This paper studies the radionuclide (137Cs, 226Ra, 232Th, 40K) activity concentrations and gross radioactivities in waters and sediments of Lake Van, which is the third largest closed lake (with no natural or artificial outlet) within the Earth. The physico-chemical parameters were measured and evaluated in the lake waters. The mean gross α activit...

Understanding the relative contributions of different spawning habitats to adult fish populations is central to effective fisheries management and species conservation. The Tarek (Alburnus tarichi) is an adfluvial cyprinid that is endemic to the alkaline-saline waters of Lake Van, Turkey. Tarek are culturally and economically important to the regio...

Heavy metals may cause serious problems for human health in contaminated water resources. Therefore, this study aimed to evaluate the metal contamination levels in Sihke Pond surface water and assess the possible human health risk for children and adults through ingestion of the surface water. The concentrations of thirteen heavy metals (aluminum,...

In this study, the water pollution caused by the bilge waters of the ships operating in Lake Van was investigated. While the water temperature (WT), pH, dissolved oxygen (DO), oxygen saturation (OS), electrical conductivity (EC) and salinity parameters were measured in ten different stations where the ships are sheltered, chemical oxygen demand (CO...

Increasing pollution of plastics smaller than 5 mm (microplastics [MPs]) in seas and oceans as well as in inland waters around the world has recently been a significant threat to water resources. In this study, MP pollution levels were investigated using a 335 µm mesh manta trawl in November 2019 in Van Bay. Water samples were collected from 15 sta...

Purpose Microplastic pollution is a major problem that threatens freshwater mussels as well as marine bivalves, since these filter-feeding organisms are directly exposed to microplastics in the water column. There is no study on the microplastic contamination of Unio stevenianus as a bioindicator organism. This aim of the study is to determine the...

Microplastic pollution of inland environments has been receiving increased publicity over the last few years. For the first time, this study reports on the presence of microplastics (0.1 mm to <5 mm) in the gastrointestinal tracts of Alburnus tarichi in Lake Van from January to April 2020. In total, 101 fishes were obtained from Citoren, Edremit, G...

Morali, Akkopru, and Kurbas Rivers are rivers flowing into Lake Van passing through the highly populated Van City, Turkey. They carry domestic and industrial wastewater to Lake Van. For assessment of the environmental load from these rivers to the lake, a sampling investigation from October 2019 to September 2020 was carried out. Chemical oxygen de...

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 c...

Bu balık türlerinin ekolojik özelliklerinin bilinmesi, türün havza...

In this study, physical, chemical and microbio-logical parameters were analyzed in water samples in order to determine the effects of sand pits and sand extraction in Karasu Stream. The water quality data were collected monthly between June 2014 and May 2016 from five sampling stations distributed along the stream and 39 parameters were examined su...

In this study, the swimming performance of Tarek (Alburnus tarichi), which is the unique fish species that can survive naturally in Lake Van and performs compulsory reproduction migration to freshwater, has been investigated taking into consideration the effects of various factors. The swimming performances of Tarek individuals were investigated in...

Abstract Nucleobindin-2 (NUCB2) is a 396-amino-acid peptide related to food intake and body weight. It suppresses appetite by acting on the hypothalamus, andits derived peptide, nesfatin-1, was shown to reduce food intake and body weight in rodents. In this study, we examined NUCB2 peptide levels in correlation with body weight, length and gender...
