Aquaponic in Sierra Leone: Project progress and lessons learnt

The Salone Aquaponic project is now ongoing for over 3 years. We installed a first test system at the Salone Aquaponic office in Freetown. Expansion plans are made to further expand the system to a commercial viable operation. Several hotels, businesses and private customers have expressed their strong interest in pruchasing fresh and organically produced local vegetables and herbs. Here are some pictures from our current crops. The arabic mint is performing great with good taste!

Arabic mint is performing great in the aquaponic system. The mint leaves give a great tea and spice up your salads, like tabouleh and couscous salad.

Italian basil, a intensive flavour, great for pizza, pasta and salads.

Aquaponic farming: The sustainable way of fish and vegetable production

Aquaponic offer 2 benefits in one: It produces delicious fish, like Tilapia and also produces fresh vegetables by converting the fish poop to organic fertilizer. Especially in development countries, aquaponic can be a new way of farming, in areas of low soil fertility or in urban areas.

Delicious fresh mint has a high market price in Sierra Leone. It can be used for fresh tea and for salads.
Parsley grow excessevly in the NFT system. It produces more than we can eat. Parsley can be fed to the Tilapia

Parsley, onions, mint and tomatoe update on aquaponics

Here are some updates on the aquaponic system in Freetown, Sierra Leone. Parsley, onions, mint and tomatoes are growing well... Looking forward to sell the parsley from the NFT system to a nearby restaurant soon!

Tomato plant harvested, one tomatoe still left!!!

Real onions and mint growing in the media bed.

Tomatoes are a real opportunity due to their demand and high market price

Pepper plant having plenty of mealy bugs but still bearing fruit. The pepper was an imported hybrid variety. next time we go with the local seeds!

Harvesting tomatoes and corn from aquaponic

It is harvest time: After 2 months of growth we can harvest the first tomatoes and corn from the aquaponic system. With the aquaponic technology we are able to produce vegetables, like tomatoes and corn throughout the year without depending on the season. Stay tuned.

Aquaponic system update: Tubers and maize performing well

Our latest update on the growth of our plants in the aquaponic system: Tomatoes, maize, parsley and sweet potatoes showing strong growth. A suprise was the performance of the sweet potatoes, which are tubers with excess leave growth. Sweet potatoes are a staple diet for many Sierra Leoneans, better know locally as "petete lif". Aquaponic tuber production might be an option to counteract extreme high food prices of foods like potatoe leaves in Sierra Leone.

Inside Aquaponics in Africa

Aquaponics production methods is a combination of aquaculture and hydroponic plant production in a closed cycle. Aquaponics is considered to be a highly sustainable grow system that can grow a wide range of plants and rear nutritious fish at the same time. After 5 weeks from restarting our aquaponic system in Sierra Leone we can see both plants and fish growing fast. In order to feed the fish, we use a self made feed formulation consisting of dried fish, moringa leaves, rice bran and vegetable oil. The fodder makes both plants and fish grow well.
Aquaponic require no soil: Plants grow on granite gravel only
Tubers like sweet potato grow well in aquaponic media bed: Potato leaf in Sierra Leone is a main diet for people

Parsley is highly expensive in local markets in Sierra Leone. Aquaponic is a great way of making profit in a short time.

Salone Aquaponic system with new tilapia stock and new vegetables started

In order to have a high producing aquaponic system a constant power supply is needed.
The aquaponic system with a new stock of Tilapia (oreochromis niloticus) is beginnig to grow back with new vegetables. The aquaponic system is currently growing parsley, salad, tomatoes, onions, mint, peas, ginger, rice, pineapple, basil and carrots. After installing a solar panel and a battery back up, to sustain prolonged powercuts the system is able to revive productivity throughout the year. Aquaponic has great potential in Africa to produce high class vegetables regionally and cost efficient. Stay tuned for more aquaponic news soon.

Aquaponic technology in Sierra Leone: Young fish, groundnuts and green pepper

Hi readers, it´s been a while since our last post. Many things happend at our aquaponic project site.
Although the electricity in Freetown is barely available more then 8 hours per day, we still managed to keep the system alive.
The fish even strated to breed and we had many young ones. Through an long lasting power cut of several days, we were forced to eat the big fishes in order to prevent them from dying because of lack of oxygen as the pump did not run. Currently we only have 4 fish left from the offspring. We managed to harvest a ripe chili although the nitrates are currently low. In a few weeks we will install a sustainable solar and wind power system to supply environmental friendly electricity.


Peppers, groundnuts and tomatoes
Although lack of nitrogen, due to very low fish density, the green pepper is growing and will soon end up in the stew
Ginger is growing
Green leaves showing signs of low nitrates. More fish need to be added in the system.
Hawa harvested the first aquaponic groundnuts from the system. Boiled in salt water they are an excellent and healthy snack.
