Here's the slide deck presented at the Mother Earth News Fairs during 2016. There is also a link to the audio recorded in September at Seven Springs, PA.
The slides cover some basics about growing plants, raising fish, and building systems, along with discussion of how (and why) system designs have evolved over time. Finally there is discussion about water footprint, which is an area where aquaponics truly shines.
The audio lasts about 60 minutes and is here.
