Biometrics Characters, Length-Weight Relationships and Genetic Properties of Damselfish, Chromis chromis (Linnaeus, 1758) (Osteichthyes: Pomacentridae) from the Black Sea

The damselfish Chromis chromis is typically the most common fish species in rocky shores of Mediterranean Sea and Black Sea. Despite having no commercial value, C. was considered as a key for littoral environment. In this study, biometric properties length-weight relationships were examined 112 specimens sampled from 2018. Fifteen morphometric six meristic characteristics measured. We also used molecular approach employing mitochondrial genes (16S rRNA COI) first time to further characterize collected Morphometric characters male female similar there differences between sexes. average length weight calculated 99.54 + 11.49 mm (72.0-115.1) 18.35 5.95 g (5.96-26.56), respectively. relationship W = 0.0127TL3.117 (R2 0.834) growth indicates positive allometric (b>3). 16S COI partial sequences analysis indicated close genetic with Aegean
