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©

Abstract Dissolved oxygen is the parameters key of water quality. Low level of dissolved oxygen can affect the function and slow growth, can even cause death to fish in hypoxia condition. The aims of this experiment were to determine the effect of population density of Daphnia spp. of dissolved oxygen concentration and the correlation between dissolved oxygen concentration with color scoring of Daphnia spp. This method was experimental with Completely Randomized Design as experiment design with 6 treatments and 4 replications. The treatment that was given were the differences of Daphnia spp. density that consisted of treatment A (50 individu/200 ml), treatment B (250 individu/200 ml), treatment C (450 individu/200 ml), treatment D (650 individu/200 ml), treatment E (850 individu/200 ml), and treatment F (1050 individu/200 ml). The results showed that the difference of Daphnia spp. density showed highly significant effect of dissolved oxygen concentration of treatment medium (p<0,01). In addition, this experiment also showed that the dissolved oxygen concentration in treatment medium showed negative correlation with color score of Daphnia spp.

The effect of baker’s yeast as immunostimulant on innate immunity of carp (Cyprinus carpio L) had been investigated.  Fish was gathered from Freshwater Aquaculture Board (BBAT) Tatelu, Province of North Sulawesi.  The fish were acclimatized for a week in 15 aquariua with a density of 25 fish/aquarium. After acclimatization the fish were fed pellet supplemented with baker’s yeast as immunostimulant at 0, 5, 10, 15 and 20 g / kg of feed for four weeks as much as 5%/body weight of fish/day with the frequency of feeding twice a day at 08.00 am and 16.00 pm . This study used Completely Randomized Design (RAL) with five treatments and each treatment had three replications. Immune parameters consisting of total leucocytes and phagocytosis activity were measured in the last week. After  four weeks of feeding, the total leukocytes from the carp fed with the addition of baker’s yeast 10 g / kg of feed were significantly increased compared with the fish not being fed with the addition of bread yeast (p <0.01). Phagocytic activity of phagocyte cells from carp also increased significantly in fish fed pellet with the addition of 5 g of baker’s yeast / kg of feed (p = 0.01). In conclusion, the addition of baker’s yeast as immunostimulant in the diet at 5-10 g/kg of pellet can increase the nonspecific immune response of carp. Keywords:  baker’s yeast, carp, nonspesific immune response, total leucocytes, phagocytosis activity
