Abstract. One specimen of Seriola fasciata was caught by a commercial trawler at depths of 60-70m on 10 November 2018 from the Çevlik coast of Turkey Iskenderun Bay. The present paper reports the second record of Seriola fasciata in Turkish Marine waters.
Key words: Seriola fasciata, lesser amberjack, alien species, Occurrence, Iskenderun Bay.
Fishes of the family Carangidae, with 146 recognized species (Froese & Pauly 2018), are mainly marine fishes of tropical and subtropical waters of Western Atlantic and Eastern At- lantic (Froese & Pauly 2018). The lesser amberjack fish Seriola fasciata (Bloch, 1793) is distributed in the north-eastern At- lantic (northwest Spain, Azores, Madeira Island); west At- lantic, (north America), and the Mediterranean Sea where it . S. fasciata was recorded for the first time from Balearic Is- lands (Spain) in the Mediterranean Sea in 1989 (Massutí & Stefanescu 1993, Tiralongo et al. 2018). The other Mediterra- nean records were then reported from Mediterranean: Spain (Massutí & Stefanescu 1993), France (Riera et al. 1995), Italy,
Tunisia (Quignard & Tomasini 2000.), Greece (Corsini et al. Figure 1. Seriola fasciata caught of Çevlik, on 10 November2018. 2006), Turkey (Kapiris et al. 2014), Syria (Jawad et al. 2015), Israel (Sonin et al. 2009) and Egyp (Stamouli et al. 2017). S. fasciata is a benthopelagic species adults are found mainly near the substrate at depths between 55 and 130 m while juveniles are epipelagic. This species feeds mainly on small fishes, crustaceans and cephalopods (Andaloro et al. 2015, Froese & Pauly 2018) and can reach a fork length of 67.5 cm and a weight of 4.6 kg (Sonin et al. 2009). Seriola fasciata in Turkey was firstly recorded from Anta- lya Bay (Kapiris et al. 2014). We hereby report the second re- cord of S. fasciata in the Çevlik coast, the Iskenderun Bay in Turkish Marine Waters.
On 10 November 2018, one specimen of S. fasciata (Fig. 1) was cap- tured by a commercial trawler from the Çevlik coast (36°06'36"N - Figure 2.
