Atlantic salmon Salmo salar L. and brown trout trutta fario are species of high socio-economic ecological value. Declining populations make them target fisheries management. This paper reviews the direct effects deficient longitudinal connectivity, changes in discharge, water temperatures, oxygen depletion, chemistry increasing loads fine sediment on critical life stages spawning, egg incubatio...
In the protected area of the Cévennes National Park (Southern France), 114 wild brown trout (Salmo trutta fario) were captured at six locations affected to different extents by historical mining and metallurgy dating from the Iron Age to Modern Times. Cadmium and lead in trout livers and muscles reflect high sediment contamination, although an age-related effect was also detected for hepatic me...
Managing brown trout (Salmo trutta fario) populations is of high concerns for many stakeholders (e.g. angling associations or hydropower companies). However, building trout life cycle models remains challenging. Here, we describe a general hierarchical Bayesian model of brown trout population dynamics that combines global (e.g. an average value of age-class annual survival) and local parameters...
قزلآلای خال قرمز جمعیتی آسیبپذیر از ماهی آزاد دریای خزر بوده ولی در اغلب آبهای شیرین حوزه ایرانی دریای خزر انتشار دارد و در رودخانه شفارود نیز، این ماهی دارای فراوانی مناسبی در مناطق بالادست است. این بررسی با هدف آشنایی از خصوصیات زیست شناختی تغذیه قزل آلای خال قرمز و از زمستان 1388 تا پاییز 1389 انجام و از دستگاه الکتروشوکر و تور پرتابی جهت صید ماهیان استفاده شد. ماهیان مورد بررسی دارای اوزا...
Nucleospora salmonis (Hedrick, Groff et Baxa, 1991), an intranuclear microsporidian parasite of marine and freshwater fish, causes diseases mainly in salmonid species. Losses have been reported in stocks of salmonid fish reared in the region of Auvergne (France). The cause of chronic mortalities in the local host species raised in aquaculture and destined for supplementation of the river system...
The present study was designed to enlist the physiochemical and functional properties of very low-density lipoprotein receptor Salmo trutta fario (brown trout), provide information about its three-dimensional structure interaction with partner molecules using standard bioinformatic tools. VLDL is a large flexible protein molecular weight around 95.9 kDa, relatively unstable, hydrophobic primary...
