Abstract
The samples of cultured flounder (Paralichtys olivaceus) were collected from Tongyeong and Yosu in Korea and Nagasaki in Japan and processed to analyses of body and serum. Body size and weight were not significantly different between Korea and Japan produced. But the body weight of average size of flounder produced from Nagasaki was the highest from the samples. The average of fish body was not significantly different from the samples. The water content of fish body was lower in samples from Nagasaki and fat content was higher in the samples from Nagasaki and followed by Yosu and Tongyeong. The percentage of body water, fat and protein contents was Nagasaki, Yosu and Tongyeong in the order of high values. Japanese flounder showed relatively high content of body fat and muscle. The cholesterol of serum was highest in the samples of Yosu. The triglyceride of serum was highest in the samples of Nagasaki. Lipoprotein was highest in the samples of Nagasaki and enriched fat content in LDL fraction.
