Abstract

Wabah penyakit white spot diseases (WSD) akibat infeksi white spot syndrome virus (WSSV) menyebabkan penurunan produksi udang global. Alternatif pencegahan infeksi WSSV dapat dilakukan melalui peningkatan respons imun udang dengan aplikasi madu sebagai prebiotik. Penelitian ini bertujuan untuk menguji efektivitas pemberian madu dalam meningkatkan respons imun dan resistansi udang vaname (Litopenaeus vannamei) terhadap infeksi WSSV. Penelitian ini terdiri atas lima perlakuan dan tiga ulangan yang meliputi perlakuan kontrol positif (tanpa pemberian madu dan diuji tantang dengan WSSV), kontrol negatif (tanpa pemberian madu dan tanpa uji tantang dengan WSSV), pemberian madu pada dosis 0,2%; 0,4%; dan 0,6%; serta diuji tantang dengan WSSV. Udang vaname berukuran 0,4 ± 0,11 g diberi pakan komersial dengan penambahan madu selama 10 minggu sebelum diuji tantang dengan WSSV, kemudian udang diuji tantang dengan WSSV dan diamati sintasan, serta parameter respons imunnya selama tujuh hari. Hasil penelitian menunjukkan bahwa parameter respons imun udang yang diberi perlakuan madu meliputi total haemocyte count (THC), aktivitas fagositik (AF), respiratory burst (RB), dan phenoloxidase (PO), baik sebelum maupun setelah uji tantang dengan WSSV lebih baik (P<0,05) dibanding kontrol. Pada akhir uji tantang, sintasan udang yang diberi perlakuan madu pada dosis 0,4% dan 0,6% masing-masing mencapai 66,67%; sedangkan pada perlakuan kontrol positif hanya mencapai 36,67%. Hal ini menunjukkan bahwa pemberian madu pada dosis 0,4% efektif meningkatkan respons imun dan resistansi udang vaname terhadap infeksi WSSV.White spot disease (WSD) outbreaks due to white spot syndrome virus (WSSV) infection cause the decline of the global shrimp production. The alternative prevention method against WSSV infection can be done by the improvement of immune responses through the application of honey as a prebiotic. This study aimed to evaluate the effectiveness of the administration of honey in improving immune responses and resistance of Pacific white shrimp (Litopenaeus vannamei) against WSSV infection. This study consisted of five treatments and triplicates including positive control (without the administration of honey and challenged by WSSV); negative control (without the administration of honey and without the challenge test with WSSV); the administration of honey at doses of 0.2%, 0.4%, and 0,6% and challenged by WSSV. Pacific white shrimp sized 0.4 ± 0.11 g were fed commercial feed with the addition of honey for 10 weeks before challenged by WSSV, then the shrimp were challenged by WSSV and were observed their survival and immune responses parameters for seven days. The results of the study showed that immune responses parameters of the shrimp treated by honey treatments including total haemocyte count (THC), phagocytic activity (PA), respiratory burst (RB), and phenoloxidase (PO), both before and after the challenge test with WSSV were better (P<0.05) compared to control. At the end of the challenge test, the survival of the shrimp treated with honey treatments at doses of 0.4% and 0.6% reached 66.67%, while that of positive control treatment only reached 36.67%. These results indicated that the administration of honey at a dose of 0.4% was effective to improve immune responses and resistance of Pacific white shrimp against WSSV infection.

