The demand for shark fins is widely recognized as one of the major contributors to shark mortality around the world. However, solutions to decrease this demand are hotly debated, especially in the scientific community. Southern Fried Science and other websites have published opinions that debate the effectiveness of shark fin bans, but as a shark scientist working to implement this policy I would like to present the case for shark fin trade bans.

The conversation is newly relevant with the introduction of the Shark Fin Trade Elimination Act in the Senate on March 30^th by Senators Cory Booker (D-NJ) and Shelly Moore-Capito (R-WV) and in the House on March 9th by Representatives Ed Royce (R-CA) and Gregorio Kilili Camacho Sablan (I-MP). If passed, the bill would ban the buying and selling of shark fins in the United States – thereby removing the United States from the global shark fin trade altogether. The bill is championed by Oceana, where I work as the scientist on the sharks campaign.

The demand for fins fuels finning – the act of slicing off a shark’s fins and dumping the body back into the ocean. The United States recognized this practice was a problem and implemented the Shark Finning Prohibition Act of 2000 followed by the Shark Conservation Act (SCA) in 2010, which required that all sharks must be landed with their fins naturally attached (except for smooth dogfish, which can be landed under a fin-to-carcass ratio). However, according to the National Marine Fisheries Service, the United States is still importing fins from places like Hong Kong, China, New Zealand, the Netherlands, Spain, South Africa and Indonesia, to name a few. Not all of these countries have anti-finning laws, which means that the United States may be, and likely is, purchasing fins from finned sharks. Once in the United States market, there is no way to tell whether a fin came from a finned shark or not. By purchasing these fins, the United States is sustaining the demand for this unsustainable practice.

The time to defend the EPA is now!

Executive Order 13777 created a Regulatory Reform Task Force to oversee the evaluation of existing regulations to make recommendations about potential repeal, replacement, or modification to the Environmental Protection Agency. The dissolution of the EPA would be catastrophic for this country. Fortunately, the wheels of bureaucracy turn slowly, and before any recommendations are formally issued, … Read More “The time to defend the EPA is now!” »

Invasive species, overfishing, ocean plastics, wildlife tracking, and measuring ecosystem services, are some of the most daunting challenges in conservation.While these challenges require a combination of social, commercial, and regulatory cooperation to address, they can also be tackled through technological innovation, which can bypass some of the largest hurdles to implementing practical, timely solutions.

On April 21, 2017, 18 teams of conservationists, technologists, makers, and hardware hackers will gather in Washington DC and tackle five conservation challenges selected by a panel of experts at the Make for the Planet, part of the Smithsonian’s Earth Optimism Summit. Over three days, teams will work to develop prototypes, strategic frameworks, and model systems that address specific issues within the broader challenge prompt of terrestrial species invasion, overfishing, ocean plastics, wildlife tracking, and ecosystem services.

Please don’t ride sharks, and other great tips from the new guide to responsible shark diving

Shark wildlife tourism* is a growing marine industry with big implications for shark conservation. While there are many competing definitions, generally shark wildlife tourism refers to SCUBA dive operators who offer trips that guarantee that you’ll see sharks, often through the use of bait or chum to attract sharks to the divers. This has become a contentious issue in marine science and conservation circles. That’s why last week’s news that WWF, Project AWARE, and the Manta Trust released the first-ever guide to responsible shark and ray tourism best practices is so welcome. This thorough and well-researched guide guide is designed for dive operators who want to minimize their potential harm to sharks and rays while maximizing the potential conservation benefits of shark wildlife tourism.

Conserving Chicago’s Lungfish Legacy

On Sunday, February 5, 2017, Granddad the Australian Lungfish, the oldest fish in any aquarium or zoo, was euthanized due to health complications. Although his exact age is unknown, he arrived at Shedd Aquarium in Chicago as an adult in 1933. Australian Lungfish (Neoceratodus forsteri) take over a decade to mature, so we can estimate he was over 90 years old when he passed.

The Australian Lungfish is a unique species, considered a “living fossil”, resembling its ancestors whose lineage dates back over 380 million years. The Australian Lungfish genus (Neoceratodus) itself has been around for about 100 million years. When first described, they were believed to be amphibians; one look at their elongate body and flipper-like fins, and you can imagine the classification conundrum. The fish even possesses a primitive lung, allowing it to breathe air in low-oxygen environments (although they usually breathe with their gills).

Making global conservation conferences accessible in an world of increasingly restrictive travel.

We have a problem in conservation biology (ok, to be fair, we have a lot of problems, but this is one of them). The biggest environmental challenges–climate change, ocean acidification, over-fishing, agricultural runoff, species invasion, and myriad other emergent issues–are global challenges. They respect no borders and require a cohesive, multinational response. Researchers, stakeholders, and conservation managers, on the other hand, are increasingly impeded in their work by more and more restrictive barriers to travel.

