Abstract: Current demand for aquatic animal consumption is increasing daily. This occurs alongside persistent problems in the fisheries sector, including labor issues and declining wild fish stocks, compounded by environmental degradation that is causing natural aquatic resources to dwindle daily. To compensate for the reduced output of aquatic animals from natural sources, farmers have been encouraged to shift towards aquaculture. Selecting the appropriate fish species for farming is a key factor for farmers' investment decisions. Climbing perch (Anabas testudineus), a fish that is both resistant to changing environmental conditions and economically viable, was chosen for this study. The research investigated the digestibility of residues from biogas sludge as a replacement for rice bran in feed to determine the optimal level for growth and yield and to study cost reduction. The study on the optimum pH for the functional activity of two digestive enzymes found that the pH level significantly affected the activity of amylase and trypsin enzymes extracted from the gastrointestinal (digestive system) of the climbing perch. The amylase enzyme activity showed the highest average at pHÿ10, while the trypsin enzyme activity showed the highest average at pHÿ6. The information obtained from this study on pH can therefore be used to further investigate the optimal temperature for both enzymes. In the cost study, Treatment 1 (the control, 0% biogas sludge), which contained no biogas residue, showed the highest production cost, which decreased, respectively, when compared to commercial feed and feed produced with biogas sludge.
