In this study, the reproductive biology of chub population in Hafik Lake was investigated. 242 samples were caught between April and November 2009. The age of S. cephalus samples were found to range between I-VIII in addition, 153 of them were female and 89 were male. Their fork lengths changed between 114-332 mm, and body weights were between 22.5 and 550.3 g. Male specimens were dete...

nature has always proven that it is able to overcome its problems. however, humanmanipulation has led to environmental degradations. the dryness of a thousand-year urmia lake(a brine water lake in iran) is an example of environmental degradation that happened due tosuccessive droughts and construction of dams on the basin of this lake. this study examinesmethods for the revival of urmia lake by...

According to the water resources and climate change and challenges of Urmia Lake basin, which is the discharge and final destination of North West Rivers, a model was presented. Due to climate change and water resources in river basin such as rainfall, climate change in basin that has direct impact on evaporation over water catchment areas and lake water, this model can be provided. In addition...
