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℃, 15℃, and 20℃) 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 temperature groups. As the water temperature increased, neutrophil, thrombocyte, and lymphocyte counts also rose, while the monocyte value peaked at 15℃. The histopathological score revealed significant variations in the gills, stomach, and inflammation indices by temperature group; the gills and inflammation indices peaked at 20℃, whereas the stomach index peaked at 15℃. 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.
