I thoroughly enjoyed this presentation on aquaponics since I dabble with it in my backyard (see link), and attended a conference on it in Hawaii.
I especially liked the part the speaker presented on finding the optimal pH requirements that accounts for needs of plants, fish and bacteria. They also present little rules-of-thumb for feeding, planting:fish ratios, and supplementation.
