Effects of Biofilter/Culture Tank Volume Ratios onProductivity of a Recirculating Fish/Vegetable Co-Culture System

M. R. McMurtry, D. C. Sanders, J. D. Cure & R. G. Hodson This paper documents a year-long greenhouse experiment designed to answer a simple question: can iAVs remove nutrients from water and maintain stable…

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…

A Case Study into an iAVs Nematode Infestation: What they did wrong, and how to do it the right way

A Case Study into an iAVs Nematode Infestation: What they did wrong, and how to do it the right way

Why Serious Growers Use Compartmented Systems it is considered better practice—especially for commercial growers – to utilize multiple, smaller compartmentalized systems (modules) rather than fewer, massive monolithic systems. This approach is grounded in risk mitigation,…

Sandponics is NOT iAVs

Sandponics is NOT iAVs

tl;dr;  iAVs (Integrated AquaVegeculture System) is NOT “Sandponics.” iAVs is an open-source, scientifically validated system using fish waste as the sole nutrient source for plants grown in sand, which also acts as a highly efficient biofilter. This…

This is a guide for a standard ‘on-ground’ iAVs build with a 2000L biofilter (growbed) and a 1000L fish tank. … stay tuned for more updates!

Elevating Aquaponics to a Validated Science

Elevating Aquaponics to a Validated Science

This is an excerpt from the iAVs Handbook. Aquaponics, the integration of aquaculture (fish farming) and hydroponics (soilless plant cultivation), is a field attracting considerable interest. While the term’s use in peer-reviewed literature has markedly…
