Annular seabream - Diplodus annularis (Linnaeus, 1758) is an important object of the coastal and recreational fishing, playing an important role in biodiversity and sustainability of coastal marine ecosystems of the Crimea. Morphological parameters of D. annularis in the modern period were investigated. The peculiarities of the size composition of annular seabream, depending on gender (female, male, hermaphrodite, juveniles) and on age (from 0+ to 6+ years old) were shown. The comparative analysis of the most numerous age groups showed that juveniles aged 0+...1 were significantly smaller than the individuals of the same age, but with matured gonads of females or males. Hermaphrodites have maximal condition factor. Length-weight relationship is W = 0.009L3.230, hence the weight of fish increases positively allometrically with increasing length of specimens. Comparison of our data with the morphological fish parameters from other parts of the range of its habitat (Mediterranean Sea, the east coast of the Atlantic Ocean) confirms the previous data on high-speed growth of this species in coastal waters of the Crimea due to good food base and a lack of competitors - other Sparidae . Sex ratio of D. annularis of different age groups is not the same. More than half of the fish in the age of 0+…1 year old are represented by immature individuals and even less by males. The percentage of females and hermaphrodites increases among older fish. The oldest fish are often presented by females (59-64 %).
