  Performance of artificial neural networks and traditional methods in determining selected growth parameters of Alburnus sellal Heckel, 1843

  Ozcan, Ebru Ifakat

  In this study, predictions were made on the growth performance of Alburnus sellal Heckel, 1843 from the Munzur River using back propagation artificial neural networks and ANN algorithms. Statistical growth models used in fish biology and results obtained from artificial neural networks were compared. A total of 239 samples were used in this comparison. It was determined that the population is distributed across age groups 0–VII. The relationship between length and weight was calculated as W = 0.0046L3.198 for all individuals. The von Bertalanffy growth parameters were calculated for all individuals: Lt = 21.93 [1 – e–0.158 (t + 2.11)]; Wt = 102.29 [1 – e–0.158 (t + 2.11)]3.198. The growth performance index (Ф’) value was 1.880 for all individuals. The condition factor varied between 0.479 and 1.115 for females and between 0.533 and 1.076 for males. The Mean Absolute Percent Error (MAPE) statistic was used, which is a widely used method to measure the accuracy of the predictions made. It was determined that ANNs MAPE (%) values were better than MAPE values calculated for the length–weight relationship and von Bertalanffy growth function models for A. sellal. This study shows that ANNs can be used as an alternative useful method for predicting population parameters. ANN models are therefore an effective tool to describe fish growth parameters. They have been found to be a useful predictive tool. The developed models can be used to predict future sustainable fish management.

  Gündoğdu, Sedat; Kutlu, Banu; Özcan, Tahir; Büyükdeveci, Ferhat; Blettler, Martin C. M.

  Microplastic pollution in aquatic ecosystems presents an emerging environmental threat that can have adverse effects on ecology, endanger aquatic species, and result in economic damage. Despite the numerous studies reporting the presence of microplastics in marine environments, research into their presence in freshwater systems or inland waters remains limited. This study aimed to assess the level of microplastic pollution transported by the Munzur and Pülümür Rivers and some small rivers that flow into the Uzunçayır dam lake, which is the confluence of the Munzur and Pülümür Rivers in Türkiye. Samples were collected from 23 stations, with the concentration of microplastics ranging from 0.01 MP/m3 at P-4 station to 28.21 MP/m3 at P-10, a station located near a city. Microplastics comprise four types: fiber, film, fragment, and glitter. The average size of microplastics was 1.46 ± 0.05 mm, with the average size of fibers, films, fragments, and glitter-type microplastics being 1.58 ± 0.07 mm, 1.23 ± 0.10 mm, 1.21 ± 0.11 mm, and 0.78 ± 0.16 mm, respectively. The most frequent polymers were polyethylene (31.8%), polystyrene (21.1%), and polypropylene (10.5%). Despite being considered remote and less populated rivers compared to other river systems in Türkiye, all sampling sites showed varying concentrations of microplastics.

  Some Heavy Metals Accumulation in Tissues in Capoeta umbla (Heckel, 1843) from Uzuncayir Dam Lake (Tunceli, Turkey)

  Ural, Mesut; Yildirim, Numan; Danabas, Durali; Kaplan, Olcay; Yildirim, Nuran Cikcikoglu; Ozcelik, Mehtap; Kurekci, Eylem Funda

  Concentrations of metals were determined in the gills, liver, kidney, heart and muscle in Capoeta umbla caught from six stations from the Munzur River system. Metal concentrations in the tissues tended to vary significantly among stations (p < 0.05). Liver (Cu, 10.10 +/- A 0.23-23.03 +/- A 9.37 ppm; Zn, 14.67 +/- A 3.01-21.82 +/- A 2.39 ppm; Cd, 18.04 +/- A 4.56-52.69 +/- A 10.65 ppb and Fe, 28.87 +/- A 6.78-115.11 +/- A 34.87 ppm) and kidney (Cu, 1.80 +/- A 0.25-3.70 +/- A 0.62 ppm; Zn, 20.81 +/- A 0.37-29.36 +/- A 0.70 ppm; Cd, 132.06 +/- A 5.29-639.51 +/- A 20.14 ppb and Fe, 24.40 +/- A 1.98-59.39 +/- A 1.97 ppm) tissues showed higher metal concentrations than other tissues. It seems that metal contamination in the river is too high for the health of fish and the people who eat them. The geographical locations of catch, season, nature of diet, and the size of fish used for analyses might lead to different metal concentration in the same fish species.

  Gulec, A. K.; Yildirim, N. C.; Danabas, D.; Yildirim, N.

