“…It is the only species of the Lobotidae Gill, 1861 that occurs in the Mediterranean Sea, where it is mostly reported as a localised catch in several parts of the basin. So far, it has been reported from Algeria, Croatia, Egypt, Greece, Israel, Italy, Lebanon, Malta, Spain, Turkey and Tunisia (Akyol & Kara, 2012;Akel & Philips, 2014;Dulčić et al, 2014;Kavadas & Bekas in Katsanevakis et al, 2014;Tiralongo in Dailanis et al, 2016); therefore, records from Cyprus are lacking. This is the first report on this species from Cypriot territorial waters, based on old and recent evidence.…”

In the present Collective Article information on 26 taxa belonging to 8 Phyla and extended from the western Mediterranean to the Levantine Sea are presented. The new records were found in 9 countries as follows: Spain: first record for the Mediterranean of the crab Cancer bellianus; Algeria: further records of the alien fish Lagocephalus sceleratus to the west Algerian waters; Italy: first report on the presence and establishment of the ctenophore Mnemiopsis leidyi in Lessina and Varano Lagoons (W. Adriatic) and of Penaeus aztecus in Corigliano Gulf (Italian Ionian). Moreover, the extension of the distribution range of the polychaete Branchiomma bairdi to W. Sicily as well as that of the crab Ocypode cursor and the bryozoan Catenicella paradoxa to E. Sicily are cited. Slovenia: the record of the rare saccoglossan gastropod Placida cremoniana from Piran (Gulf of Trieste) is the first for the Adriatic; Greece: the native sea slug Eubranchus farrani is the first from the Eastern Mediterranean; many sightings of the bamboo corals Isididae distributed along all the E. Ionian Sea and the establishment of P. aztecus in all Greek waters are also reported for first time; the westernmost extension of the alien urchin Diadema setosum in Cretan waters is cited and new sights of the alien species Goniobranchus annulatus and Pterois miles are shown. Turkey: the alien fish Champsodon capensis is reported for first time from the Aegean Sea and the native acari Agauopsis microrhyncha from the Levantine Sea; a new observation of the alien crab Atergatis roseus in Güllük Bay-Aegean is also mentioned; Cyprus: first records of the alien urchin D. setosum and Lobotes surinamensis in Cypriot waters; Lebanon: several sightings of Monachus monachus from the Lebanese waters indicate a potential better status of the species in the area, Egypt: first records of the alien crab Dorippe quadridens and the alien gastropods Nerita sanguinolenta and Conomurex persicus from the Mediterranean Egyptian waters; extension of the distribution range of Diodora funiculata and Diodora rueppellii and a second record of the alien Nerita sanguinolenta in the same area.

“…Previously reported CPUE for boat seine fishery values were 13 kg/haul (Faltas, 1997) and 8 kg/haul in the Abu Qir Bay (Egypt) (Faltas and Akel, 2003), 24.9 kg/haul in the eastern Adriatic Sea (Croatia) (Cetinić et al, 2011), and 37.9 kg/haul in Alexandria (Egypt) (Akel and Philips, 2014); in this study of the İstanbul Strait, the CPUE was 42.5 kg/haul. Differences in environmental factors, such as productivity, seabed characteristics, depth, and fishing pressure, affect catch composition, landings, and discards (Carbonell et al, 2003, Sanchez et al, 2007.…”

“…In this study, a total of 29 species were obtained by the boat seine fishery in the İstanbul Strait, Turkey, compared to 70 species in the Aegean Sea, Turkey (Akyol, 2003); 60 species along the central coast of Portugal (Cabral et al, 2003); 45 species in the Aegean Sea, Turkey (Tosunoğlu, 2003); 48 species in the Sea of Marmara, Turkey (Zengin et al, 2004); 46 species in the eastern Ionian Sea and 62 species in the Aegean Sea, Greece (Katsanevakis et al, 2010); 91 species in the eastern Adriatic Sea, Croatia (Cetinić et al, 2011); and 46 species in Alexandria, Egypt (Akel and Philips, 2014). The number of affected species in this study was low due to the low species diversity of the İstanbul Strait, and so the composition of the total catch was less diverse than that of other studies.…”

This study attempted to determine certain characteristics of the species caught in the boat seine fishery in the İstanbul Strait during the 2009-2010 fishing season, including catch composition, commercial and nontarget catch ratios, catch per unit effort (CPUE), and the length distributions of commercial species. A survey of 20 boat seine operations detected species belonging to the following 3 different taxonomic groups: 26 Osteichthyes, 2 Crustacea, and 1 Mollusca. Of all of the nontarget species, 13 were commercial, 14 were noncommercial, and only 1 was under threat. Of the total catch, the proportion of the commercial species in the nontarget catch was 31.3%, and that of the discarded catch, which the fishermen did not take into account, was 2.8%. According to the Spearman rank correlation test, there was a significant correlation between the total catch and the discarded catch (r = 0.759); the size of discarded catch increased as the catch increased (P = 0.000). It was clear from the data that overfishing was seen in the commercial species.

“…Species diversity in the catch would have theoretically been much higher if it operated in more variety and wider area of fishing grounds. Beach seines, as usually common, operate at places where nursery grounds of most fish occur (Akel and Philips, 2014). However, this is the characteristic nature of small scale and mostly subsistence fisheries, as particularly common.…”

“…On the contrary, minitrawls and Danish Seines are much bigger size, and always moving from one fishing ground to the other (Garces et al, 2006). Beach seines in many developed countries are still considered as legal fishing gear (Gray and Kennelly, 2003;Cabral et al, 2003;Akel and Philips, 2014;Lombardi et al, 2014), and in developing countries as well (Monteclaro and Abunal, 2013;Nunoo and Azumah, 2015). So, with very low catch contribution, and very limited and localized effect on bottom habitats, beach seine should not be treated as equal as their relatives, such as trawls and other seine nets.…”
