Pengaruh Pemberian Probiotik Lactobacillus brevis dan Prebiotik Oligosakarida terhadap Respon Imun dan Resistensi Benih Patin Siam (Pangasionodon hypophthalmus) Yang Diinfeksi Aeromonas hydrophila
No full textThai catfish (Pangasianodon hypophthalmus) is one of the important economic and cultivated fish species in Indonesia. while diseases caused by Aeromonas hydrophila often breakout and spread in catfish farming and sometimes cause large economic losses. Aeromonas hydrophila is a causative agent of motile aeromonad septicemia (MAS). The wide and frequent use of antibiotics in aquaculture for this diseases, has resulted in the development and spread of antibiotic resistance. The other alternative for this case were probiotics, prebiotics, and combined of probiotics and prebiotics (synbiotics). Probiotics are live microbial supplements that beneficially affect the host animal by improving its microbial balance. These strains commonly used as probiotics were Lactobacillus. Prebiotics are non-digestible food ingredients that stimulate the growth with selective of intestinal microbial like bifidogenic and lactic acidbacteria in the gastro-intestinal tract. Typically, the prebiotics consist of oligosaccharides, like fructooligosaccharide (FOS), dan galactooligosaccharide (GOS).The aim of this study was to evaluate of probiotic Lactobacillus brevis, prebiotic Oligosaccharides and synbiotics upon the population bacteria in the intestine, immune response, survival (SR), and growth rate (SGR) of Thai Catfish seeds (Pangasionodon hypophthalmus) which was infected by Aeromonas hydrophila. The study was carried out at the Fish Health Laboratory, Aquaculture Department of the Faculty of Fisheries and Marine Science Bogor Agricultural University; College of Fisheries university Extension Programe; and Main Centre of Freshwater Aquaculture Development, on October – December 2012. The parameters were total number of Lactobacillus sp. in the gut, total number of erythrocyte, hemoglobin, hematocrit, leucocyte, differntial leucocyte, and phagocytic activity, survival rate, growth rate, FCR (feed convertion ratio), and water quality. For in vivo test 5 (five) treatments and three replicated utilized, i.e. positive control (K(+)), negative control (K(-)), probiotic (Pro), prebiotics Oligosaccharides (Pre) and sinbiotics (Sin). One-way ANOVA was used to determine differences among the treatments. When a significant (p<0.05) difference was detected, the means were compared by use of Duncan’s multiple range test, and analysed by Xl-stat programe The results of the characteristics test showed that the species of probiotic and pathogen were Lactobacillus brevis and Aeromonas hydrophila respectively. In vivo test was carried out in 5 (five) treatments, i.e. positive control (K(+)), negative control (K(-)), probiotic (Pro), prebiotic (Pre) and synbiotic (Sin). The results showed that the total number of Lactobacillus sp. in the gut were between vi 101-106 (CFU/gr) and the total number of erythrocyte, hemoglobin, hematocrit, leucocyte, differntial leucocyte, and phagocytic activity have shown significant different (p<0.05) with control at the some times. The treatments of Sin, Pre, Pro and K(-) were at 100% in survival rate (SR), while K(+) was (43.33 ± 11.55)%. The growth rate showed significant different (p<0.05), with the highest value was on Sin treatment (3,37 ± 0.14)%. The FCR of Pro, Pre, and Sin were 1,414±0,13; 1,431±0,08 and 1,305±0,08. This fact suggested that Sin was better than the other treatments in immune respon at total erythrocyte, hemoglobin, hematocrit, and total leucocyte
EKTOPARASIT DALAM PERSPEKTIF PERIKANAN BUDIDAYA
Get PDFPengembangan sektor perikanan budidaya di Indonesia harus terus dilakukan mengingat hampir 70% produksi ikan berasal dari sektor ini. Dalam pengembangannya, salah satu faktor yang harus diperhatikan adalah masalah kesehatan ikan, terutama yang berhubungan dengan hama dan penyakit termasuk di dalamnya ektoparasit. Meskipun tidak mematikan ikan secara langsung, ektoparasit sangat berbahaya bagi ikan karena menjadi pintu pembuka masuknya patogen yang berbahaya bagi kehidupan ikan, baik dari jenis virus, bakteri, jamur maupun dari jenis endoparasit. Identifikasi jenis dan keberadaan ektoparasit merupakan upaya awal untuk penanggulangan maupun antisipasi agar tidak terjadi wabah ketika gejala awal sudah diketahui. Upaya lain adalah penanggulangan ketika parasit ini telah menginfeksi yang kegiatannya dapat dilakukan melalui penggunakan bahan kimia, fitokimia, fitofarmaka, maupun dengan manipulasi lingkungan dan pakan.In Indonesia, 70 percent of fish production is contributed by aquaculture activities. It is therefore necessary to prioritize this activity to sustain the share of fish and fisheries activities to Indonesian economy. Keeping the fish always in healthy condition and prevention them from diseases and parasites such as ectoparasite are important factors in aquaculture. Ectoparasite not only indirectly causing fish loss but they are also very dangerous in opening the invasion of fish pathogens (viruses, bacteria, fungi, or endoparasites). It is then necessary to identify ectoparasite as soon as early symptoms are detected so that further negative impacts could be avoided. When the parasites have already attacked, a couple of treatment could be implemented: chemical poisons, phytochemicals or other natural agents, and also applying environment and feed manipulations

EFFECTS OF FEED REDUCTION ON GROWTH PERFORMANCE, WATER QUALITY, AND HEMATOLOGY STATUS OF AFRICAN CATFISH, Clarias gariepinus REARED IN BIOFLOC POND SYSTEM
Get PDFBiofloc technique is a method of fish culture using minimal water exchange and microbial aggregates formed within the culture media as fish supplementary feed. Biofloc as a protein source is currently not being considered part of the feeding dosage in catfish culture. This present work aimed to determine the effects of commercial feed reduction on growth performance, water quality, and hematology of catfish cultured in biofloc ponds. Fish with an average body weight of 7.53 ± 0.47 g were stocked in nine ponds with a stocking density of 100 fish/pond and reared for nine weeks. The experiment was arranged in a completely randomized design, with the following treatments: full feed + non-biofloc (C100) as control; 10% less feed + biofloc (B90); 20% less feed + biofloc (B80). As such, the total feed doses given daily per each treatment fish biomass were: 5% for C100, 4.5% for B90, and 4.0% for B80. Each treatment was arranged in triplicates. The results showed that all water quality parameters (dissolved oxygen, pH, TAN, and nitrite) and biofloc concentrations did not differ significantly among the treatments (P>0.05). Specific growth rate, survival rate, weight gain, and feed conversion ratio of the fish were also not significantly different (P>0.05). The weight gain of biofloc-treated fish in B90 and B80 reached 2.71% and 12.65%, respectively; which were higher than the control treatment during the treatment period. The feed conversion ratios of B90 and B80 were 14.39% and 7.58%, respectively; lower than the control treatment. The biofloc treatment did not adversely alter the fish’s blood cell profiles. This study revealed that feed reduction did not affect water quality in the ponds and blood cell profiles of the fish. Moreover, fish in the biofloc-treated ponds had higher weight gain and lower food conversion ratios compared to fish cultured in the non-treated biofloc ponds. This study suggests that using the biofloc system in catfish rearing can reduce the use of feed up to 10%-20% with similar biomass yield compared to the non-biofloc system
