Abstract

Otoliths are calcium carbonate (CaCO3) accumulations. Under the influence of different ecosystems morphological and chemical composition change. In this study, economically important two demersal fish species; European hake Merluccius merluccius (Linnaeus, 1758) and Stripet red mullet (Mullus surmuletus Linnaeus, 1758) was examined. Otoliths (Sagitta) belonging to these two species have been studied both chemically and morphologicall. Morphometric measurements of otoliths (length, mm; width, mm; area, mm2; perimeter, mm) in the sagittal of each species was made by the Leica M125 tri-ocular microscope. In the chemical analysis of otoliths, strontium (Sr), magnesium (Mg) and calcium (Ca) trace element amounts, the ratios of Sr and Mg trace elements to Ca element (Sr/Ca and Mg/Ca) were determined. For the micro-chemical analysis of otoliths ICP-MS was used. The highest magnesium (24.92±9.57 mmol/mol) and strontium (26.17±1.81 mmol/mol) element values were found in the otolith of red mullet. The difference between strontium (Sr) and magnesium (Mg) amounts for two fish species was found to be significant (P

Özet

Otolitler kalsiyum karbonat (CaCO3) birikimleridir. Farklı ekosistemlerin etkisi altında morfolojik ve kimyasal olarak değişmektedir. Bu çalışmada, ekonomik olarak önemli iki demersal balık türü; Bakalyaro Merluccius merluccius (Linnaeus, 1758) ve tekir (Mullus surmuletus Linnaeus, 1758) balığına ait otolitler (Sagitta) hem kimyasal hem de morfolojik olarak incelenmiştir. Otolitlerin (uzunluk, mm; genişlik, mm; alan, mm2; çevre, mm) morfometrik ölçümleri Leica M125 tri-oküler mikroskop ile yapılmıştır. Otolit yapısındaki stronsiyum (Sr), magnezyum (Mg) ve kalsiyum (Ca) iz element miktarları ile Sr ve Mg eser elementlerinin Ca elementine (Sr/Ca ve Mg/Ca) oranları belirlenmiştir. Otolitlerin mikro kimyasal analizi için ICP-MS kullanılmıştır. En yüksek magnezyum (24,92±9,57 mmol/mol) ve stronsiyum (26,17±1,81 mmol/mol) element değerleri tekir otolitinde tespit edilmiştir. İki balık türü için stronsiyum (Sr) ve magnezyum (Mg) miktarları arasındaki fark önemli bulunmuştur (P
