Abstract

This study investigated physiological and hematological changes, expression of stress protein Hsp70 mRNA and oxygen consumption in olive flounder (Paralichthys olivaceus) after exposing the fish at different temperature conditions (9, 12, 15, 18 and 21℃) for 24 and 48 hours. Hematological parameters including hematocrit (Ht) and hemoglobin (Hb), cortisol and glucose, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), NH3, osmolality and total protein (TP) mostly exhibited significant changes at 9 and 12℃. The expression of Hsp70 mRNA was also higher at 9 and 12℃ than at other temperatures. The measured oxygen consumptions were also lower at 9 and 12℃ than at 21℃. It is expected that the study results could be utilized as baseline data to control water temperature during long-distance transportation, e.g. for exporting olive flounder juveniles to overseas. 급격한 수온의 변화는 어류의 생리학적인 측면에서 스트레스를 유발한다. 본 연구에서는 넙치 (Paralichthys olivaceus)로부터 각 수온별(9, 12, 15, 18 및 21℃) 조건에 따라 24 및 48시간 동 안 노출시킨 후에, 혈액생리학적 분석, 스트레스 단백질로 알려진 Hsp70 mRNA 발현 및 산소 소비량을 조사하였다. 혈액학적 분석에서 hematocrit (Ht) 및 hemoglobin (Hb), 혈장 코티졸 및 글루코스의 변화, aspartate aminotransferase (AST) 및 alanine aminotransferase (ALT), NH3, 삼 투질농도(osmolality) 및 총단백질(total protein, TP)은 9℃ 및 12℃에서 다른 수온별 실험구에 비 해 대부분의 항목에서 유의적인 차이를 보였다. Hsp70 mRNA 발현은 9℃ 및 12℃에서 다른 실험구에 비해 높은 발현량을 확인하였고, 산소소비량은 9℃ 및 12℃에서 21℃에 비해 낮았다. 이러한 결과는 넙치 종자의 장거리 수송을 위한 수온자료로 활용할 수 있다.
