The age and growth of the sand sole Pegusa lascaris from the Canarian Archipelago were studied from 2107 fish collected between January 2005 and December 2007.
To find an appropriate method for age determination, sagittal otoliths were observed by surface-reading and frontal section and the results were compared.
The two methods did not differ significantly in estimated age but the surface-reading method is superior in terms of cost and time efficiency.
The sand sole has a moderate life span, with ages up to 10 years recorded.
Individuals grow quickly in their first two years, attaining approximately 48% of their maximum standard length; after the second year, their growth rate dr...
