Abstract

Litopenaeus vannamei is a brackish-water aquaculture commodity that is highly favored by the Indonesian community and represents one of the country’s leading aquaculture products, with production continuing to increase in response to rising domestic and export demand. One of the main factors triggering disease in L. vannamei is the presence of Vibrio sp. bacteria, which are recognized as serious pathogens in various aquaculture organisms and serve as causative agents of bacterial diseases. These bacteria naturally inhabit marine environments and are categorized as opportunistic, meaning they become pathogenic when environmental conditions decline and host health is compromised. Disinfectants are chemical substances used to inhibit or eliminate microorganisms such as bacteria, viruses, and fungi (excluding bacterial spores) on non-living surfaces. One disinfectant material is Smart Care (Intracare B.V., The Netherlands), which contains stabilized hydrogen peroxide with a prolonged-release mechanism. This study employed an experimental method using a Completely Randomized Design (CRD) with four treatments and five replications. The treatments included a control (without H₂O₂) and applications of H₂O₂ at concentrations of 1 ml/L, 2 ml/L, 3 ml/L, and 4 ml/L. The results indicated that the addition of hydrogen peroxide at different concentrations did not produce statistically significant differences in suppressing the growth rate of Vibrio sp. Nevertheless, treatment C (3 ml/L H₂O₂) showed the highest inhibitory effect, with no bacterial colony growth observed. Therefore, the application of H₂O₂ at 3 ml/L demonstrates potential in reducing Vibrio sp. growth and supporting sustainable shrimp aquaculture practices.

Abstract

Guppy fish (Poecilia reticulata) hold high commercial value, particularly the males, due to their aesthetic colors and morphology. This study aims to determine the effect of different soaking durations in honey on the masculinization of guppy larvae and to identify the optimal immersion time. This experimental study utilized a Completely Randomized Design (CRD) with 5 treatments and 5 replications, using a honey dosage of 5 ml/L with soaking durations of: 8 hours, 10 hours, 12 hours, 14 hours, and 16 hours. The results showed that the variation in soaking duration had a significant impact on the percentage of masculinization. The 12-hour soaking treatment yielded the best results, achieving a male percentage of 90.1%. Water quality parameters during the 45-day rearing period remained stable within the optimal range, with temperatures of 23.1–26.9°C, pH of 7.0–7.2, and dissolved oxygen (DO) of 6.1–6.7 ppm. In conclusion, the use of honey as a natural ingredient is effective in significantly inducing male sex differentiation in guppy fish larvae.
