The Snow trout, Schizothorax zarudnyi Nikolskii, 1897 belongs to Cyprinidae family, endemic to Hamoun Lake, Sistan, Iran. Female fish mature at 4 years old, a few at 3 years old, and male fish at 3 years old, and live in the rivers and lagoons of Hamoon (stagnant waters) and spawn in the same place. Natural fish populations have declined during the last several years because of environmental de...
Disruption in gonadal development of wild roach living in U.K. rivers receiving large volumes of treated sewage effluent is manifest in a variety of ways, ranging from malformation of the germ cells and/or reproductive ducts to altered gamete production. Intersex fish were also found to have an altered endocrine status and an elevated concentration of plasma vitellogenin. Gonadal growth was inh...
Traces of active pharmaceutical ingredients (APIs) and other chemicals are demonstrated in effluents from sewage treatment plants (STPs) and they may affect quality of surface water and eventually drinking water. Treatment of effluents with granular activated carbon (GAC) or ozone to improve removal of APIs and other contaminants was evaluated at two Swedish STPs, Käppala and Uppsala (88 and 10...
Laboratory tests with marine flatfish were conducted to investigate associations among gene expression, higher biological responses and wastewater effluent exposure. In the present study, male hornyhead turbot (Pleuronichthys verticalis) were exposed to environmentally realistic (0.5%) and higher (5%) concentrations of chemically enhanced advanced-primary (PL) and full-secondary treated (HTP) e...
In this study, we evaluated the effects of treated effluent of Khuzestan Pars Paper Industry (0.5% and 1%) on liver biochemical factors of Alburnus mossulensis during 21 days. There were significantly increased aspartate aminotransferase, lactate dehydrogenase and creatine phosphokinase levels observed in fish after a 21-day exposure to treated effluent. Alanine aminotransferase, alkaline phosp...
In this study has been attempted to evaluate some hematological, serological and immunological indices to determine the baseline for determining the health of SPF brood stock. For this purpose, during three sampling stages, before, simultaneously and after breeding time, the blood samples were collected from brood stock fish at the SPF center in the Cold water fisheries research Center (Tonekab...

The patient, a 77-year-old-man, began peritoneal dialysis (PD) in August 2005. In January 2009, he developed lower abdominal pain and cloudy PD effluent. A diagnosis of peritonitis was made and Escherichia coli was detected in cultures of the PD effluent. An abdominal computed tomography scan showed a fish bone in the duodenal wall. An upper gastrointestinal endoscopy was performed, and a 3-cm ...
The hypothalamic-pituitary-adrenal/interrenal (HPA/I) axis plays a key role in responding to biotic and abiotic challenges in all vertebrates. Recent studies have shown that the apical response of the HPI axis to stressors in three-spined sticklebacks varies in proportion to the concentration of wastewater treatment works (WWTW) effluent to which the fish are exposed. This study was conducted t...
