This PDF is a straight aggregation of source material pulled verbatim from the first eleven pages of a Google search for “aquaponics history + McMurtry,” with no filtering, curation, or editorial selection. It contains excerpts from academic papers, university theses, government toolkits, textbooks, review articles, educational websites, and industry explainers, all independently describing the origins of modern aquaponics.
Taken together, the material consistently documents that modern closed-loop aquaponics emerged in the late 1970s–1980s through research at North Carolina State University led by Dr. Mark McMurtry with Prof. Doug Sanders and that this system was explicitly named the Integrated Aqua-Vegeculture System (iAVs).
This document demonstrates, without argument or interpretation, that iAVs predates later raft, DWC, and media-bed systems and forms the technical and conceptual foundation of the aquaponics industry as it exists today, based solely on repeated, independent statements across decades of unrelated sources.
This document is to preserve accuracy, prevent ongoing misattribution, and ensure that all 45 members of the original iAVs research group receive the recognition they earned through their work.

iAVs is not hydroponics. Initial ‘experiments’ began in 1983 and first formal research in 1985. NAI was hydro (no media) but was also not recirculating with no filtration whatsoever. Floating lettuce basically failed to yield because the fish ate the plant roots. Very small scale with no replication or attempts to modify/improve. UVI used this hydro/raft approach but separated the plant/raft tanks from the fish tanks and added multiple stage (complex, expensive) filtration (then threw away 95+% of ‘fish waste’ into a sludge lagoon (oh! the aroma!). UVI also never replicated any aspect (could never be peer review published) as well as made numerous provably false claims. Obviously, I could expand – detail extensively – but why bother or ruin my morning?
