Öğe A PRELIMINARY BIODIVERSITY SURVEY IN THREE SHIPWRECKS IN THE DARDANELLES (MARMARA SEA, TURKEY)(Parlar Scientific Publications (P S P), 2017) Ozalp, H. Baris; Alparslan, Mustafa; Okudan-Aslan, Emine Sukran; Aysel, Orkun; Aysel, VeyselIn this study macro aquatic biota inhabiting on three different shipwrecks in the canakkale Strait were investigated during the winter of 2010-2011 and the summer of 2014-2015 (Nov. 2010 -Sep 2015). One of the shipwrecks is strongly dominated by gorgonian corals while others had only a variety of algae and fish; 5 anthozoans, 2 echinoderm, 1 tunicate, 33 fish and 31 macroalgae species were determined. Visual census techniques were used for evaluation of fish assemblages around the sites. Based on faunal characteristics, the shipwrecks could be classified as three different groups.Öğe A preliminary biodiversity survey in three shipwrecks in the dardanelles (Marmara Sea, Turkey)(Parlar Scientific Publications, 2017) Ozalp, H.

Baris; Sagir-Odabasi, SerpilAn invasive commercial, veined whelk Rapana venosa (Valenciennes, 1846) is first recorded in 1946 around Novorossiysky Bay (Russia), Black Sea. This gastropod has been collecting since 1994 in front of Gelibolu (Canakkale, Turkiye). It is possible that they enter this region from Black Sea where the nearest population survive through both shipping activities and natural dispersion. R. venosa is known as predatory gastropod which kill impotant commercial bivaves such Mytilus galloprovincialis (Lamarck, 1819) and Pecten jacobaeus (Linnaeus, 1758). R. venosa especially, feeds on the mussels beds in this region. They are freely hunted by scubadiving and air supply diving systems all yearÖğe BALIKLARDA KAN GLUKOZUNU ETKİLEYEN BAŞLICA FAKTÖRLER(Erciyes Üniversitesi, 2008) Çelik, Ekrem Şanver; Aslan, Ayhan; Alparslan, MustafaBalıklarda kan glukoz düzeyini çevresel ve biyolojik faktörler önemli derecede etkileyebilmektedir. Biyolojik faktörlerin başında balık türü, populasyon, üreme ve cinsiyet gelirken çevresel faktörlerin başında ise suyun özellikleri, sudaki toksik ve kirletici maddeler, mevsim ve yıllık döngü gelmektedir. Balıklarda gözlemlenen kan değerlerinin doğru bir şekilde yorumlanması için onları etkileyen faktörlerin bilinmesi ve göz önünde bulundurulması gerekmektedir. Bu makalede, başlıca faktörlerden balık türü, üreme, mevsim, su sıcaklığı, hastalık, ağır metal ve pestisitlerin bazı balık türlerinde kan glukoz düzeyine etkileri ortaya konulmuş ve bu faktörlerin kan glukozunu etkilediği sonucuna varılmıştırÖğe ÇANAKKALE BOĞAZI İÇİN YENİ BİR KAYIT: Luvarus imperialis RAFINESQUE, 1810 (PISCES: Luvaridae)(2008) Irmak, Erhan; Alparslan, MustafaÇanakkale Boğazı'nın Güzelyalı Sahili'nden 21 Şubat 2005 tarihinde, 171 cm tam boya sahip 89,750 kg ağırlığında büyük bir dişi Luvarus imperialis Rafinesque, 1810 bireyi yakalanmıştır. Çanakkale Boğazı'ndan ilk kez bildirilen türün morfometrik ve meristik özellikleri belirlenmiştir. İncelenen örnek Piri Reis deniz müzesinde saklanmaktadırÖğe Çanakkale boğazı ve Yöresinde İstilacı-Ekonomik bir gastropod Rapana venosa (Valenciennes, 1846): Biyoekolojisi ve avcılığı(2006) Alparslan, Mustafa; Özalp, H. Barış; Odabaşı, Sağır SerpilYayılmacı bir oluklu deniz salyangozu olan Rapana venosa (Valenciennes, 1846) Karadeniz'de Novorossiysky Körfezi'nden (Rusya) ilk kez 1946 yılında kaydedilmiştir. Yine (Gelibolu) Çanakkale Boğazı'nda 1994 yılından beri avcılığı yapılmaktadır. En yakın populasyonların olduğu Karadeniz'den hem gemicilik faaliyetleri hem de doğal yayılımcı olarak bu bölgeye girdiği muhtemeldir. R. venosa, Mytilus galloprovinciaiis (Lamarck, 1819) ve Pecten jacobaeus (Linnaeus, 1758) gibi ekonomik önemli çift kabuklu yumuşakçaların üzerinde beslenen bir predator tür olarak bilinir. Özellikle, bu bölgede midye yatakları üzerinde beslenmektedir. Avcılığı tüm yıl boyunca nargile ve tüplü dalışlar ile serbest bir şekilde yapılmaktadır.