Salah satu penyakit yang sering menyerang udang di pembenihan adalah vibriosis, yang disebabkan oleh bakteri Vibrio harveyi. Penelitian bertujuan untuk mengetahui tingkat ketahanan beberapa strain larva udang galah, yaitu asal Sungai Ogan, Sumatera Selatan; Sungai Asahan, Sumatera Utara; Sungai Barito, Kalimantan Selatan; Sungai Ciasem, Jawa Barat; dan strain GIMacro terhadap infeksi bakteri Vibrio harveyi, sebagai dasar perakitan varietas unggul udang galah. Penelitian dilakukan dengan Rancangan Acak Lengkap (RAL) dengan lima perlakuan, yaitu strain larva dan tiga ulangan. Larva udang galah stadia 4 dari 5 populasi berbeda, dengan panjang rata-rata 2,7±0,4 mm ditempatkan di stoples volume 3 L dengan padat penebaran larva 100 ekor/L. Setiap wadah diisi 1 L air payau 10‰. Selanjutnya diinfeksi bakteri V. harveyi patogen berumur 24 jam dengan kepadatan 105 cfu/mL. Nauplii Artemia diberikan pada pagi dan sore hari. Parameter yang diamati meliputi pengamatan visual abnormalitas larva uji yang dilihat dari tingkah laku larva dan kondisi organ hepatopankreas, tingkat sintasan, kelimpahan total bakteri Vibrio sp. dan V. harveyi, identifikasi bakteri, dan parameter kualitas air. Selama 48 jam perlakuan sintasan larva yang berasal dari strain induk yang berbeda memberikan hasil berbeda nyata dengan tingkat sintasan tertinggi pada larva asal Barito, yaitu 75%; diikuti GIMacro 65%; Asahan 61,33%; Ciasem 53,66%; strain Ogan 20%.Vibriosis caused by Vibrio harveyi is a serious problem in intensive system hatcheries of freshwater prawn. This study was conducted to study the resistance of larvae from different locations i.e. Ogan River, South Sumatra; Asahan River, North Sumatra; Barito River, South Kalimantan; Ciasem River, West Java; and GIMacro, as part of breeding program to create superior prawn strain. Complete randomized design was used in this study, with 5 treatments, i.e. larvae source and 3 replications. 4th stage of freshwater prawn larvae from the different populations, average total length of 2,7±0,4 mm, were reared in 3 liters buckets with larvae density of 100 larvae/L. Each bucket was filled with 1 L of 10‰ saline water. V. harveyi aged 24 hours was inoculated in each bucket with a density of 105 cfu/mL. Artemia sp. nauplii was given to the larvae twice per day. Some parameters consisting of abnormalitas of larvae, larvae behaviour, hepatopancreas performance, mortality, total of Vibrio sp. number and water quality was observed during the study. During 48 hours of the treatment, showed that factor of different larvae location gave a significant result to larvae survival rate. The highest survival rates was observed in the Barito larvae population (75%), followed by GIMacro (65%), Asahan (61.33%), Ciasem (53.66%), and Ogan 20%.

Kandungan bahan bioaktif pada tanaman memiliki beragam potensi aktivitas biologis dan dimanfaatkan dalam budidaya ikan sebagai alternatif untuk pencegahan dan pengobatan penyakit ikan. Serapoh (Chromolaena odorata) diketahui memiliki bahan bioaktif namun penerapan untuk pencegahan dan pengobatan penyakit pada kakap putih belum pernah diteliti. Penelitian ini bertujuan untuk mengevaluasi potensi antioksidan dan antibakteri daun serapoh secara in vitro terhadap Vibrio harveyi penyebab penyakit black body syndrome pada benih kakap putih. Penelitian secara in vitro melingkupi analisis fitokimia, uji antioksidan dan antibakteri. Hasil uji menunjukkan bahwa ekstrak daun serapoh mengandung flavonoid, tannin, saponin, dan steroid. Rendemen dari hasil maserasi dengan pelarut akuades, etanol, etil asetat, dan n-heksan berturut-turut adalah 11,34%; 9,13%; 4,21%; dan 1,48%. Ekstrak etil asetat memiliki kandungan total fenol yang tertinggi (212,8 mg/g) dibanding ekstrak yang lain. Kandungan total flavonoid yang tertinggi terdapat pada ekstrak etanol (195,5 mg/g) diikuti dengan ekstrak etil asetat (20,2 mg/g), n-heksan (10,6 mg/g), dan akuades (8,1 mg/g). Nilai potensi antioksidan ekstrak etanol lebih tinggi (86,59%) dibanding ekstrak yang lain namun potensi antioksidan ekstrak etanol, etil asetat, dan akuades tidak berbeda nyata dengan asam askorbat sebagai pembanding. Ekstrak etanol, etil asetat, dan n-heksan dapat menghambat pertumbuhan V. harveyi. Ekstrak etanol bersifat bakteriostatik (1,25 mg/mL) dan bakterisidal (5 mg/mL), serta menyebabkan kerusakan sel sehingga metabolit seluler seperti asam nukleat dan protein dapat keluar dari sel. Hasil penelitian menunjukkan bahwa ekstrak daun serapoh memiliki potensi antioksidan dan antibakteri terhadap V. harveyi sehingga dapat digunakan untuk pencegahan dan pengobatan penyakit black body syndrome pada benih kakap putih.Bioactive compounds in plants have various potential biological activities and are commonly used in fish farming as alternatives to prevent and treat fish diseases. Serapoh (Chromolaena odorata) is known to have bioactive compounds, yet its application to prevent disease in Asian seabass has not been studied. This study aimed to evaluate the antioxidant and antibacterial potential of serapoh leaves in vitro against Vibrio harveyi, causing black body syndrome disease in Asian seabass. The performed tests in this study consisted of phytochemical analysis, antioxidant, and antibacterial tests. The results showed that serapoh leaf extract contains flavonoids, tannins, saponins, and steroids. The yields obtained from maceration with aquadest, ethanol, ethyl acetate, and n-hexane solvents were 11.34%; 9.13%; 4.21%; and 1.48%, respectively. Ethyl acetate extract had the highest total phenol content (212.8 mg/g) compared to the other extracts. Ethanol extract has the highest total flavonoid content (195.5 mg/g) followed by ethyl acetate (20.2 mg/g), n-hexane (10.6 mg/g), and aquadest (8.1 mg/g). The highest antioxidant potential value was shown by ethanol extract (85.59%), but the antioxidant potentials of ethanol, ethyl acetate, and aquadest extracts were not significantly different from ascorbic acid. Ethanol, ethyl acetate, and n-hexane extracts can inhibit the growth of V. harveyi. Ethanol extract has bacteriostatic (1.25 mg/mL) and bactericidal (5 mg/mL) properties. The exposure of V. harveyi to ethanol extract resulted in cellular damage that can release cellular metabolites such as nucleic acids and proteins. In conclusion, serapoh leaf extract had antioxidant and antibacterial potential against V. harveyi and could be used to prevent or treat black body syndrome in Asian seabass.

