Description
Summary: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.
