160 random samples of natural Tilapia nilotica (NT), farmed Tilapia
nilotica (FT), natural Mugil cephalus (NM) and farmed Mugil
cephalus (FM) (40 of each) were collected from eight fish farms and
Alborolos lake in Kafr El-sheikh governorate through 12 months.
The collected samples were subjected to chemical examinations
to evaluate the effect of rearing conditions and fish types on
nutritional value and quality of the examined fish. The study revealed
that the farming rearing conditions leads to a significant higher
fat and protein percent in farmed fish than natural fish while the
Mugil cephalus species were higher than tilapia nilotica in fat and
protein percent.
