The Effect of Fish Size, Age and Condition Factor on the Contents of Seven Essential Elements in Anguilla anguilla from Tersakan Stream Mugla (Turkey)

Cahit Kasimoglu

The correlation coefficients between age, weight, total length and condition factor (K) and trace metals (Co, Cr, Cu, Fe, Mn, Ni and Zn) in Anguilla anguilla were determined. Totally 160 fish samples were collected from Tersakan Stream (Mugla) between September 2011 and August 2012. Highly significant (P<0.01) relationship between trace metal concentrations in fish muscle and age, weight, total length and condition factor (K) was found. Significantly positive relationship among trace metals (Co, Cr, Cu, Fe, Mn, Ni and Zn) and fish age, weight and total length was observed, while all trace metal concentrations were negatively correlated with fish condition factor (K). The comparison of trace metal concentrations in the muscle of Anguilla anguilla with the tolerable values indicated that the trace metal concentrations in muscle tissue did not exceed the WHO/FAO, EPA and IAEA–407 guidelines.
