Abstract

This study aimed to analyze the effect of soaking the extracts of Gynura procumbens leaves with different concentrations on wound healing of catfish infected with Edwardsiella tarda bacteria. This research was conducted at the Wet Laboratory of the Fish Quarantine and Quality Control Agency of Padang, West Sumatra. This study used an experimental method with a completely randomized design (CRD) consisting of 3 treatments and 4 replications. The treatment of this research was the concentration of the Gynura procumbens leaves consisting of treatment P1 = 2000 ppm; treatment P2 = 3000 ppm and treatment P3 = 4000 ppm. Based on the analysis of variance, the concentration of the leaf extract had a significant effect on wound shrinkage. Duncan's follow-up test (DMRT) showed that the treatment was P1; P2; and P3 there are significant differences in each treatment. it was shown that Gynura procumbens leaf extract with different concentrations had no significant effect (p> 0.05) on the survival of catfish. The lowest survival rate in treatment P1 was 66.67%, and in treatment P2 and P3 was 100%. The best results were found in the P2 treatment of 80.20% on wound shrinkage and 100% on survival rate.

Abstract

This study aimed to analyze the effect of the frequency of commercial feeding on the survival and growth of Asang fish larvae. This research was conducted from August to October 2021 at the Integrated Laboratory of the Faculty of Fisheries and Marine Sciences, Bung Hatta University, Padang, West Sumatra. This study used an experimental method with 3 treatments and 4 replications. The treatments in this study were Treatment A = Feed frequency 2 times a day; Treatment B = Feed frequency 3 times a day; and Treatment C = Feed frequency 4 times a day. Parameters observed in this study were survival of fish larvae (%), specific growth rate (%/day), absolute weight growth (mg), absolute length growth (mm), feed utilization efficiency and water quality. The data obtained from the research results were analyzed by one way ANOVA using SPSS 26.0 software. The results showed that the frequency of commercial feeding had a significant effect on the survival and absolute length growth of Asang fish larvae (P<0.05) and had no significant effect on the absolute weight growth of Asang fish larvae (P>0.05). Treatment C was the best frequency which resulted in the highest absolute survival (35.78±2.00), growth in absolute weight of ang fish larvae (15.03±1.64 mg) and length (5.03±0.16 mm). feeding according to gastric emptying of Asang fish larvae.

Abstract

Ectoparasites pose a significant threat to the health and productivity of vaname shrimp (Litopenaeus vannamei) in aquaculture settings, particularly in tropical regions. This study aimed to assess the prevalence, intensity, and dominance of ectoparasites in vaname shrimp ponds in Padang Pariaman, West Sumatra, and to identify factors influencing their distribution. Sampling was conducted across five different pond stations, with each station subjected to regular water quality assessments, temperature monitoring, and parasitological examinations. Ectoparasites were identified and quantified using standard microscopic techniques to determine prevalence, intensity, and dominance. Results indicated that Station II had the highest prevalence (100%) and intensity (69) of ectoparasites, likely due to poor water quality, fluctuating temperatures, and inadequate pond management practices. In contrast, Stations I, III, IV, and V exhibited lower levels of ectoparasite infestation, with Station I having moderate prevalence (80%) and intensity (21) and the remaining stations showing relatively low infestation levels. The dominant ectoparasites identified were Epystylis sp, Zoothamnium sp, Vorticella sp, and Ichthyobodo sp, with varying levels of dominance across the stations, suggesting a correlation with environmental conditions and pond management practices. Effective management of water quality, stocking densities, and regular monitoring can help mitigate ectoparasite infestations in shrimp ponds. This research provides essential insights into sustainable shrimp aquaculture practices, emphasizing the importance of improved pond management strategies to enhance shrimp health and productivity while minimizing the impact of ectoparasites on aquaculture systems in tropical regions.
