Hi Guys and Gals,

Just a quick consensus on keeping rainbow trout with yabbies, specifically, any dangers i should be concerned in regards to damaging the fish?

Tank depth is 1000mm/400ltrs

The trout are no smaller that 5" and the brochure from Aquablue indicates the yabbies would be 7-10cm.

Secondly, my pump outlet pipe is 20mm, and the aquabridge's are 40mm pipe, would they still be likely to climb those Diameter pipe?

((Come to think of it, i will have to look at stopping the blighters from climbing back into the filter from the fish tanks without inhibiting flow. ))

Thanks guys, i look forward to hearing from you

regards
Jeff

Big yabbies will probably nip the tails of small trout fingerlings...

Anything bigger than small trout fingerlings... will eat the yabbies....

P.S... why are you buying, and shipping yabbies from NSW...

P.P.S.... why are you stocking trout through summer.... can you garantee your tank temps wont exceed 22-24 degrees...???

1000mm deap and only 400 litres? Should that be 4000 litres or is the tank very narrow?

Not sure what summer is like in Gisborne, but with the volume of water in my system somewhere near 6500 litres (5000 litre fish tank, 1000 litres of sump, plus 1500 litres of flood and drain growbeds) I cant keep my system below 24 degrees over summer.

24 is pretty much lethal for trout... anything above 20.. and they'll pretty much go off the feed.. and begin to stress....

So if you can't keep your tank below 20 degrees... and a small... and/or shallow tank makes that even harder.... then trout should be avoided...

G'Day Rupert,

Long time, hows things?

Thanks for the heads up, i appreciate it.

As for ordering interstate, i have a broken knee, as such as rarely get out of the house, if i can find someone to send it to me, i do that.
I am not really concerned what state it comes from. Service and quality are the issues for me.
Aquablue provides both of those.
Do you have a recommendation for a Vic based mob?

Summer? we haven't had a summer here in 4 years. So cold and so much rain, my system and greenhouse sank into the mud, but that's another story.

Hi Arbe,
hows things?
400ltrs is right, yep narrow as they go, but nice and deep, i was working in it the other day shoulder deep getting rid of the goldfish and the water was painfully cold.

Regards
Jeff

beauty mate, consider it noted. Even the day temps here don't get much past that, but i appreciate the info.

Gisborne would ne very similar to Lancefield climate. If not the same.
The last few years we have had weather that would permit small numbers of trout to survive since our over night temps get low enough to keep water temps down. Keep an eye on the over night temps. If we get a summer like 4 years ago you'll be having fish soup.!

Mantis might be able to supply you with yabbies
