Purpose: The aim of this study was to determine the histopathological changes that the mussels, which serve as important filters of the sea, cause in rat kidney tissue. Materials and Methods: In our study, 24 female (Wistar albino 6-10 week old rats) rats were used. First group (n: 6): fed with standard rat food, second group (n: 6): fed everyday with 4/5 mussels + 1/5 standard rat food; third group (n: 6): fed 4/5 mussels + 1/5 standard rat food every two days; Fourth group (n: 6): were formed with 4/5 mussels + 1/5 standard rat food to be given every three days. After the routine histopathological follow-up, all kidney tissue samples taken and control groups were analyzed with Hematoxylin-Eosin staining, and the nephrotoxic effect was immunoshistochemically with TGF-β and NF-κB and analyzed with a light microscope image analysis system. Results: Mussel-fed rats were found to cause inflammation in the kidney tissue, dilatation in the distal and proximal tubules, shrinkage in the glomeruli and degeneration in the tubular epithelium. In immunohistochemical staining, TGF-β and NF-κB immunoreactivity increased due to cells leading to inflammation and apoptosis. The nephrotoxic effect was quite high especially in rats given daily mussels. Conclusion: The mussel provided in unsanitary conditions may cause damage in kidney tissue from the excretory system organs due to excess consumption.

SEAWATER , *MUSSELS - Abstract
In this study, the microbiological quality of 536 mussel samples collected from 9 different stations in Çanakkale region and the sea water taken from each station were determined. It was determined that the highest total aerobic mesophilic bacterial count of mussel samples was at the Merkez İskele station (3.56 log cfu/g). However the highest E. coli presence was detected at Gelibolu station (1.99 log cfu/g). It was determined that the microbial loads of mussels were not statistically different between the stations where they were collected (P>0.05). A positive correlation was found between the total bacterial count of mussels and the total bacterial count of seawater they were collected (P<0.05). It was observed that the microbial load at Gelibolu and Lapseki stations was higher than other stations. In general, it was determined that mussels taken from different points of Hellespont, Çanakkale except Gelibolu and Lapseki region was within the legal limits. [ABSTRACT FROM AUTHOR]

In this study, the most suitable mantle part and host mussel species for pearl sac formation were determined. A total of 400 mussels, consisting of four different types (Unio terminalis, Potamida littoralis, Leguminaia wheatleyi and Anodonta pseudodopsis) were used. The average dorso-ventral lengths of the mussels were respectively; 7.89±0.25; 7.28±0.38; 10.68±0.27 and 11.14±0.34 cm. Mantle tissue slices in the size of 3×3 mm obtained from the pallial edge of mantle tissue were used as grafts. Two different mantle sections were identified for graft implantation, one being the mantle cavity and the other was incisions on the mantle tissue. At the end of the three-month pearl culture, the mantle cavity section was identified as the best graft implant site. U. terminalis was determined as the most successful species in terms of survival rate and pearl formation. P. littoralis was the second successful species and L. wheatleyi was the lowest among the species. This study is a guide for long-term pearl production on nacre thickness and quality which are considered important in pearl production.

In this study, antibacterial effect of koruk (unriped grape), lemon and pomegranate juice against Vibrio parahaemolyticus was investigated. For this purpose, approximately 107 CFU/g V. parahaemolyticus were inoculated into mussel samples. Inoculated mussel samples were treated with koruk, lemon and pomegranate juice for 0, 30, 60 and 90 minutes and stored at 4 °C for 6 days. During the storage period, V. parahaemolyticus number, pH and titratable acidity value were determined and evaluated in terms of sensory parameters. As a result of the research, the highest antibacterial effect was detected in the koruk juice groups (P <0.05). On the 0th day of the experiment, the number of V. parahaemolyticus in the groups that were applied koruk, lemon and pomegranate juice were decreased by 2.22-2.64; 1.58-1.85, and 1.44-1.71 log CFU/g, respectively. This downward trend continued on other storage days. Sensory evaluation revealed that pomegranate juice negatively affected the color and appearance of mussel samples (P <0.05). As a result, it has been determined that acidic acidifiers used in home applications, especially the koruk juice has a high antibacterial effect, and can be used for food safety in seafood.

