Öğe Amino acid and biochemical composition of Banded Carpet Shell (Polititapes rhomboides, Pennant, 1777), collected from the Çardak Lagoon, Turkey(United Arab Emirates Univ, 2023) Vural, PervinBetween January and December 2019, banded carpet shell (Polititapes rhomboides, Pennant 1777) were gathered from cardak Lagoon (canakkale Strait). The length value was found to range from 32.92 to 36.37 mm, weight between 7.90 and 11.75 g, condition index from 4.44 to 8.70, and meat yield was found to be ranging from 11.95% to 24.95%. Negative allometry was determined in the W/L relationship of P. rhomboides. The main meat component of P. rhomboides was moisture (54.70-65.57%) and protein (52.89-62.10%) with the other components being carbohydrate (10.95-21.30%), lipid (12.79-17.18%) and ash (7.69-19.93%). The correlation between moisture and carbohydrate was positive, whereas the correlation between moisture and protein was negative (p<0.05). The present study not only informs us on composition but also recommends consumption of the species since it is easier to market and consume. Arginine amino acid was found to be the highest in quantity, which was followed by glutamic acid, serine, methionine, alanine, and aspartic acid.Öğe An Assessment of the Cultivation Potential and Suitability for Human Consumption of Mediterranean Mussels (Mytilus galloprovincialis Lamarck, 1819) from the Yalova Coast of the Marmara Sea(Kastamonu Üniversitesi, 2023) Acarlı, Sefa; Vural, Pervin; Yıldız, HarunThis study aimed to determine into potential suitability of juvenile Mediterranean mussel (Mytilus galloprovincialis) for cultivation and human consumption collected from various stations (Kapaklı, Çınarcık, Koru, and Deveboynu) along the Yalova coast of the South Marmara Sea during the spring season. Specifically, meat yield, condition index, moisture content, density of fouling organisms on the shells, and heavy metal concentrations (copper, zinc, mercury, cadmium, lead, and arsenic) were analysed. The average meat yields for Çınarcık, Deveboynu, Kapaklı, and Koru were found to be 24.51±2.96, 21.72±3.92, 23.75±2.31, and 21.54±4.01, respectively. Similarly, the average condition index were found to be 7.29±1.16, 6.02±0.97, 7.30±0.77, and 5.94±1.39 for Çınarcık, Deveboynu, Kapaklı, and Koru, respectively. The average shell component index for Çınarcık, Deveboynu, Kapaklı, and Koru were detected that 72.06±2.75, 74.39±4.13, 69.99±2.55, and 74.68±4.54, respectively. Additionally, the average moisture contents were found to be 82.63±1.95, 83.34±3.23, 84.02±1.82, and 83.40±4.17 for Çınarcık, Deveboynu, Kapaklı, and Koru, respectively. The statistical analysis revealed significant differences (p<0.05) in these parameters among the stations. Moreover, the quantities of competitive and fouling organisms, such as polychaetes and barnacles, were found to be highest in the Deveboynu and Koru stations. It has been determined that copper, zinc, mercury, and lead levels of the mussels are suitable for human consumption in all stations. However, arsenic values exceeded legal limits in Çınarcık, Koru, and Deveboynu, and cadmium values exceeded legal limits in all stationsÖğe Annual Reproductive Cycle and Meat Yield of the Wedge Clam Donax trunculus Linnaeus, 1758 from Black Sea(Springer Int Publ Ag, 2024) Yildiz, Harun; Acarli, Sefa; Vural, Pervin; Gunduz, FettahThe study aims to determine the reproductive cycle, the condition index, meat yield, shell component index, shell thickness index and gonad index of bivalve Donax trunculus inhabiting the Kefken-Babal & imath; location on the Black Sea in relation to environmental parameters between November 2013 and October 2014. Its gonadal development began in November. D. trunculus was in the inactive stage during autumn. Spawning was observed from May (18 degrees C) to August (28 degrees C). Sex ratios were not equal and number of males was higher during the study period (1.13:1) with one hermaphrodite individual only. Being synchronous between sexes based on histological analysis, the reproductive cycle consists of six stages. The study showed that the most ideal period to harvest of D. trunculus was between December and May, especially when the meat yield and condition index were determined to be highest.