Item Alterations of Growth Performance and Blood Chemistry in Nile Tilapia (Oreochromis Nuoticus) Affected by Copper Sulfate in Long-Term Exposure(Turkish Journal of Fisheries and Aquatic Sciences 15: 487-493 (2015), 2015) Mutlu, Ekrem; Aydın, Seyit; Kutlu, BanuThe objective of this study was to evaluate the effects of copper sulfate (CuSO4.(5 H2O)) on the Nile tilapia (Oreochromis niloticus). Median (LC50) and minimum (LC1O) lethal concentrations of copper sulfate on Nile tilapia were determined via acute tests. LC50 values of copper sulfate for the 48th, 72nd and 96th hours were 13.15, 12.95 and 12.85 mg/L, respectively. LC10 values of 12, 11 and 9.5 mg/L were obtained for similar exposure periods (48th, 72nd and 96th hours), respectively. The effects of 1.5 mg/L dose of copper sulfate on growth rate, gross clinical observations and blood biochemical parameters of Nile tilapia were evaluated after 35, 65 and 95 days of exposure periods. The differences of growth rates between control and copper sulfate-exposed groups were not significant (P>0.05) at the end of 35, 65 and 95 days. Continuous exposure of Nile tilapia to 1.5 mg/L concentration of copper sulfate in water solution for three periods (35, 65 and 95 days) decreased the total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose (except the elevation in the exposed group at the end of 95 days period), magnesium (Mg+²), calcium (Ca+²), iron (Fe+²), potassium (K+), sodium (Na+1), chloride (CI-) and phosphate values in serum. The cholesterol, low density lipid (LDL), triglyceride, globulin, creatinine, alkaline phosphatase (ALP), total bilirubin, direct bilirubin, uric acid and blood urea nitrogen (BUN) concentrations in the serum increased in copper sulfate-exposed fish.Item Alterations of Growth Performance and Blood Chemistry in Nile Tilapia (Oreochromis Nuoticus) Affected by Copper Sulfate in Long-Term Exposure(Turkish Journal of Fisheries and Aquatic Sciences 15: 487-493 (2015), 2015) Mutlu, Ekrem; Aydın, Seyit; Kutlu, BanuThe objective of this study was to evaluate the effects of copper sulfate (CuSO4.(5 H2O)) on the Nile tilapia (Oreochromis niloticus).

The basic 28 variables used to determine water quality were measured monthly at six stations. Taking into account the World Health Organization's drinking water standards, the water quality index (WQI) and Turkey's Ministry of Forestry and Water Affairs Surface Water Quality Regulations (SWQR) were used in determining the water quality. In addition, irrigation water quality was examined. For this, sodium absorption rates (SAR), sodium percentage and residual sodium carbonate (RSC) values were calculated. WQI values in the lake were found to be between 17.62 and 29.88. Water quality parameters did not exceed the recommended limit values in all months and at all stations. According to these values, the Saraydüzü Dam Lake water belongs to the 'very good' class in terms of drinking water quality. The results obtained showed that there were no nitrogen or phosphate inputs that could harm the ecosystem in the lake and that there were no low/insufficient ambient oxygen conditions resulting from excessive oxygen consumption during the degradation process of organic matter. All water quality parametres are well below the permissible limits except some heavy metals according to SWQR. Cu, Zn and Fe were found to exceed the limit values. The water quality of irrigation water was found to be good in terms of SAR and sodium percentage, whereas RSC was observed to have varying qualities during the year and not be suitable for irrigation in some months. According to results of factor analysis (FA), pH, temperature, electrical conductivity, suspended solid matter (SSM), biological oxygen demand (BOD), total hardness (TH),total alkalinity (TA), calcium, nitrate, ammonium, mercury and dissolved oxygen are the main variables responsible for the processes in the ecosystem.Pubmed Assessment of the potentially toxic element contamination in water of Şehriban Stream (Black Sea Region, Turkey) by using statistical and ecological indicators.(2021-10-01T00:00:00Z) Tokatli, Cem; Mutlu, Ekrem; Arslan, NaimeIn the present study, the spatial-temporal variations of iron, lead, copper, cadmium, mercury, nickel, and zinc accumulations in the water of Şehriban Stream (northern Turkey) were investigated. Water Quality Index (WQI), Heavy Metal Evaluation Index (HEI), Pearson Correlation Index (PCI), and Factor Analysis (FA) were used in analyzing the water quality. Sampling was performed in 12 stations on monthly basis between February 2019 and January 2020 (a hydrological year). The data showed that the Şehriban Stream had significantly high water quality characteristics and the investigated toxicants were not found as dangerous for health. Although there was a slight decrease in the water quality from upstream to downstream, the stream was found to have 1st class water quality in general. As a result of WQI and HEI, although it was determined that the water quality decreased slightly in autumn, the stream was found to be "A Grade - Excellent (<50)" and "Low Contamination (<10)," respectively. As a result of PCI, strong positive correlations were found between almost all the toxicants investigated here (p < 0.01). As a result of FA, 2 factors ("Agriculture - Forestry" and "Rock Structure") explained 86% of the total variance.Pubmed Assessment of the water quality of Bartın Kışla (Kozcağız) Dam by using geographical information system (GIS) and water quality indices (WQI).