Age estimation of juvenile bluefin tuna, Thunnus thynnus, from the Mediterranean sea

Megalofonou P., Platis K., De Metrio G., Santamaria N.

The sagittae of juvenile bluefin tuna captured in the Mediterranean Sea were prepared using sectioning and immersion in Methylbenzoat reinst. Counts of presumed daily growth increments were performed. Estimated ages ranged from 15 to 162 days of fish ranging in size from 8.5 to 55.5 cm fork length. A growth rate of 4.5 cm per day for the range of size of the fish was estimated. Most of the back calculated spawning days were found in June, July and August.
