COMPARISON OF ESSENTIAL TRACE ELEMENT PROFILES OF RAINBOW TROUT FISH (ONCORHYNCHUS MYKISS) MEAT AND EGG

Many mineral compounds, present in fish meat, are essential for human life at low concentrations. Humans need a steady supply of at least minerals to maintain health and optimal performance. The elements such as Fe, Cu, Mn and Zn are essential elements because of their crucial role in biological systems. In this study, essential element profiles of rainbow trout meat and its egg were investigated and compared each other. Higher concentrations of essential trace elements (Fe, Cu, Mn and Zn) were found in egg of rainbow trout compared to its meat. Highest Zn (140.28 +/- 4.24 mu g/g) content was determined in trout egg samples compared to other trace elements. Fe (48.17 +/- 1.61 mu g/g) was the most abundant trace elements found in trout meat, whereas Mn (1.24 +/- 0.04 mu g/g) was the least.
