This research aimed to examine the effect of baker’s yeast as immunostimulant on growth of nile tilapia and to find out a proper dose of baker’s yeast that promoted optimal growth of fish. Juveniles with an average weight of 31.83 g were obtained from stock available at Aquaculture Study Program of the Faculty of Fisheries and Marine Sciences.  This research was conducted at the experimental ponds located at the Faculty of Fisheries and Marine Sciences for three months. During the experiment, fish was fed with pellet supplemented with baker’s yeast as treatment for four weeks as much as 4%/bw/day, twice daily.  The doses of baker’s yeast consisted of 0, 10, 20, 30, and 40 g/kg pellet. Fish growth including absolute and relative growth was measured at two weeks interval.  Research results showed that  after two weeks of feeding, supplementation of baker’s yeast did not affect the growth of fish but after four weeks of feeding, supplementation of baker’s yeast significantly increased fish growth. Fish fed pellet supplemented with 10 g baker’s yeast displayed the highest growth. As conclusion, supplementation of baker’s yeast in fish food could enchance the growth of fish.   Keywords:  Oreochromis niloticus, immunostimulant, baker’s yeast, growth

The objective of this research was to evaluate the efficacy of Baker’s Yeast S. cereviciae in enhancing the resistance of nile tilapia (Oreochromis niloticus) to A. hydrophila. As many as 250 fish with an average weight of 28.78±2.44 g were obtained from Fish Culture Development and Training Center of Tateli. After acclimatization, the fish were fed pellet supplemented with Baker’s Yeast as treatments at five different doses, A=0 gr/kg feed, B=5 gr/kg feed, C=10 gr/kg feed, D=15 gr/kg feed, and E=20 gr/kg feed each of which was with three replications.  They were fed for four weeks at 5%/BW/day, twice a day at 08.00 and 16.00, respectively. After feeding period, the fish were challenged intraperitoneally with A. hydrophila.  Before injection, a pathogenicity test of bacteria A. hydrophila was conducted for LD50. Challenged test was carried out by injecting fish with 0.2 ml of bacterial suspension containing 5 x 106 cfu/ml. The fish resistance was observed for 14 days. Dead fish were taken out and bacterial isolation was performed to confirm the cause of the dead.  Results showed that supplementation of Baker’s Yeast into fish pellet had significant effect  on the fish resistance (p=0.00).  The highest resistance (66.6%) was recorded in fish fed with pellet supplement of 5 g Baker’s Yeast per kg of pellet while control fish was only 50%.  As conclusion, supplementation of Baker,s Yeast into fish pellet could enhance resistance of fish to the pathogen. Penelitian ini bertujuan untuk menguji efikasi ragi roti S. cereviciae dalam meningkatkan resistensi ikan nila (Oreochromis niloticus)terhadap bakteri patogen A. Hydrophila. Sebanyak 250 ekor ikan nila dengan berat awal rata-rata 28,78±2,44 g yang diambil dari Balai Pengembangan dan Pembinaan Pembudidayaan Ikan (BP3I) Tateli. Setelah aklimatisasi, ikan diberi ragi roti sebagai perlakuan dengan lima dosis berbeda dan masing-masing perlakuan memiliki tiga ulangan.Perlakuan ragi roti yang digunakan adalah A=0 gr/kg pakan, B=5 gr/kg pakan, C=10 gr/kg pakan, D=15 gr/kg pakan, E=20 gr/kg pakan. Lama pemberian pakan perlakuan empat minggu dengan dosis 5%/bb/hari dan diberikan 2 kali sehari yaitu Pukul 08.00 dan Pukul 16.00. Setelah diberikan ragi roti selama empat minggu ikan diuji tantang dengan bakteri A. Hidrophyla secara Intraperopeneal (ip). Sebelum penyuntikan, dilakukan uji patogenitas bakteri yang memberikan tingkat kematian 50% (LD50). Uji tantang dilakukan dengan cara menyuntikkan 0,2 ml suspensi bakteri pada kepadatan 5 x 106 cfu/ml (sesuai hasil uji patogenitas) pada rongga tubuh ikan. Pengamatan resistensi ikan akan dilakukan setiap hari selama 14 hari. Ikan mati dikeluarkan dan dilakukan isolasi bakteri untuk mengkonfirmasi penyebab kematian ikan. Hasil penelitian mendapatkan bahwa pemberian ragi roti berpengaruh sangat nyata (P=0,00) pada resistensi ikan terhadap bakteri A. Hydrophila. Resistensi tertinggi dicapai pada ikan yang diberi perlakuan B (5 g/kg pakan) dengan tingkat resistensi mencapai 66,6%. Sedangkan ikan yang tidak diberi perlakuan ragi roti (control) memiliki resistensi 50 %. Sebagai kesimpulan penambahan ragi roti dalam pakan dapat meningkakan resistensi ikan terhadap infeksi pathogen.

