Final Technical Report of project R7284: Genetic Improvement and Utilisation of Indigenous Tilapia in Southern Africa.
The overall stated purpose of the Project was to develop a higher yielding genetically male tilapia (GMT) developed for improved livelihoods in small scale aquaculture in Southern Africa. Objectives were (i) to develop an assembly of accessions of up to 15 strains of O. mossambicus from throughout Southern Africa; (ii) to undertake genetic characterisation of available strains of O. mossambicus using molecular markers to identify, where possible, levels of genetic variability, population structure and stock/species specific markers; (iii) the adaptation and development of the YY male technology for production of genetically male tilapia (GMT) to strains of O. mossambicus; (iv) on-farm trials of GMT; (v) evaluation of potential social and economic impact of GMT production by small-scale farmers; (vi) to address the current demand for uptake of tilapia technologies, and in particular its extension to other regions of South Africa; and (vii) to initiate the process of developing a strategy/policy for the sustainable development of indigenous aquatic resources, for aquaculture development in the Southern African region.
