♪ ♪ I'm Rikalize Reinecke, I'm 14 years old.

I live in South Africa, Pretoria.

My farm, I live with my father and my mother, and then my little brother Gertladewyk.

My brother takes care of the wild animals.

It brings me into the nature, and I feel happy when I'm feeding them.

We have 13, 14 impalas.

And we have around about five nyalas.

And I designed and built the aquaculture and aquaponics farm.

Let me show you.

After I watched the movie "Dolphin Tale," I was so inspired I wanted to become a marine biologist.

But then I realized I can't become a marine biologist because over ten years there won't be enough fish in the sea left.

Then I decided I needed to do something to that problem.

Aquaculture is basically fish and water.

So it would be a system with filters that filter the water so the fish can stay in that water.

I first started with the fish, but then I decided to do aquaponics, which is plants and water and then fish.

And the water that I use from the aquaculture I can actually reuse in the aquaponics because the waste of the fish can be reused as fertilizer so that the plants can grow.

So the fish is feeding the plants.

What the plants do is to help to filter my water so that the fish can grow faster.

So how it works here is the plant is planted in little buckets.

The roots will grow through the little bucket spaces, and then this little bucket will just hang in this pipe, and the water will just flow through the pipe.

And then the plants, it's an extra filter system so that the water can be clean for the fish.

I have around about 17,000 fish.

And in a year, it can produce almost three tons of veggies.

The taste is so much better than any other veggie that you have ever tasted.

Because they are 100% organic with no growth hormones.

This is "spinosie" in Afrikaans, but in English it's "spinach."

Over here is strawberries.

In Afrikaans it'd be "arbeie."

I would call it like finger lettuce.

80% of all the construction here in my whole farm, I built it with my own two hands.

It's around about almost a kilometer of pipe in my whole system.

I started with a straight line of pipe like this, and then just adding an elbow, just connecting it like that.

And after that I will just put another piece underneath and connect it to the part below.

And I drilled holes in it so that the buckets of the plant can fit perfectly into the hole.

My father welded the frame, and then he just came and cable-tied the pipe onto the frame so it won't fall off.

It took us about a month to build everything.

The plants will actually bring me money in so then I can use that money to expand my business more so that I can produce more fish.

Most of the fish in here are around about 500 grams, which is ready to harvest.

After we harvest the fish, they go to restaurants, chef schools, hotels, supermarkets.

This is my tunnel where I hold all my long table dinners.

What I do is I invite a culinary school, and then all the chefs, they make different dishes with all the veggies and the fish in my tunnels.

So what happens is you have the people come and they will sit and have a great meal.

And this is mostly for the marketing of my business.

My farm can produce around about four tons of fish.

My ultimate goal is to reach ten tons of fish.

So I am busy building a second phase.

I want to do this forever and I want to be a fish farmer.

I started my business on the age of 12 years old.

So you can be any age to do something.

If you have the passion you can do anything.
