Aquaponic Gardening

A Community and Forum For Aquaponic Gardeners

I am thinking of starting a small farm and trying to focus on making a sustainable ecological system.  Need some holes poked in my plan before they poke through my wallet:)

http://www.prairieswine.com/pdf/3418.pdf  A french study where they used three equal sized ponds/raceways to treat/use Swine manure.  First Algal raceways then daphnia ponds and finally the fish pond.  Was thinking basically the same system with a few tweaks.

First an array of salchicha biodigesters.  An array of them to prevent contamination- so i know the effluent will be safe.

Effluent to Algae, solids to black soldier fly's/ worms

 

For the Algae probably a closed photoreactor instead of the raceways, again to prevent contamination.  Maybe like this http://images.thecarconnection.com/med/wastewater-biofuel-algae-cir...  or this https://www.youtube.com/watch?v=Cvi_70sZV-c

 

For the Daphnia, possibly something like a stacked shrimp raceway but shallower.  Looking for something that will be easy and gentle to harvest. http://www.popsci.com/science/article/2011-09/new-shrimp-farming-te...

Looking at raising Sacramento perch in an aquaponic system.  They are native to my area so I am hoping it will be easier to provide ideal conditions.  I am sure the fry will eat the Daphnia, not so sure as they get older.  Was thinking of also growing mosquito fish on the daphnia as a live feed for the older Sac perch.

Here is a study saying Barramundi's growth improved on them.  http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2109.2010.02595.x...

Daphnia are used to clean water in waste treatment plants, does the biodgester-algae-daphnia provide enough pathogen break or should I dry the algae first, Ive read this reduces the nutrient content.

Any thoughts would be much appreciated.
