A new record of lessepsian migrant etrumeus teres (DeKay, 1842) (Osteichthyes: Clupeidae) from the northern aegean sea

Abstract

The east coast of the Aegean Sea is characterized by a large number of bays and islands and a dynamic seabed relief. Whereas the climate is both warm and nutrient-rich in the South Aegean, the oceanographic conditions are quite different in the northern part (Stergiou et al., 1997). The North Aegean is colder (11C in spring) and more saline (annual mean 37&) and the southern part is hotter (14.4C) and less saline (38.91 &) (Benli et al., 2000; Türker Cakır, 2004). The north-east coast has strong upwelling systems, affecting the biodiversity (Türker Cakır, 2004)
