초록
In this study, clinically healthy Korean rockfish were provided by a farm and then raised in a lab for 14 days at three different temperatures (10°C, 15°C, and 20°C) to establish hematological, blood biochemical, and histopathological reference intervals against normal fish. Hematocrit, MCV, MCHC, total protein, BUN, and GPT values in the blood showed significant differences among temper- ature groups. As the water temperature increased, neutrophil, thrombocyte, and lymphocyte counts also rose, while the monocyte value peaked at 15°C. The histopathological score revealed significant variations in the gills, stomach, and inflammation indices by temperature group; the gills and in- flammation indices peaked at 20°C, whereas the stomach index peaked at 15°C. It is expected that information on these normal values will serve as a fundamental collection of data for further studies related to laboratory-based experiments.
Abstract
In this study, clinically healthy Korean rockfish were provided by a farm and then raised in a lab for 14 days at three different temperatures (10°C, 15°C, and 20°C) to establish hematological, blood biochemical, and histopathological reference intervals against normal fish. Hematocrit, MCV, MCHC, total protein, BUN, and GPT values in the blood showed significant differences among temper- ature groups. As the water temperature increased, neutrophil, thrombocyte, and lymphocyte counts also rose, while the monocyte value peaked at 15°C. The histopathological score revealed significant variations in the gills, stomach, and inflammation indices by temperature group; the gills and in- flammation indices peaked at 20°C, whereas the stomach index peaked at 15°C. It is expected that information on these normal values will serve as a fundamental collection of data for further studies related to laboratory-based experiments.
