I kept Aussie yabbies in a heated tank.
When you vary the temp up and down it simulates their natural breeding pattern back home and they mate...
But boy oh boy when they're born boy do you need a big pond...
theres thousands of babies.
good eating too.
Bush tucker man Les Hiddins love em.

There was a show called home of the future and they had an aquaponics greenhouse with fish.
here is the site http://aquaponics.myshopify.com/collecti...te-systems
Although it is a bit expensive, it looks awesome.

from my own research carp is best as they can survive in 4C, which should work in winter without needing to heat the water but you might need to heat the greenhouse somehow or bring them indoors

Thanks SP, your findings match my own I used to breed Carp, Koi and Goldfish and found that if left outdoors over winter they really needed a pond set at least 5 ft deep into the ground for the fish to survive it stopped the fish from suffering tissue damage, I ended keeping mine in insulated water tanks in the garage.

Seen what you can do with just common cyprinids like goldfish and carp if you give em a big enough pond to grow in. Carp grow to match the size of their domains, thats why goldfish kept in bowls and small tanks only grow a few inches, they release a hormone into the water that prevents them from growing to big. BUT put carp / goldfish / koi / mirror etc into a large pond and watch em grow.

Iv got Tilapi in a 4 ft fish tank in the kitchen at the moment.
They are going into an Aquaponics system later this year.
Tilapia are the third largest farmed fish behind salmon and tuna world wide.
Yes they need to be kept in heated water as they are tropical fish but the plan is to build a rocket stove mass heater to heat the water.
The water acts as the thermal mass and the tank and grow beds are insulated.
Its my project for this Autumn.

I'm told they hope to gow Tilapia on a commercial scale at the new Eco village up Westgate in Weardale if the village goes ahead, apparently they found some geothermal water sources to tap into.