Öğe Çanakkale Boğazı'na ait bazı meteorolojik parametreler ve bunları yöre balıkçılığı üzerine etkileri(2003) Alparslan, Mustafa; Tekinay, Ahmet Adem; Sağlam, MemişBu araştırmada, Çanakkale Boğazı'ndaki iklim koşullarının en önemli parametreleri olan rüzgar hızı (m/sn), fırtınalı gün sayısı (17.2 m/sn ve üzeri), kuvvetli rüzgarlı gün sayısı (10.8-17.1 m/sn), en hızlı rüzgar yönü, deniz suyu sıcaklıktan, sisli gün sayısı, yağmurlu gün sayısı ve hava basıncı irdelenmiştir (1991-2000 yıllan arası ile son 75 yılın ortalamaları).Öğe Çanakkale' de (Karacaören ve Kepez) toplanan midyelerde (Mytilus galloprovincialis Lamarck) bazı ağır metal düzeylerinin araştırılması(1997) Egemen, Özdemir; Alparslan, Mustafa; Sunlu, UğurBu çalışma, Çanakkale'de Karacaören ve Kepez kıyılarında toplanan midyelerde (Mytilus galloprovincialis Lamarck) birikim gösteren kurşun, kadmiyum, bakır, çinko gibi ağır metallerin düzeylerini saptamak amacıyla gerçekleştirilmiştir. Örnekleme İlkbahar 1997 - Kış 1998 tarihleri arasında belirtilen iki istasyonda mevsimsel olarak yapılmıştır. Atomik Absorpsiyon Spektrofotometresi ile yapılan analiz sonuçlarına göre kurşun (Pb) 0.55-0.88 ug/g; kadmiyum (Cd) 0.03-0.09 ug/g; bakır (Cu) 0.12-0.30 ug/g; çinko (Zn) 5.95-9.91 ug/g yaş ağırlık olarak saptanmıştır. Örneklerdeki ağır metal düzeyleri istasyonlara ve mevsimlere göre farklılık göstermektedir. Midyelerde saptadığımız birikim miktarlarının insan sağlığı açısından zararsız düzeyde olduğu tespit edilmiştir.Öğe Determination of some nutritional compositions of roe samples of the edible sea urchin Paracentrotus Lividus (Lamarck, 1816) in the Dardanelles (Marmara Sea)(Natl Inst Science Communication-Niscair, 2015) Kizilkaya, Bayram; Ozalp, H. Baris; Turker, Gulen; Alparslan, Mustafa; Tekinay, A. AdemIn this study, the nutritional composition of gonad samples of Paracentrotus lividus collected from three different stations in the Sea of Marmara (Dardanelles) and the Northern Aegean Sea, Bozcaada Island during the summer season of 2012 was investigated. As a purpose of the research, the effect of total carotenoids and free radical-scavenging activity assay of three different extracts (methanol, acetone and chloroform extracts) have been determined. Total carotenoids were found to range between 131 and 179 mu g/g of sea urchin. The current study shows that the highest inhibition was found as 99.1 (%) in methanolic extract sampled from Tuzburnu (the first station). Macro (Ca, Na, K and Mg) and micro (Cu, Fe, Mn and Zn) mineral composition of urchins was specified by ICP-OES. Results show that sea urchin was found to be rich in total carotenoids, antioxidant capacity, macro and micro minerals.Öğe Distribution and Morphology of the Colonial Scleractinian Madracis pharensis (Cnidaria, Anthozoa) in the Dardanelles (Marmara Sea, Turkey)(Inst Zoology, Bas, 2015) Ozalp, H. Baris; Alparslan, MustafaThe benthic communities in the Dardanelles were investigated with scuba diving and manta-tow techniques between 2011 and 2013 at 200 stations with a depth between 1 and 50 m. In these studies, the scleractinian Madracis pharensis (Heller, 1868) was collected from coralligenous and rocky habitats at five different sites at depths between 20 and 39 m. The ecological features of the colonies were examined in situ. The present paper reports the species occurrence and reveals the habitat characteristics of the species for the first time from this area. With this new record the known global distributional range of the species has been updated and the knowledge on anthozoan ecology along the Turkish coasts was enhanced.