Abstract: The aim of the study was to determine the returning of current and
former species in their native lands, the Galata Bridge and the Ataturk
(Unkapani) Bridge, at Golden Horn during the periods from October 2005 to May
2006 – stations on which established fisheries were determined and inland
distances where these fisheries were viewed and observed. At the end of the
observations, thirty-four species were determined at Golden Horn. Fifteen
species, Hippocampus hippocampus, Solea vulgaris, Atherina boyeri, Thrachurus
trachurus, Maena smaris, Psetta maxima, Diplodus vulgaris, Gobius
batrachocephalus, Boops boops, Boops salpa, Merlangius euxinus, Lithognathus
mormyrus, Alosa fallax nilotica, Trachinus draco, and Belone belone gracilis
were observed for the first time differently from the previous studies (Yuksek
et al., 2006). Economically important species like Mullus surmuletus, Mugil
cephalus, Sarda sarda, Pomatomus saltator, Psetta maxima, Engraulis
encrasicolus, Trigla lucerna, Belone belone, Trachurus trachurus, Solea
vulgaris, Diplodus vulgaris, Lithognathus mormyrus, and Merlangius euxinus were
frequently determined. Furthermore the length sizes of the same species that
were observed at the selected stations were compared statistically (P>0.05).
Consequently, positive influence of rehabilitation studies started in 1995 on
the increasing of the species and the amounts was researched.
