Didge,
derek may have been meaning this one about 10k from him
http://www.ausnativefish.com.au/
fish a bit more expensive but they do supply in minimum lots of 50.

There is also Sunland Freshwater fish hatchery Boreen Point Sunshine Coast, unfortunately I haven't been able to find a website for them

Yes, Les thats the one I spoke to. He will have Silvers in a fortnight or so, so I will call him then. I'll probably get 50 first off because I want to minimise the risk of 'dead fish' posts.

You don't have to put your dead fish on posts eh? The chooks will like em, or you can keep them in the freezer if you want! It will save you heaps of nails ;)

Derekh,
here is some info I found on silver perch. Sorry if you already know about this stuff - I am just a newbie. It says they will survive at 2 degree celcius. Don't think my shed will get that cold so they should be right. My stocking density will be 1 fish per 16 odd litres...less as the beds flood and drain. Maybe I need more blue barrels?...or maybe more as they mature. I would get IBCs but they wouldnt get though the door of my garden shed.

Troutman,
thanks for the info on the max trout temp. My current little setup gets to up to 28 degrees at the moment so I rekon as summer comes back in Nov07 I would poach trout before they made it to the kitchen!

Nothing wrong with poached trout Didj....

If you bought good sized trout now they'd be ready by poaching time :D

Didge, this is why a good AP tool kit stocks a chain saw:
connect sky hook to shed roof.....run chain saw around base of shed.....raise shed.....insert IBC on shed floor.....lower shed and clean up.....Bob's your uncle :lol:

Hadn't read that particular article from RIRDC, interesting read thanks

LKB,
Chainsaw - check. (actually the shed is not bolted to a slab...it has a floor of 20mm gravel and has weights bolted to it to hold it down (council acceptable method), so all I need is a sky hook). Maybe I'll unbolt the weights and just lift it up...not that unachivable actually (thanks for triggering that idea)...but I cant dig an IBC in as I have a sewerage main running directly under it (I know for sure because council lifted my shed 4 years ago and laid it...memories are flooding back in...if only I had known back then that in 4 years I would want an IBC in the very place that there was a hole big enough to take 2! They filled in their hole and relaid my shed gravel that they had carefully removed and then put my shed back where it was...all because a tree root grew into the old main preventing my toilet from flushing). hmmm

do you know the dimensions of an IBC? (pointless extra info: people who make their own biodiesel also covet the IBC)

I wonder how long SP could sustain at 2 celcius...not long I am guessing.
(I hope to have a minumum of 10, and only for short periods)

Derekh,
do you want to split 50 fingerlings (25 each), or 100 (50 each)?

Didge, difficult to see the water temp dropping to 2c, my small setup (200l) started end of August last year and water temps were 14-16c lowest, that was under a roof.

IBC's are just over metre * metre * metre, external with cage is probably near 1100mm.

I've decided to modify my whole setup and planned to get my new tank up & running before re-stocking otherwise I would have joined you pair (3-5 weeks and counting)
very tempting (colon twisted colon) :twisted: - feel that HSM :shock: buzz coming on

i'm desperately doing many and various jobs about the place - a larger AP system is one, wife's 40th birthday is the other.

Didj, I'm happy to go either way 25 or 50. I can accommodate either quantity. You have my committment to purchase half of what you order. BTW, what suburb are you in ? I may have missed that in previous posts.

RIRDC have some good info. I have downloaded several of their documents relating to drought tolerant industries.

cheers

Welcome Greg, there is a lot of info on the forum but unfortunately not much on Murray cod - this might help tho :lol:

Quote:
In Aquariums

Hatchery bred Murray cod are now readily available in aquarium stores in southern Australia. Murray cod are intelligent fish and make immensively attractive, rewarding and responsive aquarium fish. It is widely agreed by everyone who has kept a Murray cod in an aquarium that they are fish with "real personalities".

Watching one of these predatory native fish ambush a live shrimp or fish can be an awe-inspiring display.

Whilst slow growing overall, Murray cod will grow quickly in their first 3–4 years of life, so large tanks are advisable — a minimum of 4 ft in length, and preferably 5 or 6 ft. Murray cod like having structure they can retreat to, so structure such as sunken timber pieces will be appreciated.

Murray cod experience very cold water temperatures in the wild in winter, so they do not need water heaters. A temperature of 24° C however will enable fast (optimum) growth, which given the large size Murray cod reach, is generally not desirable. Some experienced aquarists use water heaters and a temperature of 24° C to grow Murray cod quickly to a size (15–20 cm) where they can be conveniently fed on feeder fish, fish pieces and other foods, whereupon they gradually turn off and remove the water heater to slow growth rates back to normal levels. Conversely, Murray cod are susceptible to extremely high water temperatures — temperatures above 30° C are not recommended, and temperatures significantly above 30° C will cause death. In heatwave conditions in the summer of 2004/2005 a number of aquarists in Australia suffered unfortunate losses as house and tank temperatures soared far above usual levels. Soft drink bottles filled with water and frozen can be used as an emergency measure to reduce tank temperatures.

Unlike many freshwater fish, Murray cod are highly tolerant of salt due to the raised salinity levels they sometimes experience in the lowland reaches of the Murray-Darling Basin during extreme drought. Indeed, common sea salt is a useful tool for keeping Murray cod in tanks, a salinity of 2 grams per litre improves health and keeps most pathogens ("diseases") at bay. Ensure, however, that the sea salt used is free of additives such as iodine and free flow agent.

Caution, and ideally, quarantine procedures, should be used to ensure that feeder fish do not introduce diseases to the tank. With soft skin, Murray cod can be susceptible to white-spot or "ich" and fungal skin infections. At a minimum, disinfect all live food for 1 hour in a 10 gram per litre salt solution before feeding.

Water pH should be kept neutral or slightly alkaline, a pH between 7.0 and 8.0 is perfectly acceptable, 7.0–7.5 is ideal. A small amount of shell grit will provide a buffer against violent pH swings.

A common complaint voiced about small Murray cod in aquariums is that they "hide all day" and "don't show themselves". This is usually only a problem for the first few months of life. Most Murray cod in aquariums, upon reaching a certain size, suddenly gain confidence and then become inquisitive, responsive and rewarding aquarium fish.

Hi there Greggsie,

Although you get air temperatures down that low, water temperatures will never get to the same temperature unless the air temp stays that low for a number of days 24hrs a day..

Try looking in your local yellow pages to find aquaculture businesses in your area, if you know what others are growing, this will give you a better idea of what you can grow in similar conditions..
