Completely Randomize Design (CRD) with 4 treatments and 4 replications. The treatments were 4 different levels of light intensity, T1: 900 – 1,100, T2: 1,900 – 2,100, T3: 3,900 – 4,100 and T4:7,900 – 8,100 Lux. The collected data of the tadpoles were weight, length, survival rate, feed conversion ratio, daily feed intake and specific growth rate. The results indicated that the weight, length, feed conversion ratio, daily feed intake and specific growth rate of tadpoles in all treatments were not significantly different (p&gt;0.05). The survival rates of tadpoles were significantly different (p&lt;0.05).&nbsp; The highest survival rate of 69.33±7.57 % was found in T1:900 – 1,100 Lux and the lowest survival rate of 56.67±1.15 % was found in T4:7,900 – 8,100 Lux.</p> ER -
