Backyard Aquaponics
A place to discuss aquaponics

I though it was a good idea too Aquagold


Silver Perch.

The optimum temperature range for commercial production is 23-28° C.
Min Temp ~2 Deg c, Max Temp very low 30's.
Silver perch can be raised to market size of 600-800g in around 8 months.

Rainbow Trout.
Optimal temperature for rainbow trout is 12°C
Rainbow trout will be found between 6°C (44°F) and 23°C (75°F).


Barramundi.

Best temperature range between 25-27oC.
Still feed from 20 deg c up. (VB)


Murray Cod.

Specimens regularly reach ages of 30-35 years.




I will add more and update this post as I find more

Anyone got any more?

if trout were ok up to 23o would definitely have enough time
thanks OBO, now where to find them

Some of the temp ranges often quoted are pretty silly IMHO. I realise they are 'optimal', but one should be a bit more realistic I reckon. In my experience, Barra feed ferociously at 22 or even 20 degrees.

Thats what this topic is for VB - Real world experiences.

Cod Fish, best i can come up with is http://www.aquaponics.net.au/webcontent4.htm
sorry

And that info's about two years out of date

Yep... you need to remember... most of that info relates to pond based aquaculture systems.... not necessarily recirc tanks and definitely not AP....

Also based on data almost exclusively from Qld and Northern NSW....

18 months to grow a Silver Perch to 600 - 800 gms..... depends where you are, how you grow, heating etc...

Again pond base data.... may apply to some AP people who have looow overnite winter temps...
