Sprouting Good’s Aquaponics

Sprouting Good's Aquaponics 01

We would love to introduce you to the wonderful world of Aquaponics. Aquaponics is the cultivation of plants using the waste water from fish or aquatic creature which supplies the nutrients for the plants. Those using Aquaponics at home will be able to deliver fresh healthy chemical free produce in their backyard with the benefit of having access to fresh fish. Our specially designed education centre has been teaching students […]

The Four Fish We are Over Eating – And What to Eat Instead

The Four Fish We are Over Eating – And What to Eat Instead

The way we fish for popular seafood such as salmon, tuna and shrimp is threatening to ruin our oceans. Paul Greenberg explores the sheer size and irrationality of the seafood economy, and suggests a few specific ways we can change it, to benefit both the natural world and the people who depend on fishing for their livelihoods.

Gimponics: Backyard Aquaponic grower produces garden of plenty

Eric Stewart checks out this productive edible suburban home in Holiday, Florida. Check out Steve the “Gimponic” who grows several hundreds of pounds of fresh vegetables, fruit, and Fish from his hybrid aquaponic garden. He uses the aquaponic fertilizer to grow his garden. He also has chickens to help fertilize and take care of his extra waste. Anything his family doesn’t eat or juice goes into the dehydrator or fermentation […]

Ripping Yarns

Only 0.01% of our seas are protected, and even the top conservation sites are up for grabs. A few days ago, I visited the Flamborough Head “no take zone”, one of the UK’s three areas in which commercial fishing is prohibited. Here marine life is allowed to proliferate, without being menaced by trawlers, scallop dredgers, drift nets, pots and all the other devices for rounding it up, some of which […]

Geoff Lawton visits the Hawaiian Island of Molokai where an 800-year-old traditional fish farming system is being restored. Fish farming has been practiced for centuries in many cultures. The Hawaiians built a sustainable system that worked from the top of the mountain range and ran right down to the base and out to sea. The Hawaiians built a network of terraced gardens – small spring systems in the upper slope […]

Stephen Palumbi: The Hidden Toxins in the Fish We Eat (TED video)

There’s a tight link between the ocean’s health and ours, says marine biologist Stephen Palumbi. He shows how toxins at the bottom of the ocean food chain find their way into our bodies, with a shocking story of toxic contamination from a Japanese fish market.

World’s Largest Aquaponics Project, in China’s Third Largest Aquaculture Lake

Lake Taihu experienced its worst ever algal bloom at the height of summer, pushing researchers to search for new solutions. They decided to try a new technology, Aqua Biofilter, that is designed to remove nutrients that fuel algal blooms. An ambitious aspect of the project was to launch the world’s largest aquaponics system, over 4 acres in size, using new technologies in combination with old world bamboo that is used […]

FoodWaterShelter Fast Fact: Tilapia Fish Farming at Kesho Leo Children’s Village (Tanzania)

At Kesho Leo we have tilapia, a freshwater fish species that is hardy and easy to farm in relatively small ponds. This makes it a perfect choice for farming families in our area. Tilapia are omnivorous, but the species we are farming (Oreochromis nyloticus, Nile tilapia) feeds primarily on phytoplankton and algae.

The Perfect Permaculture Fish Pond

Screen Shot 2016-06-14 at 12.42.32 pm

Geoff’s 800 square meter pond is shaped like a soup plate with a perfectly flat 2m deep bottom, ideal for growing out fish of all types.

This particular pond was allowed to mature and develop. Consequently it was overgrown with weeds and grass. To clean out the system, Geoff decided to drain the pond partially so he can use cows to graze right down to the water’s edge. He then moves them off a few days later, when the task is complete. A lot of people have read about soil compaction caused by over-grazing by cattle and sheep, turning the soft soil into a hard concrete pan and resulting in soil erosion and land degradation. People balk at using animals near a water system these days. But here, Geoff uses the cows and horses to quickly blitz the water’s edge before moving them away.

Less Than 3 Percent of Oceans in Marine Parks Despite Recent Growth

by J. Matthew Roney, Earth Policy Institute Photo credit: Dr. James P. McVey, NOAA Sea Grant Program In May 1975, rising concerns about overfishing and deteriorating ocean health prompted scientists and officials from 33 countries to meet in Tokyo for the first global conference on marine parks and reserves. Noting the need for swift action to safeguard more of the sea, the delegates were unanimous in calling for the creation […]

Aquaponics on the Cheap!

You don’t have to be loaded to get started with a really simple aquaponics setup! As a variation on the system shown in the video, you can (in a warm enough region/time of year) place the system outdoors on a hillside where each grow pipe set loops back and forth over greater distances or more times and each fish tank overflows into a subsequent basin with a pipe and ‘grow […]
