    A review of the marine crab fisheries in the Turkish seas
    (Sciendo, 2018) Harlıoğlu, Muzaffer Mustafa; Farhadi, Ardavan; Ateş, Abdullah Suat
    The paper presents a review of the distribution of marine crabs (Brachyura) along the Turkish coast and the amount of economically important marine crabs harvested between 1967 and 2016. Previous records reported that Turkey had 102 brachyuran crab species, only five of them being economically important, but this review identifies two more species, Inachus phalangium and Ashtoret lunaris. The Aegean Sea has more crab species than the Mediterranean, the Black Sea and the Sea of Marmara. The most harvested species are Callinectes sapidus, Maja squinado, Eriphia verrucosa, Carcinus aestuarii and Portunus segnis, respectively. This review shows that there have been fluctuations in the harvest of marine crabs between years, the lowest being 5 tonnes in 2015 and the highest, 2116 tonnes in 1984. The information provided in this review provides a basis for potential profitable development of conservation and management strategies of marine crabs in Turkey. © The Author(s) 2018.

    Exotic Polychaetes of a Sewage Pollution Influenced Lagoon (cardak Lagoon, Turkish Straits)
    (MDPI, 2023) Dağlı, Ertan; Ateş, Abdullah Suat; Acar, Seçil; Büyükateş, Yeşim; Dogan, Alper; Bakır, Ahmet Kerem
    This paper includes three exotic polychaeta species, Hydroides dianthus (Verrill, 1873), Polydora cornuta Bosc, 1802, and Pseudopolydora paucibranchiata (Okuda, 1937), found during benthic samplings in Çardak Lagoon (Turkish Straits). The sampling was collected from the sandy and silty bottoms known to be polluted by sewage discharges. A total of 45 specimens of exotic polychaetes (H. dianthus: 1; P. cornuta: 4; P. paucibranchiata: 40) were found. The correlation values between the annual average values of the nutrients and the polychaeta abundance showed that the highest positive relationships with the abundance were between sand content, total phosphate, and pH. P. cornuta was the most observed species with a frequency index value of 75%, while H. dianthus was represented with a single species in the study area. Albeit the previous studies, P. paucibranchiata was observed most abundantly in the sampling station having low organic matter amounts. The study showed that opportunistic polychaetes observed in Çardak Lagoon mostly preferred organically poor sediments.

    Physical carrying capacity of a potential aquaculture site in the Mediterranean: the case of Sigacik Bay, Turkey
    (Springer, 2021) Yigit, Murat; Ergün, Sebahattin; Büyükateş, Yeşim; Ateş, Abdullah Suat; Özdilek, Hasan Göksel
    The aim of the present study was to evaluate physical carrying capacity of a potential cage aquaculture site near a Cittaslow area in the northern part of the Mediterranean (Sigacik Bay, Turkey). Developing tools for timely management of marine aquaculture facilities are important to minimize harmful influences of fish farming. The physical carrying capacity was estimated by mathematical formulations previously developed for the same area, using data of topographical characteristics of the site, production capacities, and leased area information of fish farms in total. Based on the findings of the present study, estimated physical carrying capacity of the potential aquaculture site with a total area of 38.9 ha near the Cittaslow residential area of “Sigacik Bay” was found as 27,694 tons of fish production which is more than 2-fold of the present production level that is around 11,800 tons in the area. Therefore, it might be concluded from a physical point of view that the production level of the present cage farms in Sigacik Bay is below risk levels.

    Temporal and spatial effects of environmental variables on crustacean communities in Çardak Lagoon (Turkish Straits System) under the influence of domestic pollution
    (Springer Science and Business Media Deutschland GmbH, 2023) Ateş, Abdullah Suat; Mülayim, Ayşegül; Bakır, Ahmet Kerem; Acar, Seçil; Büyükateş, Yeşim; Dağlı, Ertan; Doğan, Alper; Uzundumlu, Sinan; Kedioğlu, Çetin
    This study presents the temporal and spatial effects of domestic pollution on crustacean assemblages in a protected area, Çardak Lagoon (Turkish Straits System). The samplings were performed from sandy and mud (silt + clay) bottoms between 1 and 1.8 m depths in October 2018, February, April, and June 2019. A total of 6920 specimens and 26 species (1 Isopoda, 1 Tanaidacea, 2 Mysidacea, 3 Cumacea, 5 Decapoda, 14 Amphipoda) belonging to crustaceans was found. Highest crustacea abundances were in autumn and winter. Considering the environmental variables, NO2 + NO3 (mg L− 1) and COD (mg L− 1) levels in the water had the highest correlations with abundance for the sampling periods. According to sampling points, the highest correlation value was found between anionic detergent content in the water and the abundance. Crustacean community structure was modified by environmental variables of anthropogenic origin at a higher level. Oxygen, oxygen reduction potential, NO2 + NO3, total nitrogen, chemical oxygen demand and anionic surfactant levels in water and sediment sand content % were major environmental variables affecting the crustacean abundance in the study area temporally.
