This study was conducted to illustrate the effect of dietary gelatinized starch (GS)on the growth performance, enzyme activities and expression of MyoD and Myf5 inmagur,Clarias batrachusfingerlings. Four iso‐nitrogenous (37%) and iso‐lipidic (6%)diets containing 15% (D‐1), 25% (D‐2), 35% (D‐3) or 45% (D‐4) GS were fed to 240fingerlings (2.5 ± 0.5 g) in triplicates groups for 8 weeks. The maximum weight gain%, specific growth rate, protein efficiency ratio, lower FCR and higher mRNAexpression of MyoD or Myf5 were found in the D‐3 group fed with 35% GS. Higherhepatosomatic index, viscerosomatic index, body lipid and lower moisture contentwere found in the D‐4 group. Aspartate transaminase and alanine transaminaseactivities were found to be higher in the D‐1 group. Amylase, glucose‐6‐phosphatedehydrogenase and blood glucose were higher in the D‐4 group. Superoxide dismu-tase, catalase and hexokinase activities remain unaffected by the dietary GS levels.Hence, the overall results indicate that 35% GS can improve growth performanceand upregulate myogenic regulatory factors, but 45% GS level will favor lipogenesisand compromise growth. Furthermore, Myf5 gene showed more immediate responsethan the MyoD to the dietary carbohydrate in magur.
