Stomach content analysis of fish not only helps document their food spectrum but also provides an overview of the food network they are involved in. In this study, we aimed to investigate the food composition of L. guentheri from the Iskenderun Bay, northeastern Mediterranean Sea. Specimens were collected between January 2022 and August 2022. A total of 215 L. guentheri specimens stomachs were examined during the study for stomach content analysis. All stomachs were analyzed, 60 (27.9%) were empty and 155 (72.1%) contained food items. Analysis of diet composition showed that the species is carnivorous and prey on teleosts, crustaceans, bivalves and cephalopods. When the food composition of the samples is analyzed numerically, teleost was the most important prey (68%), followed by crustaceans (14%), bivalves (5%), cephalopods (0.5%) and unidentifiable materials (12.5%). Bony fish species such as Plotosus lineatus, Parupeneus forsskali, Saurida lessepsianus, Scorpaena sp. and Siganus sp. were identified in the food composition. Therefore, it is thought that this species has a high feeding tendency towards bony fish species. This study increases the knowledge about the food composition of L. guentheri on the Mediterranean coast of Türkiye. [ABSTRACT FROM AUTHOR]

A group of schools of striped eel catfish Plotosus lineatus (Thunberg, 1787) was photographed during scuba diving at depths of 10 m and 17 m on 11 July 2022 and on 24 September 2022 from Kızkalesi and Boğsak regions in the Mersin Bay of the Mediterranean coast of Turkey. With the present study, P. lineatus is extending its distribution to the western Mediterranean coastal waters after its first occurrence in 2016 in the İskenderun Bay of Turkish Marine waters.

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. [ABSTRACT FROM AUTHOR]
