  1. "Supposedly" is correct. Research has revealed that that commonly held belief is in fact a myth.
  2. A lot better than sheep, too. (IMO, of course.) Boer goats are ideal for meat, but not for milking: For milking its better to go with Saanen, Toggenburgs, Nubians or Alpines. Fencing can be a bit of a problem sometimes - (there's a saying among goat owners that any fence that won't hold water won't hold a goat either) - though if our Boer gets out she always heads straight for the back verandah.
  3. Right on, Ravnis. Crazy forcing ruminants onto a diet that their systems aren't able to absorb as nature designed. No wonder the critters subsequently need a regime of antibiotics to treat the problems caused. The bottom line of course is profit. The same goes with farmed fish, however home aquaponicists generally have the advantage of being able to choose suitable food for the species of fish they are raising, without worrying too much about returning a profit to shareholders. To my mind, even if the cost of raising your own fish in a home AP system was to be about the same as having to buy at retail outlets, you'd come out ahead knowing that your fish are healthy and safe to eat. Deduct the ammount you are saving on garden produce that is likewise fresh, clean and healthy, and you are miles ahead. ......Bid...
  4. Was checking on the same thing myself a while ago and found that Castaway had posted this on the ap.net site: http://www.aquaponics.net.au/hq/viewtopic.php?f=10&t=15&p=19&hilit=Omega+3#p19
  5. Dave, it's extremely difficult to grow out/breed earthworms that you've dug up from the garden as they're not exactly suitable for a worm-farm setup. Try getting a small supply of the Red Wrigglers or Indian Blues that are usually found in compost heaps and you'll probably have a lot more success. ......Bid...
  6. Hi Gary. Check your PMs for another article along the lines of Jean Pain's system. ......Bid...
  7. That's what I like Julie: A completely unbiased opinion.
  8. Dave, I have both the "CUBA - The Accidental Revolution" DVDs, (Agriculture and Medicine), and think that they are real eye openers. The Agriculture DVD in particular, showing what can be achieved without the use of artificial fertilisers, herbicides and pesticides, gives me hope that when Peak Oil is reached and passed, (if it hasn't been already), and the effects finally filter down to the people, there can be a redirection of agriculture that doesn't have to involve the likes of Monsanto, et al.
  9. A Heart-Headed Chookfodder Do I win? What's the prize? Actually, it's a White Crowned Snake (Cacophis harriettae)
  10. Thanks Dave, Some photo's would be great. Bid... (... dashing out to check if one of wife's laundry baskets will fit into one of his 200 litre barrels.)
  11. Thanks for that, MS. I'd not seen it before, but it makes good reading and I've copied the link. One particular item caught my interest: An interesting example is offered by an Eastern European country that was unable, in the late 1970s, to produce rabbits in competition with the Western industrialised world. On the big state farms, each keeping two to five thousand does, productivity was only a little more than half that of the private Western farms. The latter kept, at that time, generally no more than five hundred does. Then, in the East European country, the idea was developed of providing a stock of about ten does and one buck to each rural family up to a total of three hundred thousand families. In this way they obtained over three millions does, this number greatly exceeding anything possible in an industrial unit and even the total number of animals on national industrial farms. The no-cost rural production system was placed in competition with the advanced Western industry. The rabbits were brought to predetermined collection points and sold at relatively low prices on the Western market. This strategy gave a small but constant income to rural families and it provided the country with excellent gains in hard currency through export. But it caused a lot of trouble to the Western rabbit industry until the Eastern state economy collapsed. The collecting system in the rural area ended too, and no private enterprise was able to recover it. Luckily for industrial production, rural production is dispersed, economically feeble and not organised. As the example shows, when it is well organised, it can manifest its tremendous power. A well organised chain of small AP systems could similarly be of tremendous benefit to their individual operators and to the community as a whole. (Multinational agribusiness probably wouldn't be too thrilled with the concept though. ) ......Bid...
  12. Dave, could you post some details on the construction of your swirl filter? I'd appreciate it. Thanks, ......Bid...
  13. Absolutely, Gary, although it makes a great beat-up for the media. When you consider the population of China Vs the number of problems they have had, proportionately they are probably no worse than what sometimes happens down here or in the U.S. (where they are having enormous problems with e.coli and the like. The Chinese people aren't too thrilled with their own companies that cause these problems either, and their punishment for transgressors, (who can't always bribe their way out of trouble), tend to be very severe - at times to the point of being terminal. ......Bid...
  14. Randy, with the type of flush valve pictured, after the float has risen with the flood and pulled the flapper open, wont it sink with the draining water and allow the flapper to close before the grow-bed is fully drained? (I've not seen a valve of the type shown so I'm not sure how it operates.) BTW, I think your original design reflected some original thinking. Should be good for small systems, but I don't think that you'd get sufficient venturi effect to pull enough air out of a large syphon to get it flowing.
