Abstract

Eel aquaculture remains dependent on wild-caught glass eels, whose supply fluctuates seasonally and peaks during the rainy season. Improving nursery efficiency through optimized stocking density is therefore essential. This study evaluated the effects of three stocking densities (1, 2, and 3 g L-¹) on the production performance and financial feasibility of glass eel (Anguilla spp.) nursery operations in recirculating aquaculture systems (RAS). Stocking density significantly affected survival, biomass yield, and profitability (p < 0.05). The highest density (3 g L-¹) resulted in the lowest survival rate (35.69 ± 3.70%), which was significantly lower than both 1 g L-1 and 2 g L-¹, yet produced the greatest biomass (11.42 ± 0.57 g L-¹). Financial analysis showed that all treatments were viable, with 3 g L-¹ yielding the highest profit (IDR 378,035,622 ± 45,089,672). Despite reduced survival, profitability remained relatively stable across treatments, indicating that biomass gain compensated for mortality-related losses. These findings demonstrate that a stocking density of 3 g L-1 provides the most advantageous balance between production output and economic return for glass eel nursery operations in RAS.

Abstract

This study aims to evaluate the effect of stocking density variation on the survival rate of Asian Redtail catfish juveniles (Mystus nemurus) in a closed wet transportation system for 12 hours and post-transportation maintenance for 4 days. The method used a completely randomized design with three density treatments: 83, 167, and 250 fish per liter, each replicated three times. The results showed that a stocking density of 167 fish per liter provided the best survival rate, reaching 100% at the end of transportation and 95,45% after post-transportation maintenance. At the highest density of 250 fish per liter, a significant decline in survival to 64,39% was observed, accompanied by decreased water quality, lowered dissolved oxygen levels, increased ammonia concentration, and physiological stress symptoms in the juvenile. The decline in water quality and accumulation of metabolic waste at high densities contributed to increased stress and mortality. Besides the biological aspects, the business analysis indicated that a stocking density of 167 fish per liter was optimal in terms of economic efficiency, generating a net profit of IDR 21.467 and an R/C ratio of 1,09, making this scenario commercially viable. This study offers valuable recommendations for the sustainable management of Asian Redtail catfish juvenile transportation, promoting increased production and profitability in aquaculture.

Abstract

The increase in Nile tilapia (Oreochromis niloticus) production reflects a rise in fish consumption among the community. The provision of sufficient fry for ongrowing must accompany such a production boost. One way to achieve this is through intensification by increasing the stocking density of tilapia larvae during the nursery phase. This study aimed to analyze production performance and the economics of tilapia larva nursery in a recirculation system under different stocking densities. The experiment was carried out over 42 days using a completely randomized design with stocking density treatments of 5, 10, and 15 larvae per liter, each with five replicates. Differences in stocking density had a significant effect on absolute length growth rate (AGRL), specific length growth rate (SGRL), feed conversion ratio (FCR), and productivity. The 15 fish/L treatment yielded higher LPMP, SGR, and productivity than the other treatments, while showing the lowest FCR. It was concluded that the best production performance and economic return in a recirculating tilapia larva nursery system were achieved at 15 fish/L, delivering an annual productivity of 106,112 fish/m³, a revenue-to-cost ratio of 1.54, and a payback period of 0.65 years.

Peningkatan produksi perlu diikuti dengan penyediaan benih yang mencukupi untuk pembesaran. Upaya yang dapat dilakukan adalah dengan intensifikasi melalui peningkatan padat tebar larva nila pada tahap pendederan. Tujuan penelitian ini adalah menganalisis kinerja produksi dan usaha pendederan larva ikan nila pada sistem resirkulasi dengan padat tebar berbeda. Penelitian dilakukan selama 42 hari menggunakan rancangan acak lengkap dengan perlakuan padat tebar larva ikan nila, yaitu 5, 10, dan 15 ekor/L dengan lima ulangan. Perlakuan perbedaan padat tebar berpengaruh nyata terhadap laju pertumbuhan mutlak panjang (LPMP), laju pertumbuhan spesifik panjang (LPSP), rasio konversi pakan (RKP), dan produktivitas. Perlakuan padat tebar 15 ekor/L menghasilkan LPMP, LPSP, dan produktivitas yang lebih tinggi daripada perlakuan lain, sedangkan nilai RKP menunjukkan nilai terendah. Penelitian menghasilkan kesimpulan bahwa kinerja produksi dan usaha terbaik pada pendederan ikan nila bersistem resirkulasi dihasilkan pada padat tebar 15 ekor/L dengan memberikan produktivitas sebesar 106.112 ekor/m3 per tahun, revenue/cost ratio senilai 1.54, dan payback period yaitu 0.65 tahun.