Abstract

ABSTRACT White spot disease caused by White Spot Syndrome Virus (WSSV) is the most serious viral disease and has a major impact on the decline in production of white shrimp farm. Improving the immune response through the application of prebiotic, probiotic and synbiotic is expected to be one of the environmentally friendly alternatives to prevent the disease. This study aimed to evaluate the effect of administrating Baccillus sp. NP5 probiotic, honey prebiotic and a combination both (synbiotic) in enhancing immune response and resistence of white shrimp to WSSV infection. This study consisted of five treatments and three replications, namely positive control (feeding without probiotics, prebiotics, and synbiotics then challenged with WSSV), negative control (feeding without probiotics, prebiotics, synbiotics, then injected with PBS), pro (feeding with the addition of Bacillus sp. NP5 probiotics then challenged against WSSV), pre (feeding with the addition of honey prebiotics then challenged against WSSV), and sin (feeding with the addition of synbiotics then challenged against WSSV). White shrimp with an average weight of 1.8±0.06 gram/shrimp were reared at a density of 15 shrimps per aquarium (60 cm x 30 cm x 30 cm and water height of 20 cm) for eight weeks, then challenge against WSSV at lethal dose (LD50) dose as much as 0.1 ml per shrimp. The results showed that the immune response and resistence of white shrimp after treatments of probiotics, prebiotics, and synbiotics were better than those in controls with the optimal found in prebiotics treatment. Keywords: Bacillus sp. NP5, honey, immune response, white shrimp, WSSV ABSTRAK White spot disease yang disebabkan oleh infeksi white spot syndrome virus (WSSV) merupakan penyakit viral paling serius dan berdampak besar terhadap penurunan produksi budidaya udang vaname. Perbaikan respons imun melalui aplikasi probiotik, prebiotik dan sinbiotik dapat menjadi salah satu alternatif ramah lingkungan untuk pencegahan serangan penyakit tersebut. Penelitian ini bertujuan untuk mengevaluasi pengaruh pemberian probiotik Bacillus sp. NP5, prebiotik madu dan gabungan keduanya (sinbiotik) dalam meningkatkan respons imun dan resistansi udang vaname terhadap infeksi WSSV. Penelitian ini terdiri dari lima perlakuan dan tiga ulangan yaitu kontrol positif (pemberian pakan tanpa probiotik, prebiotik, dan sinbiotik kemudian diuji tantang dengan WSSV), kontrol negatif (pemberian pakan tanpa probiotik, prebiotik, dan sinbiotik kemudian diinjeksi PBS), pro (pemberian pakan dengan penambahan probiotik Bacillus sp. NP5 kemudian diuji tantang dengan WSSV), pre (pemberian pakan dengan penambahan prebiotik madu kemudian diuji tantang WSSV), dan sin (pemberian pakan dengan penambahan sinbiotik kemudian diuji tantang dengan WSSV). Udang vaname dengan bobot rata-rata 1.8±0.06 gram/ekor dipelihara dengan kepadatan 15 ekor per akuarium (60 cm x 30 cm x 30 cm) selama delapan minggu, kemudian diuji tantang dengan WSSV sebanyak 0.1 ml per ekor pada dosis LD50. Hasil penelitian menunjukkan bahwa respons imun dan resistansi udang vaname setelah pemberian probiotik, prebiotik dan sinbiotik lebih baik (P<0.05) dibandingkan kontrol dengan hasil optimal pada perlakuan prebiotik.

Abstract

Biofloc technology has been shown to have a positive impact on shrimp culture by controlling pathogenic Vibrio. This study aimed to analyze the effect of biofloc on the Vibrio composition in water and shrimp gut, as well as the growth performance and microvilli of Pacific white shrimp (Penaeus vannamei). Shrimp post-larvae measuring 0.66 ± 0.02 g were reared in a glass aquarium (working volume 22 L) of 6 units with a density of 150 shrimp m-3 for 28 days. The treatments included rearing in the biofloc system with C/N ratio 10, and without a biofloc system as a control. The results showed that Vibrio was highly prevalent in the control gut (4.13%) and biofloc water (3.77%), but only a few were found in the control water (0.16%) and biofloc-treated gut (0.11%). V. hepatarius (1.10%) and V. nereis (1.06%) were found to dominate the Vibrio bacterial community in the biofloc system maintenance media, while Vibrio sp. Hep-1b-8 (2.26%) and V. parahaemolyticus (0.80%) known as a pathogenic bacteria dominated the control shrimp gut. The biofloc system significantly increased the digestive enzyme activity, growth performance, and microvilli length in the shrimp gut. In conclusion, the application of a biofloc system in shrimp culture can affect the composition and abundance of bacterial communities in both the culture environment and the shrimp gut, and improve growth performance with higher digestive enzyme activity and longer microvilli in the gut. Keywords: biocontrol, biofloc, microbiota, shrimp, Vibrio ABSTRAK Teknologi bioflok menunjukkan dampak positif pada kegiatan budidaya udang vaname dengan mengendalikan bakteri patogen salah satunya Vibrio. Penelitian ini bertujuan untuk menganalisis efek bioflok terhadap komposisi Vibrio pada air dan usus udang, serta kinerja pertumbuhan dan mikrovili udang vaname (Penaeus vanamei). Udang post-larva berukuran 0.66 ± 0.02 g dipelihara pada akuarium kaca (volume air 22 L) sebanyak 6 unit dengan kepadatan 150 ekor m-3 selama 28 hari. Perlakuan meliputi pemeliharaan udang pada sistem bioflok dengan rasio C/N 10, dan tanpa sistem bioflok sebagai perlakuan kontrol. Hasil pengamatan menunjukkan kelimpahan Vibrio yang cukup tinggi pada usus perlakuan kontrol (4.13%) dan air perlakuan bioflok (3.77%), tetapi sangat sedikit ditemukan pada air perlakuan kontrol dan usus perlakuan bioflok. Selanjutnya, V. hepatarius (2.26%) dan V. nereis (1.06%) terdeteksi mendominasi komunitas bakteri Vibrio di media pemeliharaan pada sistem bioflok, sedangkan Vibrio sp. Hep-1b-8 (2.26%) dan V. parahaemolyticus (0.80%) mendominasi usus udang vaname pada perlakuan kontrol. Sistem bioflok juga mampu meningkatkan aktivitas enzim pencernaan, performa pertumbuhan, dan panjang mikrovili usus secara signifikan (P < 0.05). Kesimpulan dari penelitian ini adalah penerapan sistem bioflok pada budidaya udang vaname mampu memengaruhi komposisi dan kelimpahan komunitas bakteri Vibrio pada lingkungan budidaya maupun pada usus udang, serta meningkatkan performa pertumbuhan dengan aktivitas enzim pencernaan yang lebih baik dan mikrovilli usus yang lebih panjang.

