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

Microcapsules are small round particles with uniform walls or layers around them that generally have a diameter from 0.2 to 5000 µm. Microencapsulation is a process that converts solid or liquid materials into capsule form which aims to protect and maintain active ingredients from environmental influences such as humidity, high temperature, light exposure, or oxidation processes. Microcapsule formation can be done using the crosslink method. Microcapsule size is affected by the stirring speed of the encapsulator machine. During microencapsulation of fish meal with eggs and gelatin using the crosslink method, the stirring speed is 3000 rpm, 3500 rpm, 4000 rpm, 4500 rpm, and 5000 rpm. In the microencapsulation process of fish meal with eggs and gelatin, the smallest average diameter at a speed of 5000 rpm, which is 18.220 ± 3.3 µm and has a yield of 26% while the largest diameter at a speed of 3000 rpm, which is 33.53 ± 4.8 µm and has a yield of 28.4%. Based on the results of the Tukey SPSS test, the speeds of 3000 rpm (33.53 ± 4.8 µm), 3500 rpm (30.25 ± 4.4 µm), 4000 rpm (26.30 ± 3.5 µm), 4500 rpm (22.50 ± 4.1 µm), and 5000 rpm (18.220 ± 3.3 µm) were very significantly different (P <0.05) in each treatment.

Abstract

Kedonganan Beach, located in Kuta District, is one of Bali's coastal areas with significant marine resource potential. Most of the local population works as fishermen due to the village's location, bordered by the sea on both the west and east sides. This makes the majority of its residents engaged in the fisheries and marine sectors, including as fishers. One of the fish species with high potential, and a primary catch for fishermen in the Kedonganan area, is tuna. The method used in this study involvedcollecting data through questionnaires distributed via Google Forms for greater efficiency. The goal of this research is to develop the "Tongkol Membara" (Spicy Tuna) product into a micro, small, and medium enterprise (MSME). This requires public interest, especially from the fisherwomen, in the production of this product. The results from seven respondents indicated a 85.7% interest in developing the tuna chili sauce business. Most also expressed interest in participating in a series of activities and continuing the "Tongkol Membara" business. However, 28.5% of respondents were not interested in forming new groups for fisherwomen (BuLayan) because they already belong to existing fisher groups in their respective communities.

Abstract

Guppy fish (Poecilia reticulata) is a popular ornamental fish because of their unique color patterns, the color of ornamental fish will fade if their feed does not contain enough pigmentation to keep them bright. This study aimed to determine the effect of adding Spirulina sp. powder with different dosage to the feed on the color brightness of guppy fish. This study used a completely randomized design (CRD) with five treatments (feed added with Spirulina sp. powder as much as 0%, 0.3%, 0.6%, 0.9%, and 1.2%) and three replications. The test fish were male HB Red guppy fish with a size of 3 cm and a density of 3 fish/aquarium. Water changes (siphoning) was done every morning, and feeding was done twice a day. The parameters observed in this study were the chroma value, survival rate, and water quality. The result showed that the effect of adding Spirulina sp. powder to the feed at a dose of 0.9% and 1.2% had a significant effect on the color brightness. The survival rate indicates that the outcomes were not significantly different between treatments from a 100% success rate. The adding of Spirulina sp. powder increases the brightness of Guppy fish. The brightness color is very important in the Guppy fish farming, because color is the main indicator in ornamental fish. The water has a good quality, with an average temperature of 25.8-26°C and a pH of 7.9-8.0.

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.

Abstract

Tilapia (Oreochromis niloticus) is one of the freshwater fish commodities with significant economic value. The stocking density of a cultivation container is one of the principles that need to be understood, since the denser the stocking in a container, the more competition for feed and oxygen there will be, which can negatively impact fish health. Determining the right stocking density and vitamin C supplementation can be a solution for farmers in maintaining fish health to increase productivity. The purpose of this research was to determine the best stocking density through vitamin C supplementation as seen from the growth data and survival of tilapia during 30 days of maintenance. The research method that will be used is experimental with a Completely Randomized Design. The research consisted of a stocking density treatment of 15 fish/container, a stocking density treatment of 25 fish/container, and a stocking density treatment of 35 fish/container. Each treatment will be given 3 repetitions. Vitamin C supplementation is given in the feed with a dose of 150 mg/kg of feed. The cultivation container used has a volume of 15 L of water as a cultivation medium. Growth and survival data will be analyzed using SPSS and water quality data as supporting data will be analyzed using Ms. Excel and presented descriptively quantitatively. The results of the research showed that the highest length, weight, and survival values were in treatment A (15 fish/L) with a length growth of 2.43 cm and a weight of 2.42 grams and a survival rate of 86.63%. The results of the ANOVA analysis showed that the stocking density treatment had a significant effect on the length of tilapia, but did not have a significant effect on the weight and survival of the fish. The water quality conditions were still at the optimal standard quality values for tilapia maintenance in all treatments.

Abstract

Tilapia (Oreochromis niloticus) has great potential in aquaculture due to its fast growth and delicious meat. However, challenges in providing quality feed and low nutrient intake hamper production. Administration of starfruit extract, rich in vitamin C and antibacterial compounds, can improve feed quality and support fish growth. Research shows that the addition of this extract can increase the weight, length, and survival of tilapia. Thus, using starfruit as a feed supplement at UPR Sumber Rezeki, Palembang, is expected to increase tilapia aquaculture productivity. Tilapia maintenance was carried out for 30 days, using 2 nets in a tarpaulin pond. The first net (P0) is for tilapia maintenance without the addition of starfruit extract, while the second net is for tilapia maintenance with the addition of starfruit extract (P1). Tilapia maintenance with periodic fasting for 30 days resulted in absolute length growth of 3.60 cm, absolute weight growth of 14.30 g, and 100% survival. The results of tilapia maintenance are classified as good compared to maintenance without the addition of starfruit extract.
