To determine relative protein digestibility (RPD) of different feed ingredients for walking catfish (Clarias batrachus) locally known as Magur, in vitro technique was conducted. Gut enzyme extracted from the experimental species was used to assay RPD through pH drop method. Higher relative protein digestibility was obtained from Meat & Bone meal (94.92 ± 0.00%), followed by Fish meal (86.44 ± 1.69%), Soybean meal (74.01 ± 2.59%) and Mustard oil cake (69.49 ± 0.00%) and the lowest was observed from Rice polishing (33.90 ± 0.00%).From the result it is assumed that Meat Bone meal, Fish meal and Soybean meal would be the alternative protein sources of Fish meal for cost effective diet preparation of C. batrachus.
