Should scientists avoid publishing shark migration data because it helps fishermen? Spoiler: No

Posted on July 1, 2013 By David Shiffman 15 Comments on Should scientists avoid publishing shark migration data because it helps fishermen? Spoiler: No
Conservation, Science

In recent weeks, some conservation activists have been promoting an idea that I would like to respond to as a member of the scientific community. They claim that scientists shouldn’t publish data about shark migrations, movement, or population dynamics because such data helps fishermen to find areas where there are lots of sharks and kill … Read More “Should scientists avoid publishing shark migration data because it helps fishermen?

A citizen science project to monitor sevengill sharks in San Diego

MikeyMichael Bear is  Science Diving Editor for California Diver Magazine and  currently contributor to Marine Science Today with over a 1000 cold-water dives, an AAUS (American Academy of Underwater Sciences) Scientific Diver and  founder of Sevengill Shark Sightings.org. He  lives and work  in San Diego.

 

I am not a professional shark researcher–just an experienced San Diego diver who has been diving in the San Diego area since 2000. In October of 2008, I began hearing reports of encounters between local San Diego divers and Sevengill sharks, (Notorynchus cepedianus).   At the time, I thought this a bit unusual, since this was the first I had heard of these encounters in nearly a decade of regular diving in the San Diego area and monitoring local Internet dive boards. Between 2000 and 2006, almost no encounters were reported. But in 2008, that all changed and they began appearing on  the dive boards and  lists, one here, two there, five there,  slowing increasing until it was obvious that something was happening–exactly what was not clear–only that more and more encounters were being reported by divers.

Then, in the summer of 2009, I had my own memorable encounter with a Sevengill.   I was diving off of Point La Jolla when a large seven footer glided majestically between me and my dive buddy, who was no more than two meters away from me.   To say we were startled would be an understatement.   It was this incident, along with the increase in reports by other divers, caused me to set up a website  later that same year,  allowing San Diego divers to log and document their encounters with this species, as a sort of  personal citizen science project, because  no local marine institution, including Scripps Institution of Oceanography and NOAA SW Fisheries in La Jolla, had ever done any baseline studies locally prior to this point–I know, because we checked.

The Sex Lives of Spoonworms: 10 marine animals with parasitic, dwarf, and otherwise reduced males

Posted on May 31, 2013September 19, 2013 By Andrew Thaler 8 Comments on The Sex Lives of Spoonworms: 10 marine animals with parasitic, dwarf, and otherwise reduced males
Science

Earlier this week, Fox News commentator and all-around terrific guy* Erick Erickson, while discussing a recent Pew Study that revealed that women were the sole breadwinners in 40% of US households that contain children, had this to say:

“I’m so used to liberals telling conservatives that they’re anti-science. But liberals who defend this and say it is not a bad thing are very anti-science. When you look at biology—when you look at the natural world—the roles of a male and a female in society and in other animals, the male typically is the dominant role. The female, it’s not antithesis, or it’s not competing, it’s a complementary role.”

I’m not sure where Erickson got his science education from, but it’s pretty clear he should have spent a little more time shopping around on the free market, because he sure is wrong. How wrong? I managed to assemble this list of 10 marine species with dwarf, parasitic, or otherwise reduced males (including an entire female-only class) while waiting for my toast**. So have a seat and let me show you how much weirder and more wonderful the world is than Erickson’s Disney-esque misinterpretation of biology.

1. Anglerfish

The deep-sea Anglerfish is among the most common examples of parasitic males in the marine world. Anglerfish comprise a variety of taxa in the order Lophiiformes. Almost all (females) possess a specialized appendage that acts as a lure to attract unwary prey. Life in the deep sea is rough–even though it is the largest and most diverse ecosystem on Earth, biomass is fairly low–so finding a mate is a struggle for these slow swimming fishes. The solution: carry your partner with you.

Male anglerfish are tiny, often less than 5% the size of the female, but they possess powerful olfactory receptors, allowing them to seek out females. Once a mate is located, the male anglerfish latches on to her abdomen, fuses his circulatory system with hers, and is then slowly digested until there’s nothing left but a sac of gonads surrounded by basic life-supporting tissues. Female anglerfish are not monogamous, either. At any given time she could be covered by a half-dozen parasitic males. Kinky.

The great #Mermaids Storify

This week, Animal Planet aired “Mermaids: The New Evidence”  the second fake documentary in their series about mermaids.  After complaining about the ridiculous show and the associated devastating effects on science literacy*, we decided to watch the re-air together and live-tweet it. The goal was to get real scientific information into the twitter conversation associated with the show. The Storify of our contributions to the discussion is below.

* Lots of people think that the admittedly fake documentary is real. Search the twitter hashtag #Mermaids and you’ll see literally hundreds of examples of this. These are not included in the Storify in the interest of not being cruel to strangers.

Last year, David and several other marine science bloggers debunked Animal Planet’s amazingly fraudulent mermaid foc-u-mentary (yes, I’m coining that term for fake documentaries that show absolute disdain for their audience. It’s not satire. It’s not parody. It’s a giant middle finger to the public).

U.S. government: shark fin bans “significantly undermine conservation and management of Federal shark fisheries”

I’ve written in the past about why shark fin bans might not be the best tool for the conservation and management of sharks. Though specific details vary, these so-called “blanket bans” typically make it illegal for anyone to buy, sell, or possess shark fins regardless of the source *. Additionally, to date most of these fin bans have taken place in a few U.S. states and Canadian towns. If the goal of these state-level fin bans is to reduce the supply of fins to the global market, proponents should consider that  according to TRAFFIC, more than 95% of the supply of shark products comes from countries outside of the U.S. and Canada.  Even if every U.S. state passed a fin ban, it would have a negligible  direct impact on global supply. Additionally, the United States has some of the most sustainably managed shark fisheries in the world (hammerhead sharks and a few others are an exception). We want other countries to emulate out management practices, not to remove our management practices from the global marketplace.

If the goal of these local fin bans is to reduce global demand, proponents should consider that the overwhelming majority of the demand for shark fin soup is in China and Southeast Asia, where passing such bans will pose a significant challenge. Some proponents of fin bans say (after the negligible impact on supply and demand is pointed out) that fin bans help with  “raising awareness of the problem of overfishing of sharks”. While these fin bans do result in (relatively) positive media coverage for shark conservation, “raising awareness” is not the publicly stated goal of these bans. If your goal is to educate people about a problem, educate people about the problem.

Instead of inflexible and ineffective fin bans that penalize fishermen who have adopted best practices * without impacting the global market, I’ve advocated for a science-based approach to sustainable shark management following the 10 basic principles in line with what has been laid out in the United Nations Fisheries and Aquaculture Organization’s International Plan of Action for Sharks and IUCN Shark Specialist Group guidance. These principles include banning finning of sharks by requiring that carcasses be landed whole (recall that finning is a specific fishing practice not synonymous with the fin trade), using science-based quotas to manage the fisheries of sharks whose populations can support a fishery, and restricting the harvest of species whose populations cannot.

Recently, the United States National Marine Fisheries Service (which, once again, manages some of the most sustainable shark fisheries on Earth) has started to officially speak out against state level fin bans.