Öğe Fisherman's shelters around Çanakkale Strait, Turkey(Middle East Technical University, 2007) Alparslan, Mustafa; Özalp, Hasan BarişNorthwestern Turkey is divided by a complex waterway that connects the Black Sea to the Sea of Marmara and the Aegean Sea. The Turkish Straits, comprising the Çanakkale Strait, the Strait of Istanbul and the Sea of Marmara and are unique in many respects. There are 24 fisherman's shelters around the Çanakkale Strait and have very different structures. The first duty of the fisherman's shelter is to serve all manner of fishing vessels. The fisherman's shelters, both for fishery and for the acitivites of the ministry to be fulfilled, have a vital status and importance. Such places not only serve as a sheltering, safekeeping and service area for fisherman's vessels, but also as the first point to which the fishermen's catch has been put. Because of these characteristics, the inspectorships done by the Ministry of Agriculture and Rural Affairs are mostly carried out in these areas. Although our fisherman's shelters are sufficient in number, some of them need to be developed their infrastructures and superstructures.Öğe Scleractinian diversity in the Dardanelles and Marmara Sea (Turkey): morphology, ecology and distributional patterns(Walter De Gruyter Gmbh, 2016) Ozalp, H. Baris; Alparslan, MustafaAlthough marine research on anthozoans began at the end of the 1800s with some reports on the occurrence in Turkey, comprehensive knowledge about their biotic features remains limited. This study is the first detailed diversity assessment of scleractinian corals inhabiting the Turkish waters. The surveys conducted on rocky habitats between 2011 and 2014 around the Dardanelles and Marmara Sea provided the distributional data of nine corals, five of which (Caryophyllia inornata, Paracyathus pulchellus, Polycyathus muellerae, Phyllangia mouchezii, Leptopsammia pruvoti) were recorded for the first time from the above mentioned regions. During the surveys carried out at 200 stations down to 50 m depth, a total of 1072 scuba dives were made and the ecological features of habitats, physical characteristics of coral species and an updated list of corals as a contribution to the scleractinian fauna of Turkey were provided. The abundance rate of Polycyathus muellerae and Cladocora caespitosa in Eceabat and Dardanos regions was higher than at the other stations.Öğe The first record of Cladocora caespitosa (Linnaeus, 1767) (Anthozoa, Scleractinia) from the Marmara Sea(Tubitak Scientific & Technological Research Council Turkey, 2011) Ozalp, Hasan Baris; Alparslan, MustafaThe Scleractinian Cladocora caespitosa is reported for the first time from the Marmara Sea, Turkey. Five colonies of the elliptical Cladocora caespitosa were discovered at 7 m by scuba divers around Posidonia oceanica beds colonising a substrate of sand and rock. The colonies' characteristics were recorded with underwater apparatus with a close-up device and with a video system. The present paper provides the new updated area of the species on the Turkish coast.Öğe The research of protein and radioactivity levels of Patella coerulea LINNAEUS which is located around Urla(1997) Alparslan, Mustafa; Kumru, Mehmet N.Patella coerulea LINNAEUS has been thought protein source and therefore collected from around the Bay of Urla, Turkey. Total nitrogen fat and dampness parameters were determined. Nitrogen levels are 16.925 total (N)% in Zeytinalani, 14.96 total (N)% in Karantina, 17.63 total (N)% in Iskele, 13.72 total (N)% in Balikhova and total 13.13 (N)% in Karaburun. Activity of 137Cs, 40K, 226Ra, 228Th and gross gamma radioactivities of the samples were determined using a well type scintillation gamma spectrometer. The content of 137Cs, 40K, 226Ra, 228Th radioactivity varies from 10 to 20 Bq/kg, 354 to 489 Bq/kg, 0.36 to 0.62 Bq/kg and 0.14 to 0.37 Bq/kg respectively.
