The red king crab (RKC, Paralithodes camtschaticus) is a highly-valued decapod species of key importance for the economy of the northern Norwegian coastal region. Nearly the entire harvested volume (1727 t in 2019) is exported to high-end markets, mostly as live crabs, although RKC can also be processed into two sections (i.e., clusters) commercialized as a frozen or ready-to-eat product under refrigeration. The fact that the Norwegian RKC fishery is a year-round activity constitutes an advantage over competing RKC fisheries, which are inactive during the winter and the spring. Nonetheless, this also involves the commercialization of RKC harvested between March and May, when its quality is considered poorer due to the physiological changes related to molting. This study aimed to acquire quantitative information on the seasonal quality variation of RKC by comparatively evaluating the quality attributes of spring and autumn harvests, which are, respectively, associated predominantly with a postmolt and intermolt population. Specifically, in the processed clusters obtained from spring postmolt RKCs, it was observed significantly (p
