The crash of marine fisheries...

It's ironic that I developed a recipe for ahi/big eye tuna the other day.  Today I read about a University of British Colombia study that talks about how Norther hemispheric marine fisheries that have been actively managed have suffered a 90% decline in the past 60 years! I wonder what the ahi/big-eye recipe tastes like when cooked with tilapia?  Something I'll likely try in the future!