  Haematological parameters are indicators of the response of the animal to the environment and used as reliable indicators of fish health status to detect physiological changes following different stress conditions. This study was carried out to evaluate some haematological and biochemical parameters of Cyprinus carpio caught in Munzur River, Tunceli, Turkey. The values of total red blood cell count (RBC), haematocrit (HCT), haemoglobin concentration (HGB), mean corpuscular volume (MCV), mean cellular haemoglobin content (MCH), mean corpuscular haemoglobin concentration (MCHC), platelet count (PLT), mean platelet volume (MPV), plateletcrit (PCT), platelet distribution width (PDW) were measured. Levels of amylase, high-density lipoprotein cholesterol (HDL-C), cholesterol (CHOL), albumin (ALB), total protein (T-PROT), direct bilirubin (D-BIL), total bilirubin (T-BIL), gamma glutamyle tranferas (GGT), urea, creatinine, glucose (GLU), triglycerides (TRIG), uric acid (Uric-A), sodium, potassium, calcium, phosphorus and iron, chlorine were determined as 1.02 10(12)/L, 17.90 %, 11.72 g/L, 198.00 fL, 166.82 pg, 89.50 g/dL, 112.80 10(9)/L, 8.06 fL, 0.055 %, 17.59 fL, 87.20 U/L, 220.24 mg/dL, 767.40 mg/dL, 1.60 g/dL, 4.68 g/dL, 1.83 mg/dL, 3.046 mg/dL, 12.00 U/L, 9.20 mg/dL, 0.72 mg/dL. 504.40 mg/dL, 381.00 mg/dL, 2.76 mg/dL, 134.20 mmol/L, 1.90 mmol/L, 13.78 mg/dL, 17.96 mg/dL, 262.60 g/dL, 81.80 mmol/L, respectively. We assume that variation in values of blood indices may be a defensive mechanism against pollution.

  Kayim, Murathan; Öksüz, Abdullah; Özyilmaz, Ayse; Kocabas, Mehmet; Can, Erkan; Kizak, Volkan; Ates, Mehmet

  In present study, the proximate composition, fatty acid profile and mineral content of wild brown trout living in Munzur river (Tunceli/Turkey) were investigated. The average level of protein, lipid, moisture and ash content of muscle of the wild brown trout was calculated to be 17.48, 2.3, 77.8 and 1.5 %, respectively. Thirty fatty acids were identified in this study. Identification of the fatty acid was carried out with gas chromatography-mass spectrometry (GC-MS). The total polyunsaturated fatty acids (PUPA) were found the highest fatty acid followed by that of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). Docosahexaenoic acid (DHA, C22:6n3) and eicosapentaenoic acid (EPA, C20:5n3), linolenic acid (LNA, C18:3n3) and linoleic acid (LA, C18:2n6) were found to be predominant fatty acids in PUFAs with the percentages of 11.25, 6.82, 6.30 and 4.88, respectively. The ratio of n3/n6 and DHA /EPA was calculated to be 4.55 and 1.65, respectively. Twelve elements were determined in this study. Determination of elements was performed with ICP-AES. P and K were the predominant element among the minerals analyzed and calculated to be 1305.56-2967.06 and 1908.68-1220.10 mg kg(-1) in muscle-skin of the wild brown trout, respectively.

  EVALUATION OF ENVIRONMENTAL POLLUTION AT MUNZUR RIVER OF TUNCELI APPLYING OXIDATIVE STRESS BIOMARKERS IN CAPOETA TRUTTA (HECKEL, 1843)

  Yildirim, N. C.; Benzer, F.; Danabas, D.

  Aim of this study was to determine the extent of pollution in the Munzur River in Turkey was determined. The antioxidant (reduced glutathione (GSH), glutathione peroxidase (GSH-Px) catalase (CAT)) and the oxidant (MDA) status of hepatopancreas, gills, muscle, heart and kidney tissues of C. trutta were chosen as bioindicators. The fish samples were caught from contaminated (Station I) and uncontaminated (Station II) stations in Munzur River during April 2010. GSH levels were lower in gill, muscle and heart of the C. trutta collected at the contaminated station (p<0.05). The MDA levels were significantly higher in gill, muscle, kidney and heart of the C. trutta from the contaminated station (p<0.05). The CAT activity was significantly increased in the gill tissue at the contaminated station (p<0.05). GSH-Px activity was significantly decreased (p<0.05) in gill, muscle, kidney and heart tissues samples from C. trutta collected at the contaminated station compared to those collected from the uncontaminated station. Overall, the results demonstrate that alteration in the antioxidant enzymes, glutathione system and induction of lipid peroxidation reflects the presence of pollution, which may cause oxidative stress in the C. trutta from Munzur River. The results provide evidence those enzymatic and non-enzymatic biomarkers of oxidative stress.

