Effect dietary energy levels and feeding rates on growth and body composition of fingerling rainbow trout (Oncorhynchus mykiss)
Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99±0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% rati...

متن کاملEffect of Rearing at Different Densities and Dietary Supplementation with Vitamin E on Growth Indices, Survival and Carcass Composition in Fingerling Rainbow Trout (Oncorhynchus mykiss)
This study was conducted to investigate the effect of rearing at differing densities and dietary supplementation with vitamin E on growth indices, survival and carcass composition in fingerling rainbow trout in a 6-week trial. Rainbow trout juveniles with initial body weight of 9.6 ± 0. 69 g at two densities of 50 and 100 pieces per 50 liter were fed two diets with the same protein and fat cont...
متن کاملSalicylic acid in reducing effect of salinity on some growth parameters of Black cumin (Nigella sativa)
Black cumin (Nigella sativa) is an annual flowering plant in the family Ranunculaceae that beside medicinal value was used as food and cosmetics products. Salicylic acid is a growth regulator with phenolic nature has main role in regulation of many physiological processes and resistance to environmental stress. In order to study effect of salt stress and salicylic acid on some growth parameters...
متن کاملEffects of rearing density on physicochemical properties of water, growth parameters, survival, and body composition of Caspian kutum (Rutilus frisii)
Proper storage density affects the growth and rearing of fish. This experiment was carried out to investigate the effects of rearing densities on the growth and carcass composition of Caspian kutum (Rutilus frisii) fry and physicochemical factors of farming water. Fish were examined in five rearing densities (5, 10, 15, 20, and 25 fish/60 L of water) with three replications, and fed based on 8%...
