Distribution of Fish Species in the Van Lake Basin
(Centenary University, 2016) Elp, M.; Atici, A.A.; Şen, F.; Duyar, H.A.
This study was carried out to determine the fish species of Van Lake Basin between in 2008-2012. Van Lake Basin is a closed basin that shaped approximately 2.3 % of Turkey. Because of closed basin character, the differences indicated in species diversity. Basin is rich in endemic species diversity with plant and animal species. This richness were reflected to fish species. All of the fish species naturally occurring in the lake basin are consist of endemic species. Alburnus tarichi, Alburnus timarensis, Barbus ercisianus, Capoeta cosswigi and Oxynoemacheilus ercisianus exhibited a natural distribution. Cyprinus carpio, Carassius gibelio, Gambusia holbrooki and Aphanius mento were constituted population from various water sources. In addition, escaped from fish farm sorvaccinated to water resources Oncorhynchus mykiss was unable to create the population. Barbus ercisianus and Capoeta cosswigi shown to create hybrid fish species in Zilan and Deliçay. Cyprinus carpio and Carassius carassius shown to create hybrid fish species in Nazik Lake. © 2016, Centenary University. All rights reserved.
Drinking Water Quality Properties of Ercis, Van-Turkey
(Centenary University, 2016) Atici, A.A.; Gültekin, A.; Şen, F.; Elp, M.
In this study, microbiological, physical, and chemical characters of drinking water supplied from city of Ercis were analyzed. Temperature, turbidity, conductivity, dissolved oxygen, biological oxygen demand, chemical oxygen demand, calcium, magnesium, total hardness, total alkalinity, free chloride, carbonate, bicarbonate, nitrite, nitrate, ammonia, phosphorus, zinc, copper, nickel, cobalt, cyanide, fluoride, aluminum, iron, potassium, manganese, molybdenum, silicon and microbiological parameters were analyzed in the laboratory. The results were evaluated according to “Turkish Regulation of Surface Water Quality Management, Turkish Water Pollution Control Regulations, TS 266, Turkish Regulation on Water Intended for Human Consumption”. © 2016, Centenary University.

First Record of Lernaea Cyprinacea (Crustacea: Copepoda) on Capoeta Capoeta (Actinopterygii: Cyprinidae) From Karasu Creek (Van) Eastern Anatolia
(Universitatea din Oradea, 2018) Koyun, M.; Atici, A.A.
In the present study, Lernaean parasite (Lernaea cyprinacea) or called cyclopoid copepod parasite was reported on the examined fish species captured from the Karasu Creek (Van, Turkey), in July 2014. Cyclopoid parasites were isolated from the external surface of fins, operculum and body surface of Capoeta capoeta. A total of 82 parasites were found in 20 fish caught. The prevalence of parasites were calculated as 65% and the intensities as 6.31%. The cyclopoid parasite was observed and measured by microscope observations. The morphological features of the parasite specimens and the pictures are given. © Biharean Biologist, Oradea, Romania, 2018.
First Report of Ligula Intestinalis (Cestoda: Pseudophyllidea) in Barbus Ercisianus (Cypriniformes: Cyprinidae) From the Nemrut Crater Lake, Turkey
(Centenary University, 2022) Önalan, Ş.; Atici, A.A.; Sepil, A.; Şen, F.
Van Basin has a rich geographical structure in terms of water resources and endemic fish species. In this study, Ligula intestinalis parasite, which is the host of Barbus ercisianus living in Nemrut Crater Lake, was recorded for the first time. The parasite was described molecularly as well as morphologically. In this context, a primer set was designed for molecular identification for the 28S rRNA gene region of L. intestinalis. Real-Time PCR results with the designed primers gave positive results in all parasite samples. The results were confirmed by a single peak (87) in the HRM analysis. © 2022, Centenary University.

Investigation of Water Quality Criteria of Drinking Waters in Center of Van, Turkey
(Centenary University, 2017) Çavuş, A.; Atici, A.A.; Şen, F.
In this study, it has been investigated whether different water resources, distributed to networks as drinking water in the center of Van, are appropriate to consumption according to physical, chemical and microbiological analyzes. Turbidity, electrical conductivity, temperature, dissolved oxygen, pH was measured in the water received from the network water. Biological oxygen demand, chemical oxygen demand, calcium, magnesium, total hardness, total alkalinity, chloride, carbonate, bicarbonate, nitrite, nitrate, ammonia, phosphorus, zinc, copper, nickel, cobalt, cyanide, fluoride, aluminum, iron, potassium, manganese, molybdenum and microbiological analyzes were analyzed at a laboratuary. The results were generally found to be appropriate for the values given in our country’s regulations on drinking water. © 2017, Centenary University. All rights reserved.
An Investigation on Systematic History and Distribution Areas of Tarek (Alburnus Tarichi (Güldenstädt, 1814))
(Instituto Internacional de Ecologia, 2021) Atici, A.A.; Elp, M.; Sen, F.
This study aimed to determine the distribution area of tarek (Alburnus tarichi (Güldenstädt, 1814)) and to define how it must be called according to the scientific name by evaluating its previous studies made by various systematisers and their reports on its distribution, and by comparing literature knowledge. The taxonomic characteristics of the collected samples were evaluated and several measurements and counts were taken on the samples; analfin origin 0-4 scales behind dorsal fin-base; 72-91 lateral line scales; 21-29 gill rakers; 7½-10 branched dorsal-fin rays and 10-12½ branched anal-fin rays. Body and caudal peduncle was moderately compressed. Body was covered by overlapping scales. Tarek has five different populations in the Basin. They are Van, Erçek, Nazik and Aygır Lakes and Koçköprü Dam Lake populations. The main living area of the tarek population is Lake Van; however, between May and June, mature individuals of tarek enter to tributaries of Van Lake. Some of them are Karasu, Bendimahi, Deliçay, Zilan, Karmuç, Sapur, Yanıkçay, Gevaş, Engil, Kurubaş and Akköprü Streams. At the end of study, it was concluded that tarek should be called as Alburnus tarichi (Güldenstädt, 1814) and it is an endemic fish species distributed only in Van Lake Basin. © 2021, Instituto Internacional de Ecologia.
