Abstract

High feed costs (accounting for 60–70% of production costs) and the risks of stress in intensive aquaculture necessitate the use of safe, natural feed additives. Kaik-kaik root (Uncaria cordata) contains bioactive compounds such as alkaloids and flavonoids, which have the potential to enhance fish health and metabolic efficiency. This study aimed to analyze the effectiveness of adding Uncaria cordata root extract as a feed additive on feed utilization efficiency, growth performance, and survival rate of Oreochromis niloticus. The experiment was conducted using a Completely Randomized Design (CRD) with four treatments and three replications, namely P0 (0% as control), P1 (2%), P2 (4%), and P3 (6%) inclusion levels of the extract in the feed. The observed parameters included growth performance (weight gain and specific growth rate/SGR), feed utilization efficiency (feed conversion ratio/FCR and feed efficiency), and survival rate (SR). The results showed that the addition of the extract had a significant effect (P

Abstract

This study aims to evaluate the potential of peat water microalgae Chlorella sp. on the survival and growth of Betok fish (Anabas testudineus) fingerlings. An experimental method was employed using a Completely Randomized Design (CRD) consisting of three dosage treatments (A: 10 mL, B: 20 mL, C: 30 mL) with three replications. Parameters observed included Survival Rate (SR), absolute weight growth, absolute length growth, and Specific Growth Rate (SGR) over a 42-day rearing period. The results indicated that the administration of peat water microalgae had no significant effect ($P > 0.05$) on any of the tested parameters. However, visually, treatment C (30 mL) showed the highest results with a survival rate of 87.0%, absolute weight growth of 0.64 g, absolute length growth of 1.00 cm, and SGR of 1.13%. This suggests that nutrient intake from microalgae at the fingerling stage is predominantly used for maintaining physiological functions and suppressing environmental stress rather than somatic growth. Water quality parameters during the study remained within the optimal range, with temperatures of 26.0–27.5°C, pH 5.42–6.91, and DO 5.4–6.9 mg/L.
