Abstract

This research was conducted to study the effect of probiotic bacteria application through artificial feed on growth performance of tiger shrimp. The research was carried out for 42 days with four treatments and three replications, those were control, SKT-b (feed + SKT-b probiotic), 1 UB (feed + 1 UB probiotic) and commercial (feed + commercial probiotic). Feed and probiotic bacteria were mixed in ratio of 3:1 (weight : volume) by adding 3 % of white egg as a binder.  Then the test feed was analyzed by proximate analyses and compared by using control feed. Tiger shrimps with initial weight of 0.04 ± 0.005 g were reared in 50 cm x 40 cm  x 40 cm aquaria at the density of 15 shrimps per aquarium.  Feeding was carried out four times a day at 08.00, 12.00, 16.00, and 22.00. The weight of tiger shrimp were observed once every 2 weeks, whereas the water quality and the total abundance of bacteria in media were monitored at the beginning, middle and end of the research.The result showed that theadministration of the probiotic bacteria through artificial feed produced better growth rate than control. Application of 1 UB probiotic gave the best results by producing 9.03% growth rate and 1.35feed conversion ratio. Whereas, survival rates for all treatments were not significantly different from the range of values between 91.11% - 97.78%.Keywords: probiotic bacteria, feed, tiger shrimp

Abstract

In this study, fish feed supplemented by probiotic, prebiotic and synbiotic were applied to enhance the immune response and survival rate of the fish against Streptococcus agalactiae infection. Treatments used in this study, were as follows: feed containing 1% (v/v) of probiotic (C), feed containing 2% (v/v) of prebiotic (D) and feed containing mixed of 1% (v/v) of probiotic + 2% (v/v) of prebiotic (E, defined as synbiotic). Control fish (both positive, A; and negative, B; treatments) were fed by fish feed without containing neither probiotic nor prebiotic. In this study, test fish used monosex (all male) red tilapia with the average of body weight of 13,43±2,97 gram. The fish were fed by supplemented feed within first 30 days pre injection. After that, the treated fish were challenged by 109 CFU/ml of S. agalactiae. Nile tilapia fed by synbiotic (treatment E) had higher immune response (haemoglobin, neutrofil, and phagocyte indices) than control, but were not significantly different than those of treatment C, and D. After challenged test by S. agalactiae, treatment C, D and E resulted significantly higher resistance than that of control. The survival rate of fish fed by supplemented feed containing probiotic (C), prebiotic (D) and synbiotic (E) were 76%, 76% and 80%, respectively; higher than than positive control (50%). The results showed that addition of probiotic, prebiotic and synbiotic in fish feed could increase immune response and survival rate against S. agalactiae.Keywords : tilapia, probiotic, prebiotic, synbiotic, Streptococcus agalactiae

Abstract

Synbiotic application shows better results compared to the single use of probiotics or prebiotics. SKT-b bacteria have been shown to act as probiotics for aquatic animals, as well as sweet potatoes that are known to act as prebiotics. This study aims to examine the synbiotic potential of SKT-b probiotic bacteria and oligosaccharide extract from sweet potato in improving the growth performance of vaname shrimp. Shrimp were treated with synbiotic feed with different prebiotic concentrations of 1% (Pro + Pre 1%), 2% (Pro + Pre 2%) and 3% (Pro + Pre 3%). The treated food was given to shrimp (weight ± 1.9 g) for 30 days. Oligosaccharides extracted from sweet potato can act as a prebiotic which increases the bacterial population in vaname shrimp’s intestine. The application of synbiotics can improve the growth performance of vaname shrimp including the addition of body weight, feed efficiency, digestive enzyme activity, protein retention and body fat of shrimp. The treatment of Pro + Pre 2% and Pro + Pre 3% shows better growth performance of vaname shrimp.

Abstract

ABSTRACTThe culture of vaname shrimp can not be separated from various outbreaks of diseases, especially by viral infections including Infectious Myonecrosis (IMN) which has caused the cumulative death of vaname shrimp up to 70%. One effort to prevent diseases in shrimp is by applying synbiotics. This study aims to evaluate the synergistic effects of probiotic bacteria SKT-b and oligosaccharides extracted from sweet potatoes, in increasing resistance to IMN disease. Shrimp are treated with synbiotic feed with different prebiotic concentrations of 1% (Pro + Pre 1%), 2% (Pro + Pre 2%) and 3% (Pro + Pre 3%). Feed treatment was given to the shrimp (weight ± 1.9 g) for 30 days. Then the shrimp were infected with the IMN virus and carried out observations for 10 days including survival parameters, clinical symptoms, total hemocytes and phenoloxidase activity. Application of synbiotic can increase vaname shrimp resistance to IMN virus infection. This increase is indicated by the increase in survival of shrimp and the decrease in the rate of infection from IMN, observed through clinical symptoms. One of the improvements in shrimp immune response was due to an increase in total leukocytes and phenoloxidase activity. In general, the treatment of Pro + Pre 2% and Pro + Pre 3% showed a better response to the increase in resistance of vaname shrimp compared to other treatments. ABSTRAKBudidaya udang vaname tidak lepas dari berbagai wabah penyakit yang menyerang, terutama oleh infeksi virus diantaranya Infectious Myonecrosis (IMN) yang telah menyebabkan kematian kumulatif udang vaname hingga 70%. Salah satu upaya pencegahan penyakit pada udang adalah dengan aplikasi sinbiotik. Penelitian in bertujuan untuk mengevaluasi efek sinergis dari bakteri probiotik SKT-b dan oligosakarida hasil ekstraksi dari ubi jalar, dalam meningkatkan resistensi terhadap penyakit IMN. Udang diberi perlakuan pakan sinbiotik dengan konsentrasi prebiotik berbeda yaitu 1% (Pro+Pre 1%), 2% (Pro+Pre 2%) dan 3% (Pro+Pre 3%). Pakan perlakuan diberikan ke udang uji (bobot ± 1.9 g) selama 30 hari. Selanjutnya udang uji diinfeksi dengan virus IMN dan dilakukan pengamatan selama 10 hari meliputi parameter sintasan, gejala klinis, total hemosit dan aktifitas phenoloksidase. Aplikasi pemberian sinbiotik mampu meningkatkan resistensi udang vaname terhadap infeksi virus IMN. Peningkatan resistensi ini ditandai dengan meningkatnya sintasan udang dan menurunnya tingkat infeksi dari IMN yang diamati melalui gejala klinis. Peningkatan respon imun udang salah satunya dikarenakan peningkatan total leukosit dan aktivitas phenoloksidase. Secara umum, perlakuan Pro+Pre 2% dan Pro+Pre 3% menunjukkan respon yang lebih baik terhadap peningkatan resistensi udang vaname dibandingkan dengan perlakuan lainnya.