Motile Aeromonas Septicaemia

Motile Aeromonas Septicaemia disease (MAS) attacking tilapia has increased in recent years as a consequence of intensive aquaculture activities, which led to losses in aquaculture industry. The agent causing MAS disease is Aeromonas hydrophila. The disease can be controlled with the β-glucan. As immunostimulants, β-glucans can also increase resistance in farmed tilapia. Studies on the use of β-glucan extracted from baker's yeast Saccharomyces cerevisiae was intended to evaluate the non-specific immune system of tilapia that were challenged with Aeromonas hydrophila. The method used was an experimental method with a completely randomized design consisting of four treatments with three replicats. The dose of β-glucan used as treatments were 0 mg.kg-1 fish (Control), 5 mg.kg-1 fish (B), 10 mg.kg-1 fish (C) and 20 mg.kg-1 fish (D), each treatment as injected three times at intervals of 3 days, the injection volume of 0.5 ml/fish for nine days and resistance surveillance for seven days. The results showed that the difference in the amount of β-glucan and the frequency of the injected real influence on total leukocytes, phagocytic activity and resistance. Total leukocytes, phagocytic activity and resistance to treatment was best achieved by the administration of C a dose of  10 mg.kg-1 of the fish© Penyakit Motil Aeromonas Septicaemia (MAS) yang menyerang ikan nila mengalami peningkatan selama beberapa tahun terakhir sebagai konsekuensi dari kegiatan akuakultur intensif, yang menyebabkan kerugian dalam industri budidaya. Agen utama penyebab penyakit MAS adalah Aeromonas hydrophila. Untuk mengendalikan penyakit tersebut dapat dilakukan dengan pemberian β-glukan. Sebagai imunostimulan, β-glukan juga dapat  meningkatkan resistensi pada ikan nila yang dibudidayakan. Pengkajian mengenai pemanfaatan β-glukan yang diekstrak dari ragi roti Saccharomyces cerevisiae dimaksudkan untuk menguji sistem imun non spesifik ikan nila yang diuji tantang dengan bakteri Aeromonas hydrophila. Metode yang digunakan yaitu metode eksperimen dengan rancangan acak lengkap yang terdiri dari empat perlakuan dan tiga ulangan. Dosis β-glukan  yang digunakan sebagai perlakuan sebesar 0 mg.kg-1 ikan (Kontrol), 5 mg.kg-1 ikan (B), 10 mg.kg-1 ikan (C) dan 20 mg.kg-1 ikan (D), masing-masing perlakuan diinjeksi sebanyak 3 kali dengan interval waktu 3 hari selama 9 hari, volume injeksi 0,5 mL/ekor ikan dan pengamatan resistensi selama tujuh hari. Hasil penelitian menunjukkan perbedaan jumlah β-glukan dan frekuensi pemberian yang diinjeksikan memberikan pengaruh nyata terhadap total leukosit, aktivitas fagositosis dan resistensi. Total leukosit, aktivitas fagositosis dan resistensi terbaik dicapai pada perlakuan C dengan dosis 10 mg.kg-1 ikan©
