벤자리(Parapristipoma trilineatum)의 혈액 생리학적 변화에 미치는 수온 스트레스의 영향

Abstract

In this study, we investigated the physical effect of water temperature change by water temperature stress in blood of chicken grunt (Parapristipoma trilineatum). Result of growth at high temperature was highest at 4.8% in 30℃ group. Blood biochemical changes showed high levels of AST and ALT at high temperature, suggesting that hepatic damage was induced by high temperature. Total protein(TP) was significantly higher in 30℃ group than other groups. Triglyceride(TG) showed at lower temperature of 15℃ and 25℃, higher than control 20℃, and higher than 30℃, respectively. Glucose were 93 ± 23.33 mq/dL at 15℃, 85 ± 27.99 mq/dL at 20℃, 79.8 ± 24.97 mq/dL at 25℃ and 99.5 ± 3.53 mq/dL at 30℃, respectively. Ca2 + were 12.42 ± 2.85 mq/dL at 15℃, 12.92 ± 0.77 mq/dL at 20℃, 12.4 ± 1.20 mq/dL at 25℃ and 15.85 ± 0.21 mq/dL at 30℃. This result was significant difference in 30℃ group. Lysozyme activity tended to decrease with increasing water temperature and no significant difference between individuals. Result of lysozyme, which is the most innate immunity, according to increasing of water temperature PO activity is increased rather than decreased. The osmolality results were 414.2 ± 22.43 mOsm/ℓ at 20℃ and 429.8 ± 34.92 mOsm/ℓ and 433.8 ± 34.92 mOsm/ℓ at 15℃ and 25℃ respectively and 412.8 ± 18.39 mOsm/ℓ. at 30℃ It was observed that no significant between control 20℃ in all experiment groups.
