Utilizing nature to create a zero impact, zero waste, carbon positive, completely self sustainable eco system,
... producing fresh organic fruits , vegetables, fish, crayfish & energy - In our backyard.

Welcome to our adventure ...

Aquaponics is a natural eco-system, which organically produces vegetables, fish & crayfish. It is the integration of fish cultivation, aquaculture, with hydroponic plant production.

Fish wastes are 'filtered' by natural bacteria producing a rich nutrient source for the plants. The plants utilize these nutrients for growth, thus purifying the water to then be returned to the fish. This continuous cycle is what happens in a nature.

Aquaponics has many advantages including, requiring much less space than traditional farming methods, highly efficient food productive method - potentially higher than hydoponics, with zero environmental impact.

- No chemical fertiliser's, pesticides, insecticides or soil conditioners are used.

- Zero water waste. All water is constantly purified by the plants and recirculated back to the fish.

- 100% of all nutrients are used, creating two crops from one nutrient source - the fish food.

- 100% of wastes generated are utilized on site through filters that feed the plants. Worm composts & Black Soldier Fly's are utilized for all vegetable off cuts and house hold waste's, creating natural healthy fish food source's. Worm & BSF castings being used for enhancing soil condition.

- As a source of protein, fish are the most efficient convertors out of all our farmed animals, achieving feed to flesh conversion efficiency close to 100%.

Aquaponics is a 100% natural eco-system.

PVA has also incorporated a totally off grid solar power installation, supplying power for the system, work shed and computers.

Processing your Harvest

Just like the old saying goes, there are many ways to skin a cat... and almost as many ways to clean your fish.
Whole fish with head on / head off, scaled whole, fillets....

I thought I would share my technique for a quick & clean fish cleaning.

Start with plenty of bench space on / near the sink, a nice sharp knife & a container handy for the innards & heads.

Give the fish a quick wash down as this removes most of the body slime and makes it a little easier to handle safely.
Start you first cut from the vent and slice up the belly to the chest, cut from vet to rear of belly also.


Place tip of knife near the lower edge of the gills & above pelvic fins. Pierce down through the whole body and cut cleanly behind the pelvic fin.

Flip the fish over and place tip of knife behind the gill covers & above the pectoral fin. Cut down through the back bone to the top of the head.


At this stage wedge your fingers into this cut to slightly separate the head.
Hold fish over your waste container and  finish the cut to sever the head from the body, most of the innards will simply fall out attached to the head.

Use your knife to scrape away remaining loose innards.

Inside the body cavity you will see the swim bladder attached along the backbone.
Gently cut & scrape along the backbone to help loosen the swim bladder lining away.

Pull away remaining lining and repeat as needed to remove the final bits.

One final rinse and Presto !
Phew.... 6 down & 16 to go !

As silver perch have very small scales I did not bother to scale the fish. If you wish to scale your fish, that would probably be best done as step 1.
