Spiny Dogfish Ecotourism?

One of the biggest challenges in conservation has been making the continued existence of a species or environment worth more than its value as food, real estate, or any other consumptive use.  Like it or not, some policymakers and populations will not  be convinced without…

Predation

A quick look around this blog will tell you that I’m very interested in fish eating other fish.  My Master’s research was on the feeding habits of spiny dogfish, and I’ve tried to keep up with the literature on shark-related predation ever since.  It turns…

Big Moves Proposed in U.S. Shark Management

It’s been quite the week for sharks and the fisheries that target them.  First, ICCAT managed to disappoint on shark management (largely through the actions of Canada of all places) but finally started following scientific advice on bluefin tuna quotas.  Then, in better news, the…

Misunderstanding and Abusing Ecosystem-based Management

That ever-reliable settler of internet arguments, Wikipedia, defines ecosystem-based management as “an environmental management approach that recognizes the full array of interactions within an ecosystem.”  At heart, this type of management is supposed to keep all the cogs of an ecosystem moving so we can…

Still Swimming

Well, that was an entirely unintentional month off.  Apologies to those checking for regular updates (especially since I hinted they would be coming in the last post… on October 18th).  I won’t dodge the issue: I’ve officially hit the rough part of being a grad…

So That’s Where the Sharks Have Been… UPDATED

Yes, it’s been a while and yes, I do have more Summer of the Shark updates (and yes, this “summer project” has gotten pretty far into autumn).  To get back into the swing of things, here’s a quick post on an interesting sighting I made…

Heartbreaking and Heartwarming Tales of Social Sharks

One of the cooler trends in marine science has been the revelation that advanced social and learning behavior are pretty widespread among marine animals, and not just the domain of marine mammals.  Stereotypically, whales and dolphins are considered the big-brained residents of the ocean, able…

Summer of the Shark: Best Red Drum Survey Ever

In fisheries and marine science you have days that, by any objective standard, should be an amazing day in the field.  You get a ton of samples, the gear (mostly) works as planned, you find out some interesting stuff, and overall have a lot of…

U.S. Atlantic Spiny Dogfish: MSC Certified

After nearly two years of assessments and public comment, the U.S. Atlantic spiny dogfish fishery has officially been certified as Sustainable by the Marine Stewardship Council.  This makes it the second shark or ray fishery ever to get MSC certification, and is the first multi-gear,…

Shark Week 2012 in Review

Before I duck into my annual review of Shark Week, I have a confession to make: I didn’t manage to see all of Shark Week this year.  In my defense, it was because I was participating in an entirely different kind of Shark Week in…
