the investigation of protein and lipid in muscle of iranian oncorhynchus mykiss and franciscan oncorhynchus mykiss using their larva that produce in iran & franciscan

the object of this study was detecting protein and lipid contents on two types on iranian oncorhynchus mykiss & franciscan oncorhynchus mykiss for detect better samples on quality. in this research two methods were used for determining lipids (suxeleh) and proteins (kajheldal). results have revealed the lipid contents in iranian samples were 4.88 , 5.18 and 5.96 and in franciscan samples were 4.33, 5.05 and 6.21 respectivcy. there were not significant difference in lipid contents (p<0/05). in this study range of lipid contents were the same in all fishes. fishes had 5-10./. middle range of lipid content. and protein contents in iranian samples were 19.26,18.51,17.52 respectively and for franciscan samples in three treatmens 21.16,21.05,20.67 respectively. protein content had significantly difference in these sampels (iranian&franciscan;). the survey have in franciscan oncorhynchus mykiss the amount of protein is more iranian oncorhynchus mykiss, so franciscan oncorhynchus mykiss is better than iranian oncorhynchus mykiss.
