Abstract

The sharpsnout seabream (Diploduspuntazzo, Cetti 1777) is a species rarely foundin coastal areas of Sicily, but is importantin Mediterranean aquaculture. In order to detectthe number of meristic characters andthe main types of body deformation, 588 specimensof sharpsnout seabream were collectedfrom a coastal zone of south-east Sicily (Licata,AG—Italy). Different sized classes were examinedand the relationship between size and thenumber of meristic characters (number of finrays) was found. The number of vertebrae, analfin hard rays and dorsal fin hard rays wasconstant and did not vary with size. Seventeentypes of skeletal and fin anomalies wereobserved, but no grave anomalies were found,such as the absence of a swimbladder, lordosis,kyphosis and calculi in the terminal tract ofthe urinary duct. The most prevalent anomalieswere associated with the fins, especiallyE7 (pectoral fin rays), F7 (anal fin rays) andI7 (dorsal fin soft rays). There was no correlation between frequency of anomaly and sizeclass. The malformation index was 4.54.
