Abstract :
This study considered the effect of stocking density on ‚immune factors and stress rate in brown trout (Salmo trutta caspius). Scrods have been saved on 3 accumulations 50‚75 and 100 in each cub meter with primary weight mean 7/25±0/4 g.the duration of experience period was 60 days .cortisol hormone rate and immune factors such as immunoglubolin (Igm)‚ complemans (c3‚c4) and total protein and calcium have evaluated.the results indicate that it has an increasing accumulation on safe factors such as immunoglubolin(Igm)‚complemans(c3‚c4)‚total protein‚ blood calcium and the rate of cortisol hormone has not a significant effect (P>0.05). Although the parameters related to stocking density in brown trout (Salmo trutta caspius and have increased dietary change coefficient‚ but this increasing on the range of used stocking density of this study was not stressor for scrod and has not an effect on immune factors of fishes.
