Abstract

The use of automatic feeding equipment can increase the productivity of vannamei shrimp cultivation and harvest yields. This research aimed to determine which of the three feeding methods (manual, 120° autofeeder, and 360° autofeeder) produces greater growth and production results for vannamei shrimp. The shrimp used came from Sura Tani Pemuka which were stocked from 23-25 July 2022 at PL (post larval) age 11. When using a 360° autofeeder with a total area of 5,880 m2 and a density of around 169 individuals/m2. When using a 120° autofeeder with a total area of 2,840 m2 and a density of around 166 fish/m2. The manual method is used with a total area of 2,500 m2 and a density of around 187 individuals/m2. The research method was carried out by means of descriptive observation and analysis. Data collection was carried out during shrimp sampling activities, checking water quality, and harvesting. The research results showed that the use of a 360° autofeeder, 120° autofeeder, and manual resulted in sequential growth performance including: survival rates of 39.37%, 51.47%, and 32.47%; average weight growth of 21.53 gr/head, 17.47 gr/head, and 10.12 gr/head; daily weight growth of 0.31 gr/day, 0.25 gr/day and 0.16 gr/day; and, feed conversion ratios were 1.84, 1.73 and 2.23. The harvest results achieved using the 360° autofeeder, 120° autofeeder, and manual method reached 4558.32 kg, 3670.18 kg, and 1294.965 kg, respectively.

Abstract

Guppy fish is one type of ornamental fish which is in great demand due to its interesting color variations. Color of ornamental fish will be brighter if the feed contains color pigments. The study aims to determine the effect of Astaxanthin supplement in pellets on the color brightness of guppies and to find the best dose of Astaxanthin supplement in pellets on the color brightness of guppies. The method used in the study was complete randomized design (CRD) consisting of five treatments (Astaxanthin supplements of 0%, 2%, 3%, 4% and 5%) and three replications. The experimental fish were male guppy fish Strain HB Red ± 3 cm length with a density of 3 fish/aquarium. Feeding was done twice a day and siphoning was done every afternoon. The parameters observed were Chroma value, survival rate and water quality. The results show that the supplement of Astaxanthin in pellets successfully increase the brightness of guppies and the best dose of Astaxanthin supplement in pellets was 5% with an increase in Chroma value of 4.82%. The survival rate obtained was 100%. Water quality includes an average temperature of 26-27 ℃ and pH of 6-7 and dissolved oxygen (DO) was 6.95-7.93 ppm

Abstract

The high cost of commercial feed in Nirwana tilapia aquaculture leads to elevated production costs and reduced profits. As a solution, the provision of natural feed is proposed as an alternative to reduce production expenses. This study aims to compare the growth of Nirwana tilapia fed with three different natural feeds: Tubifex sp., Chironomus sp. larvae, and maggots. The experiment was conducted using a completely randomized design with three replicates for each treatment. The feeding rate was 3% of the fish’s body weight, administered three times a day. The parameters measured included absolute biomass, absolute length gain, daily growth rate (Specific Growth Rate, SGR), survival rate (SR), and water quality during the 30-day rearing period. The results showed that feeding Nirwana tilapia with Tubifex significantly increased growth compared to the control group (commercial pellets), Chironomus larvae, and maggots. The absolute biomass from Tubifex feeding was 5.23 ± 0.89 g, absolute length was 4.2 ± 7.8 cm, SGR was 1.52 ± 0.33%, and SR was 90%. The next highest growth was seen in Chironomus larvae, followed by maggots, with the control yielding the lowest results.

Abstract

The presence of vibrio bacteria in the breeding pond is one of the important factors that affect the activities of vaname shrimp breeding. Vibrio sp. bacteria in waters can cause losses if the number is above the threshold that should be. The high abundance of Vibrio sp. bacteria in the cultivation environment is an indicator that shows the potential for disease that can reduce the growth rate and survival of shrimp. The purpose of the study was to determine the abundance and dominance of vibrio bacteria in vaname shrimp breeding ponds using the TPC (Total Plate Count) calculation technique. The methods used include bacterial sampling, preparation of tools and materials, making bacterial culture media (NA and TCBS), dilution, bacterial inoculation, and calculating the number of bacterial colonies. The results of the calculation of bacterial abundance showed that there were 9 breeding ponds with different abundances. The highest abundance was found in pond BV1 with a total bacterial value of 9.6 x 105 CFU/ml. Meanwhile, the highest vibrio dominance was found in pond BV4 with a percentage of 43.69%.

Abstract

Tilapia is a commodity cultivated in the rice-fish farming area of Panembangan, Banyumas. Information related to the presence of potential bacteria in the intestines of fish cultivated in rice-fish areas is still low, especially proteolytic bacteria. The purpose of this study was to determine the proportion and activity index of proteolytic bacteria in the intestines of fish. This study used an observation method with a purposive sampling technique. Proteolytic bacteria were isolated from the intestines of tilapia in blocks A and E. The bacteria that were successfully isolated were grown on 2% skim milk agar media with an incubation time of 48 hours and observed at 24-hour intervals. Based on the results of the study, the proportion of proteolytic bacteria in the intestines of tilapia from both blocks was 28% in block A and 44% in block E, respectively. The proteolytic activity index of both blocks had an average of 0.48 for block A and 0.75 for block E. The highest proteolytic activity index was from block A, namely 0.83, and in block E 3.0. Meanwhile, the smallest proteolytic index is 0.17 block E and 0.22 block A.
