Zusammenfassung: | This study was conducted to investigate the effects of elevated water temperature (WT) on biochemical and immunological factors in the hemolymph of the abalones, Haliotis discus hannai and H. discus discus. The abalone were exposed to various WT; 20, 22, 24, 26 and $28^{\circ}C$ for 4 days. In the control and $20^{\circ}C$, total-protein (TP), glucose and calcium (Ca) in hemolymph of H. discus discus were higher than the values in H. discus hannai. The values of magnesium (Mg), alkaline phosphatase (ALP) and lysozyme in H. discus hannai were similar to the H. discus discus in the control. There were no significant alterations in TP, glucose and Mg levels of hemolymph in H. discus hannai and H. discus discus by WT increases. The values of Ca, ALP and lysozyme were increased in H. discus hannai exposed to the high temperature (26 and $28^{\circ}C$) compared to control, while the values in H. discus discus were not significant difference between the WT groups. The phenoloxidase (PO) activity was increased in hemolymph of H. discus hannai exposed to high temperature (${\geq}24^{\circ}C$) compared to the control (P < 0.05). These physiological and immunological parameters were significantly changed in H. discus hannai. However, these parameters in H. discus discus were barely altered at the high WT (P < 0.05). These results suggested that H. discus hannai is considered to be more sensitive than H. discus discus at the high WT. 본 연구에서는 수온 증가에 따른 북방전복 (Haliotis discus hannai) 과 둥근전복 (H. discus discus) hemolymph의 생리 및 면역학적 변화를 관찰하기 위하여 위 두 종을 20, 22, 24, 26 및 $28^{\circ}C$ 수온에 각각 4 일간 노출시켰다. 노출 결과, hemolymph의 total-protein (TP), glucose, 칼슘 (Ca) 은 둥근전복이 북방전복보다 높은 값을 보였으나, 마그네슘 (Mg), alkaline phosphatase (ALP) 및 lysozyme은 두 종에서 유사한 값을 보였다. 수온 증가에 따른 hemolymph의 TP, glucose 및 마그네슘은 두 전복 모두에서 유의한 변화가 관찰되지 않았다. 그러나 칼슘과 면역관련 인자인 ALP 및 lysozyme은 둥근전복에서 유의한 차이가 없었으나, 북방전복에서는 $26^{\circ}C$ 또는 $28^{\circ}C$의 고수온에 노출되었을 때, 유의하게 높은 활성을 보였다. 한편 phenoloxidase (PO)는 북방전복에서 높은 값을 보였으며, 수온이 높을수록 증가하는 경향을 보였다. 결론적으로 북방전복은 둥근전복과 달리 여러 지표에서 유의한 변화가 관찰된 것으로 보아 북방전복이 둥근전복보다 고수온에 보다 민감한 것으로 사료된다. |
