    Default Aquaponics

    Has anyone here tried aquaponics at home?
    I am currently in the process of building my first system at the moment.
    For those who dont know what aquaponics is, it is similar to hydroponics where plants are grown without soil in a medium (like clay pebbles or crushed rock)fed by nutrient rich water. Hydroponics are grown using chemicals to provide nutrients however with aquaponics you use a suitably sized fish pond/tank to provide the nutrient. in return the plants provide the fish filtered water.
    My fish tank is around 800/900 litres and i intend on stocking it with approxiamately 80 silver perch fingerlings. This will be pumped through a flood and drain bed of vegetables and also constantly trickled through a secondary system.
    In the end i should have more vegetables than i alone could possibly consume (lucky for friends) and in approx 8 months or so 80 edible fish.

    I will upload some pics once system is complete.

    I think one of the guys on Gardening Australia is doing it.

    I'm not sure I pay enough attention to my garden as it is - to keep fish going as well. But it seems like a neat idea.

    I'd like a worm farm but I'm worried that it will get killed by our runs of 40'C+ days

    Very interesting Peter. I love my aquariums and stuff like that. Cant wait for the pics.
    Curious as to why you chose silver perch and what will they be eating. I used to have 2 very large Barramundi in a tank and everyone said i should eat them. Yuk !! Pellet and live fed fish sounds terrible to me, i dont even like pro farmed Barra compared to wild fish but i am spoilt for choice up here as we always have reef fish in the freezer.

    Hey Sean I chose the silver perch for thier hardiness, ability to live in colder climates and thier eating qualities, yes they will be eaten. Feed will be pellets and worms etc.
    The beauty with this setup hyacinth is once the initial setup is done it can be used over and over, also once running it basically requires maintaining water and feeding fish.
    Will put up some pics on weekend with where I'm at.

    looks awesome. I'd love to do something like that if I had the time to actually put everything together and look after it. How does the water flow through in your system? Aside from feeding the fish, is there anything you have to add to the water to boost nutrients for the plants or to make the water better for the fish?

    I'm curious about the size of the tank that holds the fish. Depending on the numbers things like deformed fins, gills etc and diseases can be a problem. In saying that i'm thinking along the lines of aquarriums and dont know anything about this type of set up. Love to hear a update on how it's going Pete.

    aquaponics is based on moving water to a degree, but just like an aquarium once the bio life is set up there should be no disease as the plants are filtering the water for you. Stocking rates will always be a standard but some species can get away with higher stocking rates, hence why being so popular for aquaponics (barramundi, perch, brown trout)

    Hi guys seen as though theres some interest i thought id give you an update an explain system.
    Im currently using around 20 or so goldfish, was originally going to use silver brim however supplies were unavailable. So far no dramas other than two fish sucked into the garden bed, sorted with a filter.
    The only maintenance required is a top up of water and because i use sump/washing machine i only need top this up when low. On average this has been around 20 litres a week, not bad usage considering im growing vegies. Of course i feed fish however this is relatively a low amount as i still get mosquito larvae etc in water.
    At present in the main beds i have broccoli, celery, various lettuces, beans and soon snow peas.
    In the Pvc i have lettuces, strawberries, parsley, corriander and thyme.
    So far have only lost a couple of plants mainly around the time they are laying roots in medium.