This isn’t new. The Global South has often been excluded from major international conferences hosted in European and American cities, which are expensive and hard to get to. Onerous visa restrictions from and to a multitude of countries have been in place for decades, but the events of this week have made it clear that scientific societies need to plan for and provide alternatives to a membership that may not be able to travel to a conference yet still need to participate.

How Millard Fillmore reshaped the oceans in a quest for guano.

January 10, 2017January 11, 2017 Andrew Thaler

The numbers are in, and over the last eight years, President Barack Obama has protected more ocean than any other president in history. His expansion of NOAA and implementation of a National Ocean Policy will impact ocean health and fisheries management for generations. By almost any measure, he has had the biggest impact on the ocean of any modern presidency. Which raises the obvious question: is President Obama the most influential ocean president in history? Not by a long shot. That honor has to go to the president who’s policies have fundamentally shaped and reshaped how we view and control ocean territory, who laid the foundation for almost all the ocean protections we currently enjoy, and who set the precedent for the American Empire. That man is President Millard Fillmore, and he did it all for bird poop.

Agricultural science is beginning to understand that soil is not just soil, but a collection of nutrients that are slowly drawn from the ground by growing crops. Nitrogen, phosphorus, and potassium are crucial ingredients. The Industrial Revolution is pushing agriculture away from passive crop re-nourishment processes and towards intensive, fertilizer-driven farming. Fertilizer producers can’t keep up. At the same time, the American whaling industry had reached its zenith and began to fall. Coastal whales were harder to find and the bold men of Nantucket ventured out across the Pacific in search of the last great whaling grounds.

In these voyages, the whalers found numerous tiny, often uncharted islands in the Pacific. These remote islands were refuges, not just for weary sailors, but for generations of seabirds. From these seabirds rose great mountains of guano, guano rich in the nutrients plants crave. Guano was the solution to the fertilizer crises.

When I talk about Climate Change, I don’t talk about science.

Climate Change is real. It’s happening now. And the best available data points to us as the cause.

That the foundational science is settled is a point of unending frustration to scientists, science writers, and policy advocates who face continuous partisan push back, from whitewashing government websites to threatening scientists with legal repercussions for reporting the data. During my International Marine Conservation Congress keynote last year, I argued that Climate Change denial is not a science literacy problem, but rather a product of increasing political bifurcation. Political ideology is a much stronger predictor of Climate Change understanding than science literacy.

The term “Climate Change” is now loaded with so much political baggage that it becomes almost impossible to hold a discussion across political lines. In stakeholder interviews, people generally understand and acknowledge the impacts of climate change on local and regional scales, as long as you don’t call it “Climate Change”. This has been my experience working in rural coastal communities, which tend to be strongly conservative and intimately connected to the changing ocean.

Which is why, when I talk about Climate Change, I don’t talk about science.

Deep-sea Researchers Support Nomination of the Marianas Trench Marine National Monument as a UNESCO World Heritage Site

Early this December, the National Park Service announced that the Marianas Trench Marine National Monument made the short list for UNESCO World Heritage designation. Though hidden beneath the water’s surface, the Mariana Trench, a unique geologic and ecologic landmark and a natural treasure, dwarfs the Grand Canyon in scale and scope.

The Mariana Trench is more than a mile deeper than Mt. Everest is high and hosts Challenger Deep, the deepest point on Earth. It is also home to numerous sites of exceptional scientific value, including submerged volcanoes that host deep-sea hydrothermal vents, the largest documented mud volcanoes, coral atolls and fringing reef ecosystems that support apex predators like sharks and whales, as well as habitat-forming stony corals.

Fun Science FRIEDay – Harnessing Synthetic Biology to Fight Ocean Pollution

Plastics, more importantly microplastics, clog our oceans. This phenomena in the ocean has been likened to smog around cities. These plastic particles are dangerous because they can absorb toxins, subsequently be consumed by zooplankton and invertebrates, and bioaccumluate up the food web to fish that are consumed by humans. A study in Nature found that 25 percent of seafood sold contains microplastics! There has been a recent awareness of the unseen harm that exists when plastic pollution in the ocean degrades into microplastics. A report in Environmental Research Letters estimated that “accumulated number of micro plastic particles… ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons.” That is cray cray. Despite a better awareness of the impact of microplastics on marine ecology, we still have a poor spatial understanding of microplastics in the ocean. The presence and density of microplastics is determined by trawling the ocean (i.e., researchers go out with a net and physically count the pieces of plastic they pick up). As you can imagine, this is not very effective.
