This study aims to evaluate the minimum demand for water and land in Vertical Aquaculture in RAS on eel through production performance studies and business analysis. This study was conducted on 4 treatments and 3 replications, covering water requirements of 325 mL/day (A), 340 mL/day (B), 370 mL/day (C), and 400 mL/day (D). Elver eels weighing 17.05 ± 0.88 g were reared for 60 days in VAR. The results showed that the difference in water requirements given to eel elver gave an equally good effect between treatments for production performance parameters. The highest water efficiency in this study was produced in treatment A with consumption of water volume requirement of 0.77 L/Kg eel/day and consumption of new water requirement of 10.66 L/Kg eel/year. Aquaculture business analysis shows that VAR technol...

Soft shell mud crab is a crab mangrove swamp phase moult (moulting). The methods used in the process of cultivation a soft shell mud crab is cutting of claws and Foot Paths methods, popey, and natural. The purpose of this research to determine the level of the highest efficiency among these methods by analyzing the survival rate of survival, growth rate, the amount of time molting crabs, crab molting time, growth of biomass as well as cost analysis. The seeds used was 7.49±0.21 cm in length and 110.52 ± 2.70 g in weight. The results showed that the average of survival rate for all treatment are 88,89-92,59% (P>0,05). The highest growth rate was in the treatment of cutting claws foot paths at 2.92% (P 0.05), but significantly different with growth rate of daily weight (P <0.05). In general, the production of soft shell mangrove crab natural treatment is more efficient than cutting of claws and f...

Optimizing the water level will affect the substitution of respiration energy with energy to grow. In addition, the water level information is related to the efficiency of water use for eel production in the future. Information on water level for eel production is still very limited, so this research is necessary to do. A total of 120 eel elver (initial weight 13.66 ± 0.09 g) were collected from eel companies in Bogor City, Indonesia. Fish were reared in vertical aquaculture systems with a stocking density of 10 fish per container for 60 days. The artificial feed containing 55% protein given as much as 3–5% of the biomass. Absorption and water replacement were done 20% per day. The result of this research showed that fish weight increased with an average of 33.45 ± 0.33 g. Different water levels had an impact to KKb, SGOT, ALP, and H...

This study aims to analyze the production performance and economic analysis of catfish on aquaponics technology with floating raft systems. This research was conducted descriptively with two treatments and four replications. The treatments included fish sizes, which were 6-9 cm (A) and 3-4 cm (B). The fish used were fish with an initial weight of 7.13±1.30 g and 4.11±0.43 g, the plant used was water spinach (Ipomoea reptans poir) with an initial height of 8-10 cm. The results showed that there was a trend of increasing fish weight during the study from 7.13±1.30 g and 4.11±0.43 g to 110.02±6.09 g and 86.44±5.00 g at the end of the study. . The survival rate value during the study was 100% for all treatments, the feed conversion value ranged from 1.48-1.59. The highest specific weight growth rate was 1.60%/day. Water spinach production during catfish rearing can be done for 3 ha...

This information is very important in the development of future cultivation technology. This study aims to analyze the oxygen uptake of A. bicolor bicolor through gills and skin, blood biochemistry, blood image and histology to air exposure. Eels were exposed to air for one hour (A), two hours (B) and three hours (C), and eels in the water were used as control. A total of 66 fish (77.68±1.54 g) of eels were imported from Bogor City, Indonesia. Oxygen uptake from the air through the gills and skin reduced with longer exposure time. After 3 hours of exposure time, the percentage of oxygen uptake through the gills decreased from 64.52% to 54.29% and the percentage of oxygen uptake through the skin increased from 35.48% to 45.71%.

The aim of this study was to determine the optimum maintenance system of elver (Anguilla bicolor bicolor) on a wet, moist and dry system through production performance studies and physiological responses. The research was conducted from August to September 2018 at the Production Technic and Management of Aquaculture Laboratory, Department of Aquaculture, IPB University. A completely randomized design with 5 treatments and 3 replications was used in this study, namely treatment with high water wet system 0% of body height (A), high water wet system 50% of body height (B), high water wet system 100% of body height (C), moist system (D), and dry system (E). The body weight of elver was 18.80 ± 0.62 g which derived from fish cultivator in Bogor, West Java. Fish was fed 3 times per day at satiation with commercial feed which a protein content of 50%.
