    I don't have experience with trout in AP. We actually were going to get some this year but I talked with the state head for fisheries and he stated that they were extremely hard to keep alive in a closed loop system. They are not hardy fish and even the state labs have a hard time with them in their systems. I hope that helps a bit...other than that all I can tell you is they need very high DO and low water temps.

    there is no problems raising trout in aquaponics or (closed loop system)
    some basic guidlines
    watch your stocking levels best water temps under 19c
    lots of air
    a filter, radial or swirl may be necessary
    in southern aussie our ideal range for growing out trout is march
    to november in northern aussie a bit harder with higher yearly mean temps makes
    it to hard grow out
    a couple of pics of my trout harvest started from 50mm -75mm fingerlings in 8-9 months
    trout are the quickest fish i have used to get to plate size, and your vegies go ballistic

    That fisheries guy needs re-educating, or sacking!

    Trout are a wonderful fish for growing in aquaponics, many thousands of people do it very successfully every year. As Silloth has suggested, the seasons are the limiting factor. Here in Oz our Rainbow Trout are okay at water temps below 22C, but prefer it under 20C.

    Where I am in Perth the water normally gets down to suitable Trout temps by mid Autumn, around mid April to early May. They are then harvested in late Spring when the water temp increases and causes them to go off their feed, usually late October, early November. People in the SE, Melbourne, Canberra etc, get a slightly extended season compared to Perth.

    The three keys to keeping Trout would be;

    1. Water temps below 20C
    2. Clean water
    3. Lots of aeration

    Last season in only six months, in a very basic IBC system, ie GB over FT and no extra filtration (other than the GB) I got Rainbow Trout from fingerlings to 600+ grams gutted and gilled, with an average of around 500gm. They are very easy.

    Thanks for the info! I am still very interested in growing trout and will put some more serious thought into them again.

    Thanks for the info Yabbies. I too would like to use Rainbow or Brown Trout here in Victoria (-20 Water no problem). I was of the understanding that Trout need moving water and therefore are really not suited to Dams, Tanks etc. Quality aeration would fix this issue as you mention.

    We are probably going to have to look to trout once November comes because our FT is 40,000L and in direct contact with the ground. So there's not chance of keeping it too warm. I've read that Rainbow can be a bit sensitive to PH etc but I think that might just be rumours. They are from the mountains of BC and the PH can vary from stream to stream.

    I am looking at using trout in my future system too. I found the following doc n the web - it's quite detailed and is all about aquaculture. I haven't fully read through it yet, but looks like a good starting point.

    Thank you for the information! My wife and I are working to establish an aquaponics system by mixing an already existing trout tank (200 m3) with a nearby greenhouse (400 m2). The property is located close to the mountains of Chihuahua, the elevation is high (2000 m) and it is cold most of the year (average 10 C). Trout like cold water and the property has plenty of it. The greenhouse is used to grow tomatoes, I am concerned about the temperature because tomatoes likes to be warm and trout cold. Any suggestions to solve the water temperature problem?

    i had my trout at 26 degrees the other day and they lived thru (they tend to not eat above 22 degrees tho). if you can use a solar heater to warm the water a bit trout are fine at around 16 - 20 (i found they fed better)

    What a timely thread!

    I was going to search for similar topic as I'm sure there is plenty of info around.

    My problem is also the weather. We're in Canberra and about to take delivery of a 'Black beauty system.

    Due to the weather variations here, April thru Sept can see - 10 degrees.

    Oct-Nov then tricks you with a few 30 degree days and gets cold again. We've had snow at the start of December although that is fairly rare.

    Dec/Jan we usually get up to around 40 then Feb/March it starts to cool.

    Wondering if we will need to heat the water a little in winter, cool it for summer (with summer obviously the clear issue)...

    Hello everyone,
    I am running an aquaponics with trout and with a local river prawn. We started on november 2012 at Elqui Valley near Coquimbo city.
    Our wáter temperature in Winter is 8C and in summer is 22C with shadow...w/o shadow wáter goes up to 28C. We are producing about 6 MT/year of trout and 1600 / veggies per week.
    Cheers

    Yep...I am at Chile...about 500 km north Santiago.
    Last month I have visiting my farm Dr Rakocy, Dr Kevin Fitzsimons, Dr Raul Piedrahita and some more people due to a V Aquaponic Conference which was held at Coquimbo organized by Carlos Leom from Bofish Mexico.

    I might say is close to comercial if we speak for aquaponic level. I have 8 cylindrical tanks (each 20 m3) and 16 hydroponic raceways (15 m3 each). We are able at the moment to sell 500 kg trout/month and 1600 veggies/week. We do lettuces, celery, bassil, water crest.
    Recently we include melon and tomatoes.

    @German: I would be very interested in some photos of your setup? It sounds impressive!
    I looking to build a much, much smaller system...but I'm looking at running rainbow trout at fingerling stage. I'm in Melbourne, Australia.

    Michael,
    You can see some pictures at www.acuiponia.cl and some reading. Spanish though.
    I will try to upload pictures any time.
