PolitiFact calls claims of menhaden declines “Mostly False”, is completely wrong

Despite their small size and plain appearance, menhaden have been called “the most important fish in the sea” because numerous coastal fish species rely on them for food. Although they aren’t typically eaten by humans, there is still a huge fishery for them for bait, aquaculture food, and oil. That fishery has been essentially unregulated, allowing fishermen to take as many as they want. Recently, there’s been a campaign among certain environmental groups to fix this problem and put catch limits in place for menhaden.

I was surprised to see PolitiFact, a non-partisan political fact-checking website, address this issue. I’ve checked PolitiFact pretty regularly for years, and I’ve never seen them cover a topic like this before. They focused on a claim by the Pew Environment Group that “In recent years, menhaden numbers along our coast have plummeted by 90 percent.” While I admit I am not familiar with specific details of menhaden population trends,  anyone who has paid any attention at all to the ocean knows that we’re overfishing at alarming rates. According to the UN Food and Agriculture Organization, approximately 1/3 of all global fisheries are depleted or overexploited, many by more than the 90% referenced for menhaden. Shockingly, PolitiFact called the claim by Pew “mostly false”. Their reasoning for this ruling is even more ridiculous than the ruling itself:

Math is hard: the use of complex equations decreases the chance a paper will be cited

Figure 1- math is hard

How many of you asked “when am I ever going to need to know this” in math class? While basic mathematical literacy is essential for life in the modern world, most people can achieve success in their careers if they can’t remember the difference between pi and apple pie.

One of the exceptions to this comes from my own career path- scientists absolutely, positively need to have strong quantitative skills in order to perform research. However, many scientists struggle with math.  I can’t even count how many conference presentations I’ve attended that included a statement along the lines of “don’t worry about all the complicated equations here”, or how many students or journal club attendees have told me that they just skipped over the section of a paper focusing on models and equations.  See what I did there? Can’t even count? Anyway, while math may be more directly relevant to our jobs than it is to some of yours, we still find it hard.

The New England Fishery Management Council‘s Groundfish Advisory Panel (GAP) met recently in Peabody, Massachusetts to discuss plans and priorities for the coming year. NEFMC, one of 8 fisheries management councils in the United States established by the Magnuson-Stevens Fishery Conservation and Management Act, is tasked with creating management plans for local fisheries, which must be … Read More “New England Fishery Management Council calls for “legal way to kill more elasmobranchs”” »

Presidential Endorsement: On ocean conservation issues, the choice is clear. Obama 2012

On Tuesday, after what seems like an eternity of campaigning, millions of Americans will head to the polls to vote for our next President. Voters will consider numerous important issues, such as the economy, national security, and the endorsement of Lindsay Lohan. Recent polling indicates that Americans are split, and the election is expected to be very close. On an issue near and dear to my heart, the conservation of the ocean and marine life, one candidate is by far the best choice. I endorse President Barack Obama for re-election.

After promising to “restore science to its rightful place” in his 2009 inauguration speech, there are indeed many successes in conservation and science that President Obama can boast of. He has invested unprecedented amounts of Federal money in alternative energy sources, which, despite the bankruptcy of a few companies, will help reduce greenhouse gas emissions and combat climate change and ocean acidification- as will increased fuel efficiency standards. Early action resulted in conservation of wilderness rivers and trails, and Federal Everglades restoration funding has increased. Restrictions on stem cell research were greatly reduced, and mercury pollution was restricted by the EPA. Race to the top programs have improved science and math education in several states.

On ocean issues, the Obama administration has  been a leader domestically and internationally. For the first time, the United States has a National Ocean Policy, which aims to reduce conflicts between different ocean stakeholders. President Obama signed both the Shark Conservation Act and the Billfish Conservation Act, which, despite being imperfect, are strong legal tools to protect charismatic and ecologically important top predators- and numerous other successes in improving the management of U.S. shark fisheries are detailed here. The Obama administration has aggressively pursued fisheries conservation internationally, at CITES, regional fisheries management organization meetings, and the Convention on Migratory Species.

The journal Brain, Behavior, and Evolution has just released a special issue on the nervous systems of cartilaginous fishes (sharks, skates, rays, and chimeras). The six research articles contained in the special issue  both summarize and greatly expand what’s known about elasmobranch brains. Dr. Kara Yopak, an elasmobranch nervous system expert who served as the editor … Read More “New special issue of elasmobranch nervous systems “highlights the evolutionary relevance” of sharks and rays” »

Are sharks ecologically important? Fact-checking another idiotic anti-shark rant from Paul Mulshine

Posted on October 3, 2012October 2, 2012 By David Shiffman 9 Comments on Are sharks ecologically important? Fact-checking another idiotic anti-shark rant from Paul Mulshine
Conservation, Science

The government of Western Australia recently announced a plan to kill great white sharks that come close to popular swimming beaches, resulting in justifiable outrage from the scientific and conservation communities. I’ve written before (here and here) about why this is a bad idea that will harm a species in need of  protection without making the ocean significantly safer for humans, and won’t rehash the details here. Instead, I want to focus on a claim recently made in support of this plan by Paul Mulshine, best known for taunting environmentalists by stating that shark fin dumplings would taste better if only more sharks were killed.

In a recent blog post on the subject, provocatively titled “Aussie’s common-sense approach to great white sharks has shark huggers’ jaws flapping” , Mulshine makes a lot of wildly inaccurate claims about great whites, shark attacks, and shark conservation.

Last Wednesday morning, the Fisheries Committee of the European Parliament voted on proposed amendments that would, if passed, form their response to the European Commission’s 2011 proposal to end all removal of shark fins at sea (and thereby close loopholes in the EU finning ban).  As the EU is the single largest supplier of shark fins to … Read More “What the $&!* happened?