Abstract

One of the diseases that often attack the catfish is motile aeromonas septicemia (MAS) caused by Aeromonas hydrophila. This study aimed to evaluate the immune responses and growth performance of catfish that cultivated on biofloc systems with different carbon sources and infected by A. hydrophila. This study was conducted over 30 days, consists of five treatments with three replications viz., providing molasses carbon source (A), tapioca flour (B), wheat flour (C), positive control (D) and a negative control (E). The results showed that the immune response such as total erythrocytes, hematocrit, hemoglobin concentration, total leukocyte, phagocytic activity, and respiratory burts activity at molasses (A), tapioca flour (B),and wheat flour (C) treatment showed better results than the control. Carbon sources from molasses, tapioca and wheat were able to increase total bacteria and decrease the growth of A. hydrophila in the waters as well as in catfish organs. Catfish growth performance in biofloc system with tapioca flour carbon source provide daily growth rate which was higher and significantly different (p <0.05) than control. While the biofloc system with molasses, tapioca and wheat carbon source could decrease feed conversion ratio and increase the retention of the protein. Retention of lipid in the biofloc system with molasses carbon source showed the highest results. The addition of molasses, tapioca and wheat as carbon sources into bioflock system could reduce the abundance of A. hydrophila, while immune response and growth performance of catfish increase well. Abstrak Salah satu penyakit yang sering menyerang ikan lele adalah Motil Aeromonad Septicemia yang disebabkan oleh bakteri Aeromonas hydrophila. Penelitian ini bertujuan untuk mengevaluasi respon imun dan kinerja pertumbuhan ikan lele yang dibudidayakan pada sistem bioflok dengan sumber karbon yang berbeda serta diinfeksi oleh A. hydrophila. Peneli- tian dilakukan selama 30 hari, menggunakan rancangan acak lengkap yang terdiri atas lima perlakuan dengan tiga ulangan yaitu penambahan sumber karbon molase (A), tepung tapioka (B), tepung terigu (C), kontrol positif (D), dan kontrol negatif (E). Hasil penelitian menunjukkan bahwa respon imun seperti total eritrosit, hematokrit, kadar hemoglo- bin, jumlah leukosit, aktivitas fagositosis, dan ledakan pernapasan pada perlakuan molase (A), tepung tapioka (B), dan tepung terigu (C) menunjukkan hasil yang lebih baik daripada kontrol. Sumber karbon molase, tapioka, dan terigu mampu meningkatkan total bakteri dan menekan pertumbuhan A. hydrophila di air dan organ ikan lele. Kinerja pertum- buhan ikan lele di sistem bioflok dengan sumber karbon tepung tapioka memberikan laju pertumbuhan harian yang le- bih tinggi dan berbeda nyata (P <0,05) dibandingkan kontrol. Sistem bioflok dengan sumber karbon molase, tapioka, dan terigu dapat menurunkan nisbah konversi pakan dan meningkatkan retensi protein. Retensi lemak dalam sistem bio- flok dengan sumber karbon molase menunjukkan hasil tertinggi. Penambahan sumber karbon molase, tapioka, dan teri- gu dalam sistem bioflok dapat menurunkan kelimpahan A. hydrophila dan meningkatkan respon imun dan kinerja per- tumbuhan ikan lele.

Abstract

Intensive aquaculture system decreases water quality through the increment of metabolic waste products such as organic nitrogen. The biofloc technology is an alternative solution to avoid the impact of high nutrients disposal in aquaculture production system. This study aimed to evaluate the impacts of biofloc technology using different carbon sources on the production performance of juvenile striped catfish, Pangasianodon hypophthalmus. Completely randomized design with 4 treatments (3 replications) was used in this research i.e.: (A) molasses carbon source, (B) tapioca carbon source, (C) wheat carbon source, and (D) without additional carbon. The juveniles length 2.26±0.12 cm, initial average body weight 0.17±0.05 g were reared for 30 days. Twelve glass tanks (60 cm x 30 cm x 40 cm) filled with 36 L freshwater were used as the experimental culture units. The fish were fed three times daily with a commercial feed containing 27% of crude protein. External organic carbon was added daily two hours after feeding at C/N 15 estimated ratio. The observed parameters i.e.: floc profile, the nutritional content of biofloc, water quality, survival rate, final body length, daily growth rate, feed conversion ratio, protein retention, and lipid retention. The best results showed by molasses treatment, the highest fish survival rate (97.41±0.16 %), longest standard length (2.84±0.1 cm) and decreased feed conversion ratio (0.36±0.04).