Öğe Antioxidant radical scavenging capacity and total carotenoid content of narrow-clawed crayfish (Pontastacus leptodactylus, Eschscholtz, 1823) in Atikhisar Reservoir (Çanakkale, Türkiye)(Walter De Gruyter Gmbh, 2023) Acarli, Sefa; Kizilkaya, Bayram; Vural, Pervin; Berber, Selcuk; Kale, Semih; Acarli, DenizIn this study, antioxidant radical scavenging capacity and total carotenoid content in the meat and shells of Pontastacus leptodactylus were investigated. Concerning the antioxidant scavenging effect, the highest IC50 values were found to be 388.77 mg g(-1) and 155.53 mg g(-1) for females and males in July and March, respectively. The mean IC50 values of the meat were calculated as 239.83 mg g(-1) and 105.21 mg g(-1) for females and males, respectively. The mean total carotenoid content in the meat was found to be 14.35 and 12.78 mu g g(-1) for females and males, respectively. The results indicated that crayfish meat had antioxidant radical scavenging capacity and was rich in carotenoid content.Öğe Association between the Crab, Nepinnotheres pinnotheres (Linnaeus, 1758), and the Endangered Species Fan Mussel, Pinna nobilis (Linnaeus, 1758), from the Aegean Sea, Turkey(Adem Yavuz Sonmez, 2019) Acarli, Sefa; Vural, Pervin; Oktener, AhmetPinna nobilis, commonly known as the fan mussel or pen shell, is an endemic species in the Mediterranean Sea. The fan mussel population has recently been significantly endangered along the Mediterranean coast, mainly due to diseases. However, it has a critical role in the ecological system of the throughout the coasts of the Mediterranean. Therefore, it is important to investigate the interactions between P. nobilis and their enemies, parasites, symbiont in the ecological environment. Pea crabs are small crustacean and symbionts in a variety of invertebrates. They inhabit the mantle cavities of bivalve. The association between the pea crab, Nepinnotheres pinnotheres ( Decapoda), and P. nobilis (Bivalvia) from the Aegean Sea, Turkey was examined in this study. The crab samples were collected off Urla Karantina Island, Izmir Bay, Aegean Sea. The biometric characteristics of bivalve and crab in this coexistence were analyzed. 80% of P. nobilis was occupied by N. pinnotheres. The weight of pea crabs was recorded between 0.01 g and 3.87 g.Öğe Çardak Bölgesi'ndeki (Lapseki-Çanakkale) Akdeniz midyesinin (Mytilus galloprovincialis, L.1819) farklı derinliklerde büyüme ve yaşama performansları(Çanakkale Onsekiz Mart Üniversitesi, 2011) Vural, Pervin; Yıldız, HarunBu çalışma Ağustos 2009-Mart 2010 tarihleri arasında Çanakkale Boğazı'na bağlı Lapseki-Çardak bölgesinde yapılmıştır.

In the 1960s, C. gigas was brought to Europe for aquaculture in the Mediterranean and Black Sea regions from Japan and Canada. The Turkish waters are the part of the Mediterranean Sea, which is the world’s most invaded sea. The invasion of alien species results from marine transportation and aquaculture activities of non-native species. A heavy maritime traffic is also present in the Marmara Sea, which connects the Black Sea and Mediterranean Sea. The identification of the invasive species and their distributions is very prominent in terms of protecting natural habitat and monitoring the effects of invasive species. In this study, 30 individuals, morphologically identified as C. gigas, were collected from Bandırma bay. The genomic DNAs were extracted from each sample’s muscle tissue using universal salt extraction method. Partial sequences of COI and 16S Mitochondrial DNA loci of the sample DNAs were obtained for species identification. The sequences were searched against the database and results were retrieved from BLAST. All the sequences obtained in this study showed significant similarity with the C. gigas sequences present in the database (E=0). The sample sequences resulted in 9 different haplotypes for the COI locus (hd: 0.5296 and variance: 0.01256±0.112) and 5 different haplotypes for the 16S rDNA locus (hd: 0.2529, Variance: 0.01076±0.104). The results of this study provided the first molecular evidence for the presence of non-native Pacific oyster individuals in the Marmara Sea.