Tilapia lake virus (TiLV): Putting a global resource at risk

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.

Experimental infection reveals transmission of tilapia lake virus (TiLV) from tilapia broodstock to their reproductive organs and fertilized eggs

Early developmental stages of tilapia, including fertilized eggs were tested positive for TiLV in a previous study. We, therefore, hypothesized that infected broodstock is able to pass the virus to their reproductive organs and then to the fertilized eggs. In order to prove this hypothesis, Nile tilapia (Oreochromis niloticus) broodstock were experimentally infected with TiLV by intramuscular injection and non-infected broodstock were used as control group.

WorldFish in India

India is a scaling country for WorldFish and the CGIAR Research Program on FISH. This growing program assists the government and private sector to scale various fisheries and aquaculture technologies in India.

AquaLINC Project Final Workshop

In Bangladesh, the aquaculture production has grown rapidly with the production of fish from aquaculture in 2017-2018 being 24.5 lakh MT, accounting for 56% of total fish production. Within the aquaculture sector, the production of tilapia has grown rapidly from 15,000 MT in 2006-2007 to, 3.85 lakh MT in 2017-2018. It has been projected that in 2030, the total aquaculture production of the country could potentially reach to 80 lakh MT with the production of tilapia being 10 lakh MT.

Tilapia major clinical signs (Khmer version)

The purpose of this poster is to enhance the capacity of hatcheries, nurseries, grow-out farmers and extension service providers to recognize and report tilapia diseases. Prevention, early recognition, diagnosis and rapid intervention are the best steps to manage aquatic animal diseases. If you observe clinical signs, abnormal behaviour and unusual mortality, contact your local aquaculture health professionals to report and ask for support.

Partnership for Aquaculture Development in Timor-Leste (PADTL): Development of sustainable aquaculture in Timor-Leste (Tetum)

In 2012, the National Directorate of Fisheries and Aquaculture (NDFA), Ministry of Agriculture and Fisheries (MAF) Timor-Leste developed the National Aquaculture Development Strategy (NADS) 2012-2030 with technical assistance from WorldFish. The New Zealand Aid Programme funded a 5-year project to support development activities identified within the NADS. The National Directorate of Aquaculture (NDA) takes a pivotal role in implementing the project, with WorldFish providing technology and training/mentoring support.

Partnership for Aquaculture Development in Timor-Leste (PADTL): Sustainable GIFT seed production and dissemination model in Timor-Leste (Tetum)

Assured supply of quality seed is key to sustainable intensification of tilapia production in Timor-Leste. Enhanced availability of and improved access to seed hinge upon the establishment of a network of government and private hatcheries and nurseries for widespread distribution to farmers.
