Abstract

Ikan lele mulai dibudidayakan oleh UMKM Sujafish Farm Kecamatan Cikole, Kota Sukabumi pada awal tahun 2023. Lahan budidaya perkotaan yang semakin sempit, biaya pakan semakin mahal, dan ketersediaan air yang terbatas menjadi kendala pengembangan budidaya ikan air tawar di Kota Sukabumi. Salah satu solusi untuk menyiasati hal tersebut adalah pengembangan teknologi Recirculating Aquaculture System (RAS). RAS adalah teknologi budidaya dimana air dapat digunakan kembali setelah difilter secara mekanis dan biologis. Wadah pemeliharaan menggunakan bak bulat berdiameter 2 m dan diisi air dengan ketinggian 0,8 m berjumlah 6 bak. Volume air dalam setiap bak yaitu 2.152 L air. Benih yang digunakan berukuran 8–10 cm dengan kepadatan per bak 318 ekor/m2. Parameter pengamatan yang dilihat adalah suhu, pH, DO, amoniak, nitrit, nitrat, dan pertumbuhan ikan. Aplikasi RAS membuktikan dapat menjaga kualitas air suhu, pH, DO, dan amoniak. Nilai pertumbuhan dan kelangsungan hidup sistem RAS lebih tinggi dibandingkan sistem sirkulasi, sehingga teknologi RAS dapat menjadi alternatif solusi teknologi budidaya ramah lingkungan di daerah perkotaan.

Abstract

The nilem (Osteochilus vittatus) is an endemic freshwater species native to Indonesia and is valued both for its therapeutic properties and its potential for processing into value-added products such as baby fish chips. However, its relatively low growth rate remains a major constraint in aquaculture development. The effect of overlapping feeding on the growth performance and survival of nilem larvae was evaluated. Spawning was conducted over three periods using hormone-induced broodstock prior to larval rearing, and fertilized eggs were incubated under controlled conditions. Larval rearing was carried out at the Freshwater Fish Germplasm Research Installation using two feeding treatments with two replicates: a non-overlapping feeding regime, in which Infusoria was administered from day 4 to 7 followed by artificial feed, and an overlapping regime, in which Infusoria was provided from day 3 to 10 alongside artificial feed from day 8 to 10 before transfer to outdoor concrete tanks. Higher absolute weight gain (0.022 ± 0.001 g), absolute length gain (0.78 ± 0.03 cm), specific growth rate (3.30 ± 0.135%), and survival rate (90.0 ± 0.89%) were recorded under overlapping feeding compared to the non-overlapping treatment (0.018 ± 0.001 g; 0.67 ± 0.01 cm; 2.76 ± 0.111%; and 86.1 ± 0.62%, respectively). Significant differences (p<0.05) were observed in absolute length gain and survival, while absolute weight gain and specific growth rate were not significantly affected. Overlapping feeding was demonstrated to improve larval performance and can be recommended as a feeding strategy to enhance hatchery productivity in nilem aquaculture.