- Abstract
NoVs, previously known as Norwalk-like viruses from the Caliciviridae family, are non-enveloped, positive-sense, single-stranded RNA viruses with icosahedral capsid symmetry. NoV infection causes both secretory and osmotic diarrhea. A few NoV particles are sufficient to produce infection. NoV is mainly spread by contaminated food and water. Direct person-to-person contact or contact with contaminated surfaces and fomites are also responsible for spreading the virus. In general, epidemic and pandemic outbreaks occur due to NoVs. Sporadic cases have also been reported. Outbreaks and sporadic infections have been reported to be resulting from consumption of NoV contaminated shellfish (e.g. mussel, oyster, and crab), soft red fruits (strawberry and raspberry), vegetables (lettuce, tomatoes and parsley), bakery products, delicatessen meats, salads, sandwiches, water and ice. NoV is responsible for more than half of nonbacterial diarrheal diseases around the world. Outbreaks of NoV originating from shellfish such as mussels and oysters are common in the world. It has been reported that shellfish grown in virus contaminated waters and seafood products prepared for consumption by infected individuals may play a role for outbreaks. Bivalve molluscan shellfish, such as mussels and oysters, can filter out large quantities of water as part of their feeding activities and, accumulate and concentrate viruses from shallow, coastal and river waters frequently contaminated with sewage. Depth, water temperature, precipitation, wind and salinity of the water in the mussel and oyster growing area are important factors for the prediction of outbreak risks. Shellfish has been reported to be important in the spread of foodborne diseases in developed and developing countries. In Turkey, 78 tons of black mussels per year are collected from sea for consumption. The presence of NoV in mussels indicates that this shellfish could also be an important contaminant for foodborne viral infections and outbreaks in Turkey. Monitoring the prevalence of NoV in shellfish collected from Turkey can be used to prevent outbreaks in touristic locations and to monitor the potential of Turkish seas for viral contaminations. In this study, the role of shellfish in viral gastroenteritis outbreaks associated with NoV and strategies for preventing virus transmission via shellfish are reviewed. [ABSTRACT FROM AUTHOR]

Objective: Among seafoods mussels are the most common ones that are mostly raw consumed raw. Bacterial contamination in foods that cause food poisoning are is known to be due to mainly storage and processhig conditions. Due to mussels' die taly specifications, them filter water and take in its toxic substances and microbial contaminants. Mussel bacterial load prior to consumption is important to demonstrate pollution levels of the hunting regions. Material and Method. In this study, black mussels (Mytilus galloprovincialis) hunted from seven different stations on two coasts of Dardanelles two coast (Asia: Çardak, Yapıldak, Sançay; Europe: Kilitbahii Eceabat, Çambumu, Gelibolu) were analyzed microbiologically in the months of February and June. Mussel samples were examined for total aerobic mesophilic bacteria (TAMB), coliform group bacteria, Escherichia coli, Staphylococcus aureus and Salmonella spp. Results: The mean colony count from all stations was; 54x105±1.6x106 cfu/g LAMB, 1.0x105±2. 6x105 cfu/g coliform group bacteria, 2.6x105±1.4x106 cfu/g E. coli, 2.2x105±1.3x105 cfu/g S. aureus respectively Salmonella spp. were not detected in any mussel samples examined. Black mussels hunted in June had significantly higher microbiological contamination for all bacteria than mussels hunted in February (p<0.0001). When we investigated two coasts as Anatolia (Çardak, Yapıldak, Sançay) and Europe (Kilitbahir, Eceabat, Çamburnu, Gelibolu) in two different periods; contamination on Europe coast was significantly higher for TAMB at february (p=0.01), at the same time S. aureus contamination was significantly higher at Anatolia coast (p=0.02). TAMB (p=0.004) and E.coli (p=0.005) count in samples on Anatolian coast were found to be significantly higher. [ABSTRACT FROM AUTHOR]

