Backyard Aquaponics
A place to discuss aquaponics

i would just like to thank UAM. It was very nice to meet you and hear about your very diverse business venture. i am sure it will be a great success, especially with people eager to contribute like your associates, purrsikat and myself. i look forward to watching (and helping where i can) this project grow.

and no, no pictures of my ugly mug, this time!

Hear hear! ( minus comment about the ugly mug )

aw shucks thanks purrsikat.

question, how many plants will a 9inch murray cod suppurt using a small NFT
system? i have put two scrawny basil plants in the system today.

depends how much you feed him!

Sorry Pah, no ones gone to that level yet................although i reckon les would be up to such a challenge

yes i know its very small scale but from small beginnings......

i feed him 3 blocks of frozen bloodworms a day.

....still trying to get SP to edible size

Pah, was not referring to smallness with "level" mean "to that level of accuracy" re: fish/plant ratios

ahhhh! now i understand.

i will take the approach of one or two plants at a time till they start to suffer.

still haven't got a nitrate test, will have to wait a couple of weeks for that.

another question, using a bathtub for a pond, what sort and how many fish should i put in it, and how many bathtub grow beds would that support?

using the figures that we go by, 2 bathtub growbeds per 1 bathtub fish tank.

I've never measured a bathtub volume, but i expect it to be betwee 200 and 300 liters, so that would give you a max stocking density of between 12 and 18 kgs of fish.

watch the water temps though, it will get cold during winter with only 200 ltrs.

yes, it gets very cold in canberra with lots of frosts, its actually pouring rain right now.

i am considering trout because of the cold, does any one have any advice on trout.

id suggest going for the trout, just watch water quality, they're ot meant to be as hardy as SP.

I'm getting a batch for dad soon for the winter

just reading the trout thread under fish now.

It seems trout is in the air at the moment... I am also pondering getting some small trout fry and growing them out. But only if I know for sure the big system will be in place on schedule...

How long do trout take to grow out though? It gets hot in Canberra in Summer. From memory they've got a low tolerance to water temps. Don't want 'em dying half way grown....

my thinking is to buy them 5 or 6 inches in size ASAP, then grow them to plate size for christmas before it gets to hot.
