Here's a link to some folks who sell pretty small (more difficult) setups but at great prices.  I might email them about a slightly bigger set up.

Native Fish Aquaponics

Oh, and don't be tempted to add crayfish to your pond that has fish.  It will end very badly. (This info comes from a big mistake I did in my tropical tank.)

It depends on the fish Jodie.  If you grow bara - you'd have to seperate babies (they'll eat anything that fits in their mouths!).  Bara grow at consistent rates.  Perch are a much more social fish and they grow at different rates. They don't eat the littlies and so you have a more contineous "crop."  Bara will grow to plate size in 12 months.  I think perch are a bit slower but not a lot.  Both fish are suitable for our area and both are pretty hardy.  

I was going to use the cheap commercial food. However, you need to make sure the food has no land animal in it.  I know it's not completely closed loop but it's easy.  Perch will eat vege mass which is pretty handy and in theory you could grow some vege mass to supplement the food. (This info comes from a Murry Halam talk.)

There was or maybe still is, some posts and photos on a Soldier Fly breeding system. Just tried a search now and didn't find it but it might be worth a whirl to have another look. There will be a stack of YouTube videos on breeding them.

I don't think there is such a thing as a cheap/free aquaponics system.  Your time is never really 'free'. You can buy half barrels and half blue-plastic storage tubs fairly inexpensively.  Ultimately tho, wouldn't you need several tanks, perhaps of various sizes, so you can grow the babies separate to the adults?  Even our goldfish eat the baby fish in our household tank.  Otherwise you've only got an annual or bi-annual harvest (how long does it take for a perch to grow?).  You'd perhaps even need a third tank to grow fish food, so it's not as simple a system as at first concept.

I have heard about creating maggot factories for feeding fish and poultry - again, simple in principal but yet another complicating factor if a closed system is the goal.

I was looking at these for a tank:

It would need a lid but I suspect some roll up black plastic would do. The black plastic trough in 1000 litre is about $272.

The thing about your tank is that you want the surface area to be greater than the deapth - that's what helps with oxygen levels.  Bubblers don't actually add much oxygen in themselves - what they really do is break the surface tension and that lets the air into the water.

Not venturing into this myself at this house at least - maybe the next! Very interested to see what information comes up in discussion though to "prep" myself.

Comment by Andrew Cumberland on January 11, 2013 at 23:30

LOL. I can't eat the suckers because I'm alergic.  But, not to those shiney perch that are going in my aquaponics set-up!

As well as the outdoor setup I'm thinking about, I'm tyring to work out a way to use the water heading into my filter on my 4 foot tank to grow some indoor veges.  Trick one - how to make it REALLY pretty?  Trick two - it should work as a bonus second filter for my tropicals!

The Redclaw in the picture is one that I grew at home.  His name was Legoless (named after the Elf in Lord of the Rings - different spelling due to the fact that I got him for 50 cents because he had no limbs - they throw them when frightened).  I'll put up some links soon that are for places that I think could be useful in "newbie" quests.  (Since that's what I shall be!)