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2013, Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2013, Kirlenme dünyada önemli bir sorun olarak karşımıza çıkmaktadır. Kirlenmeye karşı önlemler alınabilmesi için öncelikle kirletici tiplerinin ve kirlenmenin seviyesinin belirlenmesi gereklidir. Kirlenmenin canlılardaki birikimi ve etkilerinin incelenmesi biyoizleme olarak adlandırılır. Biyoizleme yöntemleri biyobirikim gözlemi (Bioaccumulation monitoring: BAM) ve biyolojik etki gözlemesi (Biological effect monitoring: BEM) olarak ikiye ayrılabilir.Bu çalışma kapsamında Türkiye kıyılarındaki çeşitli noktalardaki kirlilik seviyelerinin ve etkilerinin belirlenebilmesi için biyoindikatör canlı olarak Akdeniz midyesi (Mytilus gallaprovincalis) kullanılmıştır. Kirletici olarak organik kirleticiler olan polisiklik aromatik hidrokarbonlar (PAH), poliklorlu bifeniller (PKB) ve organoklorlu pestisitler (OKP) araştırılmıştır. Aynı zamanda bu canlıların kirlenmeye karşı tepkileri fizyolojik (filtrasyon hızı), hücresel (lizozomal membran stabilitesi) ve biyokimyasal (enzim) biyogösterge yöntemleri uygulanarak incelenmiştir. Çalışma bölgeleri olarak Marmara, Bodrum ve Saros Körfezi seçilmiş ve bu noktalara midye transplantasyonu yapılmıştır. Ayrıca İstanbul Boğazı?ndan yerel midyeler toplanmış ve bu örneklere filtrasyon hızı, lizozomal stabilite, ve biyokimyasal biyogöstergeler uygulanmıştır. Marmara örneklerinde transplantasyon süresince, genel olarak incelen kimyasal seviyelerinde artış; Bodrum ve Saros örneklerinde ise azalma görülmüştür. Bu sonuçlara göre Marmara Bölgesi?nde genel bir kirlenme göze çarpmaktadır. Bodrum ve Saros bölgeleri için ise incelenen kimyasallar açısından önemli bir kirlenme olmadığı söylenmiştir. Biyokimyasal analizlerinde midyelerin sindirim bezlerinde 7-etoksirezorufin-O-deetilaz (EROD), glutatyon S-transferaz (GST) ve asetilkolin esteraz (AChE) aktiviteleri incelenmiştir. Sonuçlar incelendiğinde filtrasyon hızı ve lizozomal stabilite biyogösterge yöntemlerinin başta PAH ve PKB?ler olmak üzere kirleticiler tarafından olumsuz olarak etkilendiği görülmüştür. Biyokimyasal yöntemlerden elde edilen sonuçların önceki çalışmalarla çeliştiği belirlenmiştir. İlerleyen zamanlarda laboratuvar ortamında yapılacak kontrollü çalışmalarla bu durumun açıklanmasının önemli olduğu düşünülmektedir., Pollution in the aquatic enviroment is a major problem in the world. Bioindicator organisms are used to determine the levels of pollution as well as the effect of pollutants during the biomonitoring studies. In this study, Mytilus galloprovincialis (Mediterranean mussel) was selected as bioindicator organism. Biomonitoring methods (bioaccumulation monitoring:BAM; biological effect monitoring: BEM) were applied to different coastal areas of Turkey. Those are; a shipyard zone in Marmara, two marinas (Bodrum-Marina and Istanbul Marina) and a reference station in Saros Bay ?in northern Aegean?.Local mussels from Rumeli Kavağı, Istinye and Beşiktaş (İstanbul Strait) were also collected. The concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorinated pesticides (OCPs) were only determined in the tissues of transplanted mussels. Filtration rate (FR), lysosomal stability of mussels? blood cells and biochemical activities (enzymes) were examined in both transplanted and local mussels. In biochemical assays, ethoxyresorufin ?O- deethylase (EROD), glutathione S-transferase (GST) and acetylcholinesterase (AChE) activities were investigated. GST and EROD values for Saros and Istanbul Strait samples could not be evaluated because of their very low values and high standart deviations. In conclusion, a depuration was observed at Bodrum and Saros samples during transplantation period. A significant pollution was seen in Marmara region according to chemical analysis. In general, filtration rate and lysosomal stability are good indicators of pollution. On the other hand biochemical assays are relatively hard to apply in laboratory, and because the levels of enzymes are low in mussels, the evaluation of the results is difficult., Yüksek Lisans, M.Sc.

