title: Blood physiological responses and growth of juvenile starry flounder, Platichthys stellatus exposed to different salinities.
abstract: Blood physiological responses, growth and survial rates were examined in juvenile starry flounder, Plotichthys stellatus exposed to different salinities (5, 10, 20, 33 ppt) for 90 days. At the end of the experiment, the plasma levels of Na+and osmolality were similar at 10, 20, 33 ppt, however, the values were significantly lower at 5 ppt compared to those at other salinities. Stress responses such as plasma levels of cortisol, glucose, hematocrit (Ht) and hemoglobin (Hb) levels in all groups showed no significant difference. Although no differences in growth were observed, body weight at 20 ppt tended to be higher than others. Survival in all groups was greater than 99% with no significant differences. These results suggest that starry flounder is euryhalin species, thus this fish can be reared with normal growth and survival rate at 5-33 ppt salinity without osmoregulatory disturbance and stress.
