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.

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.

Biosecurity in tilapia production

A presentation given at The World Organisation for Animal Health (OIE) held the 4th Global Conference on Aquatic Animal Health from 2 to 4 April 2019, in Santiago, Chile. Tilapia is very important for food and nutrition security, livelihoods and income for rural households in Asia and Africa. Importance attached to biosecurity and health management must be at the same level as for shrimps and salmon. This calls for a massive change in the way farmers, researchers and policy makers treat carps and tilapia with respect to overall biosecurity and health management.

Typology of interventions aiming to reduce antimicrobial use (AMU) in aquaculture systems in low and middle-income countries

This poster aims to conduct a typology analysis of interventions to reduce antimicrobial use (AMU) in aquaculture systems of low and Aim middle income countries and provide an overview of the policy landscape affecting AMU. Poster presented at the Second international conference - Quantification, Benchmarking and Stewardship of Veterinary Antimicrobial Usage, held in Bern, Switzerland from 2-3 July 2019.

Dietary administration of probiotics modulates non-specific immunity and gut microbiota of Nile tilapia (Oreochromis niloticus) cultured in low input ponds

Poor culture conditions in low input ponds make fish highly susceptible to infectious pathogens which lead to diseases and mortalities yet the effects of probiotics on immunity, gut microbiota and microbiological quality of fish in low input ponds are unknown. Nile tilapia, Oreochromis niloticus fingerlings (40 g) were randomly stocked at 50 fish m-3 in 1.25 m3 cages in low input ponds. The fish were fed on diets supplemented with either Saccharomyces cerevisiae (1 × 1010 CFU g-1) or Bacillus subtilis (1 × 109 CFU g-1) at six levels: Diet 0 (No probiotic); S.

Identifying hotspots for antibiotic resistance emergence and selection, and elucidating pathways to human exposure: Application of a systems-thinking approach to aquaculture systems

Aquaculture systems are highly complex, dynamic and interconnected systems influenced by environmental, biological, cultural, socio-economic and human behavioural factors. Intensification of aquaculture production is likely to drive indiscriminate use of antibiotics to treat or prevent disease and increase productivity, often to compensate for management and husbandry deficiencies. Surveillance or monitoring of antibiotic usage (ABU) and antibiotic resistance (ABR) is often lacking or absent.

Tilapia major clinical signs (Malay version)

Tujuan poster ini adalah untuk meningkatkan keupayaan pengusaha ternakan di peringkat pengeluaran benih, asuhan dan pembesaran untuk mengenali dan melaporkan penyakit tilapia. Pencegahan, pengenalan, diagnosis dan intervensi pada peringkat awal adalah langkah terbaik untuk menguruskan penyakit haiwan akuatik. Jika anda melihat tanda-tanda klinikal, tingkah laku yang tidak normal dan jumlah kematian yang luar biasa, hubungi bahagian biosekuriti perikanan setempat untuk melaporkan dan meminta bantuan.
