Backyard Aquaponics
A place to discuss aquaponics

By my count there are three commercial AP ventures in southeastern Wisconsin, including Growing Power. At the grocery store last night I noticed the root-on lettuce wasn't from the regional hydroponic tomato grower. Turns out a dairy farm in Baldwin Wisconsin, West Central Wisconsin near Minneapolis Minnesota, is using the methane from their anaerobic cow manure digester to power a 27,000 square foot (2,500 square meters) aquaponics greenhouse. They are using Tilapia instead of yellow perch and growing lettuce and herbs. Yellow perch are the preferred fish of the SE WI ventures. Unlike the non-Growing Power ventures, this one may actually succeed. Instead of dreamers with no experience it's being run by actual farmers.

Here's the link to their website. I only found a couple mentions of aquaponics. They appear to care less about aquaponics then green marketing.

Nice website, no pics of tilapia tanks. Impressively huge greenhouse.

I saw some other youtube video which had a cattle farm that had an anaerobic digester to produce methane which they were selling to the gas grid. Quite an intriguing concept, bio-gas!

and a byproduct of the methane production is hydrogen

And a waste product of hydrogen consumption is water.
Fish are said to like water!
