Popis: Laboratory-reared king salmon were harvested using CO 2 anesthetizing (CO 2 ) or by rested harvesting techniques using AQUI-S anesthetizing (AQUI-S). Fish were killed by spiking, and flesh portions were stored in air packs (0 °C) for 22 d, Headspace oxygen levels, sensory characteristics (raw and cooked), tensile properties, drip loss, gaping, pH, nucleotide derivatives, color, and bacterial counts were determined after 5 to 22 d of storage. All parameters except tensile properties showed significant trends with storage time. Oxygen levels were consistently lower in CO 2 packs whereas, on average, drip was lower in AQUI-S samples, and L*-values and bacterial numbers were higher in AQUI-S samples. Overall, harvesting effects had minimal impact on the quality parameters measured.
