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

Graphical Abstract   Highlight Research 1. A lytic bacteriophage was successfully isolated from catfish pond water in Dramaga, Bogor, with a high density of 5.68 × 10⁹ PFU/mL. 2. Characterization revealed round to irregular plaque morphology with high clarity and diameters reaching 0.35 cm. 3. The bacteriophage exhibited high host specificity, being effective only against the A. hydrophila AH03 isolate from the AAHL collection. 4. Treatment at MOI 10 resulted in more effective inhibition of A. hydrophila growth compared to other treatments.   Abstract Aquaculture plays a vital role in global protein supply, yet its increasing production faces disease-related challenges, particularly A. hydrophila infections. This pathogen causes Motile Aeromonas Septicemia (MAS), leading to mass mortality in catfish and significant economic losses. While antibiotics have been the primary solution, their use is now restricted due to antimicrobial resistance, necessitating safe and sustainable alternatives. Phage have emerged as environmentally friendly, specific biocontrol agents to combat such infections. This study aimed to evaluate the effectiveness of lytic phage in controlling the fish pathogen A. hydrophila through an in vitro approach. The research stages included phage isolation (density assay), characterization (plaque morphology and host range testing), and evaluation of phage against A. hydrophila (bacteriolytic efficacy assay). A completely randomized design was employed, with six treatments and three replicates, media control (K-), A. hydrophila control (K+), antibiotic control (enrofloxacin 0.1 mg/mL, KA), and phage treatments at multiplicities of infection (MOI) of 0.1, 1, and 10 (P0.1, P1, P10) for the bacteriolytic efficacy assay. Phage isolated from catfish ponds in Dramaga, Bogor, exhibited a high titer (5.68 × 10⁹ PFU/mL) and formed clear, round plaques (0.17-0.35 cm diameter). They demonstrated a narrow host range, lysing only 1 of 10 A. hydrophila isolates. In efficacy assays, phage treatment at an MOI of 10 significantly reduced bacterial density (p < 0.05) at 24 hours post infection, decreasing the OD 600 nm by 38.7% compared to the positive control. These results indicate the potential of these phage as an antibiotic alternative for controlling A. hydrophila in aquaculture.

Abstract

Abstract Canarium indicum offers the potential of usage in aquaculture. This study aimed to evaluate the utilization of C. indicum on growth performance, health, and resistance of Asian seabass Lates calcalifer challenged with Vibrio alginolyticus. The study employed a completely randomized design with seven treatments, namely positive control (K+), negative control (K-), vitamin control (KVit), antibiotic control (KAnt), doses of 5 g kg-1 (D05), 10 g kg-1 (D10), and 20 g kg-1 C. indicum (D20). The test feed was prepared with a coating method and fed for 30 days. On the 31st day of rearing, a challenge test was conducted by injecting V. alginolyticus intramuscularly at 106 CFU mL-1. The results showed that C. indicum treatment for 30 days had a significantly different effect (P<0.05) on weight gain and average daily growth, while KVit and KAnt treatments were not different from the control. After the challenge test, all doses of C. indicum treatment, as well as KVit and KAnt treatments, showed survival significantly different (P<0.05) from that of the positive control, which ranged from 88.89% to 95.56% and was not significantly different (P>0.05) from the negative control. The survival rate condition is identical to the cumulative survival condition which shows the highest mortality found in the positive control. The administration of C. indicum at a dose of 5 g kg-1 to 20 g kg-1 improved the growth performance and prevented V. alginolyticus infection. Highlight Research C. indicum significantly increases the growth of Asian seabass. C. indicum significantly enhances the immune response to V. alginolyticus infection in Asian seabass. C. indicum can prevent V. alginolyticus infection as it resulted in a higher and cumulative survival than the positive control. C. indicum can be developed as an immunostimulant for the prevention of vibriosis in Asian seabass at doses of 5 g kg-1 to 20 g kg-1.

