This study aimed to evaluate the physiological responses of Asian swamp eel, Monopterus albus during the fasting period at different salinity levels. Fasting period was three days at four levels of salinity, i.e., 0 g L -1 , 3 g L - 1 , 6 g L - 1 , and 9 g L - 1 . The eels were stocked at a density of 200 kg m - 3 . Physiological parameters studied were blood plasma cortisol which was measured by radioimmunoassay method, blood plasma glucose and liver glycogen which were measured by spectrophotometer, blood plasma sodium which was analyzed by Atomic Absorption Spect rophotometer, and osmolality which was measured using osmometer. The results showed that salinity affected the physiological status of the eels. Fasting the eels could increase the blood plasma cortisol levels, but in at higher salinity levels the hormone was lower. Blood plasma sodium levels of the eels increased in line with higher salinity. Fasting the eels at salinity of 0 and 3 g L - 1 was increasing the glucose levels significantly compared to the eel at a salinity of 6 and 9 g L - 1 . In contrary, the liv er glycogen levels were statistically lower in salinity of 0 and 3 g L - 1 compared to the eels at a salinity of 6 and 9 g L - 1 . Fasting the fish for three days at all salinity treatments did not change the condition factor of the eels. The eels were exhibite d the best physiological performance during the three - days fasting period at a salinity of 9 g L - 1 . Abstrak Penelitian ini bertujuan untuk meng evaluasi respons fisiologis ikan belut Monopterus albus pada pemberokan dengan tingkat salinitas yang berbeda.

Belut (Monopterus albus) merupakan ikan air tawar konsumsi hasil tangkapan dari perairan umum yang dijual dalam keadaan hidup dengan harga tinggi dan permintaan yang terus meningkat. Aktivitas penangkapan, transportasi, dan penampungan menimbulkan kematian yang cukup banyak sehingga mengurangi stok dan nilai penerimaan penjualan belut. Penanganan belut pasca-penangkapan dalam air salin dapat menekan tingkat kematian belut, namun dampaknya terhadap keuntungan bisnis belum diketahui. Penelitian ini bertujuan untuk mengevaluasi penampungan dalam air salin terhadap sintasan dan keuntungan usaha penjualan belut hidup. Penelitian dilakukan pada pedagang besar belut hidup di Jawa Tengah yang memperoleh pasokan belut dari berbagai lokasi di Jawa. Belut uji yang diperoleh dari tiga lokasi yaitu Ciamis, Jawa Barat; Cilacap, Jawa Tengah; dan Lumajang, Jawa Timur; masing-masing ditampung terpisah dan dipelihara selama enam hari dalam air tawar (salinitas 0 g/L) dan air tawar yang ditambah garam krosok pada konsentrasi 6 g/L. Hasil menunjukkan bahwa penampungan selama seminggu dalam salinitas 6 g/L menghasilkan tingkat sintasan belut 1,6 kali dibandingkan dengan penampungan dalam air tawar pada semua lokasi asal belut. Sintasan yang lebih tinggi tersebut meningkatkan nilai penerimaan dan keuntungan usaha.Asian swamp eel (Monopterus albus) is a highly-priced freshwater fish collected from natural waters and sold alive in the market with an ever-increasing demand. Fishing methods, transportation, and holding of live eels before being sold frequently result in significant mortality, which eventually reduces the sales revenue from the business. However, post-capture handling of the eel using saline water could reduce the mortality rate, but the impact on business profits has never been determined. This study was aimed to determine the effects of water salinity on the survival of the eels during the holding period and calculate the profit gain from live eel sales. The research was carried out in the facility of a wholesaler of live Asian swamp eel in Central Java which received eel supply from various locations in Java. The samples of eels were originated from three locations, namely Ciamis, West Java; Cilacap, Central Java; and Lumajang, East Java. The eels were placed in separate containers filled with: fresh water (salinity 0 g/L) and freshwater added with salt at concentration 6 g/L for six days. The results showed that six days holding period in salinity of 6 g/L resulted in a higher survival rate of the eels up to 1.6 times compared to the freshwater. This higher survival has increased the revenues and profitability of the live eels sales.

