The
mean
curve
carapace
length
of
the
turtles
was
68.8
cm
 (SD
=
±
10.3
cm;
range
=
32.0‐84.5
cm;
n
=
40).
Haplotype
CC‐ A2.1
(93%)
was
the
dominant
haplotype
in
the
region.
 Furthermore,
2
novel
haplotypes
were
described
(CC‐A6.1
and
 CC‐A10.4)
for
the
first
Lme
with
a
record
of
another
known
 haplotype,
CC‐A.2.8.
This
haplotype
(CC‐A.2.8)
was
recorded
 from
a
juvenile
stranded
in
Puglia
(South‐AdriaLc,
Italy)
in
May
 2008
(Garafalo,
2010).
Haplotype
and
nucleoLde
diversity
 were
0,14615
and
0,00017
respecLvely.
The
adult
female
with
 AL0127
tag
number
was
recorded
nesLng
in
Sekania,
 Zakynthos
July
2011
(Margaritoulis
pers
comm.)

Discussion In
terms
of
frequency
of
haplotypes
and
their
occurrence
in
 the
Mediterranean,
the
possible
source
of
foraging
area
in
 Patoku,
we
were
able
to
compare
our
results
with
shorter
 sequences
from
the
Mediterranean
(Carreras
et
al.,
2007;
 Yılmaz
et
al.,
2011).
The
highest
frequency
of
the
haplotype
 CC‐A2.1
in
the
region
is
not
surprising
since
it
is
the
variety
of
 the
short
haplotype
CC‐A2,
the
most
common
haplotype
in
 the
Mediterranean
(Table
2).
The
short
form
of
haplotypes
CC‐ A6.1
and
CC‐A10.4,
CC‐A6
and
CC‐A10
were
recorded
only
 from
Greek
islands
and
Greece
(Table
2).
Bowen
et
al.
(2004)
 stated
that
nesLng
populaLons
contribute
more
to
 neighbouring
mixed
stocks
than
the
distant
mixed
stocks.
So,
 it
is
probable
that
the
source
populaLon
of
the
Drini
Bay
is
 mainly
originated
from
Greece.
The
nesLng
record
of
AL0127
 tag
number
female
in
Sekania,
Zakynthos
July
2011
further
 support
this
possibility.
In
another
study,
the
foraging
grounds
 off
the
coasts
of
western
Mediterranean
have
been
shown
to
 be
inhabited
mainly
by
turtles
from
the
eastern
 Mediterranean
(Carreras
et
al.
2006).
This
study
revealed
 different
structure
between
northern
African
and
western
 Mediterranean
stocks
and
this
structure
was
explained
by
sea
 currents
and
water
masses.

 In
conclusion,
the
current
findings
support
that
the
source
 populaLon
of
Drini
Bay
foraging
loggerhead
turtles
are
 probably
from
Greece
but
we
need
to
increase
sample
size
in
 order
to
carry
out
mixed
stock
analysis
and
evaluate
the
 contribuLon
of
nesLng
colonies
to
this
foraging
ground.
