Dr Wilson Lennard on Commercial Aquaponics
Dr Wilson Lennard is an Australian scientist with a PhD in Applied Biology. He has studied and installed commercial aquaponics systems around the world. In this extended interview, part three, he turns his attention to Commercial Systems and talks about the reasons why he designed his fish sizing calculator for the home hobbyist. Why is there very little take up of Aquaponics in the commercial arena around the world? Is it lack of knowledge, too new and unknown or just too hard to make it work profitably? Its not to do with making it work...

Dr Wilson Lennard is an Australian scientist with a PhD in Applied Biology. He has studied and installed commercial aquaponics systems around the world. In this extended interview, part two, he turns his attention to back-yard tinkerers in Aquaponics. If you have added Seasol or Maxicrop to your aquaponics system – you may be shocked and a little surprised when he explains why you shouldn’t use the stuff . There seems to be a unusual level of interest in people tinkering and building backyard aquaponics systems around the world....

Dr Wilson Lennard is an Australian scientist with a PhD in Applied Biology. He has studied and installed commercial aquaponics systems around the world. In this extended interview, over the coming days, Dr Lennard will discuss the state of play in Aquaponics research today, as well as his views on how to successfully run a backyard system, a commercial system, his new fish sizing calculator, the alarming flood of “aqua-shysters” as he calls them or marketers that are jumping on the Aquaponics bandwagon and what’s in store...
read moreAloe vera in Aquaponics
Recently while filming in Murray Hallam’s Aquaponics greenhouse we noticed a few odd plants that were growing in the corner of his grow bed. While most people use Aquaponics to grow fresh vegetables like lettuce and tomatoes in their systems, Murray likes to experiment a fair bit and think outside the square, to see exactly what the limits of Aquaponics systems are. By trying to grow some unusual plants like fruit trees and various medicinal herbs and even flowers the evidence seems to point to the fact you can grow almost anything in...

We’re planning a number of exciting new titles to be released in 2011. Urban Permaculture DVD One of the complaints we often get from people living in the city is that we focus a little heavily on Permaculture titles that require a large scale farm to get the most benefit from practicing Permaculture. So we are happy to announce that in 2011 we will be working on the Urban Permaculture DVD with Geoff Lawton. Actually we really started shooting a lot of footage already that we were going to include in the Permaculture Soils DVD that we...
read moreFish Stress in Aquaponics
Aquaponic systems run pretty well for the most part, with minimal supervision needed once all the plumbing is connected and the fish are happy and the seedlings are all planted out. As a food production system, they work exceptionally well. Occasionally however things can go wrong leading to sudden fish deaths. Yesterday the fish looked fine. Today we see a dead fish and tomorrow – another. Whats going on? Is there any one simple answer to their sudden demise? Maybe not one,...
read moreGetting an Aquaponics system started with Bacteria
They are probably the hardest little workers you never get to see or meet or even shake their hand – if they had such a thing. Well actually that’s not entirely true. In fact you do get to shake their hand every time you plant a new seedling in your aquaponics system or plunge your hand into the water to check your fish. Bacteria are the little microscopic creatures that do all the work in an Aquaponics system converting fish waste into food that your plants can absorb. Hundreds and billions of them chugging along, multiplying,...
read moreThe Future of Fish Food?
Its no secret that the world is eating more farmed fish than ever before. According to the World Wide Institute nearly half the seafood the world eats today is farmed. On average, each person on the planet is eating four times as much seafood as was consumed in 1950. Experts predict that farmed seafood will grow an additional 70 percent by 2030. According to fisheries expert Brian Hallweil the world’s greatest growth in fish farming today is occurring with large fish farms raising high-value, predatory fish such as salmon, striped bass,...

One of the fun plants to grow in Aquaponics is strawberries. We all know how great they taste especially if picked fresh and juicy from your own system. They grow very well in conventional gravel grow beds provided your system is reasonably free of salt because strawberries just don’t like the stuff especially if its in the water. A new alternative to the shortage of grow bed space is to grow them in vertical towers. These towers have nutrient rich fish water pumped up to the top the tower and then trickle down through the gravel in the...
read moreDIY Aquaponics DVD
We’re very excited about this next DVD offering from aquaponics guru Murray Hallam because it’s something that he’s been asked to do continually over the years by many people who want to build their own aquaponics system on the cheap from recyclable containers. Murray estimates about 80% of the calls he gets are from DIY people keen to get started in Aquaponics but aren’t exactly sure how to begin. They are after a robust quality system on a budget with components that are available anywhere in the world. So in early...
