THE FIRST REPORT OF ABNORMAL AGE RINGS IN OTOLITHS LAPILLUS OF ARIIDS CATFISH
The present work aimed to record the first presence of abnormal age rings in Cathorops spixii lapillus otoliths from Cananeia-Iguape Estuarine-Lagoon Complex (CIELC), Southern region of Brazilian coast. In August 2018, 59 specimens of C. spixii (Siluriformes, Ariidae) were collected during one station sampling in the northern (n = 25) and another in the southern sector (n = 33) of CIELC. In general, among the otoliths that presented age ring alterations, this divergent zone was observed in opaque and translucent layers, on the right side, between the fifth and seventh age rings.
