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 in Sierra Leone for vegetables and tilapia rearing

The aquaponic system is producing various herbs and vegetables as well as delicious Tilapia fish, which are a good source of protein. Aquaponic is a good way of mitigating the high food costs in aquaculture by providing extra income from the plants. Furthermore aquaponic systems act as a cost safer, when it comes to filtration: Whilst in traditional aquaculture, filtration to remove nitrates and toxins from the system is an expensive task, also, because of the amount of fresh water to be exchanged in order to maintain water quality. In an aquaponic system, plants act as a bio filter by removing the ammonia and nitrates from the system, while providing extra income for the farmers and also safe fresh water. Aquaponic is a good and sustainable farming solution for Sierra Leone, to provide high quality organic food to people.

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.

The aquaponic system: Growing maize, ginger, salad, peas, tomatoes, onions, sweet potato and parsley

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.

We have planted a young cocoa seedling, which we found behind our house. As we can see, the tree has started to produce fresh leaves. This is the first cocoa tree that grows in an aquaponic system.

The tilapia have breeded and now we have many youg fish in our tank.
