Performance assessment of GIFT strains in Bangladesh

The survey was implemented to assess on-farm performance of the genetically improved farmed tilapia in Bangladesh. The primary sampling unit was tilapia aquaculture producers. The survey comprised the following modules: (1) farmer characteristics; (2) aquaculture production and marketing activities including input use and cost as well as output harvested and sold; (3) social networks; (4) access to information and financial services; (5) participation in farmer groups; and (6) risk preference and behaviour; and (7) assets ownership. Data on aquaculture production were collected at pond level. The survey captured detailed data about all types of polyculture systems allowing for a characterization of farming systems.
