In this study, the abundance and distribution of anchovy Engraulis encrasicolus (Linnaeus, 1758) eggs and larvae in İzmir Bay were examined in 2013. For this aim, seasonally obtained the plankton samples from 11 stations identified in the bay. Anchovy eggs and larvae were obtained all seasons except winter. As a result, total 6889 eggs/m², 3231 larvae/m² were obtained. The minimum and maximum diameters of anchovy eggs; in short exis 0.49 to 0.56 mm (average 0.51±0.43), in long axist 1.09 to 1.30 mm (average 1.21±0.006). Minimum and maximum larvae length is 2.28-9.8 mm.

The aim of this study is to determine the stable isotope ratios of anchovy caught in the Black Sea and Marmara Sea. Stable carbon and nitrogen isotope ratios (δ13C, δ15N) of European anchovy (Engraulis encrasicolus) were estimated at four sampling sites (İğneada, İstanbul, Trabzon and Hopa) in the Black Sea and Marmara Sea (Turkey). δ13C and δ15N values of European anchovy ranged from -22.31 to -19.19 ‰ and from 3.81 to 12.79 ‰, while C/N ratios ranged from 2.01 to 6.21 in muscle tissue of European anchovy, respectively. İğneada station had more depleted δ13C values and more enriched δ15N values than other stations. This difference might be due to the terrestrial input and agricultural activities in this region.
