The first phase of the project, “Demand for seafood safety and environmental sustainability certification standards in sub-Saharan Africa: the case of Nigeria”, was implemented by WorldFish Center in collaboration with three other partners in eight states in Nigeria from August to November 2019. The willingness to pay experiments were conducted from October to November 2019. The objective was to evaluate demand for aquaculture certification and to examine the effect of expectations-based reference points on willingness to pay for aquaculture certification. The incentive-compatible experiments were conducted with consumers at the points of purchase of fish. A post-experiment survey was then administered to the participants of the experiments to collect demographic, knowledge, and other data required as additional covariates in the assessment of consumers’ willingness to pay for aquaculture certification.