Öğe Growth and survival performances of Mediterranean mussel (Mytilus galloprovincialis, Lamarck, 1819) on different depths in Cardak lagoon, Dardanelles(Adem Yavuz SÖNMEZ, 2015) Vural, Pervin; Yildiz, Harun; Acarli, SefaThis study was conducted at Cardak Lagoon of Dardanelles between August 2009 and March 2010. The average initial and final length of the Mediterranean mussel (Mytilus galloprovincialis Lamarck,1819) from different depths (0.5 m, 5 m, 10 m) were measured as 9.75± 0.81 mm - 41.21±3.42 mm, 9.76±0.87 mm - 39.64±2.90 mm, 9.95±0.75 mm - 38.13±2.70 mm and 0.11±0.03 g - 6.56±1.82 g, 0.11±0.03 g - 5.83±1.23 g, 0.11±0.02 g - 4.39±1.00 g, respectively. On the growth of mussels, monthx depth interaction (P = 0.221) and depth (P = 0.078) did not show a significant effect, but months were found to be effective (P = 0.00). The survival rates of the mussels at 0.5 m, 5 m, 10 m depth were determined as 87%, 87% and 76%, respectively. The difference of the survival rates of the mussels with respect to different months was significant (P = 0.011). Nevertheless, the depth had no effect upon the mussel survival rate (P = 0.091). It was confirmed that especially the particulate organic matter (POM) detected in water as well as the particulate inorganic matter (PIM) played a significant role in addition to the slight role that the salinity had on the growth performance of the mussels.Öğe Influences of different collector materials on Mediterranean Mussel, Mytilus galloprovincialis L. 1819 in the Dardanelles.(Adem Yavuz SÖNMEZ, 2013) Yıldız, Harun; Lök, Aynur; Acarlı, Sefa; Serdar, Serpil; Küçükdermenci, Aysun; Berber, Selçuk; Vural, PervinThe present study is carried out in Kilya Bay (in the Dardanelles) between February 2002 and February 2004. The purpose of this study was to determine the most suitable collector material, time to collect mussel seed, and the growth rate. In the first three months of the study, different collector materials (net rope, polypropylene rope, sisal rope, and jute rope) were deployed in the water column. Spat recruitment was not varied between collector materials (p>0.05). When resistance of ropes were compared against the effects of water, it was found that net rope was most suitable for the mussel seed collection. Net collectors were deployed in February, March, April, May, June, and January. Mussel spat settlement was observed throughout the study, however between collectors, spat attachment was significantly different between months (p<0.05). The higher attachment period was observed in February and April. These results showed that mussel reproduction period was all year round and first attachment individuals reached marketable (<50 mm) size in 1.5 year.Öğe Monthly Variation of Biochemical Composition of Lagoon Cockle (Cerastoderma glaucum, Bruguiere, 1789), from cardak Lagoon (Turkey)(Springer Int Publ Ag, 2022) Vural, PervinIn the present study, lagoon cockle samples (Cerastoderma glaucum, Bruguiere, 1789) were collected from cardak Lagoon (canakkale Strait) between January 2017 and December 2018. Its morphology, condition index, meat yield, length-weight relationship and biochemical characteristics (protein, lipid, carbohydrate, moisture and ash) were examined and were found values of length, weight condition index and meat yield were in the range of 31.69-40.58 mm, 12.62-22.81 g, 3.48-7.61 and 10.40-17.14%, respectively. W/L relationship of C. glaucum exhibited a negative allometry. A positive correlation was found between meat yield and condition index (p < 0.05). Main component of C. glaucum meat were moisture (56.73-69.52%) and protein (59.34-67.88%) with carbohydrate (3.49-19.33%), lipid (9.65-16.47%) and ash (9.39-13.20%) being other components. Moisture was positively correlated with carbohydrate but negatively correlated with protein (p < 0.05).