<![CDATA[This study aimed to evaluate the effect of incorporating lamtoro leaf flour (Leucaena leucocephala) into formulated feed on the growth rate and survival of pearl catfish (Clarias gariepinus), as well as to determine its optimal inclusion level. The experiment was conducted using a Completely Randomized Design (CRD) with four treatments and three replications: P0 (control/no lamtoro leaf flour), P1 (10% LLF), P2 (20% LLF), and P3 (30% LLF). Descriptive results indicated that treatment P1 (10% LLF) yielded the best performance, with a specific growth rate (SGR) of 1.82±1.14% per day, absolute length gain of 3.9±2.11 cm, absolute weight gain of 22.7±18.64 grams, and a positive allometric growth pattern. The lowest feed conversion ratio (FCR) was recorded at 5.42. Survival rates (SR) were high across all treatments, with the highest value of 100% observed in P1 and P3. However, statistical analysis showed no significant differences among treatments for all observed parameters (p>0.05), thus the null hypothesis was accepted. Water quality during the study remained within optimal ranges as specified by Indonesian National Standard (SNI) No. 3 of 2014.]]>
