초록

This study was conducted to investigate the effects of different water temperatures (8, 11, 14 and 17°C) on growth, survival and hematological parameters of juvenile chum salmon (Oncorhynchus keta) for eight weeks. At the end of the experiment, at 14°C, the final body weights of the O. keta group were the highest compared to the other groups. Also, the O. keta showed a higher tendency in the 14°C group than the 8, 11, and 17°C groups in terms of growth performances, including specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency (FE), weight gain (WG), and condition factor (CF). The survival rate (SR) was 100% at 8 and 11°C groups, 96% at 14°C group and 98% at 17°C group. In the plasma components, the alanine aminotransferase (ALT) was significantly decreased at 17°C group, whereas there was no significant change in the albumin (ALB), total protein (TP), sodium (Na+), potassium (K+) and chloride (Cl-) levels. Among the whole-body composition of salmon, moisture, crude protein, and ash were not significantly affected by water temperature. However, crude lipid in the 8°C group was significantly higher than in other water temperature groups. The results of this study demonstrated that the optimal temperature to stable growth performance for juvenile O. keta was 14°C.
