Abstract

Ikan nila merupakan salah satu komoditi perikanan air tawar yang dapat ditingkatkan kualitas produksinya melalui teknik budidaya monoseks jantan. Teknik monosex jantan dapat dilakukan dengan menggunakan hormon sintetik seperti 17α-metiltestosteron yang tidak disarankan dalam upaya peningkatan kualitas produksi pangan karena meninggalkan residu karsinogenik. Berdasarkan hal ini maka penggunaan bahan alami dalam meningkatkan kualitas hasil produksi sangatlah direkomendasikan. Madu merupakan bahan alami yang menggandung chrysin yang dapat digunakan untuk teknik maskulinisasi pada ikan nila. Keefektifan senyawa bahan alam dalam teknik maskulinisasi juga dipengaruhi oleh faktor lingkungan seperti suhu. Penelitian ini bertujuan untuk mengetahui pengaruh suhu terhadap jumlah kelamin jantan yang dihasilkan dan mengetahui suhu terbaik dalam teknik maskulinisasi menggunakan larutan madu. Penelitian ini dilakukan menggunakan 4 perlakuan suhu dengan menggunakan konsentrasi madu (15 mL/L). Larva yang digunakan adalah larva umur 7 hari setelah menetas yang diperoleh melalui pemijahan semi buatan dengan induksi hormon. Untuk mengetahui jumlah kelamin jantan, analisa histologis dengan pewarnaan asetokarin dilakukan untuk mengamati gonad benih yang dihasilkan. Hasil yang diperoleh menyatakan bahwa perendaman larva ikan nila dalam larutan madu pada suhu 32°C menghasilkan jumlah kelamin jantan sebesar 86,7%. Berdasarkan hasil ini dapat ditarik kesimpulan bahwa perlakuan suhu yang digunakan dalam teknik maskulinisasi dengan menggunakan madu berpengaruh terhadap rasio kelamin jantan yang dihasilkan dan kombinasi suhu 32°C pada teknik maskulinisasi dengan menggunakan madu memberikan nilai tertinggi terhadap kelamin jantan yang dihasilkan.

Abstract

Giant gourami (Osphronemus gouramy) is one of Indonesia's most valuable freshwater fish species; however, its aquaculture development is constrained by slow growth and low survival rates. Improving water quality through the use of aquatic plants such as Lemna sp. and the application of eco-enzymes is essential. The development of Lemna sp. depends on nutrient availability, especially nitrogen (N), phosphate (P), and potassium (K), which can be enhanced by adding an eco-enzyme. This study aimed to evaluate the effect of different eco-enzyme concentrations on Lemna sp. biomass production, specific growth rate, and water quality parameters in giant gourami culture systems. The research was conducted using an experimental method with a Completely Randomized Design (CRD) consisting of five treatments and three replications: P0 (0 ml/L), P1 (1.5 ml/L), P2 (2.5 ml/L), P3 (3.5 ml/L), and P4 (4.5 ml/L) of eco-enzyme concentration. The results showed that eco-enzyme administration significantly influenced Lemna sp. biomass. The best results were observed in treatment P4 (4.5 ml/L), which produced the highest Lemna sp. biomass (132.87 g) and specific growth rate (4.47%). Optimal water quality was recorded in treatment P4, with temperature ranging from 26.1–29.8°C, pH 5.5–8.38, dissolved oxygen 3.10–6.42 mg/L, phosphate 0.3097–0.3872 mg/L, nitrate 0.5517–10.2414 mg/L, and CO₂ 17–40 mg/L. These findings demonstrate that eco-enzyme application at 4.5 mL/L effectively enhances Lemna sp. productivity as a natural biofilter while simultaneously improving giant gourami growth performance and survival

Abstract

Cosmos caudatus is a herb that benefits overall health. This study aimed to determine the effect of C. caudatus leaf supplementation in feed on blood glucose levels in catfish (Pangasianodon hypophthalmus) challenged with Aeromonas hydrophila. This study was conducted from March to August 2024 at the Marine Microbiology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The method used was an experimental design employing a completely randomized design (CRD) with four treatments and three replications: negative control (NC, no supplementation, no infection), positive control (PC, no supplementation, with A. hydrophila bacterial infection), supplementation with C. caudatus at doses of 10 g/kg (T1), 15 g/kg (T2), and 20 g/kg (T3) of feed, all tested against A. hydrophila. The fish fry used weighed 5.00 ± 1.00 g and were reared for 75 days in 100-L tanks integrated with an aquaponics system. The fish were fed the experimental feed for 60 days before challenge with A. hydrophila bacteria (10⁸ CFU/mL, intramuscular injection) and continued for 14 days after challenge. Blood glucose levels were measured at the beginning (day 1), day 30, pre-challenge (day 60), and post-challenge (day 75). The results showed that adding basil leaves to the feed affected blood glucose (P<0.05). The addition of C. Caudatus leaves maintained glucose homeostasis within the range of 68.33±10.59-79.67±7.77 mg/dL. These findings indicate that C. Caudatus supplementation effectively prevents hyperglycemia caused by A. hydrohila infection in striped catfish and suggest its potential as a natural immunostimulant and metabolic modulator in aquaculture

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.
