Impact of Fish

Fish are a valuable source of protein and income. We show community members how to keep them in dams and how to look after them, even when faced with drought.


Fish excretion enriches the water with nutrients that are ideal for irrigating crops and regenerating the land.


Fish are crucial in helping prevent malaria. They eat mosquito larvae, helping the community to control mosquito growth. The fish also work as a great source of stimulus when educating local children on environmental projects, ensuring Haller’s environmental practices and teachings are shared with future generations.


The tilapia fish are sold to provide an income to communities. This also provides communities with a strong incentive to maintain their dams.


Women are empowered through the maintenance of the fish and the income they earn from selling them.
