Abstract


The big-scale sand smelt, Atherina boyeri Risso, 1810 was recorded for the first time in Büyükçekmece Reservoir in 1982. However, the following studies on ichthyofauna indicated that A. boyeri does not exist in this reservoir. In the present study, reoccurrence of A. boyeri population was determined in the northern coast of Büyükçekmece Reservoir at December 10, 2015. Because of a total of 22 individuals belonging to different size groups (3.1-6.1 cm in standard length) were caught, it can be considered that A. boyeri has successfully colonized again in this reservoir.
