FISH made significant progress during 2018 in producing and disseminating a suite of research innovations for the sustainable development of fisheries and aquaculture across Africa, Asia and the Pacific.
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.
This annual report provides key results and learning achieved during 2018 in the CGIAR Research Program on Fish Agri-Food Systems (FISH). FISH made significant progress during the year in (a) producing and disseminating a suite of research innovations for sustainable development of aquaculture and fisheries across Africa, Asia and the Pacific, and (b) in moving toward stronger results-based program management through development and adoption of a monitoring, evaluation and learning platform.
Fish feeds containing little to no wild-caught fish combined with a novel feed ingredient has the potential to greatly increase the growth of farmed tilapia, finds a new study by WorldFish and the Commonwealth Scientific and Industrial Research Organization (CSIRO).
Tilapia Better Management Practices (BMP) Workshop
Tilapia is the world’s second most important farmed fish after carp and its global production now standings close to 7.0 million tonnes and valued at over USD 9.8B.
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.
Since 1989, WorldFish has been working with the Bangladesh Government and development partners to create a more productive fisheries and aquaculture sector that contributes to diversified and resilient rural livelihoods and promotes food and nutrition security.
The development of genomic markers is described for Nile tilapia, Oreochromis niloticus, using the Diversity Arrays Technology (DArT) genotype-by-sequencing platform. A total of 13 215 single nucleotide polymorphism (SNP) markers and 12 490 silicoDArT (dominant) markers were identified from broodstock of two selective breeding programs [Genetically Improved Farmed Tilapia (GIFT) strain from Malaysia and the Abbassa strain from Egypt]. Over 10 000 SNPs were polymorphic in either strain, and 2985 and 3087 showed strain-specific polymorphisms for the GIFT and Abbassa strains respectively.
The CGIAR Research Program on Fish Agri-Food Systems (FISH) is a new CRP that builds on earlier CRPs for Livestock and Fish (L&F) and Aquatic Agricultural Systems (AAS) as well as prior research by WorldFish and the managing partners. Key outcomes from the two flagships of Sustainable Aquaculture and Sustaining Small-scale Fisheries during 2017, including milestones achieved, are summarized in this report.
