“…Serangan penyakit dapat menyebabkan berbagai dampak negatif bagi usaha perikanan budidaya, antara lain pertumbuhan ikan terganggu, periode pemeliharaan lebih lama, tingginya tingkat konversi pakan, dan bahkan kematian. Berbagai dampak tersebut mengakibatkan usaha budidaya mengalami kerugian ekonomis dalam tingkat tertentu, bahkan dapat secara total menyebabkan gagal panen (Fira et al, 2021;Hakim et al, 2019;Tuwitri et al, 2021;Yuliani et al, 2023). Perkembangan penyakit pada ikan adalah suatu proses yang dinamis dan merupakan interaksi antara inang, jasad pathogen dan lingkungan.…”

“…Jenis ektoparasit yang dapat mengancam budidaya ikan nilem adalah Trichodina sp., Ichthyopthirius multifiliis, Dactylogyrus sp., Gyrodactylus sp., Argulus sp., Learnea sp., Camallanus sp., Tetrahymena, Microsporidians, dan Pallisentis sp. (Adamimawar et al, 2019;Fira et al, 2021;Ghassani et al, 2016;Hernawati, 2015;Mulyana & Mumpuni, 2015;Riwidiharso et al, 2019;Sitompul et al, 2019;Ulkhaq, 2019).

The aims were to do an ectoparasite and pathogenic bacteria inventory of Bonylip barb reared in Banyumas district. Total of 118 fish were randomly taken from Singasari (30 individual), Pabuaran (30 individual), Beji (30 individual) and Jipang (28 individual) villages. This work observed ectoparasite species, prevalence, and intensity as well as pathogenic bacteria species. Ectoparasites were identified based on morphological characteristics observed microscopically and their prevalence and intensity were calculated. Bacterial pathogen was isolated from fish samples showing symptoms of bacterial disease and identified molecularly based on 16s rDNA sequence using BLAST dan phylogenetic analysis. Results showed Trichodina sp. and Monogeneans were found infected fish samples from all location with prevalence was 70-100%. Ichthyophthirius multifiliis was found from all location except Singasari village. Some of fish samples showed fin necrosis and five bacterial isolates were obtained. 16s rDNA marked gene was successfully amplified and sequenced. Based on sequence analysis, five isolates could be clustered into two groups, the first was found only in Singasari village and the second was found in Singasari and Beji villages. Similarity value of 16s rDNA gene sequence these two groups was 99,8%. Result of BLAST and phylogenetic analysis showed that the bacterial pathogens were identified as group of Aeromonas hydrophila complex.

This study aims to determine the potential of Bacillus subtilis probiotic in reducing levels of ammonia, Vibrio sp, and increased production performance in seaworm cultivation (Nereis sp.) under laboratory scale. Observation of the performance of seaworms (Nereis sp.) was carried out every 10 days which included weight gain (gr), length (cm), total biomass (gr), total bacteria (CFU/mL), total Vibrio sp. (CFU/mL), and total Bacillus subtilis (CFU/mL). Water quality measurements include temperature, dissolved oxygen (DO), pH, ammonia, and total organic matter (TOM). Application of probiotics Bacillus subtilis has the potential to reduce ammonia concentration, increase growth, and reduce the abundance of Vibrio sp under laboratory-scale seaworm cultivation. P3 treatment (0.01 mL with a probiotic density of 10 6 CFU/mL) gave the best results by being able to reduce the ammonia concentration by 47.5%. In summary, the probiotic application using the bacteria Bacillus subtilis with different densities able to provide good results in supporting production performance, maintaining the abundance of Vibrio sp., and reducing ammonia concentration in seaworm cultivation. This is the first study to report the performance of seaworm production using probiotic agent, research is still needed to determine the digestive enzyme activity of seaworms given probiotics.

The aim of the research is to monitor the dynamics of microbial number, water quality, and production performance in Pacific white shrimp (Litopenaeus vannamei) cultivation in Bulukumba, South Sulawesi Province, Indonesia, utilizing an intensive system. This research was carried out on seven Pacific white shrimp ponds over the duration of one maintenance cycle (84 days), from November 2019 to February 2020. Interestingly, the results showed that the highest total bacterial counts (TBC) were obtained in pond P3, namely in the range of 0.12-98.0×105 CFU/mL, the highest total Vibrio counts (TVC) were obtained in pond P5, namely in the range of 0.09-2.8×105 CFU/mL, luminous bacterial counts (LBC) were only found in ponds P1, P4, and P5 with the same range values, namely 0-100×103 CFU. The best performance of Pacific white shrimp production was found in pond P2, with a percentage of survival rate (SR) and productivity of 65 percent and 4074.5kg/ha, respectively, and the worst was found in pond P5, with a percentage of survival rate (SR) and productivity of 35 percent and 2583.66 kg/ha, respectively. Finally, the intense culture system used for Pacific white shrimp accumulates dynamics that may alter microbiology, water quality, and production performance.
