Abstract

Gurami (Osphronemus gouramy) merupakan komoditas ikan air tawar yang memiliki nilai ekonomi tinggi dengan permasalahan tingkat kematian yang tinggi pada tahap larva dan benih hingga 50-70%. Upaya pencegahan pada sistem budidaya sedang diarahkan pada penggunaan imunostimulan dari bahan alami salah satunya kulit Manggis karena mengandung senyawa xantone yang cukup kuat sebagai antioksidan, antiproliferartif, dan antimicrobial. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan jenis tepung kulit manggis (Garcinia mangostana) yang berbeda pada pakan terhadap kelangsungan hidup benih ikan gurami (Osphronemus gouramy) berukuran 3-4 cm selama 30 hari. Penelitian ini menggunakan metode eksperimen dengan 4 perlakuan yakni penambahan tepung kulit Manggis sebanyak 0, 5, 10 dan 15gr/kg pakan. Data yang diamati adalah kelangsungan hidup benih ikan gurami dengan parameter pendukung kualitas air meliputi suhu dan DO. Pengolahan data dilakukan dengan menggunakan perhitungan analisis varians (ANOVA) dengan membandingkan nilai signifikansi uji F tabel pada taraf 5%. Rata-rata nilai kelangsungan hidup benih ikan gurami (Osphronemus gouramy) pada perlakuan A sebesar 34%, perlakuan B sebesar 58%, perlakuan C sebesar 68%, dan terakhir perlakuan D sebesar 84%. Hasil penelitian menunjukkan adanya pengaruh pemberian tepung kulit manggis (Garcinia mangostana) dimana pada perlakuan D dengan dosis 15 gr/kg pakan dapat meningkatkan kelangsungan hidup benih ikan gurami (Osphronemus gouramy) sebesar 84%. Data parameter kualitas air diperoleh suhu berkisar antara 27,2-28,6°C dan kandungan oksigen terlarut (DO) yaitu 6,8-7,8 ppm. Saran untuk penelitian selanjutnya, yaitu menggunakan alternatif penambahan pakan alami yang berbeda dan ukuran benih ikan yang berbeda untuk menambah informasi bagi keberlanjutan budidaya.

Abstract

The development of ornamental fish in Indonesia is increasing, especially for freshwater ornamental fish. One of the freshwater ornamental fish that is in great demand by the people today is the guppy fish (Poecilia reticulata). Water fleas (Daphnia sp) is one type of natural food consumed by freshwater fish species. Feeding fish seed is an important factor that must be considered. The purpose of this study was to determine the optimal dose of natural feed Daphnia sp for the absolute growth weight of seeds guppy fish (Poecilia reticulata) within 5 — 45 days. This study used an experimental method with complete random design consist of 5 experiments and 5 repetitions. Treatment A uses a dose of 4%, B; 6%, C ; 8%, D ; 10% and E ; 12%. The test animals were guppy fish seeds from 5-45 days old with an average weight of 0,2 g/tail. The stocking density of guppy is 3 fish/lt and the experimental media used fresh water with a volume of 3 lt/tub. The results showed that experiment C giving the highest average on the growth of guppy weight on the aged of 5-45 days with a height of 0,94 g/tail. The water quality data during the study obtained water temperatures range from 27.2°C – 27.9°C, acidity levels range from 7,3 - 7,8 and dissolved oxygen range from 5,2 - 5,7 ppm.

Abstract

Vaname shrimp (Litopenaeus Vannamei) is one of Indonesia's fishery commodities with high economic value. Vaname shrimp production in Indonesia continues to increase. However, obstacles sometimes arise in cultivation activities, such as the emergence of shrimp diseases and poor water quality. High stocking density and shrimp feeding can cause a decline in water quality. In addition, pond water quality is influenced by pond location and the surrounding environment, such as agriculture, settlements, mangroves, and the sea. This causes ponds to have different water qualities. One of the diseases that often attacks shrimp farming is caused by the bacterium Vibrio sp. The abundance of Vibrio sp. bacteria is closely related to pond water quality and the environmental conditions around the pond. The methods used were TPC testing and multiple linear regression testing. Based on the results of the study, the abundance of Vibrio sp. bacteria in pond A was the highest at 8.3 x 102, and pond C had the lowest at 3.1 x 102. Water quality testing in three different ponds showed safe limits for cultivation, except for nitrite testing. Based on the simple linear regression test, the water quality parameters that significantly affect the abundance of Vibrio sp. bacteria are pH, temperature, and nitrite.

Abstract

Vaname shrimp is one of the export commodities with high economic value. Therefore, to meet increasing market demand, it is necessary to improve aquaculture productivity. However, the development of vaname shrimp farming in Indonesia faces several challenges, including the emergence of viral, fungal, and bacterial diseases (Astria et al., 2022). Vibrio sp. bacteria can cause bacterial infections and are opportunistic in nature. Vibrio sp. can attack shrimp at all stages and may lead to decreased production yields (Astria et al., 2022). Generally, farmers control bacterial diseases by adding antimicrobial compounds. However, bacterial disease control in vaname shrimp culture can also be carried out using hydrogen peroxide (Astria et al., 2022). This study examined the effect of different doses of hydrogen peroxide in suppressing Vibrio sp. bacteria using a Completely Randomized Design (CRD). The doses used were 7 ppm, 9 ppm, 11 ppm, 13 ppm, and 15 ppm, with five treatments and five replications. The results showed that the application of different doses of hydrogen peroxide had a significant effect based on the One Way ANOVA test (0.00 < 0.05). The lowest effectiveness was observed in treatment 1 (7 ppm), while the highest effectiveness was found in treatment 5 (15 ppm). Although hydrogen peroxide was able to reduce the number of Vibrio sp. bacterial colonies, the doses used in this study were not able to completely eliminate the colonies (0 cfu/ml).

Abstract

Based on data from FAO (Food and Agriculture Organization of The United Nations), it has been predicted that the aquaculture subsector will become one of the most relied-upon resources in the future, especially in meeting food needs, fish-based nutritional needs, and empowering the global community's economy (FAO, 2016). Catfish is a type of freshwater fish that can grow and develop well because it can be cultivated in limited land areas (Marsela, 2018). The frequency of feeding is one of the important factors that need to be considered in catfish farming. To determine the effect of different feeding frequencies on the absolute weight of dumbo catfish, a study was conducted using an experimental design called the Completely Randomized Design (CRD), with 3 treatments and a total of 8 replications. The test treatments were as follows: Treatment 1 (feeding twice a day), Treatment 2 (feeding three times a day), and Treatment 3 (feeding four times a day). The results of the ANOVA test showed a significant value of 0.000 (P < 0.05), indicating a significant difference in each of the different feeding frequencies. The analysis of the Least Significant Difference (LSD) test at a 5% significance level also showed that the relationship between each treatment had a significant value of 0.000 (P < 0.05). The average absolute weight of the fish for Treatment 1 was 12.99 grams, for Treatment 2 was 15.03 grams, and for Treatment 3 was 17.03 grams. The highest growth in the absolute weight of dumbo catfish fry occurred in Treatment 3 (feeding four times a day).
