Assessment of the impact of dissemination of genetically improved Abbassa Nile tilapia strain (GIANT-G9) versus commercial strains in some Egyptian governorates

WorldFish initiated a selective breeding program in Abbassa--Egypt to develop and produce the genetically improved Nile tilapia strain known as “Genetically Improved Abbassa Nile tilapia (GIANT)”, adopting the same technology used for the Genetically Improved Farmed Tilapia (GIFT), in Asia. WorldFish provided the Ninth Generation (G9) broodstock of the GIANT to 11 Broodstock Multiplication Centers (BMC’s) in five governorates; these centres then disseminated improved mixed-sex fry to 160 tilapia hatcheries which supplied all-male fry to 1,500 fish farms in 2017.

Better management practices for genetically improved farmed tilapia (GIFT) in Timor-Leste

Worldwide, the demand for fish continues to grow rapidly. Sustainable intensification and expansion of aquaculture and innovations in fish production systems will be needed to meet this increased demand. It is with this in mind that WorldFish’s 2017–2022 strategy and the CGIAR Research Program on Fish-Agri-Food Systems (FISH) (2017– 2022) have emphasized the need for doubling total food fish production by 2030, particularly in developing countries.

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.

Effect of dietary protein to energy ratio, stocking density and feeding level on performance of Nile tilapia in pond aquaculture

There is growing interest to understand the dietary P:E requirements for the supplemental feed used in tilapia pond culture where natural food contributes to production. In an on-farm trial, we tested the effect of lowering dietary P:E ratio on fish performance, pond nutrient utilization and economic benefit under two stocking densities and feeding levels.

New private GIFT hatchery in Timor-Leste boosts fish seed supply

In recent years, more and more rural households in Timor-Leste have taken up fish farming driven by increasing knowledge of a locally-tested and proven approach to growing fish and better access to quality genetically-improved farmed tilapia (GIFT) seed.

But with demand for GIFT seed continuing to outstrip supply, access to quality seed has remained a limiting factor.

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.

Tilapia major clinical signs (Arabic 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.