Abstract

Prosedur cara pembenihan ikan yang baik (CPIB) merupakan standar nasional untuk menjamin biosekuriti, ketertelusuran produk, dan keberlanjutan kegiatan pembenihan dalam menghasilkan benih ikan berkualitas tinggi. Penerapan prosedur ini tidak hanya menentukan aspek teknis produksi, tetapi juga memberikan konsekuensi finansial bagi pelaku usaha akuakultur. Penelitian ini bertujuan mengkaji kinerja produksi dan kinerja finansial usaha pembenihan ikan nila (Oreochromis niloticus) yang menerapkan CPIB di Desa Kutasirna, Kecamatan Cisaat, Kabupaten Sukabumi, Jawa Barat, Indonesia. Metode non-eksperimental diterapkan untuk membandingkan kinerja usaha sebelum dan sesudah penerapan CPIB. Data dikumpulkan melalui observasi langsung dan wawancara terhadap kelompok yang terdiri atas delapan pembudidaya ikan di desa tersebut. Kinerja produksi dan kinerja finansial mengalami peningkatan setelah CPIB diterapkan oleh kelompok pembudidaya. Produksi benih meningkat sekitar 110% dan rasio net benefit-cost (net B/C) meningkat sebesar 73%. Parameter finansial menunjukkan stabilitas yang cukup baik terhadap kenaikan harga pakan dan penurunan harga jual benih. Hasil penelitian menunjukkan indikasi kuat bahwa penerapan CPIB memberikan dampak positif, yaitu tersedianya pasokan benih nila berkualitas secara berkelanjutan.

Abstract

Evaluation of the Indonesian pearl market is still dominated by trade analysis, while integration of export data with field information on supply chains and market dynamics has been limited. This study aims to evaluate the pearl and pearl oyster (Pinctada maxima) market in Indonesia through an analysis of export trends, changes in trade value, and supply chain conditions during the 2020–2024 period. The study used a survey method approach with primary data collection through field observations and in-depth interviews with 45 respondents consisting of cultivators, traders, and consumers in North Lombok, East Lombok, and West Sumbawa, supported by secondary data from government agencies and the Indonesian Pearl Cultivation Association. The analysis was conducted descriptively using Microsoft Excel and SPSS. The results show that the total volume of Indonesian pearl exports during the observation period reached 46,072 kg with an export value of approximately USD 309.8 million. Although export volume decreased in 2023–2024, export value increased significantly in 2023 to USD 112.9 million, indicating an increase in average prices or a shift towards higher value-added products. Interview findings and field observations revealed that product quality, premium market preferences, and challenges in the supply chain and international marketing standards were the main factors influencing export performance. It was concluded that the competitiveness of the Indonesian pearl market is supported by increasing product value, but supply chain strengthening, quality standardization, and sustainable marketing strategies are still needed to maintain export growth.

Abstract

Cangkring Village has various fishery resources, including ponds, fishponds, and access to waters that support fish farming. The Lecturer Returning Home Program aims to disseminate innovations in systems and appropriate technologies for integrated grouper fish farming through survey and training activities. This study used a survey method combined with a descriptive approach. Sampling was carried out using purposive sampling to collect data from fish farmers in Cangkring Village. The survey research was conducted to identify and analyze the potential for grouper (Epinephelus sp.) nursery and rearing based on natural resources in Cangkring Village, Indramayu. Field observations, questionnaires, and interviews were used to collect data. The recommended stocking density is around 32 fish/m3 for grouper fish rearing in KJT measuring 3×6×1 m for an initial weight of 100‒200 g, and 1,500‒2,000 fish/m3 for grouper seeds in KJT measuring 1.5×1.0×0.5 m to 2.5×1.25×0.8 m. Trash fish have great potential for the development of grouper fish breeding in tanks and ponds as well as rearing in floating net cages/floating net cages (KJT) in the estuary waters of the Cimanuk River, Cangkring Village. In addition, the coastal waters and estuaries of Cangkring Village are rich in rebon shrimp, with an abundance of around 900‒1800 fish/L. The larger the fish seeds, the lower the stocking density. This community empowerment activity is an alternative for the community to improve education and skills in fish farming which can later increase income through an integrated system of grouper nursery and rearing based on natural resources.

