PENAMBAHAN SPIRULINA (Arthrospira platensis) PADA PAKAN TERHADAP PERTUMBUHAN DAN KELANGSUNGAN HIDUP IKAN GABUS (Channa striata)
feed efficiency of snakeheads. This research was conducted at the Basic Fisheries Laboratory and Laboratory Microbiology and Fisheries Products Tehcnology, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University in January-March 2024. This research design used a completely randomized design of four treatments and three replications. The treatment given was the addition of spirulina flour to commercial pellets with different percentages, including 0% (P0), 0.5% (P1), 1.0% (P2) and 1.5% (P3). The research results showed that the best percentage of adding spirulina flour to commercial pellets for snakehead was in P1 (0.5%) which resulted in an absolute growth in weight and length at 2.13 g and 1.23 cm, feed efficiency at 50.76% and survival rate at 96.67%. Water quality data includes temperature ranging from 27.4-29.5°C, pH 6.5-7.1, dissolved oxygen 3.5-4.1 mg L-1 and ammonia 0.024- 0.096 mg L-1 .