(2023-03-30T00:00:00Z) Şimşek, Arife; Mutlu, EkremThis study was conducted to evaluate the water quality of the Kışla (Kozcagiz) Dam located in the province of Bartın in the Western Black Sea Region of Turkey. Water samples were collected monthly from 5 stations for a year and analyses were conducted using 27 water quality parameters. The quality of the dam and the water quality parameters were evaluated using different indices in comparison to the limits determined according to the standards set by the World Health Organization (WHO) and Turkey Surface Water Quality Regulation (SWQR). Water quality index (WQI), organic pollution index (OPI), sodium adsorption ratio (SAR), magnesium adsorption ratio (MAR), permeability index (PI), and metal pollution index (MPI) were calculated and spatial assessment of pollution was made seasonally by making use of the geographic information system (GIS). A piper diagram was used in determining the facies of the water. The types of Ca-Mg-HCO predominated in the dam water. Moreover, statistical analyses were used in order to determine if there was a significant difference between the parameters. WQI results generally indicate that the water quality was good in all seasons; however, only in the autumn, sampling points S1 (101.58), S2 (100.59), S4 (102.31), and S5 (102.12) showed poor water characteristics. According to the OPI results, while winter and spring yielded good water quality, summer samples were lightly polluted and autumn samples were moderately polluted. Given SAR results, it can be stated that the water of Kışla Dam could be used as irrigation water. Considering the standards specified by WHO and SWQR, the parameters generally exceeded the threshold values, but the water hardness value was much higher than 100 mg L specified in SWQR as very hard water. The principal component analysis (PCA) results showed that the pollution sources were anthropogenic. Thus, for the dam water to not be affected by the increasing pollutant factors, it should be continuously monitored, and attention should be paid to the irrigation methods used in agricultural activities.Item Batıayaz Deresi (Samandağ) Su Kalitesinin Fiziko-Kimyasal Yöntemlerle Belirlenmesi(Türkiye Kıyıları 2012 Bildiriler Kitabı Cilt 2, 2012) Mutlu, Ekrem; Yanık, Prof. Dr. TelatAkdeniz’in kuzeydoğusunda bulunan Musa Dağı eteklerinden doğan Samandağ ilçesi girişinde Asi Nehri ile birleşerek Akdeniz’e dökülen, Batıayaz Deresi’nin su kalitesi özelliklerini belirlemek amacıyla gerçekleştirilen bu çalışmaya Haziran 2004 tarihinde başlanmış ve 12 ay boyunca yürütülmüş olup, su örnekleri aylık olarak toplanmıştır.

The diet containing 12.73 MJ digestible energy/ kg feed resulted in the best growth, blood parameters, and liver histology. Fish that consumed the 10.85 and 11.82 diets had similar weight gains, feed, and protein utilization as fish fed diets containing 13.69 or 15.06 MJ (p>0.05) but fish fed diets containing 13.69 or 15.06 MJ/kg had signs of hepatic lipidosis.Pubmed Evaluation of spatio-temporal variations in water quality of Zerveli stream (northern Turkey) based on water quality index and multivariate statistical analyses.(2019-05-03T00:00:00Z) Mutlu, EkremThis study of Zerveli stream, Kastamonu, aims to present an assessment of its water quality and to determine the basic factors having a significant effect on the water to identify how these factors account for variations in water quality. Samples of surface water were obtained on a monthly basis between December 2016 and November 2017 at 11 stations along the watercourse. According to these samples, 28 different water quality parameters determining the water quality were evaluated. The results were assessed with respect to the environmental water quality and irrigation water quality. For this purpose, the water quality index (WQI), sodium absorption rate (SAR), sodium percentage (%Na), and residual sodium carbonate (RSC) parameters were calculated. WQI values within the year ranged between 17.26 (excellent) and 223.05 (very poor). Based on the monthly mean values, the water quality was found to be good in December, February, July, and August and poor in the remaining months. Water quality tended to deteriorate the greater the distance from the water source. According to factor analysis (FA), salinity, pH, temperature (T), electrical conductivity (EC), suspended solid matter (SSM), chemical oxygen demand (COD), biochemical oxygen demand (BOD), SO, SO, NO-N, NO-N, NH-N, and Cl are the main variables responsible for changes in the ecosystem. According to analysis of the irrigation water quality, the stream was found to be suitable for irrigation in terms of SAR (1.07-3.25) and %Na (37.58-61.89) but problematic in terms of RSC (3.80-5.58) values.Publication Evaluation of spatio-temporal variations in water quality of Zerveli stream (northern Turkey) based on water quality index and multivariate statistical analyses.(2019-05-03T00:00:00Z) Mutlu, Ekrem; Mutlu, EThis study of Zerveli stream, Kastamonu, aims to present an assessment of its water quality and to determine the basic factors having a significant effect on the water to identify how these factors account for variations in water quality.
