Determination of the Element Values of Rainbow Trout (Oncorhynchus mykiss Walbaum, 1792) Eggs

Abstract

The objective of this study was to determine the amount of the elements of rainbow trout (Oncorhynchus mykiss Walbaum, 1792) eggs obtained from different. stations. The study was conducted in 5 different production areas that are producing the most rainbow trout eggs in Turkey. Element analysis (Na, Mg. Al. P, K, Ca, Cr, Mn, Fe, Co, Ni, Zn. As, Se. Cd. Ba, Pb, Hg. and Cu) of rainbow trout eggs were performed using ICP-MS (Inductively Coupled Plasma- Mass Spectrometer). At the end of the study. it, was determined that the daily consumption limit for selected elements (Ca. P. Mg, Zn, Mn, Ni and Se) was not exceeded in individuals consuming 100g of rainbow trout eggs per day. The daily intake recommended by the European Communities Commission was determined to be sufficient for the K, Ca, P, Mg, Fe, Zn, Cu and Mn elements in rainbow trout eggs. The Cd and Pb values of rainbow trout eggs obtained from different stations were determined significantly less than the values included in the Turkish Food Codex. The results of this study were thought to be important for both consumers and juvenile rainbow trout producers.
