@aquacultureAU Hi there mate I'm an aussie too and back in 2005 I completed certificate 2 and 3 of aquaculture
studies at a west australian tafe college We did most of our hands on studies with rainbow trout from the Pemberton Hatchery in fact. I have 6 aquariums all fresh water but only the marron tank is used for my veges so far as I am yet to find a way of using the tanks water without having to cart buckets of water back and forth.
I will follow your grow for sure mate and good luck
