This work was undertaken as part of the CGIAR Research Program on Fish Agri-Food Systems (FISH) led by WorldFish. The program is supported by contributors to the CGIAR Trust Fund. FISH is developing the better management practices (BMP) guidelines at the global level and contextualized BMP resources at the country level to support sustainable and responsible tilapia farming in WorldFish focal and scaling countries.
Tilapia hatcheries are the most common type of fish hatchery in Egypt. They are nearly all private sector businesses, and their success in supplying fish farms with tilapia seed has contributed to the increase in national farmed fish production. There are three different hatchery systems used for Nile tilapia: (1) concrete tanks with a water-heating system, (2) hapas under plastic tunnels and (3) hapas in open ponds. The fish farming industry is growing quickly, and tilapia hatcheries have to improve the quality of seed production for fish farmers to maintain their profit margins.
Nile tilapia (Oreochromis niloticus) is one of the most important aquaculture species farmed worldwide. However, the recent emergence of tilapia lake virus (TiLV) disease, also known as syncytial hepatitis of tilapia, has threatened the global tilapia industry. To gain more insight regarding the host response against the disease, the transcriptional profiles of liver in experimentally-infected and control tilapia were compared.
Antibiotics are used in aquaculture to maintain the health and welfare of stocks; however, the emergence and selection of antibiotic resistance in bacteria poses threats to humans, animals and the environment. Mitigation of antibiotic resistance relies on understanding the flow of antibiotics, residues, resistant bacteria and resistance genes through interconnecting systems, so that potential solutions can be identified and issues around their implementation evaluated. Participatory systems-thinking can capture the deep complexity of a system while integrating stakeholder perspectives.

The WorldFish objective for sustainable aquaculture within the CGIAR Research Program on Fish Agri-Food Systems (FISH) focuses on enabling enterprises to progressively enhance production of aquatic foods in a more efficient and sustainable way. This is achieved by using domesticated, selectively bred, healthy fish reared on sustainable feeds in gender-inclusive production systems that have low carbon footprints with limited adverse environmental impacts.
WorldFish focuses on testing technologies that improve the productivity of fisheries and aquaculture and strengthen value chains to increase incomes of fishdependent people in Zambia and throughout sub-Saharan Africa. WorldFish works in the Barotse Floodplain of western Zambia where its research focuses on testing improved fish processing technologies and social innovations to reduce post-harvest losses and improve gender relations throughout the fishery value chain.
Since launching its research program in Egypt in 1998, WorldFish has delivered high quality, practical research related to the country’s aquaculture and fishery sector. A key research focus has been on improving fish genetics to transform Egypt into a role model for African aquaculture development. WorldFish works closely with aquaculture stakeholders, the private sector and government organizations to deliver research on increasing aquaculture productivity, increasing the flow-on benefits of fish farming to women and youth, and enhancing fish value chains.
Aquaculture is a promising sector of fish industry in the world with about 80 million tones being produced annually. The development of aquaculture faced several constraints; among these are diseases constituting the most limiting factors. Bacterial infections, pose one of the most significant threat to successful fish production throughout the world.
Tilapia lake virus is a newly emerging virus that is associated with significant mortalities in farmed tilapia. With cases reported across Africa, Asia and South America, the virus represents a huge risk to the global tilapia industry, whose 2015 production was valued at USD 9.8 billion. All countries with a tilapia industry must be vigilant and act quickly to investigate cases of mortalities in farms.
