Sounds kinda weird.. but studying nearly identical coral reef systems off Australia, my collaborators and I discovered something unusual on the reefs subjected to nearly exclusive fishing of sharks—fish with significantly smaller eyes and tails. This provides evidence of body shape changes in fish due to human-driven shark declines from overfishing. In the study, our…

Policy debates about the growing body of evidence showing that our oceans are on the decline tend to overlook one important detail: Ailing seas hurt the economies of all nations—large and small, landlocked and maritime. That makes it vital that political and business leaders around the world recognize this threat to the global economy and…

Marine tourism is now considered a “new frontier of late-capitalist transformation”, producing more revenue than aquaculture and fisheries put together. For many coastal communities, this industry is becoming the most significant economic activity. Marine tourism spans from simple operations run by one or few people (charter fishing boat operators, sea kayak tour guides, scuba diving…

Recently one of my peers referred to doing more conservation as addressing the problem of how to take marine protection to scale.  Covering nearly 70% of the planet and home to thousands of species of plants and animals, the ocean certainly represents a huge management problem. For some marine conservation funders, global scaling of marine…

Earlier this month, Indonesia announced the world’s largest sanctuary for manta rays. At the World Ocean Summit Tuesday, Peter Seligmann, the CEO of Conservation International, said the sanctuary “was not done out of good will, it was done out of enlightened self interest.” Seligmann said Indonesia had made careful calculations about how much manta rays…

The editor-in-chief of The Economist, John Micklethwait, asked a packed room at the World Ocean Summit if they thought the ocean was in worse shape now than when the conference was first held in 2012. Almost everyone held up a pre-printed red card that read “yes,” leading Micklethwait to say that the room had responded…

By Erick Ross Salazar, MarViva MarViva Foundation and Mission Blue have teamed up to seek protection for a high seas “hope spot” called the Central American Dome (CAD). A term coined by Mission Blue founder Sylvia Earle, hope spots are areas of particular conservation concern beneath the waves. The Central American Dome is a biodiverse,…

For several years now, I have been using electronic tagging to study the movements and behaviors of sharks. You can find out more about this research HERE and watch a video HERE.   I previously wrote about the state of electronic tagging and tracking marine animals. However, recently there have been a lot of myths,…

Understanding and predicting animal movement is important as it is central to establishing effective management and conservation strategies [1]. Until relatively recently, studying the movements and behaviors of highly migratory marine species (turtles, sharks, whales, penguins, seals and billfish) have been challenging due to the logistical and technological constraints of working in aquatic environments. However,…

Shark Declines: Fuel for a Decade of Conservation Effort by Austin J. Gallagher & Neil Hammerschlag     Scientists have been studying the population status of sharks for years and while the vulnerability, threatened status and biological importance of sharks has long-been well-recognized and documented by the research community (1), ten years ago, shark conservation…

U.S. policymakers know they need to limit the number of Atlantic bluefin tuna caught and killed by surface longlines, which can stretch 40 miles with more than 750 baited hooks and float unattended for up to 18 hours. After all, the western Atlantic bluefin population is down 64 percent from its level in the 1970s,…

We’ve covered marine protected areas (MPAs) a lot in Ocean Views. They come in different flavors and can have different goals, although the basic idea is designating part of the ocean with some kind of legal protection against harmful activities like overfishing or drilling for oil. Today, a new study published in Nature Communications found that…

Around the world, more than a billion people rely on seafood for a significant part of their protein. And yet the United Nations has projected that by 2030, there will be a 40 million ton seafood shortage. Some experts have therefore been pointing increasingly to aquaculture as a means to provide protein, while reducing stress…
