Changes in hematological parameters and heat shock proteins in juvenile sablefish, Anoplopoma fimbria depending on water temperature stress.

Juvenile sablefish, Anoplopoma fimbria, of length 15.3±1.6 cm and weight 68.4±4.6 g were used to assess the effects of water temperature (8, 10, 12, 14, 16, 18, and 20 °C) on hematological parameters and heat shock proteins (70 and 90) for 4 months. The hematological parameters such as red blood cell count, hematocrit, and hemoglobin were significantly decreased at 18 °C. The inorganic plasma components such as calcium and magnesium were not altered by water temperature. The organic plasma components glucose and cholesterol were notably elevated at 18 °C, whereas total protein was reduced. The enzymatic components such as aspartate aminotransferase (AST), alanine aminotransminase (ALT), and alkaline phosphatase (ALP) were notably elevated at 16 or 18 °C. The results of this study indicate that a temperature higher than the proper temperature affects the hematological parameters and heat shock proteins of juvenile sablefish, A. fimbria.