Öğe Monthly variation of fatty acids, lipid quality index and metal content of Pontastacus leptodactylus (Eschscholtz, 1823) in Atikhisar Dam Lake (Çanakkale, Türkiye)(Springer, 2024) Berber, Selçuk; Acarlı, Sefa; Bayraklı, Barış; Kale, Semih; Kızılkaya, Bayram; Vural, Pervin; Acarlı, DenizThis study aims to investigate the metal content, fatty acid composition, lipid quality, and potential health risks of Pontastacus leptodactylus crayfish inhabiting Atikhisar Dam Lake. The research covers a 12-month period and includes both male and female individuals. The study investigated the metal content of crayfish specimens. In female individuals, the metal concentrations were ranked as Fe > Zn > Al > Cu > Mn > Se > As > Hg > Cd > Pb, while in male individuals, the ranking was Fe > Al > Zn > Cu > Mn > Se > As > Hg > Pb > Cd. The results demonstrate that Atherogenicity Index (AI) values for both genders range between 0.21 and 0.31, and Thrombogenicity Index (TI) values fall within 0.14 and 0.20. This indicates that crayfish meat is composed of healthy and high-quality fatty acids. In male individuals, omega-3 values range from 25.28 ± 0.380% to 28.34 ± 0.430%, and in female individuals, they vary from 22.98 ± 0.195% to 28.73 ± 0.871%. These findings underscore the absence of significant health risks associated with mercury levels in crayfish meat. Monthly meal calculations reveal that consuming female crayfish at an average of 4.35 servings per month for adults and 2.24 servings per month for children presents no health hazards. Similarly, the consumption of crayfish meat at an average of 5.29 servings per month for adult males and 2.72 servings per month for male children is deemed safe for health. Based on these results, the lipid quality of both male and female individuals from this species is found to be beneficial, as confirmed by risk–benefit assessments. © The Author(s) 2024.Öğe Monthly variation of micro- and macro-element composition in smooth scallop, Flexopecten glaber (Linnaeus, 1758), from the Çardak Lagoon (Çanakkale Strait, Turkey)(Ege University Faculty of Fisheries, 2021) Vural, Pervin; Acarlı, SefaThe present study investigated the total elemental composition (Fe, Cu, Mn, Zn, Al, S, B, Na, Mg, K, Ca, P, S) in smooth scallop (Flexopecten glaber) meat collected monthly in the Çardak Lagoon (Turkey) in 2017- 2018. Considering the distribution of elements in terms of quantity during the year, the elements were sorted as S> Na> K> P> Mg> Ca> Fe> Zn> Mn> Al> B> Cu> Se and the heavy metals were below the detection limit. Although the elements were at their highest values during autumn and summer, they were at their lowest values during spring and winter. The differences between the months in terms of Fe, Mn, Mg, and Ca elements were found to be statistically significant (p <0.05). It was determined that the element composition of smooth scallop meat was suitable for consumption in terms of the area where it is collected and is beneficial for health when consumed in the amounts recommended by FAO/WHO, and CODEX. The Hazard Quotient (THQ) and the Hazard Index (HI), which was conducted to evaluate the health risks of consuming smooth scallop, were found below 1 all months. For this reason, smoth scallop consumption in this region does not have any negative effects on human health.Öğe Monthly variations of protein and amino acid composition of the smooth scallop Flexopecten glaber (Linnaeus 1758) in the Cardak Lagoon (Lapseki-Canakkale)(Station Biologique de Roscoff, 2021) Vural, Pervin; Acarlı, SefaIn the present study, the total protein and amino acid composition of smooth scallop (Flexopecten glaber) meat sampled every month for one year was determined in the Çardak Lagoon (Turkey). The lowest protein level in smooth scallop meat (57.41% dry weight, dw) was found in December, whereas the highest protein level was observed in April (67.62% dw). Essential amino acid concentrations ranged from 16.60 to 20.82 g.100 g-1 dw, while non-essential amino acid concentrations ranged from 36.03 to 46.68 g.100 g-1 dw. Among essential amino acids, phenylalanine was dominant. The highest essential amino acid contents were observed in winter and spring, while the highest non-essential amino acid contents were observed in summer and autumn. The differences in monthly essential amino acids and non-essential amino acid values were statistically significant (p < 0.05).