ANOTHER PECULIAR SITUATION FOR YOY OF BLUEFIN TUNA (THUNNUS THYNNUS) IN THE MEDITERRANEAN SEA IN 2016
The possible effects of the hottest temperatures recorded in 2016 (the hottest so far) on the bluefin
tuna reproductive biology have been discussed by the SCRS in the past, but the situation in 2016
was very different. After collecting some detailed samples and data about the presence of YOY in
various parts of the Mediterranean Sea, an unusual situation can be observed, showing different
size-at-time by area in late summer-fall 2016, possibly mirroring early, late, fractioned and
continued spawnings and different growth rates. These fish might result in future problems for
age readings and ALK at least for the juveniles of bluefin tunas born in 2016. This paper provides
the growth curves for the many cohorts of bluefin tuna YOY which have been detected and that
were born in 2016
