Abstract

Udang vaname (Litopennaeus vannamei) merupakan salah satu komoditas unggulan budidaya perairan di Indonesia. Penyakit udang merupakan salah satu tantangan yang dihadapi oleh pembudidaya. Salah satu penyakit yang menyerang udang adalah infectious myonecrosis (IMN). Tujuan penelitian ini adalah mengevaluasi sistem produksi budidaya udang vaname saat terjadi wabah infeksi infectious myonecrosis virus IMNV di Tambak Pinang Gading, Bakauheni, Lampung Selatan. Sebanyak 2 petak tambak udang digunakan sebagai petak pengamatan yaitu petak A7 (2700 m2) dan A8 (3700 m2) dengan padata tebar udang masing-masing 74 ekor/m2 dan 54 m2. Kegiatan budidaya udang dilakukan mulai dari persiapan hingga panen. Penelitian dilakukan dengan mengevaluasi kinerja produksi dan kelayakan usaha budidaya udang vaname. Hasil penelitian menunjukkan bahwa  budidaya udang pada kondisi baik, kelangsungan hidup udang dapat mencapai 94,75% dengan keuntungan Rp. 43.335.000/tahun dan kondisi tidak baik saat terserang IMNV mencapai 34,83% dengan kerugian Rp. 49.906.080/tahun. Oleh karena itu, dapat disimpulkan bahwa budidaya udang vaname memiliki peluang usaha yang baik namun juga memiliki resiko kerugian akibat penyakit seperti IMNV. Evaluasi standar operasional prosedur (SOP) dan peningkatan biosekutitas perlu dilakukan untuk menjaga agar produksi budidaya udang tetap baik dan berkelanjutan.

Abstract

Curcuma spp. is a phytobiotic with potential application in fish farming. This study aimed to evaluate the potential of Curcuma zedoaria, Curcuma aeruginosa and Curcuma mangga extracts in striped catfish infected with Aeromonas hydrophila. The study used a complete randomized design (CRD) consisting of six treatments: KN (negative control), KP (positive control, fish infected without treatment), PE (C. zedoaria extract 6.25 g kg-1), HE (C. aeruginosa extract 6.25 g kg-1), ME (C. mangga extract 6.25 g kg-1) and KE (combination of C. zedoaria extract 2.1 g kg-1 + C. aeruginosa extract 2.1 g kg-1 + C. mangga extract 2.1 g kg-1). A total of 360 striped catfish, 10 ± 0.5 cm were kept in 18 aquariums measuring 50 × 40 × 35 cm3 and fed the treatment for 30 days. The challenge test was conducted on day 31 by injecting A. hydrophila suspension (106 colony-forming units (CFU) mL-1) intramuscularly into fish. The results showed that the treatment administered were able to stimulate the expression of interleukin-1â, interferon-ã 2a, 2b genes, increase the number of red and white blood cells, hematocrit, hemoglobin, phagocytosis activity, respiratory burst, reduce the population of A. hydrophila in the intestine, and reduce tissue damage in striped catfish. Striped catfish treated with the extracts showed significantly higher survival rates (p<0.05) compared to the positive control group. The survival rates were: KN (100.00 %), KP (53.33%), PE (93.33 %), HE (91.67 %), ME (93.33 %), and KE (88.33 %). In conclusion, the treatment administered were able to enhance the immune response and resistance of striped catfish infected with A. hydrophila.

