Fish Species suitable for Aquaponics. |
I live in the Southern Highlands of NSW, where it is very cold, even
now in spring. Is there a fish species better suited to this climate,
or doesn't it matter ? ....Helmut.
Murray Cod would be well suited
to your conditions and an excellent eating fish as well. Silver or
Golden perch would also be very good. A lot of Aquaponic people
have/are growing out Silver perch with very good results. They are a
very hardy species and grow out quickly reaching plate size in just
under 12 months in ideal conditions.
Most hatcheries sell Silver Perch in small lots (50 or 100) for
around $1.00 to $1.50 per fingerling depending on quantity, plus
freight.
I am personally
growing out Jade Perch, but they need to be kept in temps of,
ideally 20 to 23 degrees, so it is possible to grow them out
anywhere really , it just means that you would need to have your
fish tank heated during winter, for Jade Perch, that is.
Silver Perch are not so temperature sensitive.
Barramundi are
really not suitable for colder climates. It is possible to use
Barramundi , but management of temps and disease can become a bit
tricky with Barra in cold climates. It is best to leave Barramundi
until you have gained a lot of experience in fish raising |
Grow Beds and Gravel used in Grow
Beds. |
What sort of gravel/medium should I use in my setup. I have
heard of all sort of things from well meaning friends ?
..Edward.
I
am using 20mm
drainage gravel because it is easily obtained from landscape places
here in SE Qld. 20 or 25 mm river gravel would be better, because it
looks nicer and is a little easier on your hands when planting
seedlings etc. Don't be tempted to go smaller than 20mm gravel as
finer gravels have clogging problems. My first little system used
25mm river gravel and it worked fine.
How deep should the
grow bed be ? ..Graham
Grow Beds
should be 300mm deep. This depth is needed for the bacteria to
establish properly. Shallow grow beds such as trays and
troughs commonly used in Hydroponics are just not suitable for this
reason. Also the 300mm depth gives a good depth of gravel for
removal of solids such as fish waste.
What can I get to use
as Grow Beds ? .. Graham
Grow Beds can be
made from recycled bath tubs. These are ideal if you are on a
budget and have an eye for recycling. If you want to purchase
new Grow Beds then see our site

Solar Powered Pumps |
Hi I am setting up my own Aquaponic setup and was wondering if I
could use a 24 hour continuous solar pond pump that has a flow rate
of 400 litres an hour and would this be enough to keep my plants
happy ??... Edward
I have been using small
500 lph 12 volt pumps run off batteries for my first system, yes it
will work (the solar pump you are looking at) but the system will be
very small.
It is good to start with a small system and learn.
My first system was based on a 200 litre fish tank and some
strawberry towers. It all worked very well, eventually. I had some
disasters along the way killing a number of fish etc. It was a great
learning process.
I think the idea you have to go solar is very inviting but in the
long term it is not able to sustain a large system unless you are
prepared to spend a lot of money on big solar panels and larger
capacity pumps.
But it is a good place to start with a small low cost system and
grow from there.
