How tough is this aquaponics gig - be honest now!

I'm hoping people who have a set up or two join in to this conversation.  It's aimed at helping those thinking about aquaponics. So how hard is it?  Do you have to be a chemist?  Genius?  Farmer? Fish keeper? Share your experience. Continue

Backyard Aquaponics on Sale ...

Not sure how to view this guy: a fast-talking fear-mongering salesman. I bear in mind the saying: "if it sounds too good to be true, it probably is".I'd love some members of this group to listen to this guy and see what you think about it.…Continue

Aquaponics vs Hydroponics (Kratky non-circulating).

Started by Andrew Cumberland. Last reply by Andrew Cumberland Feb 14. 5 Replies

I've been conducting a comparison of a Kratky hydroponics system vs my traditional aquaponics.  I'll share the links below (two of these are repeat posts but I wanted to show the whole story - the rest will be new).  Continue

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!)

We went craybobbing one day using roo meat (hunted earlier) on string, attached to a twig. Pulled out the redclaw a d the spiny red hissing one from the same creek on a friend's property. Had so much fun.

They crays were put in our 6ft fish tank. I was surprised how easily the red claw bred. The feisty spiny hisser kept climbing out if the tank by way if the silicon sealing the tanks seams. Scared the bejebus out of my brother who was met by a hissing back arched cray just outside his bedroom door.

Both were beautiful eating.

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!

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.

I'm looking for a budget way to do aquaponics.

Comment by Becky on January 12, 2013 at 9:39
Karen, I'm looking for budget ways too. Personally I like the IBCs (intermediate Bulk Containers), the caged one with the plastic tote in it. The prices are ridiculous in these and can range from about $60-$130 used.

If you want free, gumtree and other places giveaway bathtubs. Tubs in lieu of IBC.

Gravel in lieu of clay balls.

Plants from anyone here to give away. Get cuttings from friends/family, even place WANTED post advertise on Freecycle.

Check out plumbing places for pipe off cuts or check out demolition yards. Figure out what system you want whether it is bell siphon or make your own.

Pumps are given away from time to to time in Gumtree or Freecycle. Or pist a WANTED advert.

That's all I can think off as I rush off to tend to a little home emergency.

I was looking at these for a tank:  http://rapidplas.com.au/products/round-troughs-36.cfm

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.

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.

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.

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.)
