The Challenges & The Opportunity

The Challenges

Population Growth

Tanzania, East Africa – the land of the Kilimanjaro, Zanzibar and the Serengeti … and one of the fastest growing countries in the world: Until the year 2050 its population will have more than doubled, from 50 million in 2019 to over 100 million people in 2050 (FAOSTAT, 2019).

High Fishing Pressure

While Tanzania’s population is vastly increasing, its fish and aquatic life stocks are rapidly wasting away. This is due to various reasons such as overfishing, pollution and overall missmanagement of lake environments. As a consequence, wild fish catches have been almost stagnating during the last three decades (FAO, 2020).

The Opportunity


Although aquaculture has long been realized to be a solution to the problem of declining fish supply, only about 2-3% of the fish consumed in Tanzania currently derive from aquaculture (FAO, 2020). The three main constraints for aquaculture development in the country are the scarcity and high cost of high-quality inputs, the lack of know-how and the lack of capital (Rothuis et al., 2014).

Fish farming in Tanzania and East Africa will become a multi-billion-dollar industry in the next few decades. Due to lacking supply chains most aquaculture ventures aim for large scale operations (investment >5 million USD) to be able to integrate the whole aquaculture value chain into their operations.
In the long term it is therefore important to think about how the aquaculture sector can develop in the most sustainable way so that not only large corporations benefit from the opportunity.

What is Bongo Samaki?

Our Mission

Our mission is to provide high quality, affordable aquaculture inputs (feed, fingerlings, equipment) to the Tanzanian fish farming sector and advice and train people on how to farm fish profitably and sustainably. Thereby we especially address smallholder farmers and small to medium enterprises (SMEs).

Our Vision

We want to make Tanzania a fish farming nation where aquaculture is carried out in a sustainable manner all over the country by lots of different people, thereby creating income, employment, ensuring food security and decreasing fishing pressure on natural water habitats.

Our Projects

Bongo Samaki - Dar es Salaam

In Dar es Salaam we operate a small pilot tilapia hatchery and R&D facility. In the past few years we have been using the facility to start a healthy broodstock population, test inputs and conduct growth trials.

The goal is to expand the hatchery to reach a capacity of 1 million fry and 1 ton of table sized tilapia per year.

Furthermore we are planning to supply other aquaculture projects in Tanzania with high quality equipment such as water quality measuring equipment, air pumps and pond liner from our facility in Dar es Salaam.

Mulimuli - Dar es Salaam

Mulimuli is a community project initiated by Teddy’s Home Hostel and registered as a community group organization in Dar es Salaam. Together with Bongo Samaki the project tackles the high youth-unemployment in urban communities through a combined approach of tourism, farming and capacity building.

The core idea of Mulimuli is to combine backpacker hostels with community centers – creating places for inspiration and change.

You can find more information in the annual reports of Mulimuli (2019, 2020).

The Tanganyika Aquahub - Kipili

Together with the Lake Shore Lodge we are currently establishing a pond culture facility in Kipili at Lake Tanganyika.

The project will consist of a fish farming training center and a commercial fish farm. The goal is to reach an annual production of >2 million fry and 50 tons of table-sized tilapia (endemic Tanganyika tilapia).

You can find more information in the most recent annual report of The Tanganyika Aquahub.

Interested in Fish Farming?

Are you interested in fish farming? We’d love to share our passion with you – here is how we can help you …

Consultation and Training

We are happy to consult you on your existing or future fish farming project.

Moreover, we are glad to accompany you through your whole fish farming journey from planning to the finished setup including training of staff and management.

For a one-day visit (e.g. site inspection of ca. 3-4h) we charge 40’000 TZS (~18 USD) excluding transportation (public transport and pikipiki or bajaji). For smallholder farmer groups or similar organizations we may also consider to give you a visit free of charge.
Further consultation fees depend on the size of the project. We may also agree on a result-based payment or we may be interested in establishing a joint venture together with you. Get in contact with us to discuss your project further.



We sell mono- and mixed-sex tilapia fingerlings (Oreochromis niloticus). Please plan ahead of time if you need fingerlings and place an order 1-2 months before you need the fingerlings.

We charge 200 TZS (~0.09 USD) per fingerling/fry and can get them to you either in a water bucket or oxygen filled plastic bags (depending on your location).

Fish Feed

Feed is still a big constraint in the aquaculture sector in Tanzania as there is no high-quality production facility of commercial fish feeds in the country. If you are in need of commercial fish feed (floating pellets) we can help you to import it or find existing importers. However, current prices of high-quality fish feed are very high at around 3’000-3’700 TZS/kg (1.30-1.60 USD/kg) for grow-out feed and up to 5’000-6’000 TZS/kg (2.15-2.60 USD/kg) for starter feed.

If you want to farm in ponds (not cages or RAS in tanks) we advice you to consider the production of your own feeds on your farm. We are happy to assist you with that and show you how to do it and find a suitable feed formula that is cost-effective depending on the available raw materials in your region.

Other Equipment

We are planning to import various equipment in the future. This includes water quality measuring equipment, air- and water pumps and pond liner.
