Abstract This paper used choice experiment to assess households preferences for wastewater fed fish in Lima, Peru. The study considered four fish attributes, price, source, certification and information on additives. In total, 443 households participated in the field experiment. Results from the estimation of the random parameter logit (RPL) model in both the willingness to pay (WTP) and preference space showed that in general, households expressed positive preferences for fish raised in wastewater, freshwater and wild fish as well as certification and use of additives. Our findings show that household WTP for fish raised in the wild and in freshwater were positive and more robust as compared to WTP for wastewater fed fish which was influenced by factors such as certification. We find that households are willing to pay premiums of $0.69, $1.06 and $2.98 for wastewater, freshwater and wild fish respectively. We also find evidence to suggest that health and food safety concerns are the most important consideration in household preferences for wastewater fed fish amongst a set of perceptions variables examined in this study.
