The samples were collected seasonally during 2012–2015 in the coastal area of İskenderun Bay using a WP-2 zooplankton net (200 µm). Six cladoceran species were found in total, and<em> Penilia avirostris, Pseudevadne tergestina </em>and<em> Evadne spinifera </em>constituted the bulk of the population, while the contribution of <em>P. schmackeri </em>was very low. Although only a single individual was observed in July 2012, the abundance and frequency of<em> P. schmackeri </em>increased in the following years, attaining the abundance of 25.10 ind.m<sup>-3</sup> in 2015. Thus,<em> P. schmackeri </em>could be considered as established in İskenderun Bay; however, it seems that it did not affect the distribution of other cladoceran species in the area up to now<em>. P. schmackeri </em>could have entered in İskenderun Bay either as Lessepsian migrant or by ballast waters of commercial ships.</p><p><em><br /></em></p> ER -
