Abstract

One of major problem of siamse catfish (Pangasianodon hypophthalmus) culture is Edwardsiliosis bacterial disease of Edwardsiella ictaluri, causes economic losses because it causes high mortality and reduces the quality of fishery products. Currently, the use of antibiotics as an effort to control the disease has been prohibited due to the impact of residual hazards, resistance and decreased food safety value. Therefore we need an alternative solution that is effective, efficient and applicable through the vaccines application. The aim of this research was to analyze the effectiveness of the Whole cell Edwardsiella ictaluri vaccine with different doses and different application methods to protect Siamese catfish (Pangasianodon hypophthalmus) from Edwardsiellosis disease. The research was conducted using a completely randomized design (CRD) method consisting of 3 methods, namely oral vaccine, immersion vaccine, and injection vaccine. Each method consisted of 4 different dose treatments with 3 replications. The results showed that the vaccine application using different methods resulted in different survival rates, relative survival rates, specific growth rates and mean time to death. The oral vaccine method using each different dose resulted in the best survival rate, relative survival percentage, and mean time to death. The immersion vaccine method with a dose of 10.9 resulted in the highest specific growth rate.

Abstract

Penelitian ini dilakukan untuk mengevaluasi sistem produksi Induk dan calon induk bermutu yang dilakukan oleh Pemerintah Pusat dalam hal ini Kementerian Kelautan dan Perikanan. Sistem Produksi Ikan di Indonesia meliputi produksi calon induk dan induk bermutu. Selain itu, juga dikelompokkan ke dalam habitatnya, yaitu kelompok ikan air tawar, kelompok ikan air laut, dan kelompok ikan air payau. Instansi pemerintah yang bertugas untuk menyediakan ikan bermutu, baik Induk maupun benih adalah unit-unit pelaksana teknis yang ada dibawah Kementerian Kelautan dan Perikanan. Salah satu unit pelaksana teknis air tawar yang ada di wilayah Sumatera adalah Balai Perikanan Budidaya Air Tawar (BPBAT) Sungai Gelam. Balai ini mempunyai kewajiban untuk memenuhi kebutuhan calon induk dan induk bagi pembudidaya, unit pembenihan rakyat (UPR) dan pemerintah daerah atau stakeholder terkait melalui penyaluran bantuan induk dan calon induk. Evaluasi proses pelaksanaan program menunjukkan sebagian besar pelaksanaan program sudah sesuai dengan perencanaan, dimana Balai telah bisa menghasilkan varietas induk unggul baru untuk ikan Patin (Pangasianodon hypopthalmus) yang diberi nama Induk Ikan Patin Pustina. Kelebihan induk Pustina ini memiliki pertumbuhan yang cepat, ketahanan terhadap penyakit (Edwardsiella ictaluri dan Aeromonas hydrophyla), efisiensi dalam pakan, ketahanan terhadap kondisi lingkungan yang buruk (karena amonia) dan bisa dibudidayakan di lahan gambut dengan pH yang rendah.
PERFORMA VAKSIN IKAN ‘TRIVALEN-SA’ PASCAPENYIMPANAN SELAMA 12 BULAN UNTUK PENCEGAHAN KO-INFEKSI STREPTOCOCCOSIS DAN MOTILE AEROMONAS SEPTICEMIA PADA IKAN NILA (Oreochromis niloticus) Kholidin, Edy Barkat; Wadjdy, Edy Farid; Sudarmaji, Sudarmaji; Sirodiana, Sirodiana; Abduh, Muhammad; Saputra, Adang; Murniasih, Siti; Taukhid, Taukhid

Abstract

Riset ini bertujuan untuk mengevaluasi efikasi dan keamanan vaksin ikan ‘Trivalen-SA’ pascapenyimpanan selama 12 bulan untuk pencegahan ko-infeksi streptococcosis dan motile Aeromonas septicemia (MAS) pada ikan nila (Oreochromis niloticus). Ikan uji yang digunakan adalah ikan nila yang sudah specific pathogen free dengan bobot 8 ± 1,2 g. Perlakuan yang diberikan adalah aplikasi vaksin melalui: (1) Injeksi satu dosis (0,1 mL per ekor), (2) Injeksi dua dosis (0,2 mL per ekor), (3) Perendaman dalam larutan vaksin pada konsentrasi 107 CFU mL-1,(4) Injeksi 0,1 mL phosphate buffered saline (PBS) sebagai kontrol positif, dan (5) Perendaman dalam air segar selama 30 menit sebagai kontrol negatif.  Efikasi vaksin dievaluasi dengan nilai relative percent survival (RPS) melalui uji tantang terhadap kedua jenis bakteri infektif penyusun formula vaksin. Uji keamanan vaksin dilakukan sesuai metode standar pengujian vaksin ikan. Hasil penelitian menunjukkan bahwa vaksin ikan ‘Trivalen-SA’ pada pengujian ini masih aman dan protektif dengan hasil secara kuantitatif lebih baik karena nilai RPS terhadap infeksi bakteri Aeromonas hydrophila berkisar antara 15,79-29,82%; bakteri Streptococcus agalactiae (non-hemolitik) antara 25,92-48,15%, dan bakteri S. agalactiae (β-hemolitik) antara 18,52-40,75%. Proteksi sinergis terhadap ko-infeksi ketiga jenis atau biotipe bakteri adalah 27,37% untuk injeksi satu dosis; 39,57% untuk injeksi dua dosis, dan 22,54% untuk perendaman. Hasil terbaik berdasarkan kinerja sintasan dan pertambahan bobot tubuh ikan nila dengan nilai RPS mencapai 39,57% apabila diberikan vaksin melalui injeksi dua dosis (0,2 mL per ekor).A study was conducted to determine the efficacy and safety of the ‘Trivalen-SA’ fish vaccine after 12 months of storage in preventing co-infection by streptococcosis and motile Aeromonas septicemia (MAS) in tilapia (Oreochromis niloticus). Specific pathogen-free tilapia with a weight of 8 ± 1,2 g were used as the test fish. The treatments included: (1) Injection with a single dose (0.1 mL per fish), (2) Injection with a double dose (0.2 mL per fish), (3) Immersion with the vaccine solution in 107 CFU mL-1, (4) Injection with 0.1 mL phosphate buffered saline (PBS) as a positive control, and (5) Immersion with freshwater for 30 minutes as a negative control. Vaccine efficacy was assessed using relative percent survival (RPS) values obtained from the challenge tests against each bacterial species in the vaccine. Vaccine safety was evaluated according to standard fish vaccine testing protocols. The results showed that the ‘Trivalen-SA’ vaccine in this study remained safe and effective indicated by RPS value against Aeromonas hydrophila ranged from 15.79 to 29.82%, non-hemolytic Streptococcus agalactiae ranged from 25.92 to 48.15%, and β-hemolytic S. agalactiae ranged from 18.52 to 40.75%. The synergistic protection against co-infection by all three bacterial species or biotypes was 27.37% for the single-dose injection, 39.57% for the double-dose injection, and 22.54% for the immersion method.  The best results based on the survival performance and body weight gain of tilapia with an RPS value reached 39.57% when given the vaccine through double-dose injection (0.2 mL per fish).
