“…H ′ were rather higher than obtained values from some studies conducted on ARs in the Mediterranean Sea. While Fabi et al (2002Fabi et al ( , 2004 and Gül et al (2011) found lower H ′ values, Relini et al (2002), Özgül et al (2016) and Acarlı et al (2020) reported similar H ′ values with the present study.

“…The most abundant families were porgies (Sparidae) and damselfishes (Pomacentridae) for Alaybey and 9 Eylül wreck, respectively. In the Mediterranean Sea, other studies carried out on artificial reefs (concrete blocks, culverts, platforms, wrecks) also reported Sparidae as the most abundant family (Fabi et al ., 2002; Santos et al ., 2005; Gül et al ., 2011; Özgül et al ., 2016; Acarlı et al ., 2020). In accordance with other studies from the Mediterranean Sea (Charbonnel et al ., 2002; Fabi et al ., 2002; Relini et al ., 2002; Guidetti, 2004; Santos et al ., 2005; Özgül et al ., 2016; Acarlı et al ., 2020), Sparidae also clearly dominated the fish richness in this study.…”

“…There are limited fish community studies on such accidental wrecks, in which ROVs (Consoli et al ., 2014; Sinopoli et al ., 2015) and visual census methods were used (Simon et al ., 2013; Sreekanth et al ., 2019). In the Mediterranean Sea, while the fish community studies were mostly conducted with artificial reefs (ARs) such as concrete blocks, pipes and fuel-gas platforms (Charbonnel et al ., 2002; Fabi et al ., 2002; 2004; Lök et al ., 2008; Andaloro et al ., 2011; Gül et al ., 2011; Scarcella et al ., 2011; Consoli et al ., 2013), there was little interest in the artificial wrecks reefs (AWRs) (Simon et al ., 2013; Acarlı et al ., 2020). Although decommissioned vessels are commonly used worldwide especially for recreational diving tourism as an attraction for divers (Leeworthy et al ., 2006), there are few fish community studies on these intentionally placed wrecks (Arena et al ., 2007; Simon et al ., 2013; Walker & Schlacher, 2014; Paxton et al ., 2020; Plumlee et al ., 2020).…”

Deployment of artificial wreck reefs (AWRs) near natural reefs can influence fish assemblages on both reefs. Here, we assessed fish attitudes (abundances, biomass and species richness) according to different level complexity areas of wrecks, feeding guilds of fish and body size of fish of two identical AWRs deployed at the same depth (36.6 m) and different distances from natural reefs. Scuba divers used visual census method to sample fish communities at wrecks for two years. An average of 2346 individuals per dive belonging to 52 species were observed on wrecks combined. Both mean fish abundance and mean biomass did not differ significantly between wrecks. Mean species richness was significantly greater at 9 Eylül than Alaybey. Planktivore was the most abundant feeding guild on wrecks, and its abundance statistically differed between AWRs. The comparisons of fish assemblages at the different level complexity areas of the wrecks show differences, the highest mean abundances were recorded at the areas of low complexity of the wrecks. The results of this study show that although deploying artificial wreck reefs near to natural rocky reefs catalyses fish colonization, it does not present an exact influence on the fish communities of AWRs. We have not known yet how creating an artificial wreck reef affects fish community of natural reefs. With giving extra importance to the choice of deployment area, AWR applications may transform to win-win projects for both the marine environment and recreational users, such as divers and anglers.

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.

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.
