I have grown those fish from 5 cm's to over 200 cm's in just under 7 months, with a few bigger and a few smaller, and they have done a lot of poo for the plants. For my first system, I am really pleased with how it has gone, and am now looking forward to eating them.

on the temperature thing, I have turned the system off tonight will monitor temp and water parameters in the morning and see how it goes.

u mean 20 cms mon

I imagine that now, you can imagine that you could, with the benefit of hindsight, and a "mature" system, fatten then up quicker and get them to 350-400gms... But yes, your always fighting nature, and that requires effort......

Hey I've eaten plenty of 20cm herring in my time....

20 cm's LOL

Yep Joel, the feeding was almost zero for the first 6 weeks or so. If it was the start of summer now, with all the bacteria established etc, I have no doubt a batch could be grown out successfully in 6 months

Stu,
followed your barra experiment from the start, learnt a lot from the [s]mistakes[/s]controlled modifications and am with you in your achievements

well done, you have 'ed the

Thanks Les.

Funny I don't recall any mistakes, a panic or two but no mistakes. Well done Stu!
Tell me you did not eat the tail!

there were more learning curves than mistakes I reckon. A mistake is only a cock-up that you don't learn from IMHO.
And no, I didn't eat the tail LOL

is that better GF

Don't worry Les, you just had a senior's moment

Good job Monya!

My stepson and I have been watching the Norwegian cooking show by chance on Saturdays, and the guy said last time that lemon juice or vinegar are good to add to fish cooking (he was boiling some) because the vinegar or lemon juice will neutralize the chemical that causes the bad fishy taste. I always thought lemon juice was just to bring out the flavor, but I guess it is to lessen any bad flavors?

Lemon is about the only thing I always add to fish. Generally I fillet them, but when they are this small, cooking them whole makes much better value out of them, virtually no wastage. Generally, I dust with flour, dip in milk, then fry in a bit of oil. When I cook whole, I just throw em in with some butter and maybe a sprinkle of lemon myrtle.

Lemon is about the only thing I add to fish.....after the good woman has cooked it....."virtually no wastage" after I have finished with the plate

I just wanted to make a quick note on adaptability of fish. Recently I accidentally bought 30 kg's of floating instead of sinking pellets. My barra got the sulks BIG TIME and refused to eat them, I ended up having to scoop them out with a net. Witin 2 days, they LOVE the pellets, hit them hard on the surface, very exciting, and I really enjoy feed time alot more now. I also have a new way of losing water from the system, getting it flicked out by barra tails LOL

Mon I recon floating pellets are the way to go as its much easier to know when the fish have had enough and like you say more enjoyable for the feeder to watch.
How those water temps going?? Its got down to 2 degrees (air temps) here the last couple of mornings so the cool weather is on its way.
