“…Although there have been many studies conducted along Gökçeada coasts, such as the fish fauna from shallow waters, species composition, fish egg and larvae (Altın and Ayyıldız, 2018;Kocabaş and Acarli 2019;Acarli et al, 2020b;Daban et al, 2020); only one study on the status of P. nobilis population in Gökçeada has been found (Çanak et al, 2006). In this context, the current study aimed to determine the present status of the P. nobilis population in Gökçeada, which is located in the northernmost part of the Aegean Sea.…”

In August 2020, a total area of 38000 m2 around Gökçeada has been scanned to determine the current population status of Pinna nobilis. 9 stations (Yıldızkoy, Manastır, Marmaros, Gizli Liman, Laz Koyu, Kapıkaya, Karaçavuş, Karaçavuş shore and Kefalos) have been detected by means of SCUBA and ABC diving techniques. All specimens were found dead (total mass mortality of 100%). The total length range of P. nobilis was between 30.8 – 38.3 cm.

“…Furthermore, Yalçın Özdilek et al (2018a) reported 37 stranded sea turtles on the Northern Aegean and Sea of Marmara coasts, and 76.5 % of them were reported from the coast of Çanakkale. Kocabaş & Acarlı (2019) indicated seeing an alive adult male loggerhead sea turtle while scuba diving at Gökceada island, North Aegean Sea. In addition to these studies, Yalçın Özdilek et al (2018b) revealed that Gökçeada coasts at the Northern Aegean Sea are foraging habitats of the loggerhead sea turtles from isotopic signatures and they play a carnivorous role in the pelagic food web from the depletion in the mean δ13C value.…”

This study presents the first documented evidence of a loggerhead turtle nest on the northernmost Aegean coast of Turkey which was found on the Gelibolu Peninsula of Çanakkale province, Turkey. The nest contains a total of 74 eggs; 50 of them produced hatchlings and 46 of those hatchlings reached to the sea safely. This record supports the idea that sea turtles search alternative nesting beaches as a result of climate change.

Shipwrecks are one of the most common types of artificial reefs. They are home to several sea creatures, including sea turtles. Here, we aim to understand the relationship between sea turtles and shipwrecks by investigating species occurrence, behaviours and food availability in artificial reefs in Pernambuco, Northeast Brazil. To map sea turtle occurrence in shipwrecks, we considered data from the literature, and we inspected 54,145 photos resulting from 867 recreational dives performed in 19 shipwrecks. We then selected four wrecks for systematic behavioural observations through 97 h and 56 min of passive video recordings. We also investigated potential food resources for turtles in these shipwrecks. We identified three turtle species (i.e., Chelonia mydas, Eretmochelys imbricata and Caretta caretta), but most records were juvenile Chelonia mydas individuals using conserved wrecks. We recorded nine behaviours. ‘Resting’ was the predominant activity for all three species, representing over 60% of the records for all species. Their overall activity pattern varied. The wrecks were predominantly encrusted with ascidia, octocoral, sponge and algae—organisms that are part of sea turtles' diet. We highlight the ecological role of the shipwrecks for sea turtles since they may serve as shelter (especially for the juveniles of Chelonia mydas), potentially protecting them against predators and strong currents. The wrecks may also serve as potential feeding areas for sea turtles. We reinforce the need to establish appropriate regulations for recreational dive tourism in shipwrecks in Brazil to avoid disturbing sea turtles in this ecologically important artificial reef.
