Ageing Spiny Dogfish: Are We Doing it Wrong?

Welcome to the first post in 2012.  It’s probably good to start the new year off with a doozy, and in keeping with the theme of this blog, it involves that scrappy little shark everyone loves to hate.  Spiny dogfish are possibly the most well-studied…

Who’s Eating Atlantic Salmon?
