Evaluation of Morphological and Quality Parameters in Adult Male Red King Crabs (Paralithodes camtschaticus) Raised to Commercial Weight from Juveniles

Red king crab (RKC) has become a valuable resource, and most of this fishery operates in quota-regulated area (QRA) east 26°E. West the QRA, free (FFA) is established to limit further migration. Today, juvenile RKCs from FFA are not utilized. This study investigated morphological quality parameters adult (≥800 g) after live holding (LH) 23 months starting juveniles (on average 500 g). During LH, were kept two separate tanks, one at ambient seawater temperature (AST) elevated (AST-E). The fed ad libitum. Both tanks divided into sections, with sand tray. After months, processed analyzed. hepatosomatic index, abdomen meat content, cluster yield, moisture, whiteness instrumental chewiness differed significantly ( P < 0.05 ) between wild or both LH groups. availability indicated improved habitat conditions as several positively affected. Also, lower variation morphology muscle was observed subgroups access than those without sand.
