Fisheries expert and executive director of Institute for Ocean Conservation Science at Stony Brook University presents assessment of current fisheries management in the journal Science
In a Perspectives article, “The Risks of Overfishing,” published online today in the October 26 issue of the journal Science, Dr. Ellen K. Pikitch, executive director of the Institute for Ocean Conservation Science and professor at Stony Brook University, cautions against continuing traditional fisheries management. According to Dr. Pikitch, current and recent studies demonstrate the need for “a more precautionary approach to fisheries management, in which fishing is restricted to those places and amounts where it can be conducted safely and with minimal risk of jeopardizing the integrity of marine ecosystems.”
Commenting on a study published in the same issue by Costello et al., which found that globally, the abundance levels of fish populations are well below those recommended by conventional fisheries management guidelines, Dr. Pikitch writes, “Of even greater concern, most species are on a continuing trajectory of decline.” Costello et al. found that fisheries that represent 80 percent of the world’s catch are in worse shape than those than those on which global status reviews have been conducted. Dr. Pikitch writes, “Costello et al.’s findings are even more alarming in the context of the evolving understanding of fishing and its ecological effects.” Dr. Pikitch explains that traditional fisheries management focuses on obtaining maximum sustainable yield (MSY), which is a single-species approach that does not take into consideration the effects of the fishing on the entire ecosystem, including declines of other fish and marine animal species.
The findings of a recently published report, “Little Fish, Big Impact: Managing a Crucial Link in Ocean Food Webs,” by the Lenfest Forage Fish Task Force, found that moving away from a single-species management approach toward an ecosystem-based approach requires more precautionary management. The task force, of which Dr. Pikitch is the chair, determined that the amount of information available about the ecosystem and the fishery should establish the level of precaution managers should apply, requiring a shift in the burden of proof for fisheries management. In the Perspectives article, Dr. Pikitch writes “[This shift] is justified not least because the risks of continuing fishing when it results in serious negative consequences are generally much greater than the risks of curtailing fishing when it does not have a deleterious impact.”
The Institute for Ocean Conservation Science at Stony Brook University is dedicated to advancing ocean conservation through science. The Institute transforms real-world policy while pursuing serious science, both of which are essential for ocean health. For more information, go to www.oceanconservationscience.org.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
