Öğe A new fish species for the Northern Aegean Sea Fauna; Aulopus filamentosus (Bloch, 1792)(Ege Univ, 2006) İşmen, Ali; Yigin, Cigdem; Cakir, FikretIn this study, a new record is given in order to fill the gap to some extent, with respect to the fish fauna of the Aegean Sea. A single specimen was sampled among commercial catches from the North Aegean Sea, Babakale coasts in February 2005. It is species, distributed along Aegean Sea from Izmir coasts to Babakale coasts. In study, morphological characteristics and fin formulas was determined with detail.Öğe Effect of marination and smoking on lipid and fatty acid composition of thornback ray (Raja clavata) and spiny dogfish (Squalis acanthias)(Springer, 2011) Colakoglu, Fatma Arik; Ormanci, Hasan Basri; Cakir, FikretThe effects of different processing methods (marinated and smoked) on proximate compositions and fatty acids of thornback ray (Raja clavata) and spiny dogfish (Squalis acanthias) were investigated. Total lipid content was 3.39% in thornback ray and 5.90% in spiny dogfish. The lipids of raw fish consisted mainly of polyunsaturated fatty acids in thornback ray and saturated fatty acid in spiny dogfish. The n-3/n-6 ratio of thornback ray (3.78) was higher compared to spiny dogfish (2.87). After processing, water content decreased significantly while crude protein, lipid, and ash contents increased in both fishes. In general, processing techniques significantly (p < 0.05) affected fatty acid fractions; in both species, SFA content increased, MUFA and PUFA content decreased. In addition, after processing n-3/n-6 ratios increased although total n-3 and n-6 contents decreased. The results indicated that heat treatment and acidic medium during processing had considerable affects on the proximate and fatty acid composition of the final products. Marinated and smoked products prepared from both fish species offer a balanced fatty acid composition for human nutrition. In terms of fresh and processed products, while the spiny dogfish appears to have a higher PUFA content, the thornback ray is a richer source of EPA + DHA.Öğe Investigation of the Effect of Different Immersion Times of Anchovy Fillets in Liquid Smoke Flavoring on Color by Image Analysis(Taylor & Francis Inc, 2020) Cakir, Fikret; Ayvaz, ZaydeThis study aimed to monitor the color changes of anchovy during the hot smoking process. For hot smoking, liquid smoke flavoring (LS) was used as an alternative to traditional smoking. The change in color was determined using the computer-based imaging system (CBI).L*, a*, andb*values were measured when anchovy samples were raw, after brining, after LS immersion, and after cooking. Various immersion times of 1, 2, and 3 minutes were tested, and resulting groups were coded as 1LS, 2LS, and 3LS, respectively. It was concluded thatL*, a*, andb*values of the smoked groups did not exhibit any statistically significant difference after immersion (p> .05). Interestingly, the changes in color parameters after cooking were found to be statistically significant (p< .05). Group 1LS had a lighter color than the other LS groups upon cooking. The Delta E value of the samples also increased during the process. During the smoking process of anchovies, no color changes as a result of salting and dipping in liquid smoke solutions for different durations were observed until the final cooking step. The results of this study can help in improving the processing, preservation, and marketing aspects of smoked anchovy by controlling the color properties. Since anchovy is a small fish, smoking by traditional methods is quite challenging. Therefore, LS applications are economical and practical for these kinds of species. Although there have been studies related to the use of LS on anchovies, no research has monitored their color change.Öğe Mass mortality in endangered fan mussels Pinna nobilis (Linnaeus 1758) caused by co-infection of Haplosporidium pinnae and multiple Vibrio infection in canakkale Strait, Turkey(Taylor and Francis, 2021) Kunili, Ibrahim Ender; Erturk Gurkan, Selin; Aksu, Ata; Turgay, Emre; Cakir, Fikret; Gurkan, Mert; Altinagac, UgurPurpose: Pinna nobilis (fan mussel) is one of the most important endemic bivalve molluscs in the Mediterranean and mass mortality events were observed in these mussels in recent years. In this study, we report mass mortalities caused by Haplosporidium pinnae, which has been spreading in the Mediterranean for 3 years, and reached the C¸anakkale Strait, which is the entrance of the Marmara and the Black Sea. Material and methods: Field observations during sampling and subsequent histopathological, biochemical, genetic, and microbiological analyses were carried out. Results: These analyses showed that H. pinnae infection spread among the natural beds of P. nobilis, causing severe tissue damage and oxidative stress. Our phylogenetic analyses suggested that the parasite spread through the Mediterranean much faster than thought. The results showed that vibriosis originating from Vibrio coralliilyticus, Vibrio tubiashii, Vibrio mediterranei, and Vibrio hispanicus, acted together with H. pinnae in infected individuals and caused death. Conclusion: It is highly probable that the spread of H. pinnae to the Sea of Marmara and the Black Sea may occur earlier than expected, and it was concluded that mass deaths were caused by co-infection with H. pinnae and a geographically specific marine pathogen that can infect P. nobilis populations.