Since 2015 Turkish fishing fleet has been catching both pelagic and demersal fish in the coastal waters of the Islamic Republic of Mauritania. Total number of boats has been 51 in the Mauritanian waters, of which 33 are purse seiners and 18 are deep sea trawlers. Among these boats nine of them have returned to Turkey for various reasons but 42 fishing boats are operating at present (June 2018) in the Mauritanian waters. These fishing activities represent about a $200 million investment. Protection of the local people’s food demand has a vital importance and sustainability of the stocks should be the main target for the sustainable fisheries and food safety. Turkish investors has contributed to the social development, welfare and job creation in Mauritania. In addition, they also contribute to the education of the local citizens about fishing industry.

One specimen of the diamondback puffer, Lagocephalus guentheri (Miranda Riberio, 1915), was recorded along the Turkish coast, off Gökova Bay, through the angling method on 12 June 2017. The morphological features of this species were examined indirectly by image analyses software. This finding also supports the documented occurrence of the diamondback puffer fish along Turkish coasts.

This paper reports the first record of Kogia sima (Owen, 1866) in Morocco (Strait of Gibraltar) and the forth for the Mediterranean Sea. On 30 April 2015, in Mnar-Tanger (Morocco) a stranding of dwarf sperm whale, K. sima was found. This species is rarely observed at sea and little is known from the Mediterranean Sea.

The present paper reports the first record of Adriatic sole Pegusa impar (Bennett, 1831) from the Syrian coast. This record confirms the occurrence of the species in the Levant Basin but does not suggest that a viable population is successfully established in this region. Its rarity in the area is probably due to misidentifications with other congeneric species.

First record of the spotted sea hare Aplysia dactylomela Rang, 1828 in the south Mediterranean coast (Kuriat Islands, Tunisia)

The spotted sea hare Aplysia dactylomela Rang 1828 was recorded for the first time in the Mediterranean Sea in 2002. This non-native species then spread rapidly eastwards from the waters surrounding Lampedusa Island to reach the Levantine coast, following the main Mediterranean current movement. Despite the colonization of the eastern Mediterranean basin in numerous localities, no sightings were reported from the western Mediterranean basin. In July 2017, two specimens of this species were sighted about 1 m depth surrounding the future MPA of Kuriat Islands. The observation was made during the implementation of the national Integrated Monitoring and Assessment Programme (IMAP) in Tunisia related to the biodiversity component.

The presence of Pinna nobilis L. in the Gulf of Neum as an argument for reevaluation of its conservation status in Bosnia and Herzegovina

The presence of the Mediterranean endemic bivalvia fan shell Pinna nobilis L. was recorded during a survey that took place in Neum Bay 37 years ago. Since then its presence has only been confirmed once although it is protected by several international protocols. The aim of this research was to collect the data that can be used for a better undersanding and preservation of P. nobilis. An area of 400 m2 was searched for individual shells by SCUBA diving. Five individuals found at a depth ranged between 3 and 9 m. Bosnia and Herzegovina is the only country on the Adriatic Sea that has not protected the fan shell by law. Further surveys must be undertaken as soon as possible, with the proper management of this habitat which hosts P. nobilis.

A specimen of Lessepsian migrant, Stephanolepis diaspros, 257 mm in total length, was caught on 10 January 2018 by a scoop net in Göltürkbükü fishing port, Güllük Bay, on the sandy bottom at a depth of 1 m. This record was the maximum size for both the Turkish seas and the Mediterranean.

Caulerpa taxifolia (Vahl) C. Agardh var. distichophylla (Sonder) Verlaque, Huisman and Procacini is an invasive green alga recently reported in the Mediterranean Sea. The first record was in Turkey in 2007 and later it has been reported in Sicily (2009), Cyprus (2013), Malta (2015), Rhodes (2016) and Libya (2017). In the current study we present additional records of this species expanding its range into the Eastern and Western Mediterranean Sea (Eastern and Western Sicilian shoreline, Calabrian Tyrrhenian coast, Sardinia and Tunisia) as well as in the eastern Mediterranean basin. Our specimens were collected on various substrates and identified morphologically.

The Mediterranean monk seal, Monachus monachus (Hermann, 1779), is an endangered species according to International Union for the Conservation of Nature (IUCN) Red List. Therefore it is of high importance to monitor mortality/survival of all individuals to ensure the sustainability of the population. Eighteen monk seals were found dead on the Turkish coasts of the Aegean and Mediterranean Seas between February 2012 and April 2018. This paper reviews those strandings during the seven-year period with the preliminary necropsy findings of three new records; a female pup found in Antalya on 25 November 2017, an adult female found in Muğla on 7 March 2018, and an adult female stranded on 16 April 2018 on the coast of İzmir. There are various illness causes, virological, parasitological, or microbiological, which effect monk seals, thus systematic necropsies must be performed as soon as possible on carcasses.

Length–weight relationships of 13 fish species from the western Black Sea (Zonguldak-Amasra), Turkey

In this study, length-weight relationship (LWR) parameters are reported for 13 fish species collected from the western Black Sea and a total of 3132 fish individuals were sampled. The b values varied from 2.84 for Scorpaena maderensis to 3.49 for Trachurus mediterraneus, with a mean of 3.13 (±0.074). The LWRS and regressions for all species were highly significant (P<0.05), whereas they were isometric for six species (Merlangius merlangus, Sprattus sprattus, Trachinus draco, Pomatomus saltatrix, Trachurus trachurus and Chelidonichthys lucernus). Two species (Scorpaena porcus, Scorpaena maderensis) showed negative allometry and five species (Mullus barbatus, Merluccius merluccius, Engraulis encrasicolus, Trachurus mediterraneus, Uranoscopus scaber) indicated positive allometry. In this study, LWR for S. maderensis in the Black Sea was investigated for the first time.
