The blood NAD(H) level varies with animal species, whereas the blood NADP(H) concentration is the same in all animal species. Because little is known about the blood NAD(H) and NADP(H) concentrations in water animals, we investigated the concentrations of both in nigorobuna, Carassius auratus grandoculis. Fifty nigorobuna (0+years old) were harvested from Lake Biwa, Seventeen of them were aquacultured and then released into the lake, 9 of them were transferred to a paddy field for one or two months after hatching and then released into the lake, and 24 of them were born and grew up in the natural environment. The blood NAD(H) concentration in nigorobuna was approximately 80nmol/mL, which is almost the same as that of rats and 2.5 times higher than that of humans. The blood NADP(H) concentration in nigorobuna was approximately 2.5nmol/mL, which is one fourth of the values in rats and humans. There were no differences in blood NAD(H) and NADP(H) levels by sex or life history in nigorobuna.
