Saros Körfezi (Kuzey Ege Denizi, Türkiye)’nden Avlanan Benekli Pisi Balığının (Lepidorhombus boscii Risso, 1810) Bazı Üreme Özellikleri

Tarım Bilimleri Dergisi (2015)

Özgür Cengız Uğur Özekinci Ali İşmen Alkan Öztekin

Bu çalışma Eylül 2006 - Eylül 2008 tarihleri arasında Saros Körfezi (Kuzey Ege Denizi, Türkiye)'nde gerçekleştirilmiştir. Balık örnekleri 0 - 500 m arası derinliklerde ayda bir defa torba ağ gözü açıklığı 44 mm olan ticari dip trolü ağı kullanılarak toplanmıştır. Benekli pisi balığının (Lepidorhombus boscii Risso, 1810) üreme döneminin Şubat-Mayıs ayları arasında olduğu belirlenmiştir. İlk üreme boyu dişi bireyler için 14.9 cm, erkek bireyler için ise 15.3 cm olarak saptanmıştır. Türün mutlak yumurta verimliliği - toplam boy, mutlak yumurta verimliliği - toplam ağırlık ve mutlak yumurta verimliliği - yaş arasındaki ilişkiler sırasıyla F= 1.487×TL3.22, F= 264.39×TW + 14.103 ve F= 12.207×A -11.279 olarak tespit edilmiştir. Bu çalışma benekli pisi balığının Türkiye sularında bazı üreme özelliklerine ilişkin ilk verileri içermektedir.

Growth performance of bath sponge (Spongia officinalis Linnaeus, 1759) farmed on suspended ropes in the Dardanelles (Turkey)

Aquaculture Research (2011)

İhsan Çelik Şükran Ci̇ri̇k Uğur Altınağaç Adnan Ayaz Pınar Çelik

Commercial bath sponge population in the Mediterranean has been recently reduced due to diseases and the depletion of natural banks. The commercial supply is far below the demand on the last 10–15 years. In this study, we aimed to investigate the farming performance of Spongia officinalis in the Dardanelles. Sponges collected from the Dardanelles cut into pieces of different weight. They were divided into two groups depending on the wet weight ranging from 50 to 150 g (mean weight 102.6 ± 4.81 g) and from 160 to 360 g (mean weight 235.8 ± 8.56 g). Three rope systems located parallel to each other with 6–7 m inter-distance were constructed for the cultivation of sponges. At the end of the study, while small-sized sponges could reach mean wet weight of 120.7 ± 14.8 g, large-sized sponges reached mean wet weight of 247.6 ± 22.4 g. Growth rates were estimated 5–17% at 21st month. The survival rates were found 82% and 88%.

New and confirmed records and rare occurrences of some deep sea fishes in the Turkish waters of the northern Aegean Sea (Mediterranean Sea)

Cem Dalyan Onur Gönülal Nur Bikem Kesici Lütfiye Eryılmaz Sezginer Tunçer

There are very few locations in the Turkish waters which are suitable for deep sea investigations and the northern Aegean Sea is one of them. This study provides information on the distribution of some deep sea fish species, with their rare occurrences in the northern Aegean Sea. The study was conducted in the Turkish territorial and adjacent waters of the northern Aegean Sea between the years of 2011 and 2019. The aim of this study was to investigate the fishes of depth zones below 200 meters. The results of the study revealed range expansions of some of the deep sea teleost as well as the first and the second record of some species in the Turkish waters of the northern Aegean Sea. This study also includes the confirmed records of Lestidiops sphyrenoides (Risso, 1820) and Epigonus denticulatus Dieuzeide, 1950 from the Aegean Sea, first records of Lophotus lacepede Giorna, 1809 and Stomias boa (Risso, 1810) in the Turkish waters of the Northern Aegean Sea as well as the second records of Nemichthys scolopaceus Richardson, 1848 , Ceratoscopelus maderensis (Lowe, 1839), Lampanyctus crocodilus (Risso, 1810) , Lepidion lepidion (Risso, 1810) and Epigonus constanciae (Giglioli, 1880).

Antalya Körfezi’nde Beyaz Sokar (Siganus rivulatus Forsskål, 1775) Avcılığında Kullanılan İğnelerin Seçiciliğinin Belirlenmesi

Çanakkale Onsekiz Mart University Journal of Marine Sciences and Fisheries (2018)

Fatih Yavuz Alkan Öztekin

Bu calismada, Antalya Korfezi'nde Kumluca, Finike, Demre ve Kemer ilceleri sinirlari icerisinde subtropikal ve lesepsiyen bir tur olan Beyaz sokar’in (Siganus rivulatus Forsskal, 1775) olta ile avciliginda kullanilan 6, 8, 10 ve 12 numara kisa sapli capraz celik ignelerin secicilikleri SELECT metodu kullanilarak hesaplanmistir. Calismada yapilan 16 operasyonda toplam yakalanan beyaz sokar baligi sayisi 406 adettir. Log normal modele gore 6, 8, 10 ve 12 numara ignelerin optimum yakalama boylari sirasiyla; 20,79 cm, 17,67 cm, 14,91 cm, 12,60 cm ve yayilim degerleri ise sirasiyla 13,65 cm, 11,60 cm, 9,79 cm ve 8,28 cm olarak tespit edilmistir. Beyaz sokar avciliginda ilk ureme boyu goz onunde tutuldugunda 6 numara ignenin agiz acikligindan daha buyuk agiz acikligina sahip ignelerin kullanimi onerilebilir.

Utilization of A Bioluminescent Pattern in the Encircling Gillnet Fisheries

Reviews in Fisheries Science (2010)

Uğur Altınağaç Uğur Özekinci Adnan Ayaz Özcan Özen Alkan Öztekin

To investigate the relationship between bioluminescent patterns and targeted fish species that cause this pattern, encircling gillnet sampling was conducted in shallow water (< 12 m) on moonless nights between February 2007 and December 2008 in the northern Aegean Sea, Turkey. The bioluminescent patterns of the targeted species Atlantic bonito, Sarda sarda, bluefish, Pomatomus saltatrix, and salema, Sarpa salpa were distinctive enough to identify the species. Although not a target species, round sardinella, Sardinella aurita, also exhibited a unique bioluminescent pattern to differentiate schools of that species from the other species. Bioluminescence "signature" of fish species was found to be an important tool in locating and identifying targeted fish species in the small scale encircling gillnet fisheries.
