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 کاملEffects of various feeding and starvation strategies on growth, hematological and biochemical parameters, and body composition of Caspian brown trout (Salmo caspius Kessler 1877) parr
This study was carried out to investigate the effects of starvation and feeding regimes on growth performance, haematological and biochemical parameters of blood and body composition of Caspian brown trout parr. For this purpose, 900 fish (average weight: 12.5±1 g) were stocked in 300-l tanks (18 tanks at a stocking rate of 50 fish in each tank) using an open system. Six experimental groups com...
