Fry Growout tanks - as simple as can be the time to achieve full production. This at least is a known quantifiable that can be modelled. Other known risks include skills shortages (lack of know how), power outages, water supply shortages and to an extent weather variations. These can be modelled and to a greater or lesser extent mitigated. The unknown risks, disease, filter crashes, acts of God, water quality failures and equipment break downs are a lot harder to quantify. The stuff you didn't plan on or sign up for when you started your fish farm in other words. My old mentor in business referred to these things as 'school fees' - you may also refer to them as 'experience'. Experience is often hard learned. For instance, learning that your filter system is in fact not capable of sustaining the claimed load of fish is only going to happen when it collapses, falls over and you lose every single fish in you operation overnight thanks to a crashed filter. Or that expensive drum filter you spent your next two years profits on actually did need some grease on that cog before it stopped rotating and clogged, killing every fish in the system behind it. Or that one hour when your backup power system dropped the ball and stopped the air supply to your system, killing every fish in the system behind it. The Original Grand Daddy. Ten years old and still going strong! You get the picture? It's not pretty and whilst the old saying amongst veteran fish farmers says that any fish farmer worth his salt has killed many crops of fish accidentally you don't need to do it too many times before the expense of starting up again catches up with all the time you have lost in production and forces your bank manager to send your farm off to the auction house and you into insolvency. Don't kill your fish. No matter what, ensure that they survive! Knowing WHAT is important, is something that you will have to learn - and take it from one who has, the slightest short-cut that you take will cost you a thousand times over. Filter systems here are generally the biggest culprit because they are the easiest to bamboozle inexperienced customers with. Write on a label that this filter will process 10 000 litres of water, stick it onto your small black box and hey presto! It's magic! And cheap! The real world doesn't work that way. Your filters on your system SHOULD be the bulk of your expense (in ours for instance it's upwards of 80% of the cost of a FarmInABox pond setup - the ponds and water being the really cheap part of any operation). And they should be 100% of the design. If I could make that figure 110% I would. If that doesn't tell you something, something is wrong and it isn’t going to work! The real trouble is by the time you realise that it isn't going to work your bank manager is the one pointing it out to you. And that, well, that's just awkward! Practical experience I agree cannot be taught, but at least these days we are at a level where there is considerably more knowhow and experience that can be spread around than there was even just ten years ago. Having a p hone number of someone to call for instance is now a reality and tools like FaceTime or Skype can instantly show a problem to the other side. What wouldn't I have given for something like these ten years ago! Risk management of the unknown then becomes mitigated by the application of learning and experience. Disease management is easier to implement with quarantining procedures and a closed farm approach with your own on site hatchery. Equipment failure is not quite as easy but it is not hard to ensure a robust reliable system with good design and redundancy to overcome these. I repeat. If you cut corners your farm will fail. No ifs or buts about it. Please rather send me the money to spend on a nice holiday to a tropical island with expensive drinks
