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.

In total, 2341 smallholder farmers participated in the census: 61% in Northern Province and 39% in Luapula Province. Of the overall total, most (72.1%) were actively involved in fish farming, while the rest had abandoned the practice at the time of the census. Most of the farmers were men. The average age of the farmers was approximately 44.3, with young farmers (defined as farmers aged between 15 and 35 years old) accounting for less than one-third of the total.

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.