Abstract. Diatin I, Effendi I, Taufik MA. 2020. The production function and profitability analysis of Gracilaria sp. seaweed polyculture with milkfish (Chanos chanos) and black tiger shrimp (Penaeus monodon). Biodiversitas 21: 4747-4754. Gracilaria seaweed is the main ingredient for making agar as a source of food and industry. Gracilaria culture in ponds with a polyculture system is one of the potential seaweed cultivation in Indonesia. This study was aimed to analyze the productivity, production input optimation, and profitability on the polyculture system of Gracilaria sp. with milkfish (Chanos chanos) and black tiger shrimp (Penaeus monodon). The survey method was used to notify the seaweed farmers from Indramayu, West Java, Indonesia. The study data were obtained from all seaweed polyculture farmers populations in the observational location by census containing two farmers groups, namely Gracilaria sp. with milkfish and black tiger shrimp (GMS symbol) and Gracilaria sp. with milkfish (GM symbol) polyculture system. This study resulted that GMS polyculture system obtained higher productivity than GM polyculture system. The GMS business scale was in the increasing return to scale condition, while GM was in the decreasing return to scale condition. The optimal condition of GMS polyculture system was performed by improving the black tiger shrimp seed input, milkfish seed, and milkfish feed, besides declining the working hours, while GM polyculture system was performed by decreasing the milkfish feed and farmers working hours. When the optimal condition is applied to the GMS polyculture system, then the business profit reaches five times, resulting in an increased profit margin of 112% with R/C becomes 134%. Meanwhile, GM polyculture system only reaches 65% business profit, 65% profit margin, and 25% R/C. The investment payback period from both polyculture systems became shorter. The application of production input efficiency on the GMS polyculture system is more prospective than GM polyculture system. &nbsp;

Abstract. Sahibuddin MQ, Effendi I, Diatin I, Budiardi T, Setiawati M. 2025. Growth and survival rate of post-puerulus spiny lobster Panulirus homarus at different rearing systems. Biodiversitas 26: 6285-6304. Mariculture of lobsters utilizes Floating Net Cages (FNC), Submersible Net Cages (SNC), and Bottom Net Cages (BNC). This study analyzed the growth and Survival Rate (SR) of post-puerulus Panulirus homarus in these three rearing systems. Post-puerulus individuals (0.86±0.06 cm carapace length; 0.28±0.04 g body weight) were reared in net cages (height 0.8 m; diameter 1 m) at a stocking density of 100 individuals cage-1, with three replicates. The lobsters were fed a moist diet once daily (4:00-5:00 PM). The different rearing system significantly influenced specific growth rate (SGR), Absolute Growth Rate (AGR), total molting, Feed Conversion Ratio (FCR), Intermoult Period (IMP), and SR. The FNC and BNC treatments demonstrated the highest SGR (p: 0.012), at 2.80±0.022% day-1 and 2.76±0.078% day-1, respectively. These treatments also produced the highest AGR (p: 0.013), at 0.07±0.004 g day-1 and 0.06±0.006 g day-1, respectively. The highest total molting (p: 0.025) occurred in the FNC (45.33±9.074 times cage-1) and BNC (43.67±5.033 times cage-1) treatments. The BNC treatment achieved the lowest FCR (7.34±0.372), which was not significantly different from FNC but was significantly lower than SNC (p: 0.032). The FNC treatment resulted in the shortest IMP (14.37±0.38 days, p: 0.000), while the highest SR was observed in the BNC treatment (71.00±2.00%, p: 0.000). Additionally, the lowest glucose (14.14±1.58 mg dL-1, p: 0.031) and total hemocyte count (1.81±0.29x107 cells mL-1, p: 0.000) were recorded in the BNC treatment. These findings indicate that the BNC treatment provided the highest SR and the lowest stress response for post-puerulus P. homarus.