Highlight Research Cinnamaldehyde for shrimp Dynamics of Vibrio and the correlation with shrimp health status Green and yellow Vibrio bacteria in water, intestine, and hepatopancreas of shrimp Cinnamaldehyde decrease the number of green Vibrio bacteria Abstract Disease can cause shrimp mortality and high economic losses caused by Vibriosis group. One alternative is using cinnamaldehyde which function as an anti-microbial and inhibit the production of toxins released by microorganisms. This study aimed to evaluate the administration of cinnamaldehyde on the dynamics of Vibrio bacteria and the health status of Pacific white shrimp fed with cinnamaldehyde-containing feed. This study used a completely randomized design (CRD) consisted of 4 treatments and 3 replications consisting of treatment K, A, B, and C which mean feeding without cinnamaldehyde, feeding containing cinnamaldehyde dose of 0.05%, 0.1%, and 0.2% respectively. Parameters included total bacteria (green and yellow Vibrio) in water, intestine, and hepatopancreas, as well as immune responses parameters, including total hemocyte count (THC), respiratory burst (RB), and phenol-oxidase (PO). All data were tabulated in Microsoft Excel 2016 and all statistical analysis was conducted in the SPSS v.22.0 software with one-way ANOVA followed by Duncan Multiple Range Test (DMRT (P=0.05). The results showed that the administration of cinnamaldehyde influences the dynamics of Vibrio and health status of shrimp. At the beginning and at the end of cinnamaldehyde administration, green and yellow Vibrio bacteria are mostly found in water, intestine, and hepatopancreas. The administration of cinnamaldehyde to Pacific white shrimp can reduce the number of green Vibrio bacteria both in the intestine and hepatopancreas as shown in treatments C and B. Cinnamaldehyde also affected the higher percentage of yellow Vibrio bacteria in treatments C and B compared to control (K). The highest immune responses of THC and RB were produced in treatments A and C compared to K. The decrease of green Vibrio bacteria and increased colonization of yellow Vibrio bacteria were correlated with immune responses. The best treatment in this study is treatment C.

Vibrio parahaemolyticus is one of the pathogens in crustaceans that can cause mass death in vannamei shrimp farming. This study aimed to evaluate the effect of administering the commercial herbal supplement Phycurma Aquatic (PA) through feeding at different doses to prevent V. parahaemolyticus infection in vannamei shrimp. This study used a completely randomized design (CRD) consisting of five treatments and three replications, which are negative control group, positive control group, and PA at doses of 2.5, 5.0, and 7.5 mL kg-1 feed. Shrimps were reared for 30 days and fed five times a day. On the 31th day, shrimps were challenged with V. parahaemolyticus at a dose of 105 CFU mL-1, except for the negative control group. The results showed that the administration of 5.0 mL kg-1 of PA in the feed gave the best growth performance (P<0.05) compared to other treatments. The administration of 5.0 mL kg-1 PA in feed also enhanced shrimp health status and significantly increased the total hemocyte count, phagocytic activity, respiratory burst, and phenoloxidase. Furthermore, the administration of PA also increased antioxidant activity, reduced malondialdehyde levels, decreased V. parahaemolyticus population in the intestine, and reduced hepatopancreas tissue damage. Moreover, the survival rate of vannamei shrimp before and after the challenge test in the treatment group with a dose of 5.0 mL kg-1 of PA was significantly higher (P<0.05) compared to other treatments.
