“…In this study, the plasma cortisol concentrations of the fish were significantly increased by thermal and salinity stresses (Figure 3), in agreement with previous data from a variety of teleosts, including olive flounder (Chang et al 2002;Davis 2004;Choi et al 2007). Therefore, a rapid change in water temperature or salinity generates stress in fish, primarily by activating the hypothalamus-pituitary-interrenal axis, resulting in the secretion of cortisol into the blood (Wendelaar Bonga 1997).…”

We isolated warm temperature acclimation-related protein 65-kDa (Wap65) cDNA from the liver of olive flounder and investigated the mRNA expression of Wap65 and HSP70 in olive flounder exposed to osmotic (17.5, 8.75, and 4 psu) and thermal stress (25 and 308C). The mRNA expression of Wap65 and HSP70 was increased by thermal stress. The mRNA expression of HSP70 was also increased by osmotic stress, whereas no significant change in Wap65 expression was detected. These results indicate that Wap65 mRNA expression occurs specifically in response to increases in water temperature, but not in response to osmotic stress. Plasma cortisol levels were also increased by osmotic and thermal stress. We also utilized the stress hormone cortisol to examine whether Wap65 expression is thermal-stress-specific. Cortisol treatment increased HSP70 mRNA expression in vitro, but had no significant effect on Wap65 mRNA expression. Thus, thermal stress, but not osmotic stress, induces Wap65 expression.

“…Therefore, it is thought that high water temperature stress increases levels of plasma cortisol and glucose by activating of hypothalamus-pituitary-interrenal axis. Also, in this study, the levels of cortisol and glucose in plasma were increased significantly during osmotic stress; these results agreed with the previous study (Chang et al, 2002). Therefore, it is suggested that osmotic stress also functions as a stressor in black porgy.…”

“…5). This has been reported in a variety of teleosts, including the flounder (Paralichthys olivaceus; Chang et al, 2002), sunshine bass (Morone chrysops Â Morone saxatilis; Davis, 2004), and black porgy (Choi et al, 2006(Choi et al, , 2007. The increase in plasma cortisol and glucose as water temperature increased suggests that high water temperature stress increases the plasma cortisol and glucose levels in black porgy.…”

We isolated the warm temperature acclimation-related protein 65-kDa (Wap65) cDNA from the liver of black porgy and investigated the expression by increasing water temperature in black porgy, Acanthopagrus schlegeli. Black porgy Wap65 full-length cDNA consists of 1,338 nucleotides, including an open reading frame, predicted to encode a protein of 425 amino acids and showed high homology to pufferfish (79%), Medaka (73%), carp (70%), and goldfish (68%) Wap65. Increase in water temperature (20 degrees C --> 30 degrees C; 1 degrees C/day) induced the rise of Wap65 mRNA expression in liver of black porgy. Also, the levels of cortisol and glucose in plasma were significantly higher at 30 degrees C than at 20 degrees C. To determine the high water temperature stressor specificity of the induction of Wap65, black porgy were transferred from seawater (SW) to freshwater (FW) for 24 hr. Wap65 expression was not detected when the fish were transferred from SW to FW (in fish transferred from SW to FW), although the levels of cortisol and glucose in plasma were increased. These results suggest that increase in Wap65 gene is related to high water temperature stress and play important roles in high water temperature environment of black porgy.

The purpose of this study was to obtain reference values of serum chemistry in Korean rockfish (Sebastes schlegeli), 5 juvenile (n=25) and 3 broodstock (n=15) subpopulations which were differentiated by cultured method. Serum samples were analyzed for the following commercial clinical kits: total protein, albumin, glucose, AST (aspartate aminotransferase), ALT (alanine aminotransferase), total cholesterol, free cholesterol, LDH (lactate dehydrogenase) and ALP (alkaline phosphatase). Significant differences were observed in the values of total protein, albumin, total cholesterol, AST, ALT, LDH and ALP between juvenile and broodstock subpopulations. In the comparison of total protein, albumin, total cholesterol and ALP, broodstock subpopulations showed higher levels. On the other hand, increased AST, ALT and LDH were observed in juvenile subpopulations. These results indicate that cultured method are major contributors to health-related physiology of Korean rockfish, juveniles and broodstocks.
