Feeding behavior of brown trout, Salmo trutta fario, during spawning season in four rivers of Lar National Park, Iran
Brown trout, Salmo trutta fario, has a wide range of distribution in the north of Iran and in Karaj, Lighvanchai and Karun Rivers, but there is no report about its feeding behavior in some water resources including the Lar Natural Park. In order to study feeding behavior of this fish during spawning season, a survey was carried out in the rivers of Elarm, Aab-Sefid, Kamardasht and Delichayi in ...
متن کاملDetermination of organochlorine pesticide residues in the raw milk taken from milk collection centers in Urmia in 2020
Background and Objective: Milk is one of the most important components of human food. In recent decades, the continued use of pesticides has led to contamination of soil, water, air and milk and caused public concern in the community. Long-term exposure to pesticide residuals in the food chain can be harmful. Therefore, there is a need to control environmental conditions in order to improve its...

متن کاملEffects of Humic Acid on Liver and Kidney Toxicity Induced by Cadmium in Brown Trout (Salmo trutta fario, L)
This study was conducted to determine the histopathological and biochemical effects of humic acid on cadmium stress in liver and kidney tissues of Salmo trutta fario, L. The fish were treated in four groups as follows and were exposed to chemicals for 7 days: control (C), cadmium (2 ppm) (Cd), humic acid (5 ppm) (HA) and humic acid + cadmium (Cd + HA). At the end of the experimental period, liv...
متن کاملPeriphyton density influences organochlorine accumulation in rivers
To investigate the influence of eutrophication on organochlorine dynamics in lotic systems, we related polychlorinated biphenyl (PCB) concentrations in brown trout (Salmo trutta) to the periphyton density and total phosphorus concentrations (Tot-P) in 10 Swedish rivers. Tot-P concentrations in the water ranged from 37 6 4 to 156 6 51 mg L21. Periphyton density in the rivers during the experimen...
