Comparison between Otoliths and Length Based Ageing and Growth of African Armoured Searobin (Peristedion cataphractum L. 1758; Teleostei, Peristediidae)‎ off the Southern Coasts of Sicily (Mediterranean Sea)‎

الملخص EN

The recovering of Peristedion cataphractum otoliths collected between 1991 and 1992 from specimens sampled off the southern coasts of Sicily has allowed a direct ageing and growth estimation to be compared with the length based method estimates produced in successive years.

Overall, 855 left otoliths (sagittae) were recovered, measured, and read as a whole surface.

The core and rings distances were also measured to perform back-calculation.

The otolith length-body length relationships were allometric.

Back-calculated lengths at age were in agreement with the lengths estimated with otolith readings.

Present results showed a good congruency between otoliths and length based method.
