Hi Guys,

The rain started very early this morning and everything looks so green!

Everything is growing very well, we still haven’t lost any of the seedlings and have even added sage, coriander, basil and tomatoes into the spare spaces.

There is a definite line that exists in aquaponics between running a system on seasol whilst waiting for fish to arrive, and the week or two after fish arrive and the system begins to be powered by waste and the nitrite/nitrate/ammonia cycle.

You can almost see the plants grow and count the new buds and shoots daily.

What will be the biggest learning curve for me in the Deep Water System, will be planting patterns, where things grow best in this system, what slows water flow such as the celery, and what plants need the most or least nutrients. This is really very exciting!

The little system is all mapped for us, we know what grows the best where and what we can get each year from the space we have, but this new system is completely different. And its fun, and we love the fact that we can share it all with all of you.

Thanks for following everyone, and welcome to our new followers!

Aquaponics: Fish Farming & Water Gardening. 💧🌱💧🐟💧

Hydroculture (water gardening) may date back to as early as the Hanging Gardens of Babylon, the ancient Aztec chinampas, and the ancient Chinese floating gardens. Aquaponics is the combination of aquaculture (raising fish) and hydroponic agriculture (growing plants in water without soil). Plants naturally filter water for the fish, and fish waste provides organic food for growing plants. Some popular fish choices are trout, catfish, bluegill, and tilapia. Plant choices are nearly limitless, except for plants that require an acidic environment. A backyard greenhouse is ideal for sunlight and natural climate control. Aquaponic gardening uses 90% less water than traditional soil gardening, because the water is re-circulated. Aquaponic gardening yields two foods for one input (fish feed). Plants also grow 2 to 3 times faster in aquaponic systems. Start-up costs are completely worth it once balance is established to gain the renewable rewards and self-reliance. What are your thoughts? Would you try aquaponic gardening?

Farmed fish are breaking out of their pens at an alarming rate
Fish escaping from aquaculture pens is a really big problem, with a really great name: Fishbreaks!

Aquaculture is fast becoming the main way that humans get their seafood fix. But fish aren’t cattle; they don’t turn passive when cooped up. Every year, hundreds of thousands of salmon, cod, and rainbow trout wriggle through damaged or defective cages and flee into the open seas, never to be recaptured. In addition to costing farmers millions in lost revenue, these escapees can wreak havoc on their wild brethren by polluting gene pools and spreading pathogens…

Students assess commercial viability of larva meal

Three students in Cornell’s Samuel Curtis Johnson Graduate School of Management have examined the commercial viability of using housefly larva meal as a sustainable, less-expensive protein alternative to feeding stock and farm-raised fish.

To coax houseflies into hatching larvae, copious amounts of cow manure is needed on which the flies can lay their eggs. Millions of flies can reduce manure mass by half, concurrently lowering manure’s nitrogen and phosphorus content. Meanwhile, the larvae can be harvested as farm feed that is chock-full of protein and essential amino acids.

Protein of high biological value is essential to animal feed. Shortfall of quality protein resources like fish meal poses a future challenge for feeding livestock, said Selvaraj, “Larva meal is an ideal ingredient to replace fish meal with identical protein content and amino acid profile.”

The larva of a housefly (Musca domestica) is pictured much larger than life-size. The larva has been hatched from an egg 1/20of an inch (1.27 millimeter) long. The mouth is at the pointed end.Bitannica Kids

Vertical Farm Grows Crabs in Singapore

Seafood supplier Gills ‘N’ Claws Aquaculture is awaiting approval to do crab farming in a vertical farm in Neo Tiew Lane, specialising in Sri Lankan mud crabs. It will launch its premises, which now houses and fattens ready-to-sell crabs, tomorrow.

Owner Steven Suresh said rearing the crabs here could lower their wholesale price by at least 10 per cent eventually.

He added that the farm’s vertical layout overcomes space constraints. It can also provide fleshier crabs as they are fed and raised here. Imported crabs lose body mass as they are not fed for days en route to Singapore.

The farm’s projected annual output is about 200 tonnes of crab.

Hi All, 

I have often been criticized for the depths of my Deep Water Aquaponic beds, comments to the nature of ‘too deep’ or ‘waste of water’ and even ‘un-traditional’ and some other far out there comments.

But this is why we made them 450mm deep and not the traditional 150-200mm deep the literature recommends. It makes sense when you think about it, if a media based aquaponic bed is recommended to be a minimum of 300mm deep for adequate root growth, why make a deep water bed only 200mm deep!

These celery roots reach the full 450mm depth of the grow beds, (nearly half a metre!) and 200mm outwards under the raft beside it. So much so that the net pots directly next to these need to be empty or risk being over run.

Even at this depth, these roots still slow water flow significantly, and had the beds been shallow ones, these celery roots would have clogged the system up for sure. We are only pushing 1000ltrs per hour through these beds, so its not a great water flow as it is, but i will need to keep a very careful eye on this when the other seedlings begin to reach full size to make sure i have adequate water flow.

Just something to think about.

Have a safe weekend everyone, and WELCOME to all our new followers! Thanks very much for taking an interest in us, in means a lot to us!

A lethal and highly contagious marine virus has been detected for the first time in wild salmon in the Pacific Northwest, according to researchers in British Columbia. It is called infectious salmon anemia, and started in aquaculture salmon farms who import millions of eggs from Europe. The only barrier between the salmon farms and wild fish is a net, opening the way for pathogens to sweep in and out. No treatment exists for infectious salmon anemia. Enjoy those sockeye while you can!

This is Simon the Mud Siren (Siren intermedia). We’ve had him just about two years now and he’s a native capture addition to my freshwater aquarium.

My brother is an avid fisherman and sometimes, while he’s netting for bait, he picks up some rather odd finds. Occasionally he’ll find something neat and ask if I’m interested. Normally I’ll turn him down but Simon was just so amazing I had to hang on to him.

Simon is about 8 inches long and enjoys Tubifex worms and his favorite place in the tank is underneath a piece of driftwood I’ve covered with Java Moss. The driftwood is propped upon a few stones so it makes a nice dark cave for Simon whose species is known for burrowing into the mud.

Hi Everyone!

Ok, so an update for you on the Deep Water Aquaponics System.

If you remember, we began planting this system on 9 March this year, so that makes it around 40 days from planting.

The standout for me are the red lettuces. They have turned a deep red colour and look great! Have a look at the first days planting and see what you think!

The Silver Beet too, the last week has seen a big jump in growth.
In fact since we added the aeration and the trout, it has leaped forward in health and growth.

The only significant laggers are the strawberries, they are very slow compared to the leafy greens both in foliage and root growth.

Other than that, the new system is really showing promise very early. It is yet to finish cycling, but it will get there! 

Very Happy!
