PENAMBAHAN LISIN PADA PAKAN KOMERSIAL TERHADAP PERTUMBUHAN DAN EFISIENSI PAKAN IKAN BETOK (Anabas testudineus)

The main constraint in climbing perch (Anabas testudineus) culture is its relatively slow growth rate, which can affect the productivity and efficiency of aquaculture cultivation. The primary factors contributing to fish growth include feed quality, nutrient content, and the balance of essential amino acids. One effort to improve feed efficiency is through the supplementation of essential amino acids that may act as limiting factors, such as lysine, which plays an important role in protein synthesis and energy metabolism. This study aimed to determine the optimal lysine dosage for improving the growth performance and feed efficiency of climbing perch. The study employed an experimental method using a completely randomized design (CRD) consisting of four treatments: P0 (without lysine supplementation), P1 (lysine supplementation at 1.5% kg⁻¹ feed), P2 (lysine supplementation at 2.0% kg⁻¹ feed), and P3 (lysine supplementation at 2.5% kg⁻¹ feed), with three replications. The parameters were observed included absolute length and weight gain, specific growth rate, protein efficiency ratio, feed efficiency, survival rate, and water quality. The results showed that the best lysine supplementation dose in commercial feed for climbing perch was 2.5% kg⁻¹ feed (P3), resulting in an absolute length gain of 1.04±0.03 cm, an absolute weight gain of 1.04±0.03 g, a specific growth rate of 1.21±0.13% day-1, a protein efficiency ratio of 1.16±0.01, feed efficiency of 44.49±0.45%, and a survival rate of 95.44–100.00%. Water quality parameters were within suitable ranges, including temperature of 25.8–27.2°C, pH of 6.2–7.1, dissolved oxygen of 5.5–6.5 mg L⁻¹, and ammonia concentration of 0.030–0.043 mg L⁻¹. The observed range remained within the optimal limits for climbing perch cultivation. The observed range remained within the optimal limits for climbing perch cultivation. This study demonstrated that lysine supplementation in commercial feed at a dose of 2.5% kg⁻¹ feed was the best treatment for improving the growth performance and feed efficiency of climbing perch.
