This study investigated artisanal fishing activity near sea cages in Güllük Bay in the southeastern Aegean Sea based on dockside sampling with local fishermen. The daily fishing activity of bogue Boops boops gillnetters was randomly observed in the ports of Göltürkbükü, Gündoğan, Yalıkavak and Torba over two fishing seasons, from November to April 2018 and 2019. A total of 18,163 kg of fish were caught in 147 daily operations. The composition of catches from the bogue gillnet fishery comprised 48 species from 30 families, including both fish and invertebrates. B. boops was the most abundant species with 91.9% of the catch, followed by Diplodus annularis, Scomber colias, Trachurus trachurus, Pagellus acarne and Scomber scombrus. The ratio of total bycatch biomass to commercial target species was 1:0.09. The fork length (FL) and weight of the 536 sampled B. boops ranged between 25.5 ± 0.12 cm and 293.6 ± 3.87 g, respectively. The highest catch per unit effort (CPUE) of B. boops occurred in April and averaged 58.83 ± 11.47 kg/1000 m, likely due to an increased catch during its spawning migration to open sea areas in spring.

The first record of caudal fin-deformed wild fish, Conger conger (Linnaeus, 1758) from the northern Aegean Sea, Turkey was reported. The tail-deformed specimen with 370 mm Total length, 24 mm preorbital length, 14 mm eye diameter and 89 mm head length. The caudal region of the deformed specimen was completely deformed and fused, and the tail length of the abnormal fish was 33.3% when compared to the tail of the normal specimen. Possible reasons that are the cause of found abnormality such as viral, bacterial or environmental pollution are discussed. The abnormality could be considered an important indicator of environmentally induced stress since in the described area there is a significant pollution of heavy metals. The cause could be a spontaneous genetic mutation since the finding was a single specimen and not a frequent state in other fish within the studied area. Nevertheless, the present finding highlights the need for closer monitoring of the marine environment and for the identification of the specific factor that caused this abnormality.

On 8 February, 3 May, and 9 May 2025, three specimens of Monachus monachus were photographed by a staff diver at two fish farms rearing sea bass and sea bream in Gerence Bay, Izmir, in the Aegean Sea. A comprehensive set of behavioural data on Mediterranean monk seals was obtained from the diver via an interview. The findings confirm the near-permanent presence of monk seals in the study area. The paper also suggests that excessive dependence on fish farms could alter the monk seals' feeding behaviour and potentially even lead to their domestication.

This paper presents an update of the Mediterranean distribution of Pterois miles, based on a comprehensive list of geo-referenced occurrences up to luly 2024, including a maximum size report. On 1 1 July 2024, a huge specimen of P. miles was captured by commercial trammel net at a depth of 40 m off Kadtrga cove, Marmaris, Mugla. The specimen has a total length of 437 mm and a wet weight of 1268 g. Following the initial Mediterranean record of P. miles in Israel in 1991, the species has exhibited a relatively rapid dispersal rate, subsequently expanding to the northern Aegean Sea (Edremit Bay) and southern Aegean Sea (southern Crete) as well as the Libyan Sea between 2016 and 2018. Since then, the species expanded its distribution range to the northernmost limit of the Adriatic Sea, reaching as far as Southern Sicily and the Gulf of Tunis.

Il 17 febbraio 2024, dodici esemplari di Champsodon nudivittis sono stati catturati da un peschereccio commerciale a strascico per la pesca dei gamberi nelle acque costiere di Karabiga, nella provincia di Çanakkale, a una profondità compresa tra i 45 e i 65 m. 11 presente lavoro presenta le segnalazioni aggiornate di C. nudivittis nei Mediterraneo, compresa la recente presenza nei Mar di Marmara, in Turchia.

Two specimens of the Lessepsian migrant S. suezensis were captured by trammel net on 2 August 2022 off Akyaka, Gökova Bay, Turkey at a depth of 2 m over a sandy bottom. This finding documents the third occurrence of S. suezensis in the south-eastern Turkish Aegean Sea. It is also the second northernmost record of the taxon in the Mediterranean Sea.

A specimen of Lutjanus argentimaculatus (Forsskål, 1775) was caught on 4 October 2018 by a commercial gillnet fishery from shallow waters of the Gulf of Izmir, northern Aegean Sea, at a depth of 8 m. The presently reported study constitutes the first record of the mangrove red snapper for the Aegean Sea but also the third record for the Mediterranean Sea.

L'articolo riporta un ritrovamento di Seriola fasciata che suggerisce l'estensione della distribuzione della specie nel Mediterraneo orientale. L'8 settembre 2021, un singolo esemplare di S. fasciata e stato catturato con un tramaglio ad una profondita di 30-40 m, al largo dell'isola Yılancık, Marmaris, nell'Egeo sud-orientale. Questo pesce termofilo e ancora molto raro (circa 24 esemplari riportati fino ad ora) nel Mediterraneo orientale. Questo ritrovamento e il secondo di S. fasciata per il Mar Egeo turco e il quarto per tutti i mari turchi.

L'articolo mira a completare e aggiornare i dati relativi alla distribuzione del pesce arabo, Pomadasys incisus, riportando l'estensione della distribuzione di questa specie nel Mediterraneo orientale. Il 1° novembre 2020, un singolo esemplare di P. incisus è stato catturato da un pescatore su un fondo sabbioso/ roccioso ad una profondità di 3 m, ad Akyaka, nella baia di Gökova, nel Mar Egeo sud-orientale. Questo pesce termofilo è ancora molto raro nel Mediterraneo orientale (circa 142 esemplari segnalati finora). Tuttavia, è ovvio che le popolazioni di P. incisus si stiano gradualmente espandendo verso le latitudini settentrionali del bacino orientale e occidentale del Mediterraneo.

This paper presents the first recorded sighting of a Stephanolepis diaspros school at a sea-cage fish farm in the Bay of Izmir, north-eastern Aegean Sea. On 17 December 2024, a group of 20 individuals of S. diaspros was observed around a sea cage used for rearing meagre (Argyrosomus regius) off Urla, at a depth of 30 m. This study not only documents the first observation of S. diaspros in a fish farm in the northern Aegean Sea but also provides the first evidence of this fish species intruding into sea cages.
