Abstract:
This experiment was conducted to investigate the
differences in proximate and mineral compositions between hatchery reared
and wild caught yellowtail Seriola quinqueradiata juveniles. The body
excluding the stomach, intestine and pyloric cecum of 58- and 70-day-old
juveniles produced at Nagasaki Prefectural Institute of Fisheries in 1999
and those of juveniles caught from the coastal area of Kagoshima Prefecture
in 1998 and Nagasaki Prefecture in 1999 were analyzed.The crude lipid
contents were higher in reared fish than the wild ones. On the other hand,
the amount of crude protein in the wild fish was higher compared to the
reared ones. Furthermore, the amount of calcium, magnesium, iron, zinc, and
copper were different in the two types of fish. These nutritional elements
could be important factors in health of the yellowtail juvenile.
