Abstract: The study was conducted to evaluate minerals composition of Nile tilapia (Oreochromis niloticus) in wild environment (general Nile) compared with aquaculture environment, specifically in different types of ponds (concrete, polyethylene and earthen Ponds) in fish farms in Khartoum State. Also this work intended to determine and compare some physic-chemical parameters of water in the studied fish environment. Moreover, the study was conducted to compare some parameters according to source of water (Nile or wells). A total of 388 samples of Nile tilapia were collected from River Nile and governmental and private fish farms around Khartoum State and the samples were subjected to mineral analysis (Na, K, Ca, Fe, and P). Water samples were collected for water quality parameters (unionized ammonia NO3 -1 , sulphide H2S, temperature ºC, and pH). The findings of this study revealed that, Oreochromis niloticus from Nile environment has higher level of Na, K and P than from ponds and there was highly significant difference (P≤0.01), but there was no significant difference (P>0.05) for Ca and Fe. Fourty eight water samples were collected from River Nile and governmental and private fish farms around Khartoum State and subjected to physic-chemical analysis. There was a highly significant difference (P≤0.01) in all water quality parameters according to rearing site. However, when study Nile river water and wells water, H2S, temperature and pH showed no significant difference (P>0.05), while unionized ammonia showed significant difference (P≤0.05). Accordingly, the study concluded that Nile river water has a high water quality than other sources of water, also, River Nile aquaculture environment is an immediate environment in relation to ponds environment. The study recommended that more investigation in aquaculture and water quality parameters will provide knowledge and improve fish production.