Öğe Morphometric characteristics of invasive species Magallana gigas (Thunberg, 1793) in Bandırma Bay, Marmara Sea(2023) Acarlı, Sefa; Yıldız, Harun; Vural, PervinTürkiye’s seas are the scene of the spread of invasive species in the entire Mediterranean basin due to the marine transportation of alien species and intensive aquaculture activities. In order to protect the natural ecosystem and track invasive species’ effects, these species must first be accurately identified and their distribution areas specified. The alien species, Magallana gigas (Pacific oyster), has introduced along the Turkish coasts. This study was carried out to determine the morphometric characteristics of Magallana gigas in the Bandırma Bay-Balıkesir between November 2013 and October 2014. Shell length varied between 68.08 mm (February) and 93.14 mm (April) during the year. Shell height was measured at the lowest 41.90 mm in February, and the highest 59.46 mm in June. Shell width was 35.80 mm in November when the study started, and it decreased gradually and reached its lowest value in February. W/L relationship of M. gigas was calculated as W=0.411×L2.653(R2=0.064) This study includes knowledges on morphometric relationships for the Pacific oyster which is crucial for the management of fisheries, aquaculture activities and native species (Ostrea edulis).Öğe Relationship Between Environmental Factors, Meat Quality and Biochemical Composition Bearded Horse Mussel (Modiolusbarbatus, Linnaeus 1758) Ayvalik Bay, Balikesir- Turkey(Springer Science and Business Media Deutschland GmbH, 2023) Acarlı, Sefa; Karakoç, Şenay; Vural, PervinConsumption of the bivalve and gastropod species from the Mollusca phylum has been increasing recently due to the high quality of their nutrient content compared to the terrestrial species. Especially bivalve species have an important share within the world total aquaculture production amount. The bearded horse mussels, Modiolus barbatus, (Linnaeus 1758) are consumed particularly in Europe. This study has been conducted from April 2016 to March 2017 in Kumru Cove in Ayvalık Bay, Balıkesir (N 39º18’07.6” and E 26º38’01.1”). Environmental conditions such as temperature, salinity, chlorophyll-a, particulate organic matter and particulate inorganic matter were monitored during the sampling period. The meat yield, condition index, shell component index, biochemical composition values were measured and calculated monthly during the study period. The condition index and meat yield values varied by 4.87–10.22 and 17.04 -23.37%, respectively. A negative relationship between protein and carbohydrate and also between carbohydrate and total lipid, and ash and moisture were found in the study (P ≤ 0.05). Temperature fluctuation had effect on salinity, condition index, shell component index, carbohydrate and moisture while seston influenced meat yield (P ≤ 0.05). The morphometric relationship of length/width and length/weight showed a negative allometry, while the isometric relationship was found between length and height.Öğe Seasonal variation in the condition index, meat yield and biochemical composition of the flat oyster Ostrea edulis (Linnaeus, 1758) from the Dardanelles, Turkey(Taylor & Francis Ltd, 2011) Yildiz, Harun; Berber, Selcuk; Acarli, Sefa; Vural, PervinThis study was conducted in Dardanelles between October 2007 and August 2009 when condition index, meat yield, biochemical compositions and environmental parameters of seawater were investigated and the study area was found to have available conditions for cultivation. Investigation of the study area showed a positive correlation in particular among condition index, seasonal variation of temperature, protein, fat and chlorophyll-a; a negative correlation was seen between them and carbohydrate value. It was clear from the two years study that the most ideal period for oyster harvest is April and August especially when condition index was maximum followed by a winter with no oyster yield is available in terms of the related processes involving oyster cultivation.