This study was conducted to determine the effect of starvation on the hematological characteristics, and the contents of chemical components and activities of enzymes in blood serum of red sea bream, Ckrysopkrys major. Wild fish were starved after the net fishing for 90 days at 13318℃. At each fixed day (0, 1. 2, 4. 9, 15, 30, 70 and 90th day), ten fish were presented for the hematological examinations and the biochemical analyses of blood serum. Hemoglobin content, hematocrit value, red blood cell count, and specific gravity of the whole blood increased early in the starving period and then decreased, and the fish exhibited a serious anemia. From the mean corpuscular constants (MCH. MCV and MCHC), the anemia was categorized as the hyperchromic microcytic type. Furthermore, it should be noted that the anemia was accompanied by the disappearance of immature erythrocytes. The contents of total protein and total cholesterol, and the activity of LAP in serum, also increased early in the starving period and greatly decreased later. BUN in serum was stable at a high level for some time after the abrupt increase, and decreased thereafter. The activities of GOT, GPT, and LDH in serum did not change till the 30th day, before the remarkable increase set in. Though the changes of the contents of glucose and total bilirubin, and the ALP activity in serum were recognized during the starvation, those levels were within the normal range.
