There are also a number of issues with large scale aquaponics, even including e-coli issues.
Ken, How are there ecoli issues with large scale aquaponics when ecoli only comes from mammals and not cold blooded animals like fish?
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

Ken, How are there ecoli issues with large scale aquaponics when ecoli only comes from mammals and not cold blooded animals like fish? The huge spring that provides water to the raceways receives both groundwater and runoff from nearby cattle fields well above the spring, and well away from the spring. The water is run through UV light before entering the raceways, but there is always some present, or the possibility of it being present is always there. If the cut lettuce is accidentally splashed with water, or if some leaves happen to touch the water, they become contaminated and cannot be commercially used.

I do know UV is not always 100 percent depending on the water clarity and how old the bulbs are. So they are utilizing raceways and not jut the large circular tanks for the trout? One thing has me baffled. How the side drain of the Cornell dual drain they use does not regulate the depth of the water as it appears to be below the water's surface of the circular tank. It doesn't seem logical to me.

Cecil, Yes, the water just flows through the raceways, to a large aquaculture greenhouse, through an even larger aquaculture high tunnel, and then through a bio filter bag before going into about a half-acre pond used for growing things like water cress. The water then goes into a creek where it is purer than when it comes out of the spring. If anybody wants to visit sometime, just let me know and we can arrange such a visit. It is always changing, but here is a little info from about 18 months ago. Reymann Farm Ken

I was thinking of the wrong facility then. I was thinking of the Freshwater Institute in Shepardstown. Didn't you do some work there too?

I just get to visit there. For our WV Aqualculture Association conference next week, we get to tour the National Center for Cool and Cold Water Aquaculture, also near Shepherds town. I just get to visit there too. But, we've got some pretty neat aquaculture/agriculture research facilities all around the state.

I am clearly out of my league here, but I think the ecoli issue needs to be clarified
Ecoli is an issue as you mention above because of outside contamination
Fish do not carry ecoli, and therefore this would not be an issue with a closed loop Backyard system, unless ecoli was introduced from another source (ie humans)

forum schedule, lots of good topics for pond bosses, and aquaponics (thread title) http://www.aquaculture.ext.wvu.edu/r/download/148561probly old news, but still time to get there, but alas not me and ken, (how many kens are there in WV?), the posters (i think the wall variety) sound interesting, please include pictures of them with your report The speakers sound interesting too and they are pulling them in from Arkansas and Tennessee. And further down "This presentation will describe the format and principles relevant to conducting aquaponics with profit in mind." ok, last link on WV aquaponics, interesting for me

That's partially mine -- I'm hosting/moderating the pond-related sessions and Dr. Ken Semmens has the producer half. Bob Lusk (Mr. Pond Boss) has graciously agreed to do the opening for my sessions on Friday and Saturday. You can find a little more about it from my previous post - Mid-Atlantic Pond Conference We've still got plenty of room. Come on down. Ken

Wow. That is an old presentation. Those photos are at least 10 years old. It looks a lot different now.

I think Cat and I know that, but it's good you brought it up so others can makes sure they understand that. I think one of the many strong points of Aquaponics if done without any contamination by outside mammal excretion is the lack of ecoli.

I may not have a choice since we appear to be stuck in this drought...all the outdoor ponds are drying up around here.

Join the club. Sadly most of the country is well below normal precip and has been since late spring of last year. Of course I'm sure it's not as bad as you but still not good. We haven't even had much snow precip here.
Sure glad I can top off my ponds with a well. Just hope this doesn't continue for a while or a well may not help.

An idea I had was to use the barn as a fish space and cut out one side and add a solar green house for aquaponics. Use the barn side as a solar generator.
Your pond could be done as a shrimp farm if you design right. Use water from pond for vegetables that can't be done in aquaponics or a nursery.
