The feeding trial was conducted for 56 days (eight weeks) based on five dietary treatments at varying proportions of FM and FSP (T1: 50% FSP, 30% FM; T2: 60% FSP, 20% FM; T3: 70% FSP, 10% FM; T4: 75% FSP, 5% FM; T5: 80% FSP, 0% FM), with the commercial pellet (Starfeed) serving as control. Chemical analyses showed that both T1 and T3 had the highest protein content (18.1%). Meanwhile, the control group showed the best performance in terms of specific growth rate (SGR) and feed conversion ratio (FCR), and these values were significantly different (p < 0.05) from the five dietary treatments. In contrast, the survival rate of T1 group (82.5%) was comparable to the control group (85.0%). All the dietary treatments showed histological changes in fish liver: < 25% changes for T1, T2, and T3, whereas < 50% changes in T4 and T5. However, the control group did not exhibit any histological changes in the liver. Therefore, FSP is recommended as a dietary supplement for red hybrid tilapia. |
