      Now days, nutritional labeling of fish edible products and calculation of its fillet yield are important needs for fish processing industries. The present study was done to investigate Determination of chemical composition and fillet yield of silver carp (Hypophthalmichthys molitrix) for grading and nutritional labeling of its products by regression equations. For this purpose 50 specimens silver carp were applied in marketing size and their fillet yield, moisture, lipid, protein, ash and energy content were measured. Then, the relationships between these parameters with total length were considered and type of relationship and equation of them were determined. According to obtained results, the relationship between moisture content with fish total length was in inverse linear regression form (p<0.05), while the relationships between lipid, protein and energy content of fillet with fish total length was in positive linear regression form (p<0.05). In generally these equations was in Y= bX± a form. The relationship between protein content and fish total length was significant but weak. According to obtained results there is not relationship between fillet ash content and fish size. Regarding these results and determining their equations, fish length can be used for fish sorting by sorting machine and then economic calculations and determination of moisture, lipid, protein and energy content by obtained equations were done for each group and finally, nutritional labeling and deciding for processing were done for each group.