Abstract

One of the common diseases affecting the Pacific white shrimp (Penaeus vannamei) culture is vibriosis, caused by infection with Vibrio species, including Vibrio parahaemolyticus. Certain strains of V. parahaemolyticus that carry the PirA and PirB toxins are responsible for causing acute hepatopancreatic necrosis disease (AHPND). This study aimed to assess the pathogenicity of V. parahaemolyticus in P. vannamei using bacterial isolates from different sources. A challenge test was conducted using P. vannamei with an average weight of 0.9±0.1 g, exposed to bacterial concentrations of 104 CFU/mL, as determined by lethal concentration 50% (LC50). The experiment followed a completely randomized design with three treatments and three replicates: a control group (K) of uninfected shrimp, shrimp infected with V. parahaemolyticus from Tasikmalaya, West Java (Vp-1), and shrimp infected with V. parahaemolyticus from Situbondo, East Java (Vp-2). Parameters observed included the confirmation of V. parahaemolyticus and AHPND via polymerase chain reaction (PCR), mortality rate, clinical symptoms, bacterial load, and immune response indicators, including total haemocyte count, phagocytic activity, respiratory burst, phenoloxidase activity, and histopathological examination of the hepatopancreas and intestines. Both Vp-1 and Vp-2 isolates were identified as V. parahaemolyticus AHPND strains, infecting shrimp with clinical signs such as pale hepatopancreas, empty intestines, and lethargic movement. Tissue damage, including extensive necrosis in the hepatopancreas and intestines, was observed, leading to mortality rates of 73.33-81.67% with an average time to death ranging from 24.28 to 65.44 hours postinfection.

Abstract

Vibrio parahaemolyticus strain that produces PirA and PirB toxins is the main causative agent of Acute Hepatopancreatic Necrosis Disease (AHPND) in vannamei shrimp. This study aimed to evaluate the effect of biofloc application, probiotic Pseudoalteromonas piscicida 1Ub, and their combination on growth, immune response and resistance of vannamei shrimp infected with V. parahaemolyticus strain. This study used a completely randomized design consisting of biofloc-based system treatment with or without probiotic 1Ub and normal seawater as control. All treatment groups were challenged with V. parahaemolyticus AHPND strain at a cell density of 105 CFU mL”1 through immersion, while the negative control was reared without being pathogenic challenged. The shrimp used were in averaged body weight of 1.3 ± 0.002 g, reared for 21 days and fed five times a day at 06:00, 10:00, 14:00, 18:00, and 22:00 WIB. The results showed that the B+Pro combination challenge test treatment resulted the best growth performance (specific growth rate, absolute length gain and feed conversion ratio) (P<0.05) compared to other challenge test treatments. hrimp treated with B+Pro also showed a lower intestinal cell population of V. parahaemolyticus RfR, and significantly higher immune response values (P<0.05) than those of other challenge test treatments and K+. Furthermore, those parameters supported positive impact on final shrimp survival rates in the experiment. This study shows that the application of combination of biofloc and 1Ub probiotic bacteria can significantly protect and increase the resistance of vannamei shrimp to V. parahaemolyticus AHPND infection.
