Abstract

The production of silver pompano (Trachinotus blochii) in Indonesia has declined sharply, highlighting persistent issues in its nursery stage, particularly the inability to promote rapid growth and high survival rates when water quality fluctuates. This research assessed intensive nursery techniques implemented at Balai Perikanan Budidaya Laut  (BPBL) in Batam by systematically testing different stocking densities, feeding schedules, and key water-quality metrics. Over a twenty-one-day culture cycle, observers collected data daily and interpreted it using descriptive statistics. Fish length rose from an initial mean of 2.50 cm to 3.73 cm, and mean weight climbed from 0.50 g to 1.30 g, yielding an average specific growth rate of 2.5% per day, a survival rate of 83.7%, and a feed-conversion ratio of 2.1. During the trial, temperature (27.6 °C), pH (7.81), dissolved oxygen (5.7 mg/L), and salinity (30 ppt) consistently fell within national SNI 7901-2013 standards. Most deaths occurred during grading rather than through cannibalism, indicating that handling stress, rather than predatory behavior, was the primary cause of loss. Collectively, these results establish a reference point for nursery management of T. blochii and furnish Indonesian aquaculture planners with data needed to boost fish-seed output while strengthening coastal community livelihoods

Abstract

Barramundi (Lates calcarifer) is a high-value aquaculture species whose productivity strongly depends on the quality of broodstock management. In many government-operated hatcheries in Indonesia, feeding practices rely heavily on locally available trash fish without standardized supplementation, potentially affecting broodstock performance and water quality. This study aimed to document and evaluate feeding management practices for barramundi broodstock at the Teluk Buo Hatchery, West Sumatra, Indonesia. A descriptive case study was conducted over a one-month period through direct observation of feeding schedules, broodstock biometric data, and water quality monitoring. Broodstock were fed trash fish and squid at 3% biomass twice daily, supplemented with vitamins C, B-complex, and E on a scheduled basis. The broodstock ranged from 1.5–1.8 kg (males) and 5.7–6.5 kg (females), meeting recommended criteria for reproductive readiness. Water quality remained within optimal ranges (temperature 30.2–31.8 °C, salinity 30–33 ppt, pH 7–8, dissolved oxygen 5.5–6.3 mg/L), in compliance with national standards. These results indicate that structured feeding management contributes to broodstock health, gonadal maturation, and environmental stability. The findings provide a practical, replicable model for coastal hatcheries operating under resource-limited conditions and highlight the need for future studies addressing reproductive performance, economic feasibility, and sustainable feed alternatives.

Abstract

To maintain growth and survival, Asian redtail catfish postlarvae require silkworms as live food. However, due to their extreme sensitivity to natural conditions, silkworms will be exceedingly scarce during the rainy season. This study aimed to evaluate fermented commercial feed enriched with curcuminas replacement of silkworms for the growth and survival of redtail catfish postlarvae. This study employed a complete design experiment consisting of six treatments: P1 (non-fermented commercial feed), P2 (no curcumin-enriched fermented commercial feed), P3 (curcumin-enriched fermented commercial feed at 0.35 g/kg), P4 (curcumin-enriched fermented commercial feed at 0.70 g/kg), P5 (curcumin-enriched fermented commercial feed at 1.05 g/kg), and P6 (silkworms). Each treatment was replicated four times. The Asian red tail catfish postlarvae, measuring 0.63 ± 0.05 mm in length, were cultivated at a density of 5 fish/L. Fish were raised for a period of thirty days. Growth in total weight, total length, specific weight rate, specific length rate, and survival rate of postlarvae were the parameters measured. The growth evaluation results indicate that substituting silkworm feed with fermented feed supplemented with curcumin at a concentration of 1.05 g/kg resulted in growth of 6.66% (length) and 14.29% (weight) lower than the silkworm treatment (P<0.01). Despite this decline, it represents the most effective outcome in this study, highlighting the potential of fermented feed where enrichment with curcumin as an alternative to silkworms for Asian redtail catfish larvae nutrition. In conclusion, curcumin-enriched fermented feed can promote the growth of Asian redtail catfish postlarvae. Keywords: curcumin, fermented feed, growth, silkworm   Abstrak Untuk mempertahankan pertumbuhan dan kelangsungan hidup, postlarva ikan baung membutuhkan cacing sutra sebagai makanan hidup. Namun, cacing sutera sangat sensitivitas terhadap kondisi alam, cacing sutra akan sangat langka selama musim penghujan. Untuk mengganti cacing sutra, penelitian ini mengevaluasi pakan alternatif (pakan komersial terfermentasi yang diperkaya dengan kurkumin). Penelitian ini merupakan eksperimen dengan acak lengkap satu faktor yang terdiri dari enam perlakuan: yaitu P1 (Pakan komersial non-fermentasi), P2 (pakan komersial fermentasi yang diperkaya kurkumin), P3 (pakan komersial fermentasi yang diperkaya kurkumin pada 0,35 g/kg), P4 (pakan komersial fermentasi yang diperkaya kurkumin pada 0,70 g/kg), P5 (pakan komersial fermentasi yang diperkaya kurkumin pada 1,05 g/kg), dan F (cacing sutra). Setiap perlakuan diulang empat kali. Postlarva ikan baung, berukuran panjang 0,63 ± 0,05 mm, dibudidayakan pada kepadatan 5 ekor/L. Ikan dipelihara selama tiga puluh hari. Parameter yang diukur dalam penelitian ini adalah pertumbuhan berat total, panjang total, rata-rata pertumbuhan bobot, dan panjang spesifik serta kelulushidupan. Berdasarkan hasil evaluasi pertumbuhan menunjukkan pergantian pakan cacing sutera dengan pakan fermentasi yang diperkaya kurkumin 1,05 g/kg pakan menghasilkan pertumbuhan 6,66 % (panjang) dan 14,29% (berat) lebih rendah dari perlakuan cacing sutra (P<0,01), dan ini melrupakan hasil terbaik dari penelitian ini dalam upaya mencari pengganti pakan alternatif cacing sutera untuk postlarva ikan baung. Sebagai kesimpulan, pakan pasta terfermentasi yang diperkaya kurkumin dapat meningkatkan perkembangan postlarva ikan baung. Kata kunci: cacing sutera, kurkumin, pakan terfermentasi, pertumbuhan
