A killifish species Aphanius ginaonis occurs in Geno hot spring is one of the unique fish species that could successfully survive and acclimated to the high temperature of hot springs. In this study, we investigated the effects of Geno's cyanobacteria extracts on growth, survival and morphology of gill tissue in Aphanius dispar exposed to normal temperature and long-term thermal stress. For thi...
تجزیه وتحلیل ویژگی های ریختی برای بررسی وضعیت جمعیت ها ی کپوردندان اصفهان (aphanius isfahanensis) در اکوسیستم آبی استان اصفهان مورد بررسی قرار گرفت. بدین منظور، تعداد 227 نمونه از 4 ناحیه مختلف حسن آباد، ورزنه، مالواجرد و زرین شهر نمونه برداری شد. برای تشخیص تنوع ریختی از روش ریخت سنجی هندسی استفاده شد. رابطه طول-وزن یک فاکتور اصلی در مطالعات شیلاتی است و در مطالعه حال حاضر b بدست آمده در کل جم...
Abstract Research on several social fishes has revealed that shoals constituted by familiar individuals behave remarkably differently compared to formed unfamiliar individuals. However, whether these behavioural changes may arise also in composed a mixture of and individuals, situation commonly occur nature, is not clear. Here, we observed the behaviour Mediterranean killifish ( Aphanius fascia...
aphanius ginaonis is exclusive to the geno hot spring, located in the hormozgan province. in this paper some biological aspects of aphanius ginaonis and contents of its digestive tract and its relation with cyanobacteria (blue-green algae) in the geno hot spring was examined. sampling was conducted monthly, samples were fixed in 5% formalin immediately after fishing and transferred to the ichth...
The inlandwater resourses are including;lakes,wetlands,rivers ,springs and qanats. The qanat is the water or channel through which water flows from the depths of the earth to its surface. Over the past two decades, studies have been done on the inlandwater resources by writers of this article and other reseachers. The results of the studies showed that 22 fish species belonging to 5 family com...
در این مطالعه تنوع ژنتیکی جمعیت ماهیان گورخری گنو و معمولی با استفاده از روش PCR-RFLP بررسی گردید. جهت تعیین تنوع ژنتیکی این دو ماهی در حوضه خلیج فارس، تعداد 30 نمونه ماهی گورخری گنو (Aphanius ginaonis) از چشمه آب گرم گنو در استان هرمزگان و 30 نمونه ماهی گورخری معمولی (Aphanius dispar) از چشمه آب گرم میراحمد در استان بوشهر جمع‌‌آوری گردید. جهت هضم آنزیمی محصول PCR به طول 550 جفت‌‌باز در ناحیه...
Rising trend of production and use of nanoparticles can lead to the possibility of their release into aquatic environments. Therefore, knowing toxic effects of these materials on aquatic organisms is of great importance. The objective of this research was to study the acute toxicity of colloidal silver nanoparticles (CAgNPs) through determining the lethal concentrations in the euryhaline teleos...
