ES and ICE hastened <jats:italic>rigor mortis<\/jats:italic> onset and resolution (21 and 28\u2009h <jats:italic>post mortem<\/jats:italic>) compared to AN. This was confirmed by the faster ATP degradation in ES and ICE. Fillet shape features varied during <jats:italic>rigor mortis<\/jats:italic>, according to the stunning method, with the perimeter showing irreversible variation in ES and ICE groups. Initial circularity was recovered only in AN, while ICE and ES fillets showed significantly different values, between 0 and 192\u2009h.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>ES is a promising stunning technique for <jats:italic>S. carpio,<\/jats:italic> but parameters should be optimized<jats:styled-content>,<\/jats:styled-content> because of the adverse effect on muscle activity which caused a fast pH drop, and the presence of blood spots in the fillets. Further studies are needed to understand whether fillet shape changes can interfere with filleting or fillet processing and consumer appreciation. \u00a9 2022 Society of Chemical
