Hydroponic Octopus Farming? My UIUC Student’s Project


I teach an undergraduate course in our Campus Honors Program. Today, I had coffee with a sophomore from a farm in southern Illinois.
He’s the team leader for a UIUC agricultural marketing project that is looking into hydroponic octopi farming.
Some background: A UIUC team of professors and students in the 1980s helped to develop hydroponic tilapia. 
For mature blog readers, you might recall that tilapia was not on the regular menu back in the 1980s. 
Most of our tilapia are “farmed.” They are grown hydroponically. The waste from the fish is circulated as fertilizer nearby for hydroponic tomatoes and lettuce. It’s sustainable, profitable, and doable on a small piece of land.
My student and his team have discovered that demand for octopi has grown by over 600% since 1990. Supply has become a problem. The biggest octopus fishery in the world has collapsed.
Showing my ignorance, I volunteered: “I assume that is China.”
“No, professor, the largest octopi fishery was off the coasts of Morocco and Spain.”
It turns out that octopus is not only an Asian food—it is a staple in several Mediterranean diets.

My student says that a profitable octopus farm can be put on a one-acre plot of land, right here in Illinois (or anywhere else with good water supply). Waste runoff? Negligible. Put your farm 40 miles from Chicago, St. Louis, or Indy and you've got good markets for your product.
Like tilapia, octopus farming can be integrated with hydroponic vegetable farming.
Here’s wishing the UIUC Ag Marketing Team great success in national competition. We’re all winners when our students are pushing the boundaries of innovation.
