DIY Project: A Garden Fish Tank

How To Build A Small Indoor Aquaponics System

Aquaponics is a system for the sustainable production of food that combines aquaculture (raising of fish, crayfish, talapia or shrimp in tanks) with hydroponics (the cultivation of plants in water with no soil).

This is a symbiotic relationship because the plants and fish both benefit from living together. The plant’s roots clean the water of ammonia and toxins, which helps the fish - while the fish provide the plants with nutrients, which are obtained from the fish pee and poop, as well as from ammonia excreted from the fish gills.

Farm Towers & Fish Farms

In 50 years, the human population will reach 8.6 billion, which means we’d need land “roughly the size of Brazil” just for growing crops to sustain the human population. Rather than expanding out, some are suggesting we grow upwards, via vertical farming. Out in the oceans, fish farms sometimes have fishbreaks, when farmed salmon, cod, and trout break free from defective cages and escape into the open ocean. Not only is this millions of dollars of lost revenue for fish farmers, the freed fish could also wreck the surrounding ecosystem.  Read more…

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!

Seaweed farming in South Korea

Would you have guessed that that these meticulously arranged polygons in the ocean off the southern coast of South Korea are farms? The patchwork patterns are actually fields of seaweed — the seaweed is grown from ropes and buoys that keep the seaweed near the ocean’s surface for optimum sunlight.

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?

Fish farms get a bad rap, but could they save the planet? 

The world’s population is expected to soar by 2.5 billion people by 2050, bringing a host of global challenges – including how to feed so many hungry mouths.

If projections hold, the global demand for animal protein (meat, poultry, fish, eggs) will double over the next four decades. How can we produce this much food sustainably?

Currently, over two-thirds of the animal protein we consume globally comes from land: beef, pork and poultry. When it comes to global warming, this is a big concern. Up to a quarter of the greenhouse gas emissions — which warm the planet — come from meat production.

But there may be a more sustainable solution: seafood.

Aquaculture — “farms” for fish, shellfish, and algae — could help meet our rising protein needs while protecting our planet, said Steve Gaines, dean of the Bren School at UC Santa Barbara.

But there’s one big catch: Aquaculture has gotten a bad rap with American consumers.

“There are some really bad ways to do aquaculture, but if you look at best practices, they are dramatically better than any production on land,” Gaines said. “In many cases, it’s 50 to 100 times higher environmental impact to produce on land than in the ocean.”

Gaines has been working to change minds about aquaculture, speaking at conferences around the country like this week’s @montereybayaquarium Sustainable Foods Institute.

While some forms of aquaculture can harm the environment, others have a much lower impact, especially when compared to land-based protein — and in some cases even compare favorably to an entirely vegetarian diet, he said.

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…

‘Dory’ Bred in Captivity for First Time
Breeding the popular blue tang in captivity is an important step toward protecting wild fish and reefs from destructive practices.

Remember my article a few weeks ago about Finding Dory and not purchasing a ‘Dory’ for your aquarium as it hurts the wild population?

Well, things may be changing for the better. On July 19, 2016, scientists from the University of Florida Tropical Aquaculture Lab announced that blue tangs have been bred in captivity for the first time.

This breakthrough is good news as it means that aquarium hobbyists and marine life exhibits may soon have a source for blue tangs that doesn’t rely on wild fish, often captured by illegal and destructive means. 

For now, this finding is still in its early stage and all the blue tangs you will see for sale are still taken from the wild. Don’t get a Dory quite yet, and if you really want one, be patient and hopefully you will be able to get a captive-bred one fairly soon.

A farm designed to restore oceans and planet health, whilst providing food for people.

Since there is no need for fresh water, fertilizer, or pesticides, restorative ocean farming is a sustainable form of food production.

As a food crop, seaweed is rich in nutrients such as protein, calcium, and vitamin-C. Recent studies demonstrate that a network of seaweed farms the size of Washington State could produce all of the dietary protein needs of the human population.

The farms use restorative and foundational species that provide habitats for hundreds of marine and bird species; creating natural reef systems that harbor hundreds of wild species.

The farm model and technologies are open source.

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

I haven’t done an update on my main tank for a while.

3ft - 170 litre - Freshwater Community.

-Pair of Pearl (Lace) Gourami’s.
-Nine Black Widow Tetras.
-Eight Danios (Pearl, Leopard, Zebra).
-Twenty two Neon Tetras.
-Twelve Peppered Corydora’s.

I have changed some stuff around and removed/moved some plants. I’m pretty happy with how it’s looking at the moment.

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!
