| The sustainability and cost-effectiveness of aquafeeds are crucial research focus in the aquaculture industry. This study investigates Chaya leaf meal (CLM; Cnidoscolus aconitifolius) as an alternative to soybean meal (SBM) in climbing perch (Anabas testudineus) diet. Over a three-month feeding trial, three dietary modifications were tested, incorporating 0% (CLM 0, control group), 20% (CLM 20), and 40% (CLM 40) Chaya leaf meal. The growth performance parameters indicated no significant differences between the dietary groups (p>0.05). However, 20% CLM diet led to significantly improved survival rates (p<0.05). Detailed analysis of organosomatic indices, body composition, fillet proximate composition, hematological, and blood chemical indices demonstrated overall consistency across experimental diets (p>0.05), except for a notable variance in the crude lipid content. Likewise, digestive enzymes activity remained stable across the dietary groups. From an economic standpoint, 20% CLM diet exhibited a competitive profit index compared to the control, significantly outperforming 40% CLM diet (p<0.05). These findings support the viability of 20% CLM as a partial substitute for soybean meal in climbing perch diets, providing environmental and economic advantages. Nevertheless, additional research is essential to determine the optimal CLM inclusion level and understand its long-term impact on fish health and productivity. |
