The composition of fish lipids is generally related to the species of fish, environmental temperature, season, physical and chemical properties of the water, age, sex, rearing conditions, physical activity and diets [11]. If the fat content of foods has a great influence on the fatty deposits, the type of fat ingested does not appear to have any effect on the extent of the deposits but on the fatty acid composition of body lipids [3]. numerous studies have shown that the fatty acid composition of tissues reflected those of dietary lipids [12,13]. The fatty acid composition of fish flesh is strongly modified by the type of dietary lipid sources[14-18]. Rainbow trouts are members of Salmonidae family. it is also widely used as a farmed fish in many countries because of its rapid growth and high value as a food.

Following the exponential increase in Africa's population compared to past decades and the increased need for food production to meet this growing demand in the continent, studies on agricultural research for sustainable food production have been gradually strengthened in the face of climate change, water scarcity and increasing desertification. Aquaculture is a growing sector in Africa and has a major role to play in the role is of primary importance in ensuring food security, while reducing dependence on wild fish stocks that are often overexploited. However, this rapid growth poses challenges to the overall longterm sustainability of the agricultural sector and raises concerns in a number of respects. Sustainable aquaculture implies the integration of all three pillars or dimensions of sustainable development to ensure that this young African industry is economically and environmentally viable, but also that aquaculture farms operate in a socially responsible manner.