Considering the filtration capacity of mussels to qualitative particle selection, our study focused directly on ingested species by assessing mussel stomach content of various size classes (1-5 cm) over a year (August 97-June 98) rather than monitoring seawater samples. Different size of mussels (1, 2, 3, 4, 5 cm in length) was sampled monthly from the sides of fish cage floats in Urla-Izmir.

Bu çalışmada Ege Bölgesinde, İzmir Körfezinde doğal ortamda yetişen M. galloprovincialis tipi kara midyelerdeki arsenik (As), bakır (Cu), cıva (Hg), çinko (Zn), demir (Fe), kadmiyum (Cd) ve kurşun (Pb) birikimi 2008 yılı Ocak ? Aralık döneminde altı ayrı istasyondan her ay örnek toplanarak izlenmiştir.Alaçatı, Balıklıova, Bodrum, Bostanlı, Narlıdere ve Sasalı Bölgelerinden her ay toplanan midye örnekleri haşlanmış ve haşlanmamış olmak üzere iki farklı işlem uygulanarak incelenmiştir. Toplanan midye örnekleri ayıklandıktan sonra mikrodalga yakma sistemi ile ekstrakte edilerek ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer) cihazında metal konsantrasyonları analiz edilmiştir.Yapılan analiz sonuçları ve istatistiki değerlendirmelere göre haşlama prosesinin arsenik (As) ve cıva (Hg) elementleri konsantrasyonlarını düşürdüğü, diğer elementler üzerinde ise herhangi bir etkisi olmadığı görülmüştür.21.09.2008 tarih ve 27004 nolu resmi gazetede yayınlanan Su Ürünleri Yönetmeliğine göre midyelerde izin verilen toksik metal düzeyleri (Cd, Hg ve Pb) kuru madde bazında değerlendirildiğinde; bulunan değerlerin yasal limitler içerisinde olduğu ve halk sağlığı açısından tehlike oluşturmayacak düzeyde olduğu tespit edilmiştir. Yürürlülükten kaldırılan yönetmelikte (10.03.1995 tarih ve 22223 sayılı resmi gazete) midyelerde aranan toksik metaller gurubunda yer alan bakır (Cu) ve demir (Fe) konsantrasyonlarının yasal limitler içerisinde, arsenik (As) ve çinko (Zn) konsantrasyonlarının ise yasal limitlerin üzerinde olduğu görülmüştür. Buna göre; ortalama kadmiyum konsantrasyonu 0,86 ? 1,12 µg g-1; bakır konsantrasyonu 8,17 ? 13,30 µg g-1; demir konsantrasyonu 192,77 ? 252,65 µg g-1; kurşun konsantrasyonu 0,31 ? 0,89 µg g-1; çinko konsantrasyonu 115,07 ? 155,11 µg g-1; arsenikde haşlanmamış örneklerde 9,44 ? 15,94 iken haşlanmış örneklerde 6,31 ? 10,11 µg g-1; cıvada haşlanmamış örneklerde 0,07 ? 0,15 µg g-1 iken haşlanmış örneklerde 0,12 ? 0-22 µg g-1 olarak tespit edilmiştir.Anahtar kelimeler: Midye, Mytilus galloprovincialis, metal, iz element, ICP OES This thesis aimed to investigate the arsenic (As), copper (Cu), mercury (Hg), zinc (Zn), iron (Fe), cadmium (Cd), lead (Pb) concentrations of M. galloprovincialis type black mussel in Aegean region in İzmir. The mussel samples have taken from six different stations from January to December in 2008.The mussel samples, which were obtained in Alaçatı, Balıklıova, Bodrum, Bostanlı, Narlıdere and Sasalı stations and were collected each mounth, were analysed in two different applications. Some of the samples were boiled and the others were analysed uncooked. Firstly, samples were dissected and then samples digested with concentrated nitric acid by microwave digestion method. Heavy metal contaminant were determined by using ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometer) technique and the results are evaluated statistically.The results are demonstrated that the boiling process decreased the level of arsenic and mercury in the samples, while the others have not been effected from the boiling application.The data have been compared to Turkish sea food regulation which number is 27004, published at 21.09.2008. The result of this study shown that the heavy metal levels of mussel samples are in the permissible levels. These findings indicate that the levels of these element has not any affect to human health. Besides the regulation which is press 10.03.1995, although the copper and iron are in permissible levels, arsenic and zinc levels are out of the these limits. The ranges of concentrations of heavy metals found in collected samples were: cadmium (0.86 ? 