Rainbow trout is one of the most spread non-native breeds at world level, being originally both from Asia and also from North America. Growing rhythm of these breeds is net superior to other trout breeds from Romania, reaching at the age of four years a weight of 400-500 g. In growing and development of ishes, environmental conditions plays a very important role, because in aquatic environment could be founded different substances necessary for a normal growing and development of organisms.

Trout meat contains important quantities of minerals, which are essential for human health, those ones being in luenced by a series of factors such as: breed, season, age and nutrition. From this point of view the current paper aimed to highlight the way in which quality of administered feed in luence the content of trout muscles in minerals. Biological material was represented by a number of 30 rainbow trout individuals of three different ages. Quantitative determinations for calcium, zinc, sodium and magnesium were realized using an atomic absorption spectrophotometer and determination of phosphorous from trout meat was realized using a spectrophotometer. At the end of research from those ive analyzed minerals, the greatest values were founded in case of phosphorous (P) which were between 110.46 and 225.40 mg/kg -1 , on the last rank being placed zinc (Zn) with mean values which varied from 0.74 to 0.99 mg/kg -1 .
