiously optimistic note, saying most of the overfished species still survive in sufficient numbers to permit restoration.
While it’s true that past data may not be as complete as scientists would like, the resulting lack of historical perspective has often led to erroneous or incomplete conclusions about ecological problems, she says.

 Explanation of Growth Overfishing
Growth overfishing is much more common than recruitment overfishing, but it does not receive the attention given to recruitment overfishing because it does not pose such a serious threat to the continued existence of the resource.
But growth overfishing still reduces the potential yield from a fishery, and thus the economic and other benefits that could be obtained from the stock.
The total yield from the fishery is therefore less than it would be if the fishing mortality rate, or percent of the stock removed each year, were lower.