1.12 µg g -1), copper (8.17 ? 13.30 µg g-1), iron (192.77 ? 252.65 µg g-1), lead (0.31 ? 0.89 µg g-1), zinc (115.07 ? 155.11 µg g-1). The arsenic and mercury level of the uncooked samples are found that 9.44 ? 15.94, 0.07 ? 0.15 µg g-1. When the samples were cooked with boiling, the level of these element levels decreased to 6.31 ? 10.11 µg g-1, 0.12 ? 0.22 µg g-1.Key words: mussel, Mytilus galloprovincialis, heavy metal, trace metal, ICP OES 152

Çalışmada her bir türe ait etlerin kimyasal kompozisyonları ve pH değerleri tespit edilmiştir. Bu dört farklı tür su ürünü etinin mısır yağı ile oluşturdukları emülsiyonların; emülsiyon kapasitesi (EK), emülsiyon viskozitesi (EV), emülsiyon stabilitesi (ES), emülsiyondan ayrılan yağ (EAY), emülsiyondan ayrılan su (EAS), emülsiyon özgül ağırlığı (EÖA) ve emülsiyon pH değerleri saptanmıştır. Her bir et çeşidinin %2.5 NaCl ve %0.50 K2HPO4 çözeltisiyle oluşturduğu ?et+çözelti? homojenizatlarının pH değerleri belirlenmiştir. Ayrıca, araştırmada kullanılan etlerin pişirme kaybı (PK), su tutma kapasitesi (STK) ve sızıntı kaybı (SK) gibi çeşitli özellikleri de tespit edilmiştir. Araştırmada kullanılan Ahtapot (Octopus vulgaris C.) etinin %81.10'u su, %12.80'i protein, %1.14'ü yağ ve %1.99'u mineral maddedir. Kalamar (IIIex coindetti V.) etinin %76.57'si su, %15.38'i protein, %0.97'si yağ ve %1.50'si ise mineral maddeden oluşmaktadır. Midye (Mytilus galloprovinciallis L.) etinin %79.51'i su, %10.80'i protein, %1.51'i yağ ve %1.16'sı ise mineral maddedir. Sübye (Sepia officinalis L.) etinin %76.24'ü su, %14.53'i protein, %1.83'ü yağ ve %1.83'ü ise mineral maddeden oluşmaktadır. Ahtapot, Kalamar, Midye ve Sübye etlerinin ortalama pH'ları sırasıyla 6.28, 6.49, 7.03 ve 6.73 olarak belirlenmiştir. Tuz-fosfat çözeltisi ilave edildikten sonra elde edilen homojenizatların pH değerleri yükselmiştir. Araştırmada kullanılan etlerin oluşturdukları emülsiyonların pH değerleri ise 7.32 ile 7.63 arasında değişim göstermiştir. Araştırmada kullanılan dört türe ait etlerin; kurşun, çinko, bakır, nikel, krom, kadmiyum, alüminyum, demir, kobalt, manganez, gümüş, baryum, kalsiyum, magnezyum, sodyum, potasyum, fosfor, bor, civa, selenyum ve kalay içeriklerine bakılmış olup, Midye eti çinko (p0.01), bu et çeşitleri diğerlerine kıyasla çok daha stabil emülsiyonlar oluşturmuşlardır. Ahtapot, Kalamar, Midye ve Sübye etleri kullanılarak oluşturulan emülsiyonların ortalama EÖA'ları sırasıyla, 0.8752 g/cm3, 0.8793 g/cm3, 0.9500 g/cm3 ve 0.8819 g/cm3`dür. Sonuç olarak, farklı tür su ürünü etlerinin çeşitli özelliklerinin ve oluşturdukları emülsiyonların, EK, EV, ES, EAS, EAY, EÖA gibi teknolojik özelliklerinin avantaj ve dezavantajları dikkate alınarak, bu etlerin yalnız veya çeşitli kombinasyonlar halinde emülsiyon et tipi ürünlerinin üretiminde kullanılabilecekleri belirlenmiştir., In this research, Octopus (Octopus vulgaris C.), Calamary (Illex coindetii V.), Mussel (Mytilus galloprovincialis L.) and Cuttlefish (Sepia officinalis L.) meats were used. Chemical compositions and pH values of each meat species were determined. Emulsion capacity (EK), emulsion viscosity (EV), emulsion stability (ES), oil separation (EAY), water separation (EAS), specific gravity (EÖA), and pH values of emulsions formed with corn oil and these four different meat species were determined. The pH values of slurries prepared with every meat species plus solution of 2,5% NaCl and 0.5% K2HPO4 were determined. Besides, various properties of these meat species, such as