Bottom trawling and the importance of plaice

Posted on July 27, 2010December 20, 2011 By Andrew Thaler 7 Comments on Bottom trawling and the importance of plaice
Conservation, Science

“The commons petition the King, complaining that where in creeks and havens of the sea there used to be plenteous fishing, to the profit of the Kingdom, certain fishermen, for several years past have subtily contrived an instrument called the “wondyrechaun” made in the manner of an oyster dredge, but which is considerably longer, upon which instrument is attached a net so close meshed that no fish, be it ever so small which enters therein can escape, but must stay and be taken.

And that the great and long iron of the wondyrechaun runs so heavily and hardly over the ground when fishing that it destroys the flowers of the land below water there, and also the spat of oysters, mussels and other fish upon which the great fish are accustomed to be fed and nourished. By which instrument in many places, the fishermen take such quantity of small fish that they do not know what to do with them; and that they feed and fat their pigs with them, to the great damage of the commons of the realm and the destruction of the fisheries, and they pray for a remedy.”

Petition by the Commons to King Edward III, 1376 (from The Unnatural History of the Sea)

This petition, penned in 1376, reveals a depth of understanding that we often don’t attribute to 14th century fishermen. Habitat destruction, overfishing, bycatch, even common pool resources are all clearly described here. In it, the Commons protests a new and efficient, though inaccurate fishing tool, the ‘wondyrechaun’, and begs King Edward III to ban it. This is the first historical record of the ‘wondyrechaun’, what today is called a beam trawl. Everything you need to know to understand why the world’s fisheries are in trouble is contained within the single fact that, in 1376, at it’s very inception, the people begged the king to ban it’s use, and 700 years later, the beam trawl survives.

Dolphin-safe tuna: conservation success story or ecological disaster?

Posted on July 26, 2010December 31, 2011 By David Shiffman 49 Comments on Dolphin-safe tuna: conservation success story or ecological disaster?

I used to feel warm and fuzzy inside when I saw the dolphin-safe logo on my tuna. I felt like a decision I made was helping the environment- like I was making a difference.

 

The commonly believed narrative about dolphin-safe tuna goes something like this: Lots of dolphins were being killed by tuna fishermen, outraged environmentalists led a massive PR campaign, legions of adorable children wrote to their elected officials, elected officials changed the rules to protect dolphins, and everything is better now. Hooray, we saved an innocent species and helped the environment!

That narrative is a great story. It shows that if a few people who care can convince others that their cause is just, there’s no limit to what we can accomplish. It’s inspiring. Too bad it’s not really true. As it turns out, we made things worse- a LOT worse.

Adventures with Citizen Science: perspectives of a shark biologist

Those of you who follow me on Twitter or are friends with me on facebook may have seen that last month, I asked for volunteers to come catch and tag sharks with me here in Charleston. While I was pleased by how excited respondents were for this opportunity, I would be remiss if I didn’t acknowledge that involving members of the public in scientific research is an old idea. It’s called Citizen Science.

Philosophy of activism: comment “swarming”

In my ongoing Philosophy of Activism series, I describe tactics used by various advocacy organizations and solicit feedback from our readers to determine if those tactics are effective or not. For the latest edition, I wanted to pick all of your brains about a tactic that I personally used this week.

Beyond the Ivory Tower: Experts in the Masses

This is a reposting from our old website.  I encourage you to take a look at the comments here before writing your own new ones.

Living among a community comprised largely of scientists and fishermen has recently made me wonder where the dividing line between scientist and citizen falls.  A recent discussion at Science Online 2010 also raised the question of what is the role of the Ivory Tower in research?  Should we consider the scientific community more broadly or is there really something to be said for the role of the ‘expert’ as certified by degrees and a corner office at an academic institution?

Just some food for thought – a picture really says 1000 words here. What you may not be able to see is the conservation areas completely covered up by the dots representing hog lagoons.

Whale Quotas and Sea Shepherd

Posted on June 30, 2010June 30, 2010 By Andrew Thaler 37 Comments on Whale Quotas and Sea Shepherd
Conservation, Popular Culture, Science

We sparked a good debate over the effectiveness of direct action conservation movements over at the post “Is Sea Shepherd really saving whales?” One of the most difficult questions raised was if Sea Shepherd wasn’t there, would the Japanese make their full quota? The data presented in that post was inconclusive, because the quota increase corresponded to the beginning of SSCS’s Southern Ocean campaign, so we have no time period in which the Japanese quota was increased while Sea Shepherd was absent.

Ghosts in the Molecular Machine

The extent of migration among populations drives population structure. With enough migration, populations become homogeneous and behave as a single larger population. As migration rates decrease, populations drift apart and become differentiated. By measuring the amount of differentiation, we can determine the extent of migration between them. But what happens when there are unsampled populations also exchanging migrants?