Wadah pemeliharaan merupakan hal yang perlu diperhatikan dan salah satu kunci dalam pertumbuhan, perkembangan, dan produksi kepiting bakau. Salah satu permasalahan yang dihadapi dalam budidaya kepiting bakau adalah kurang tepatnya wadah budidaya yang digunakan. Penelitian ini bertujuan untuk menentukan ukuran wadah dan ketinggian air yang tepat untuk budidaya kepiting bakau, Scylla tranquebarica dilihat dari laju pertumbuhan harian dan periode molting. Penelitian dilakukan di tambak masyarakat Desa Mulaeno Kecamatan Poleang Tengah Kabupaten Bombana Provinsi Sulawesi Tenggara. Hewan Uji berupa kepiting bakau ukuran 57,89 ± 2,18 g ekor-1 sebanyak 54 ekor. Pemeliharaan dilakukan selama 60 hari pada wadah single room (1 ekor/wadah) pada ketinggian air berbeda 30, 50, dan 70 cm dengan ukuran wadah yang berbeda yakni 30 cm x 30 cm, 40 cm x 40 cm, dan 50 cm x 50 cm. Wadah pemeliharaan yang digunakan sebanyak 54 unit terbuat dari bambu yang berbentuk seperti kandang (kerangkeng) ditempatkan scara acak pada tambak. Pakan yang diberikan berupa ikan rucah sebanyak 5% dari bobot tubuh dan diberikan pada pagi dan sore hari. Terdapat sembilan perlakuan dan diulang sebanyak enam kali, yakni P33 (ketinggian air 30 cm, ukuran wadah 30 cm x 30 cm), P35 (ketinggian air 50 cm, ukuran wadah 30 cm x 30 cm), P37 (ketinggian air 70 cm, ukuran wadah 30 cm x 30 cm), P43 (ketinggian air 30 cm, ukuran wadah 40 cm x 40 cm), P45 (ketinggian air 50 cm, ukuran wadah 40 cm x 40 cm), P47 (ketinggian air 70 cm, ukuran wadah 40 cm x 40 cm), P53 (ketinggian air 30 cm, ukuran wadah 50 cm x 50 cm), P55 (ketinggian air 50 cm, ukuran wadah 50 cm x 50 cm), P57 (ketinggian air 70 cm, ukuran wadah 50 cm x 50 cm). Hasil penelitian menunjukkan bahwa tidak ada interaksi antara ukuran wadah dan ketinggian air, serta tidak ada pengaruh nyata terhadap kinerja produksi kepiting bakau. Ukuran wadah 30 cm x 30 cm, ketinggian air 30 cm (P33) lebih efektif dan efisien digunakan pada budidaya kepiting bakau menggunakan sistem single room.Specifications of cage farming plays important roles in the growth, suvival, and expected harvest of farmed mud crab. One of the constraints in mud crab farming is that the cages used are not suitable or preferred for the species. The research aimed to determine the proper cage size and water depth for mud crab culture using the growth rate and molting period as the observed parameters. This research was conducted in a pond located in Mulaeno Village, Bombana Regency Central Poleang, Southeast Sulawesi province. The experiment used 54 mud crabs sized between 50 – 70 g. Each crab was kept in a cage sized 30 cm x 30 cm, 40 cm x 40 cm or 50 cm x 50 cm with a stocking density of 1 ind./cage. The cages were positioned at different water levels (30 cm, 50 cm, and 70 cm). The cages were constructed from bamboo , rectangular in shape, and placed randomly in the pond. The feed (trash fish) was given twice daily (morning and afternoon) as much as 5% of the crab body weight. There were nine treatments and each treatment had six replications, i.e, T33 (water depth 30 cm, cage size 30 x 30 cm), T35 (water depth 50 cm, cage size 30 x 30 cm), T37 (water depth 70 cm, cage size 30 x 30 cm), T43 (water depth 30 cm , cage size 40 x 40 cm), T45 (water depth 50 cm, cage size 40 x 40 cm), T47 (water depth 70 cm, cage size 40 x 40 cm), T53 (water depth 30 cm, cage size 50 x 50 cm), T55 (water depth 50 cm, cage size 50 x 50 cm) , T57 (water depth 70 cm, cage size 50 x 50 cm). The results showed that there were no significant influence of the cage sizes and water depths on the production performance of the mud crab. The cage size 30 x 30 cm, and water depth 30 cm (T33) is more effective and efficient in mud crab farm using a single room system.