cooking loss (PK), water holding capacity (STK) and drip loss (SK) were determined. It was determined that the Octopus meat had 81.10% moisture, 12.80% protein, 1.14% fat and 1.99% ash. The calamary meat had 76.57% moisture, 15.38% protein, 0.97% fat and 1.50% ash. The mussel meat had 79.51% moisture, 10.80% protein, 1.51% fat and 1.16% ash. The cuttlefish (Sepia officinalis L.) meat 76.24% moisture, 14.53% protein, 1.83% fat and 1.83% ash. Average values pH values of the octopus, calamary, mussel and cuttlefish meats were determined as 6.28, 6.49, 7.03 and 6.73, respectively. Addition of salt-phosphate solution increased the pH values of the slurries. The pH values of emulsions prepared by the meats used in this study were determined to range between 7.32 and 7.63. Lead, zinc, copper, nickel, chrome, cadmium, aluminum, iron, cobalt, manganese, silver, barium, calcium, magnesium, sodium, potassium, phosphorus, boron, mercury, selenium and tin contents of the meats used in this study were determined. Mussel meat was found to be richer in zinc (p0.01) between the ES values of calamary and cuttlefish meats, which formed the more stable emulsions as compared to other meat species. Mean EÖA values of the emulsions formed with octopus, calamary, mussel and cuttlefish meats were determined to be 0.8752 g/cm3, 0.8793 g/cm3, 0.9500 g/cm3 and 0.8819 g/cm3, respectively. As a consequence, it was determined that these seafood meat species could be used in the formulation of emulsion type meat products, either each alone or in combination with each others by taking into account their advantageous and disadvantageous emulsion characteristics and technological properties such as EK, EV, ES, EAS, EAY, EÖA.

Elde edilen verilere göre, kullanılan hamsi ve ton balığının surimi üretimi için uygun olduğu bulunmuştur. Elde edilen ürünün besin değeri yüksek ve ekonomik olması, dondurularak uzun süreli depolanabilmesi ve' piyasaya sürekli ürün verilmesine olanak sağlaması nedeniyle toplum beslenmesine katkıda bulunacağı ve ülke ekonomisine büyük yarar sağlanacağı sonucuna varılmıştır. Anahtar Kelimeler: Surimi, Ton balığı, Hamsi, Karides, Midye, Deniz Ürünleri Technological Researches on Surimi Production from Anchovy and Tuna fish ABSTRACT Seafoods are important protein sources for human nutrition. They are the products which don't need investment expenses and easy to find and take very important place in most of countries economy. Surimi, is the frozen concentrate of the myofibrilar protein. Generally, fish meat is mechanically deboned, washed, minced, mixed with cryoprotectans, such as sugar, sorbitol and poly-phosphate, to improve texture and prevent the product from freezing denaturation and frozen. Surimi, validates uncommercial species and waste- meats, as well as some commercial species, for human consumption as this type of production credits to a longer storage. In this research, surimi, was produced by using waste meats obtained from canned tuna fish, anchovies smaller than 9 cm little shrimps, and mussels. From this point of view, meats were minced and mixed with each other in 14 different formulas. After adding ingredients they were stored in PVC containers at - 18°C for a year (0., 3., 6., 9., 12. months). During this period physical, chemical, microbiological, organoleptical and statistical analyses were applied and quality properties were investigated. According to the results, it was determined that the anchovy and tuna fish were suitable for surimi production. The products have high nutritional and economic value, can be frozen-stored for long periods of time and supply the market with a continous input In view of these aspects, surimi could be considered as an important product for nutrition of the community and the economy.