Öğe Microbiological quality of seafood in the Dardanelles, Turkey(2006) Colakoglu, Fatma Arik; Ozen, Ozcan; Cakir, FikretIn this study, bacteriological analyses of fish (finfish and shellfish) quality between the landing point at wholesale fish market and seafood retail stores in Dardanelles region of Turkey were compared in 2004. Fish samples (N = 200) from the seafood retail store were found to be significantly (p<0.05; t-test) more contaminated than those of the wholesale fish market. Microbiological analysis showed that the total bacteria counts ranged between 1.0×102 and 3.9×105 cfu g-1 in the wholesale fish market and between 1.2×102 and 5.8×107 cfu g-1 in the retail seafood stores. Coliform bacteria counts ranged between<101 and 2.4×10-1 cfu g-1 in the wholesale fish market and between <101 and 3.2×105 cfu g-1 in the retail seafood stores. Fecal streptococci varied between <101 and 4.9×103 cfu g-1 in the wholesale fish market and between<101 and 3.2×105 cfu g-1 in the retail seafood stores. These results showed that fish sold at local retail seafood stores were either not stored in hygienic conditions or fish were contaminated during the transportation from the wholesale fish market to retail seafood stores. © 2006 Asian Network for Scientific Information.Öğe Molecular investigation of nematodes isolated from three economical fish species taken from Canakkale (Turkiye) fish market(Ege Univ, Fac Fisheries, 2023) Aldik, Ruhay; Cakir, Fikret; Yayintas, Ozlem TongucThis study was based on the molecular identification of endoparasites sampled from three economically valuable fish species caught from the waters of the Canakkale (Turkiye). Subjected samples in the study were from chub mackerel (Scomber japonicus Houttuyn, 1782), anchovy (Engraulis encrasicolus Linnaeus, 1758), and bogue (Boops boops Linnaeus, 1758) without gender discrimination. The nematode parasites obtained from the samples were sent to molecular diagnostic laboratories in alcohol and the results were interpreted. As a result of the study, Anisakis typica (Diesing, 1860) Baylis, 1920 and Anisakis pegreffii Campana-Rouget and Biocca, 1955 were isolated from the chub mackerel fish and Anisakis pegreffii species were also isolated from anchovy and bogue. This parasite was the most isolated nematode parasite among all nematodes.Öğe Seasonal variation of some heavy metal pollution with environmental and microbiological parameters in sub-basin of Kocabas Stream (Biga, Canakkale, Turkey) by ICP-AES(Springer, 2007) Yayintas, Oezlem Tonguc; Yilmaz, Selahattin; Tuerkoglu, Muhammet; Colakoglu, Fatma Arik; Cakir, FikretWaste water pollution in industrial areas is one of the most important environmental problems. Heavy metal pollution, especially chromium species in waste water sources from tannery affects our lives. Kocabas Stream is located in south-west Marmara region and Biga town is positioned in the sub basin on the stream. This water source functions as the water for irrigation in agriculture, drinking water for animals and for human use. Thus, this study is of great importance. Waste water pollution can affect all ecosystems and human health by directly or indirectly as in food chain. The concentration of heavy metals (Pb, Cd, Cu, Zn and Cr) were pre-analysed by ICP-AES method in water samples taken from sub-basin of Kocabas stream. In the results of these analyses, concentrations of the metals except chromium were founded at the limit value. But the total concentration of the Cr was found at high levels of between 0.0082 +/- 0.0001 and 5.7231 +/- 0.0921 mg l(-1) over the limit value (0.05 mg l(-1); WHO, EPA, TSE 266 and inland water quality classification) at sampling points very close to tannery factories. Also physicochemical and microbiological parameters of Kocabas Stream were determined. The effects of the experimental results on environment were investigated.Öğe The awareness of staffs of water product shops about sanitation(Ege Univ, 2006) Cakir, Fikret; Colakogu, Fatma Arik; Berik, NerminThe diseases that are caused due to consumption of water products are serious problems all around the world. The education and knowledge about hygiene is the most important factor to avoid these health problems. According to that, 89 people, who work on these products directly in Canakkale, were questioned to determine their awareness about sanitation. As a result of this poll, 43.82 % of the people said that they had passed through a health control before being accepted to their jobs. 61.54 % of these controlled staffs gave samples of their throat and feces for being tested. On the other hand, rest of the people gave sample of only one of them. Moreover, it is decided that only 35.96 % of the workers know the infection ways of microorganisms. In generally, their appearances are satisfactory in terms of hands, clothes and hairs. In addition to that, all employees answered questions about hygiene of themselves and working place correctly. Consequently, it is concluded that the people, who are working on food products at city center of Canakkale, do not have enough knowledge about sanitation, which is very important on human health, and it is established that the rules about cleanliness are not put into practice efficiently.Öğe The evaluation of fish consumption in Canakkale(Ege Univ, Fac Fisheries, 2006) Colakoglu, Fatma Ank; İşmen, Ali; Ozen, Ozcan; Cakir, Fikret; Yigin, Cigdem; Ormanci, Hasan BasriFish products are an important diet in human consumption because of its animal protein source. In spite of the increasing population and the problems in balanced diet, fish products are not enough consumed in our country. In this study, in order to determine fish consumption habit a public survey was carried out on 680 people in Canakkale, an important fishing and aquaculture farming area. Survey results showed that the most people prefer to consume red poultry (47,5 %), fish (29,85 %) and red meat (22,05 %) respectively. The consumption rate of fish was horse mackerel (Trachurus trachurus), anchovy (Engraulis encrausicolus), sardina (Sardina pilchardus) and seabream (Sparus auratus) respectively. As the consumption form, it was established 65 % of people prefer to consume fish as fresh, for instance as a fried (45,73 %) or grill (39,08 %). Most of the families (87,46 %) consumed 1-6 kg fish in a month.
