ABSTRACT The study aimed to analyze the efficacy of Aeromonas hydrophila formalin-killed cells (FKC) and lipopolysaccharides (LPS) vaccines in maternal immunity of tilapia broodstock and the resistance of the offsprings. This study consisted of two consecutive studies. Firstly, the broodstocks were vaccinated with PBS (non-vaccinated), FKC, LPS, and combinations of FKC and LPS. Secondly, the offsprings from both the vaccinated and non‒vaccinated broodstock were vaccinated with the same vaccine for broodstock by immersion method. After vaccination, the offsprings were challenged with pathogenic A. hydrophila. Antibody level and lysozyme were measured in the broodstock, egg, and offsprings. In the first experiment, the result showed that vaccinated broodstock and their offsprings had delivered a significant antibody level and lysozyme activity compared with the control. The highest relative percent survival (RPS) of offspring resulted from the combination of FKC and LPS vaccinated broodstock at 5, 10, and 15 days post-hatching at 85.00%, 75.23%, and 67.56%, respectively. The second experiment showed vaccinated offsprings produced from vaccinated broodstock had a higher RPS than the RPS of vaccinated offsprings which produced from non-vaccinated broodstock. In conclusion, vaccination that using a combination of FKC and LPS vaccine in broodstock potentially improved the maternal immunity and protect their offspring from A. hydrophila infection. Keywords: Aeromonas hydrophila, antibody, maternal immunity, tilapia, vaccination ABSTRAK Penelitian ini bertujuan menganalisis efikasi vaksin formalin-killed cells (FKC) dan lipopolisakarida (LPS) Aeromonas hydrophila pada imunitas maternal induk ikan nila dan ketahanan benih yang dihasilkan. Dalam penelitian ini, terdapat dua penelitian. Pertama, induk ikan nila divaksin dengan PBS (non-vaksinasi), vaksin FKC, LPS, dan kombinasi vaksin FKC dan LPS. Benih selanjutnya diuji ditantang dengan menggunakan patogen A. hydrophila pada 5, 10, dan 15 hari pasca menetas. Kedua, benih yang dihasilkan oleh induk yang telah divaksinasi dan induk yang tidak divaksinasi tersebut divaksin dengan vaksin yang sama seperti pada induk dengan metode imersi. Setelah vaksinasi, keturunan diuji tantang dengan patogen A. hydrophila. Tingkat antibodi dan lisozim diukur pada induk, telur, dan benih. Pada percobaan pertama, hasilnya menunjukkan bahwa induk yang divaksinasi dan benih menunjukkan tingkat antibodi dan aktivitas lisozim yang signifikan dibandingkan dengan kontrol. Persentase kelangsungan hidup relatif (RPS) tertinggi benih yang dihasilkan dari induk yang divaksinasi FKC dan LPS masing-masing pada 5,10, dan 15 hari pascatetas pada 85,00%; 75,23%; dan 67,56%. Percobaan kedua menunjukkan bahwa benih yang divaksinasi dari induk yang divaksin menunjukkan RPS yang lebih baik daripada benih yang divaksinasi dari induk yang tidak divaksin. Vaksinasi menggunakan kombinasi FKC dan LPS pada induk berpotensi meningkatkan kekebalan induk dan melindungi benih dari infeksi A. hydrophila.

Bacterial isolation was carried out on sea bass Lates calcarifer juvenile with black body syndrome (BBS) and isolates of Pseudomonas stutzeri L01, Vibrio harveyi, Bacillus cereus, Salinicoccus roseus, and Pseudomonas stutzeri L02 were obtained. Microscopic anatomical pathology of each bacterium needs to be done to determine its pathogenicity. This study aims to compare the degree of damage to sea bass juveniles' liver and kidney organs through histopathological observations due to bacterial infections that cause BBS. The degree of histopathological damage was determined by scoring histopathological changes in the tissue under a microscope with a magnification of 40×10 in five fields of view. The data obtained were analyzed using SPSS 24 software and further tested with Kruskal-Wallis and Post Hoc (Mann Whitney). The results showed that fish liver and kidney organs in all treatments experienced necrosis compared to the control treatment, but not significantly different between bacterial infection treatments. Histopathological observations of kidney and liver organs of sea bass juveniles infected with bacteria that cause BBS show necrosis damage that was classified as normal and mild.

Catfish (Clarias sp.) aquaculture in Kediri Regency, East Java, faces challenges due to the limited availability of high-quality broodstock and the lack of mastery in catfish spawning technologies, such as broodstock selection and the use of natural materials and probiotics to accelerate gonad maturation. These issues formed the basis for implementing a community empowerment program titled "Empowering Fish Farmers through Reproductive Process Education to Improve Catfish Seed Productivity in Kediri Regency." The program aimed to educate fish farmers on proper catfish breeding techniques, from broodstock selection to the use of probiotics and pine fruit extract to enhance gonad maturation and broodstock rematuration, through outreach activities. The community service program included public outreach to fish farming communities and discussions on program sustainability with the Kediri Regency Fisheries Department. Key stakeholders involved in the program included IPB University, the Fisheries Department of Kediri Regency, fisheries extension officers (Ministry of Marine Affairs and Fisheries), and catfish farmer groups in the region. The outreach began with a pre-test and concluded with a post-test to evaluate the program’s effectiveness. The materials covered included broodstock selection, application of pine fruit extract and probiotics for accelerating gonad maturation and rematuration. The community responded positively, as evidenced by an increase in average test scores from 78.42 (pre-test) to 92.63 (post-test), indicating that participants had gained a general understanding of catfish farming techniques and, through the outreach, comprehended the technology needed to produce high-quality broodstock.
