Population structure of loggerhead sea turtles, Caretta caretta, in the Adriatic Sea

The Adriatic Sea is an important feeding habitat for loggerhead sea turtles in the Mediterranean. Its shallow northern and central waters host one of two the most extensive neritic habitats in the basin, whilst the southern Adriatic is considered oceanic habitat. Analysis of tag returns showed that at the adult female level, the Adriatic is frequented by loggerheads belonging to regional nesting stocks, predominantly to the Greek reproductive population. In the case of juveniles, it has been hypothesized that Adriatic developmental habitats may be shared by turtles of regional and Atlantic origin. To asses genetic structure and natal origin of loggerheads in the Adriatic Sea, we sampled 116 turtles with CCL ranging from 8.5 - 84.5 cm (mean CCL = 42.9, SD = 14.7) found in Croatian and Slovenian waters and analyzed mitochondrial DNA control region sequences. Most of the turtles in this study were juveniles (111 ex) with CCL < 70.0 cm. We detected eight distinct haplotypes. Six were previously reported from the Mediterranean (Cc-A2, Cc-A3, Cc-A6, Cc-A26, Cc-A29, Cc-A32), whilst the remaining two are new and can not be assigned to a rookery of origin. Based on Bayesian mixed stock analysis results, we discuss natal origin of loggerheads in the feeding habitats of the Adriatic Sea and their implication to conservation, fishery management in particular.