Öğe Shell Composition Analysis of European Flat Oyster (Ostrea edulis, Linnaeus 1758) From Marmara Sea, Türkiye: Insights Into Chemical Properties(Adem Yavuz SÖNMEZ, 2024) Kızılkaya, Bayram; Yıldız, Harun; Vural, PervinThe chemical structure of Ostrea edulis (O. edulis) shells was investigated in this work. The study determined zero charge points (PZC) of Ostrea edulis shells. The shell surface charge status is indicated by the PZC value. It was found that the shell PZC value was 8.30. The shells were subjected to Energy Dispersive X-Ray Spectroscopy (EDS) analyses and scanning electron microscope (SEM) pictures. The main structure of calcium carbonate (CaCO3) is made up of carbon, oxygen, and calcium atoms, which were found in the largest quantities based on the EDS data. The structure of CaCO3 was supported by Fourier Transform Infrared Spectroscopy (FT-IR) analysis. As part of the study, X-Ray Diffraction (XRD) investigations were conducted, and it was found that the shell structures are primarily composed of an aragonite and CaCO3 mixture. As is well known, CaCO3, which makes up roughly 94% of the shell, is the primary constituent of bivalves’ shells. This research offers a thorough examination of the chemical makeup of O. edulis shells. This study is thought to serve as the foundation for further research on the biological and chemical characteristics of marine species.Öğe Temporal variability in biochemical composition and morphometric parameters of cultivated Mediterranean mussels (Mytilus galloprovincialis) in Çanakkale, Türkiye(Elsevier, 2024) Acarli, Sefa; Vural, Pervin; Yildiz, HarunIn recent years, there has been a growing interest in bivalve and gastropod species (Mollusca phylum) due to their high nutritional value compared to terrestrial organisms. Bivalve species, in particular, hold significant potential for both aquaculture and fishing industries worldwide. Among shellfish, mussels play a crucial role in aquatic ecosystems. Parameters such as meat yield and condition index are essential for determining consumption strategies of bivalve species. Thus, this study focused on monthly collections of Mediterranean mussels (Mytilus galloprovincialis) from & Ccedil;anakkale Gelibolu Ilgardere Mediterranean Mussel Cultivation Farmers between March 2019 and February 2020. During this period, analyses were conducted for condition index, meat yield, shell component index, as well as protein, carbohydrate, lipid, and ash content. The temperature variations in the study area aligned with seasonal changes maximum value and minimal value were recorded as 8.7 degrees C in March and 27.3 degrees C in July. Salinity values ranged from 15.2 parts per thousand in November and January to 24.01 parts per thousand in December. The length of mussels ranged from 52.54 mm to 68.53 mm, with total weights ranging from 11.18 g to 25.37 g. The length-weight relationship of Mediterranean mussels was determined as Weight = 0.0002 * Length(2.80)(6). Condition index, meat yield, and shell component index exhibited significant variations across months (P < 0.05). There was no relationship between these parameters and environmental factors. Fluctuations in protein content were observed, with the lowest recorded in May (41.88 %) and the highest in November (61.19 %). Lipid, carbohydrate, and ash content ranged between 12.49 % and 18.59 %, 9.69 % and 34.31%, and 6.95 % and 18.06 %, respectively. Overall, it can be concluded that aside from the summer months, the harvesting and consumption of cultivated mussels are more suitable in terms of meat quality and biochemical profile.
