Why We Chose Gambusia to Combat Malaria in Sierra Leone
Do good and it will come back
to you double.

We selected Gambusia fish for malaria control in Sierra Leone due to their proven effectiveness in reducing mosquito populations. These fish are highly efficient at consuming mosquito larvae, with each fish capable of eating up to 300 larvae per day. Their ability to thrive in various water conditions makes them an ideal, low-maintenance solution. Unlike chemical treatments, Gambusia are environmentally friendly and sustainable, providing a natural method to decrease malaria transmission and improve public health in the region. Their use aligns with our commitment to innovative, eco-friendly approaches to combat malaria.

Breeding and Selection of Gambusia Fish
Gambusia, commonly known as mosquito fish, are pivotal in controlling mosquito populations and reducing malaria transmission. These hardy fish, native to North and South America, thrive in various environments and are known for their voracious appetite for mosquito larvae.

Breeding Gambusia
Gambusia are livebearers, meaning they give birth to live young rather than laying eggs. Breeding them involves creating a suitable environment with clean, shallow water and ample vegetation for hiding. The gestation period for females is about 4-6 weeks, after which they give birth to 20-40 fry. To increase survival rates, providing plenty of hiding spots for the fry is crucial, as adult fish can sometimes eat their young.
Selection for Disease Control
Selecting the right Gambusia involves ensuring they are healthy and free from diseases. Fish should be active, with clear eyes and no signs of fin rot or other infections. The chosen fish should also exhibit a strong appetite for mosquito larvae. For large-scale breeding, starting with a genetically diverse group helps maintain a robust population capable of thriving in various environmental conditions.

Expanding Use in Public Health
Due to their effectiveness, Gambusia are being introduced in different parts of the world to combat malaria. Efforts are underway to establish breeding programs in regions where malaria is prevalent, ensuring a steady supply of these beneficial fish. Public education campaigns are also crucial, teaching communities how to maintain and monitor Gambusia populations in local water bodies.
Deployment of Gambusia in Small and Large Tanks

In combating malaria through biological control, Gambusia fish have become an integral component. These fish are strategically placed in water tanks to control mosquito populations by consuming their larvae. Small plastic tanks cost $0.40 each and typically house around five Gambusia. These smaller setups are ideal for limited spaces.

On the larger scale, tanks costing up to $200 can accommodate approximately 250 Gambusia, handling about 500 liters of water. These larger tanks are often split into two separate aquariums to optimize space and ensure the health of the fish. The recommended density is one fish per two liters of water, although a slightly higher concentration can be sustained without compromising the system’s efficiency.

Such deployments are not only a testament to the effectiveness of Gambusia in mosquito control but also highlight scalable solutions for public health challenges in regions prone to malaria.

A circular solution tackling malaria, plastic pollution, and rural livelihoods
Across Sierra Leone, discarded 5-gallon (roughly 20-liter) plastic tanks—originally used to store vegetable cooking oil—are an increasingly visible part of the landscape. These small high-density polyethylene (HDPE) containers are found in backyards, roadside dumps, and riverbanks, contributing to a growing environmental problem. According to the UN Environment Programme (UNEP), Sierra Leone produces over 130,000 tonnes of plastic waste each year, yet only around 5% of it is formally recycled. The rest ends up in open environments, where it poses long-term risks to public health and ecosystems.

A Day in the Life at SAFMI's Fish Farm
Once the environment is set, the team carefully transports all newborn fry from the overnight incubators. These incubators represent one of our proudest innovations — a system designed to automate fish breeding and maximize the number of healthy fry. Thanks to a gentle stream of air, newly born fry are pushed safely into a separate area of the aquarium, away from larger fish. Here, the tiny fry will spend a day growing stronger before being carefully transported into larger aquariums with the other fry.