Abstract

Graphical Abstract Highlight Research vB_Vp_TSK01 and vB_Vp_JKT02 a specific parahaemolyticus bacteriophage were isolated from the shrimp aquaculture water. Compared to control vB_Vp_TSK01 reduced 11.46±1.35% of bacterial growth, and by 9.86±5.92% for vB_Vp_JKT02 treatment. Their cocktail had the highest parahemolyticus growth inhibition by 30.92±3.89%. The phage treatment increased the survival of the Artemia by 28.57% compared to infection control.     Abstract Acute Hepatopancreatic Necrosis Disease (AHPND) caused by V. parahaemolyticus infection was one of the major diseases in shrimp culture in recent years. The Vibrio could also affect the survival of Artemia as the shrimp’s main live feed in the hatchery and they become the possible carrier for the AHPND. Phage therapy in shrimp aquaculture could reduce the application of the antibiotic as an antibacterial agent for the AHPND. The present study aimed to isolate the specific lytic phage for the Indonesian strain of V. parahaemolyticus (Vp) and evaluate the phage therapy for the brine shrimp Artemia infected with the Vp. The Vp-specific phage was isolated from the shrimp farm’s water at Tasikmalaya, and North Jakarta City, Indonesia. After isolation and plaque assay, brine shrimp were used as a model to evaluate the phages’ anti-Vibrio activity The Vp-lytic phage was successfully isolated from shrimp culture water at North Jakarta and Tasikmalaya (Vb_Vp_TSK01 and Vb_Vp_JKT01, respectively) and the results showed that both isolated phages and their cocktails were capable to inhibit the growth of Vp with the highest inhibition shown at the cocktail treatment (p<0.05). The survival of Artemia was higher in the phage treatments (p<0.005) compared to the infected control. Infected control had 68.33% of brine shrimp survival, and the Vb_Vp_TSK01, Vb_Vp_JKT01, and their cocktail had similar average brine shrimp survival of 91.11%. In conclusion, phage therapy proved effective in preventing vibriosis in brine shrimp under the conditions tested.

Abstract

The search for sustainable feed alternatives has led to exploring unconventional sources, including food waste, amidst the growing demand for halal gelatin, which has created a significant need for fish skin by-products. Therefore, this study aimed to authenticate the halal status of catfish skin gelatin by verifying feed origin and determining the contents of pig contaminants. Halal standard was verified using a specific DNA analysis of pig components, conducted at each stage, including feed containing pig, fish skin, and catfish gelatin. Gelatin in catfish skin was predominantly composed of amino acids glycine and proline, and fish enlargement stage which led to a skin yield of 5.36 ± 0.75%. Furthermore, the yields of gelatin were 8.67%, 9.94%, and 9.19%, with gel strengths of 133.4 ± 1.2, 129.9 ± 1.4, and 121.9 ± 2.8 bloom, respectively, for the different quarantine periods. The characterization of gelatin using FTIR showed the presence of functional groups, such as amide A, I, II, and III. Real-time PCR detected the presence of pig DNA in feed but not in catfish skin or gelatin. In conclusion, a quarantine period of 0 days for catfish fed pig-containing feed was sufficient to cleanse catfish skin of pig contaminants, with no indication of pig DNA being found.

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

Whiteleg shrimp Penaeus vannamei cultured in marine floating net-cage systems are highly susceptible to stress and diseases caused by Vibrio harveyi. This study aimed to evaluate the effect of turmeric Curcuma longa and kalmegh Andrographis paniculata on the growth performance and immune system of whiteleg shrimp against V. harveyi infection. The study utilized a completely randomized design with treatments including control (C), one week (1W), two weeks (2W), and four weeks (4W) of supplementation. The challenge test consisted of C+, C-, 1W, 2W, and 4W treatments. Parameters observed included growth performance, immune response, and resistance to V. harveyi. Results showed that the combination of turmeric and kalmegh significantly improved final biomass, weight gain, specific growth rate, and feed conversion ratio compared to the control. Survival rates after challenge tests revealed the highest survival in the C- group (93.33 ± 5.77%), followed by treatment 4W (86.67 ± 11.55%), 2W (76.67 ± 20.82%), 1W (46.67 ± 35.12%), and the lowest in C+ (33.33 ± 26.46%) with significant differences (P < 0.05) across treatments. Immune responses, including total hemocytes, phagocytosis activity, phenoloxidase activity, and respiratory burst, were also significantly improved in the treatment groups compared to the positive control. In conclusion, the combination of turmeric and kalmegh (2:1 ratio, 6 mL/kg of diet) significantly enhances both growth and immune responses of whiteleg shrimp, offering a potential alternative to antibiotics for controlling vibriosis in shrimp aquaculture.

