the effect of soybean and egg lecithin on the growth, survival and resistance to anoxia stress in rainbow trout (oncorhynchus mykiss) alevin
نویسندگان
چکیده
this study was conducted to evaluate the effect of different lecithin sources and their levels on growth performance and resistance to anoxia stress of rainbow trout (oncorhynchus mykiss) alevin with initial weight of 120 ± 4.08 g for 40 days. soybean and egg lecithin at 2, 4 and 6 ? levels were added to the diets. seven treatments by three replications were used in this experiment. therefore, 165 alevin were used per each 90 l tank. alevin were fed to visual satiation at six meals per day for 40 days. at the end of experiment, alevins were fed by 2? egg lecithin had significantly higher (p

Effect of nanosilver particles on hatchability of rainbow trout (Oncorhynchus mykiss) egg and survival of the produced larvae
Effect of nanosilver particles was studied on the hatchability of rainbow trout (Oncorhynchus mykiss) egg and survival of the produced larvae at about 12ºC. In the first experiment the water-based nanosilver particles was used at concentrations of 0.5, 1, 2 and 4 mgL-1 for 30 minutes per day starting 24 hour post egg incubation until the hatching time. The mean percentage of hatchability reach...

متن کاملRainbow Trout, Oncorhynchus mykiss
Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...
متن کاملEffects of chitosan on hematological parameters and stress resistance in rainbow trout (Oncorhynchus mykiss)
The aim of our study was to evaluate the effects of chitosan as immune stimulator on some hematological parameters and stress resistance in rainbow trout. Nine hundred rainbow trout (with initial body weight of 25 ± 0.1 g) were obtained from a local farm and acclimated to the laboratory conditions for one week. After that fish were randomly divided into four groups in three replicates. Each gro...
متن کاملThe effects of oxygen supplementation on growth and survival of rainbow trout (Oncorhynchus mykiss) in different stocking densities
In this study, the effects of oxygen supplementation in different stocking densities of rainbow trout (Oncorhynchus mykiss) on the specific growth rates (SGR), feed conversion ratios (FCR) and survival rates were investigated in a commercial-scale culture system. High density cultures were maintained in a total of nine (12 m3) flow-through systems supplemented with O2. Initial stocking rates fo...