Abstract

Sediment serves as a site for the accumulation of aquaculture waste. Oxidation-Reduction Potential (ORP) is an index indicating anaerobic conditions. A combination of host, pathogen, and suboptimal environmental quality can lead to disease outbreaks. One such disease is Acute Hepatopancreatic Necrosis Disease (AHPND), caused by Vibrio parahaemolyticus. This study was aimed to analyse the impact of sediment drying on infectivity of V. parahaemolyticus growth and health status of Pacific whiteleg shrimp. The sediment ORP used at the initial study was -37 mV. The sediment was dried for 120 hours at a temperature of 40.75 ± 2.73 °C. A total of 15 shrimp/aquarium with an average body weight of 2.35±0.22 g/individual were reared in aquarium sized 20x25x30 cm3 containing dried and undried sediment for 120 hours, then contaminated with 105 CFU/mL V. parahaemolyticus through immersion from the start of rearing until 20 days later. The results showed that sediment drying was able to reduce bacterial abundance and increase ORP sediment. The longer duration of cultivation, the more the sediment ORP decreased. Sediment ORP decreased with increasing shrimp farming duration. The highest bacterial abundance in the sediment on thrid phase of study was observed in the positive control treatment on D+10 ((2.02±0.39)x104 CFU/g), then it decreased until the end. Meanwhile, bacterial abundance in water and hepatopancreas decreased until the end of the study. Survival rates, immune responses, and growth parameters of shrimp with sediment drying were higher than the positive control (p<0.05) but not significantly different from the negative control. The histopathology of shrimp hepatopancreas profile in the sediment drying treatment was better compared to the positive control.

Abstract

Budidaya udang vaname (Litopenaeus vannamei) pada kepadatan tinggi meningkatkan stres dan risiko infeksi bakteri, khususnya Vibrio parahaemolyticus. Teknologi bioflok (BFT) melalui penambahan karbon  organik dapat meningkatkan biomassa mikroba heterotrof yang memperbaiki respons imun dan menurunkan virulensi bakteri. Penelitian ini bertujuan menganalisis respons imun dan resistansi udang yang dipelihara dengan padat tebar berbeda dalam sistem bioflok terhadap infeksi V. parahaemolyticus. Udang (0,44±0,02 g) dipelihara selama 7 hari sebanyak 16 perlakuan hasil kombinasi sistem bioflok dan kontrol (tanpa bioflok) dengan kepadatan 4, 8, 12, dan 16 ekor L-¹, lalu diuji tantang melalui perendaman dengan dosis V. parahaemolyticus 10u CFU mL-¹ dimulai sejak awal perlakuan. Hasil menunjukkan bahwa sistem bioflok meningkatkan parameter imun udang, termasuk total hemocyte count (THC), aktivitas fagositik (AF), respiratory burst (RB), dan aktivitas phenoloxidase (PO) secara signifikan (P<0,05) dibandingkan kontrol. Kelimpahan V. parahaemolyticus di air dan tubuh udang perlakuan bioflok lebih rendah dan berbeda signifikan (P<0,05) dengan kontrol positif. Bioflok juga meningkatkan tingkat kelangsungan hidup, dengan nilai pada kepadatan 4 ekor L-¹ (83,33±5,77%), dan tetap lebih baik dibandingkan kontrol hingga kepadatan 16 ekor L-¹. Sistem bioflok terbukti efektif meningkatkan respons imun, menekan infeksi V. parahaemolyticus, dan mempertahankan kelangsungan hidup udang vaname pada kepadatan tinggi.

Abstract

This study was carried out to obtain Vibrio isolates able to function as biocontrol of vibriosis in shrimp hatchery. Thirty one Vibrio isolates were isolated from tiger shrimp larvae and hatchery environments, i.e. Labuan, Pangandaran, and Lampung, Indonesia. Pathogenic  V. harveyi MR5339 was obtained from Maros, South-Sulawesi and was made as a rifampicin resistant mutant (RFR) to screen for those 31 Vibrio isolates in in vitro assays and to allow us to monitor their presence in shrimp larvae and larval rearing water. Almost all Vibrio  isolates could inhibit the growth of pathogenic V. harveyi MR5339 RFR. SKT-b isolate from Skeletonema was the most effective to inhibit the growth of V. harveyi MR5339 Rf* and significantly reduced larval mortality in pathogen challenge assays. These prospective biocontrol bacteria, at concentration of 10" CFU/ml, did not show pathogenicity to shrimp larvae. SKT-b was Gram negative, short rod-shape, exhibited yellow colonies on TCBS and swarming on SWC-agar media, motile, utilized glucose and sucrose but not lactose: produced extra-cellular protease and amylase, but did not produce chitmase. Partial sequencing of 16S-rRNA gene SKT-b showed SKT-b similarity to Vibrio alginofyticus. Keywords: shrimp larvae / biocontrol bacteria / vibriosis.