Abstract

The sustainability of Nile tilapia production faces challenges from motile Aeromonas septicemia (MAS), caused by Aeromonas hydrophila. The use of antibiotics to control MAS has negative impacts on aquatic environments and consumer health. As alternatives, plant-based treatments and vaccination have been increasingly applied to replace antibiotics. This study aimed to evaluate the effects of banana pseudo-stem (BS), a commercial vaccine (CV), and their combination (BS+CV) on the growth, health status, and immune performance of Nile tilapia against A. hydrophila. A completely randomized design was used with five treatments: a negative control (C−), a positive control (C+), BS, CV, and BS+CV—each coated onto feed. Each treatment had three replications. Fish were reared in 36-L aquaria for 42 days to evaluate growth performance, followed by a challenge test with A. hydrophila on day 43. Survival was monitored for 14 days post-challenge. The highest growth performance was observed in the BS treatment compared to the other treatments. Meanwhile, survival rate (SR) and feed conversion ratio (FCR) did not show significant differences (P>0.05) among treatments. After the challenge, survival rates in the BS (96.67%), CV (73.33%), and BS+CV (76.67%) groups were significantly higher (P<0.05) than in the positive control group (50.00%). The BS group did not differ significantly (P>0.05) from the negative control group (100.00%). These findings indicate that BS, CV, and BS+CV enhance the immune response of Nile tilapia against A. hydrophila, with BS being the most effective in improving both growth and disease resistance.

Abstract

Beberapa upaya yang dilakukan untuk menanggulangi adanya kanibalisme pada ikan adalah dengan pemberian hormon sintesis estradiol-17β dan pemberian asam amino triptofan (bahan baku biosintesis serotonin) dalam pakan. Tujuan penelitian ini adalah untuk mengevaluasi pengaruh pemberian tepung kedelai terhadap tingkat kanibalisme benih ikan lele. Tiga dosis perlakuan penambahan tepung kedelai yaitu: 0 (Kontrol), 50 (TK50), dan 100 g kg-1 pakan (TK100). Terdapat dua perlakuan kontrol yaitu penambahan hormon menggunakan 17α-metiltestosteron 30 mg kg-1 pakan (MT) dan estradiol-17β 50 mg kg-1 pakan (E2). Penelitian ini menggunakan benih ikan lele berukuran 2,90 ± 0,41 cm dengan padat tebar 2000 ekor m-2. Pemeliharaan dilakukan selama 30 hari dengan pemberian pakan dilakukan tiga kali sehari (07.00, 12.00, dan 18.00). Metode yang digunakan dalam penelitian ini adalah rancangan acak lengkap dengan menggunakan lima perlakuan yang masing masing diulang sebanyak tiga kali. Hasil dari penelitian ini menunjukkan bahwa penambahan TK100 pada pakan dapat meningkatkan tingkat kelangsungan hidup, menekan adanya kanibalisme serta ikan yang berpotensi kanibal (P<0,05). Hasil dari kinerja pertumbuhan menunjukkan bahwa nilai laju bobot mutlak, laju panjang mutlak, laju panjang spesifik, dan koefisien keragaman panjang memiliki hasil yang berbeda nyata antarperlakuan (P<0,05) dan perlakuan laju bobot spesifik tidak berbeda nyata (P>0,05). Penambahan tepung kedelai dalam pakan mampu menekan adanya kanibalisme pada benih ikan lele sebesar 21,21%. Penurunan kanibalisme tersebut sejalan dengan adanya peningkatan kelangsungan hidup pada benih. Suplementasi tepung kedelai dalam pakan dapat menjadi alternatif solusi untuk penurunan tingkat kanibalisme pada pemeliharaan benih ikan lele.Several attempts have been made to reduce cannibalism in fish by supplementing the synthetic hormone estradiol-17β and amino acid tryptophan (raw material for serotonin biosynthesis) in feed. This study aimed to evaluate the effect of soybean meal on the level of cannibalism of catfish fingerlings. Three treatment doses of the supplementation of soybean meal were 0 (Control), 50 (TK50), and 100 g kg-1 feed (TK100). There were two control treatments, with the addition of hormones using 17α-methyltestosterone 30 mg kg-1 feed (MT) and estradiol-17β 50 mg kg-1 feed (E2). This study used catfish fingerlings measuring 2.90 ± 0.41 cm with a stocking density of 2000 m-2. The experiment was conducted for 30 days, thrice daily feeding (07.00, 12.00, and 18.00). The experiment was arranged in a completely randomized design using five treatments with triplicates. The results show that TK100 produced an increased survival rate and suppressed cannibalism level and potentially cannibalistic fish (P<0.05). The growth performance results show that the total weight rate, relative length rate, specific length rate, and length variation coefficient of catfish fingerlings were significantly different among the treatments (P<0.05). However,  the specific weight rate of catfish fish fingerlings was not significantly different among the treatments (P>0.05). The supplementation of soybean meal in feed suppresses cannibalism in the catfish seeds by 21.21%. The decrease in cannibalism was strongly correlated with the increase in the fingerlings’ survival rate. Supplementing soybean meal in feed can be an alternative solution to reduce cannibalism in catfish seed rearing.