Eel (Anguilla bicolor bicolor) rearing activities that develop in Indonesia generally still use a large volume of water. The application of a recirculation system reduces water requirements and at a small volume of water, the load on the container to accommodate water becomes lighter so that several containers can be arranged vertically. This study aims to determine the best water volume in eel rearing with a recirculation system on production performance. This study used a completely randomized design with four treatments and three replications. The treatments, namely the difference in the volume of water (VA) used in the maintenance container, included VA 2.5 L (A), VA 3.5 L (B), VA 4.8 L (C) and VA 5.8 L (D). Eels were reared for 60 days in an aquaverticulture system with a stocking density of 10 fish per container. The test parameters in this study included survival rate (SR), specific growth rate (LPS), absolute weight growth (PBM) and feed conversion (FCR) and coefficient of final weight diversity (KKb). Other parameters analyzed include water and land use analysis. The results showed that aquaverticulture with multilevel containers on eel produced the best water volume of 5.8 L with high production performance (100% survival, specific growth rate 1.60%/day). The volume of water needed to produce 1 kg of eel for 1 year is 27.69 liters and the productivity of aquaculture land is 86.14 kg/m2. During the COVID-19 pandemic, this system design has been applied on a laboratory scale, but has not been applied commercially in the community.

Nursery culture of tilapia (Oreochromis niloticus) is an important segment to support a comprehensive tilapia culture business. Requirements for business sustainability involve the high profitability of the company and high growth of the reared fish. This experiment aimed to observe the profitability aspect, fish growth, water quality, and culture techniques applied in a tilapia farm. The experiment was done using case study method, where Turbo farm, located in Bogor West Java, was used as a model. The data collected involved primary data from field observation and secondary data from interview activities. The results showed that tilapia juvenile had a good growth, and that the water quality (temperature and pH) ranged within optimal range for tilapia culture. At stocing density of 2.000 juvenile per production unit in one cycle, the total production was 68.400 juvenile per year, in which 10% of the total produced juvenile were sold at size of 7-8 cm, while the remaining juveniles were at size 11-12 cm. Price of juvenile at size 7-8 cm was half of the size 11-12 cm, Rp 600 vs Rp 1.200 per juvenile, respectively. The profit of the business was Rp 43.989.000 per year with value of revenue/cost (R/C) ratio 2,29, and payback period (PP) 6,27 year. Based on the previously mentioned profitability parameters, the nursery culture of tilapia performed by Turbo farm was profitable. However, an efficiency of facility use was needed to increase profit and shorten the return on investment period.

The grow-out phase in tilapia culture (Oreochromis niloticus) is a vital business segmentation because it is the final supply chain for fish at consumption size for the general market. This study aims to analyze the managerial aspect, and business profitability in tilapia grow-out culture at the Iwa-ke Oishi Fish Factory in Bogor, West Java. The experiment collected primary data (water quality measurement) and secondary data (interview). The tilapia grow-out culture was done by six farmers who were responsible for happas and ponds that they managed. The results showed that managerial aspects include work units, each of which has a specific role, for example, aquapartners responsible for fish culture activities and investors who provide venture capital. The two roles were linked through a profit-sharing scheme with Fish Factory Iwa-ke Oishi as the collaboration coordinator. Tilapia cultured had good growth performance, as seen from a high survival rate (70.0-82.8%), supported by good water quality with low concentrations of nitrite and nitrite during the culture period (1.5 mg/day). L and 0 mg/L, respectively). Financially, this activity was profitable and promising (payback period of 0.9 years). However, the profit margin could be improved by reducing the variable costs, such as utilizing natural biota as additional feed for tilapia to decrease the feeding cost.
