Hapa Nets for Mass Fingerling Hatchery Production
The "Hapa Nets for Mass Fingerling Hatchery Production" technology i a cage-like enclosures (referred to as "hapa" nets) placed within ponds to safeguard and manage brooders, hatchlings, and juvenile fish. The hapa nets come in various shapes and sizes, using materials like wooden poles and mesh nets, offering an affordable solution for hatcheries of all sizes. The nets require periodic maintenance to ensure effective functionality, but they significantly improve the management and production of fingerlings for the aquaculture industry. These nets are designed to shield fish from predators, ensuring better control over breeding, feeding, and aeration. They provide a conducive environment for fish growth, resulting in enhanced fertilization rates, reduced mortality, and increased production of fry and fingerlings. This technology is well-suited for various aquaculture species and adaptable to different water bodies such as earthen ponds, riverbeds, or concrete tanks.
This technology is TAAT1 validated.

Utilizing Hapa Nets for Mass Fingerling Hatchery Production streamlines fingerling production, offering fish farmers a cost-effective method. This technology enhances breeding conditions, elevates fingerling survival rates, and promotes sustainable aquaculture methods.
In terms of cost, constructing a hapa using bamboo poles and fine mesh netting typically amounts to approximately US $1 per square meter, with finer meshes incurring additional expenses.
The potential profit from fingerling production in hapa nets varies, ranging from 150 to over 900 fingerlings per square meter monthly. A single hatchery equipped with hapa nets can supply between 8 and 20 fish farmers, delivering significant benefits to the local aquaculture sector.
As this technology is accessible in numerous countries, including Zambia, Uganda, Togo, Tanzania, Sudan, South Sudan, Sierra Leone, Senegal, Rwanda, Nigeria, Niger, Mozambique, Mali, Malawi, Madagascar, Kenya, Ivory Coast, Guinea, Ghana, Ethiopia, Eritrea, Equatorial Guinea, Djibouti, Democratic Republic of the Congo, Central African Republic, Cameroon, Burundi, Burkina Faso, Botswana, Benin, and Angola, ensure to incorporate delivery costs to the business site and account for any import clearance and duties that may apply.
Consider collaborating with agricultural development institutions and agro-dealers for effective implementation.
Additionally, explore the integration of complementary technologies such as All Male Tilapia Fingerlings and Hybrid African Catfish to enhance operational efficiency.