  Use of Biochemical Markers in Capoeta trutta (Heckel, 1843) for the Assessment of Aquatic Pollution in Munzur River, Tunceli, Turkey

  Yildirim, N. C.; Danabas, D.; Ergin, C.

  The potential utility of biomarkers for monitoring both environmental quality and the health of organisms inhabiting polluted ecosystems has received increasing attention during the recent years. In this study. it was aimed to investigate the possible effect of pollution on biochemical parameters of Capoeta trutta captured in two environments with different levels of pollution in Munzur River, Tunceli, Turkey. One of them, hereby named reference site, there is no sewage discharge. Other side is denominated as polluted site is characterized by discharge of domestic sewage. Levels of amylase, alkaline phosphatase, lactate dehydrogenase, high-density lipoprotein cholesterol, cholesterol, albumin, total protein, direct bilirubin, total bilirubin, gamma-glutamyl tranferase, aspartate aminotransferase, alanine aminotransferase, urea, creatinine, glucose, triglycerides and uric acid were checked in blood samples. Plasma biochemical changes showed significantly differences between reference and polluted sites in alkaline phosphatase, lactate dehydrogenase, high-density lipoprotein cholesterol, cholesterol, alanine aminotransferase and glucose values. These results indicate that both domestic waste water and agricultural activities can alter the serum biochemical contents of Copeata trutta fish in Munzur River. Continuous production of pollutants resulting in impaired ability to respond to different environment stress factors and diseases. Present groups of researchers suggest that pollution levels should be monitored regularly.

  Levels of copper in liver, muscle and gill tissues in Capoeta trutta (Heckel, 1843) from Munzur River, Turkey

  Danabas, D.; Benzer, F.; Kaplan, O.; Yildirim, N. C.

  Heavy metal pollution of waters is a major environmental problem. Due to their toxicity, long persistence, bioaccumulative and nonbiodegradable properties in the food chain, heavy metals constitute a core group of aquatic pollutants. Capoeta trutta is an economically important fish and the object of significant commercial fishery in the Munzur River. Levels of Cu were measured in samples of the muscle, gill and liver tissues of C. trutta from Munzur River. In liver copper levels were higher at Station I (6.15 mg kg(-1)) polluted by domestic waste than Station II (5.48 mg kg(-1)) (P<0.05). The highest copper level (7.25 mg kg(-1)) was measured in muscle tissue at Station II. There was found no statically differences between stations in gill and muscle (P>0.05). It is suggested that ecological condition of freshwater fish and contamination levels in Munzur River must be regularly monitored.

  Fishes are largly used for the assessment of aquatic environment quality and are accepted as bioindicators of environmental pollution. This study evaluated haematological and biochemical responses of Capoeta trutta captured in Munzur River, Tunceli, Turkey. Blood and biochemical parameters (Sodium (Na), Potassium (K), Calcium (Ca), Phosphorus (P), Chlorine (Cl) and Iron (Fe)) were determined. The values of Red Blood Cell (RBC) Haemoglobin (Hb), Haemotocrit (Ht), Haemoglobin Concentration (MCHC), Platelet Count (PLT), Mean Platelet Volume (MPV), Plateletcrit (PCT), Platelet Distribution Width (PDW) from examined haematological parameters were found as 0.67+/-0.09 10(12) L(-1), 13.5+/-0.90 g dL(-1), 14.78+/-0.19%, 218.40+/-4.29 fL, 194.75+/-15.36 pg 108.52+/-1.09 g dL(-1), 34.12+/-5.89 10(9)L(-1), 11.92+/-1.65 fL, 0.061+/-0.01% and 19.77+/-1.71 fL, respectively. The values of Fe, Cl, P, Ca, K and Na from examined biochemical parameters were determined as 91.75+/-28.27 g dL(-1), 92.00+/-4.02 mmol L(-1), 13.20+/-1.26mg dL(-1), 11.65+/-0.74 mmol L(-1), 1.30+/-0.21 mmol L(-1) and 132.5+/-3.90 mg dL(-1) respectively. Observation of blood parameters allows the most rapid detection of changes in fish after the exposure to xenobiotics. It can conclude that hematological and biochemical parameters could be ranked as possible biomarkers of pollution.
