The decrease in the availability of fishmeal and fish oil prompted the research group involved in the SUSHIN project to consider more sustainable formulations for aquaculture feeds. Among all the alternative formulations, SUSHIN also investigated experimental feeds in which the traditional fish meal was replaced by insects. The preliminary results appeared to be encouraging, from both a nutritional and an eco-friendly point of view. Indeed, the use of a very powerful analysis tool, the Life Cycle Assessment (LCA), allowed to quantify the impacts caused to the natural environment by the whole insect productive chain and proved the insects to have better performances than many protein alternatives sold on the market today. Despite the benefits, consumers in the Western countries are still skeptical about the actual quality of fish raised with aquafeed which contains insect proteins rather than traditional protein sources. Therefore, an analysis of the consumers’ penchant for fish raised with these alternative feeds was included among the objectives of this project. The interview analysis focused on young Italians, consumers of the future. Today, the first results of the survey will be presented.
