Overfishing: A Global Challenge

Living Oceans Society

Marine Protected Areas of the United States

Should large areas of the ocean be off-limits to fishing?

As this ScienCentral News video reports, that’s the hope of one leading scientist writing in the journal Nature.


Fishing Ban

It’s hard to imagine the vast oceans of the world being limited in their ability to provide us with fish. But some fishing areas, or “fisheries”, have already collapsed and marine biologists say we may be making ocean fish populations disappear from other areas as well. Because of this, some say fishing should be banned from large parts of the ocean.

Daniel Pauly, professor at the Fisheries Centre at the University of British Columbia, is telling the world in journals like Nature that fish stocks in the oceans are plummeting, and that the only way to replenish them is to ban fishing in certain areas. This would allow the fish to grow, breed, and replenish. “We will actually catch more if we fish less,” Pauly explains. “One reason we are catching less is that we have overfished.”

Many theories have been advanced regarding a drop in the number of fish. They range from pollution to global climate change to other sea life. But Pauly—who helped create FishBase, a website that has information on 27,000 fish species—places the blame squarely on the increased mechanization and technological advances available in fishing. He says if you compare fishing to hunting, you can see the problem. “If you’re hunting rabbits,” says Pauly, “and there are fewer rabbits because there are too many hunters, nobody would say, ‘Let’s have bigger guns.’ Yet this is exactly what happens with fisheries. We have bigger boats, because a ‘boat’ is actually a ‘gun’.”

Pauly told Nature that the effect of fisheries on marine life is equivalent to that of a large meteor strike on terrestrial life. He advocates setting up Marine Protection Areas (MPAs) with “no-take” reserves to limit the amount of fishing in oceans. Right now, only 0.1 percent of the world’s oceans are protected, but Pauly believes that about 30 to 50 percent of the world’s oceans should be put aside in MPAs. “[The fish] would come back, they would be thankful,” he says. “They do respond. If you close an area, the fish come back.”

Not Everyone Agrees

Bob Thorstenson, president of the United Fishermen of Alaska, is a fourth generation Alaskan salmon fisher who does not agree that all fisheries are in trouble. “On an annual basis we harvest approximately 10 times more wild salmon than we harvested 30 years ago. The populations of wild salmon in most regions of Alaska are at extreme highs, historical highs never before seen.”

He says a ban on fishing would have a direct effect on one group of people—those who fish for a living. “We are a fishing nation in Alaska,” says Thorstenson. “Commercial fishing is the largest employer in the state of Alaska, the second largest revenue generator behind oil. We will not have doctors, scientists, or environmental groups implement some type of statewide program in Alaska from outside just based on their desires to see Alaska protected from Alaskans. We’re going to use the best available science, the best research, and the best technology to determine those times and those areas where it makes sense to harvest, and those times and places where it doesn’t.”

Pauly's Sea Around Us Project, funded by the Philadelphia-based Pew Charitable Trusts, is investigating the impact of large-scale fisheries on marine ecosystems.
