Fish otoliths are inert aragonite structures characterized with metabolic changes depending on physical and chemical
properties of the environment. An otolith grows with elements and components in the environment which layers up on
each other on the growth layer. The growth starts as a spawn and continues throughout maturation and until death and
thus all life properties of a fish are recorded. Besides, otoliths of the fish might give some ideas about the environment
where the fish lived. Thus, it becomes a potential tool for obtaining chronological records of the environment where the
fish lived. This research was investigated from April to May 2013 in Iskenderun Bay. Macro and micro elements (Na, K,
Li and Ca) were evaluated for Barracuda with four different age stages. As a result of this study, content of Na of the four
different age stages of otoliths did not changed as much as all other elements investigated in this present study.
Additionally, Ca levels of the otoliths were increased with the age whereas K and Li contents were decreased.
