Backyard Aquaponics
A place to discuss aquaponics

Trust me - I have no issue with exposing shysters and informing people there are such. One of the great things about the Internet is how fast information like that can flow.

The biggest issues is probably describing optimal systems that require just about sleeping with the system to produce - compared to a normal system. For example, I see the number of 3 kilos per 100 liters of water kicked about - and it sounds reasonable - others are saying up to 6 kilos. Yeah, I suspect you can if you don't have a day job... In a commercial system with full-time people, it probably makes sense but you better know what to do.

The closer you get to optimal production, the more fragile the system I suspect.

The classic shyster understates the complexity while overstating the productivity.

Ain't that the truth .....

given proper oxygenation , couldnt the plants to fish ratio theoretically be pushed so far ( more than 2:1 GB to tank ratio ) that one could stock fish at huge densities ?

Probably not..... there are other factors to consider other than just oxygenation.....

Flow rates, dissolved Carbon Dioxide etc.....

Eg .... if your ratio was say 4:1..... you'd need a huge sump/reserve tank to supply the growbed volume..... to oxygenate and turn over the sump tank + fish tank..... you'd either need a rocket propelled pump or an oxygen injection system costing thousands.... or both

Then there's the risk of stress to the fish and/or disease factors....

Diminished response times availible to cope with any spikes etc..... it would require monitoring 24/7....

2:1, with experience and knowledge, and a mature system could see you up around 6kg/100ltr perhaps without too much drama.... beyond that... it becomes intensive even for a full blown aquaculture organisation

At higher densities, you have higher effort to manage it, higher risk if something fails, and higher cost for the fancy equipment. It's important to consider what your most expensive (or hardest to get) assets are. If real estate is expensive, labor is cheap, and fancy equipment is not a huge issue, then sure, go for high density. I think for most of us, the real estate is the cheap part (we already have space in the backyard), labor is expensive/hard to get (most of us have day-jobs or children to care for), and fancy equipment is a burden. Lower density makes sense.

This kind of data helps - if you were to say that 3 kilo / 100 liter is good for starters and for those who don't want to work too hard - cool.

Up to 6 kilo / 100 liter - doable for the experienced with a mature system.

Beyond 6 kilos / 100 liter - you are bolding going where you are on your own.

I think we do have one of those. I don't have time to search for it right now, but it rings a bell....

I know that Murray and co started here and that some thing "happened" but is anyone suggesting that all their business activities be put on this list or just some of them.

Remember before you post the posibility of law suits if what you say isn't true (or they think it isn't)

and there are people continuously surfing the net looking for opportunities to sue for defamation. I have been threatened with relation to that developer we had trouble with (she still hasn't paid up and is now claiming she has no money) I know it is buillshit, but we have to be VERY careful what is said. From my understanding of defamation law, even if the statement made is true, if it is made with the intention of causing the other person disrepute, you can be sued for defamation. But I could be wrong, and I know the laws are different in each state. And the internet opens up a whole new kettle of fish.

The number of of law suit threats that have come through this forum would surprise many of you..

Legal threats as well as just abuse... This is part of one that came through just today:

Another happy customer

You can't please everybody heh. I wonder what sort of havoc this type of goose causes in the non virtual world.

i think murray and co are actually not too bad, I don;t think they are aiming to rip anyone off and have actually been quite good in terms of deals done to a few of the people on this forum. They have based their turn key system off of a proven system developed by someone else in a far away foreign country and have bought this technology to australia, I am not overly concerned about this at all, I think a case of buyer beware is especially true in novel industries.
Any way that is my two cents,

The problem with posting that EB is that it opens a can of worms.

For those of us who have been around for a while or less but not a longer while or more something obviously happened.

I've seen some pretty wacky posts (ie aggressive) from people who have arrived on this forum and for the most part I havn't been horrified nor ashamed by most of the responses from the membership.

At another forum I have got a sense that things are not all that they say they are but maybe my perception is coloured by my frequency on this forum.

Nelson came out and said some pretty blunt things the bluntest and lest ambigous being that "the principles of GANRAD don't actually have much experience in aquaponics". I guess relative to her and others that may be true but to many people on this forum it would not be true.

So I ask what else should the AP community beyond this forum be made aware of about the principles and Principles of GANRAD.

I think we've all found a great group of knowledgeable people here , always willing to help . I guess from this point , logic would dictate I ask people HERE , who's posts Ive read and know where theyre coming from , about anyone Ive NOT seen on this forum who I was intending to deal with in regards to aquaponics

ie: if I was to buy fingerlings , I wouldnt start by looking in the yellow pages , nor systems nor equipment . Id be asking people here , rather than hunting stuff outside of this base of "past experience" so I know what Im getting into

but yeah , theres people who will jump in the deep end , with the advice of the wrong people and may give the whole of aquaponics a bad name due to their bad experience . But then again , thats the kiond of person that never does research , always gets burned , and whinges their way through life blaming other people for ripping them off . Kinda like a rabbit whinges when a fox grabs it for being slow and lazy
