Abstract

Despite the growing potential of cobia (Rachycentron canadum) for aquaculture, when it comes to processing of this fish species, knowledge of various aspects of the production chain is still scarce. The objective of this study was to evaluate the performance of steak and waste filleting of wild and cultivated cobia, considering the performance of the viscera (RVI), head income (RCA), carcass yield without the head (RCR), whole fillet yield skinless (RFI), skin with scales income (PPE) and yield of the belly (PBA). Twelve samples of cobia were used, with an average weight of 2,435g. Six wild animals were purchased at local fish market in the municipality of Itarema, Ceará State, Brazil, and the other 06 cultivated obtained from Buzios Mariculture Farm, located in Ilhabela, São Paulo State, Brazil. The fish were gutted, beheaded and filleted manually. The results obtained allowed to conclude that there were no significant differences for the fillet yield, guts, head and skin of the wild and cultivated cobia. However, significant differences for carcass and belly cut yield were observed.
