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).
