Abstract

Highlight Research The dose, duration of immersion, and time interval of immersion of the estradiol-17β affect the rate of cannibalism and increase the seed survival of Asian redtail catfish in low treatment in this research. Over optimum treatment increased the incidence of cannibalism at Asian redtail catfish and decrease growth performance. Treatment of estradiol-17β, give the ability of Asian redtail catfish to live on high density The treatment of estradiol-17β, has an effect on concentration plasma of body testosterone and cortisol   Abstract The cannibalistic behavior of Asian redtail catfish greatly hampers the supply of these fish seeds, invoking the need to be controlled. Estradiol is one of the hormones that has been known to reduce cannibalistic behavior on fish. This study aimed to evaluate the effect of estradiol-17β immersion on the incidence of cannibalism in the rearing of post larvae of Asian redtail catfish. Post larvae was treated with a combination of doses of estradiol hormone 0, 1, and 2 ppm and immersion time of two and four hours with immersion intervals of three and six days with a completely randomized design. Each treatment had a fish density of 10 fish L-1, with mean size individual length of 6.73 ± 0.73 mm (three days of age after hatched), with four replications. Fish were fed with tubifex up until satiation point and reared for 30 days. The results showed that the administration of the estradiol-17β through immersion with a dose of 1 ppm for two hours and interval of six days was able to reduce the level of cannibalism and increase the survivability. A further increase in dose, immersion time, and interval had the opposite effect. Estradiol-17β immersion with certain dose, duration, and interval affected the rate of cannibalism, growth rate, and survival. Estradiol-17β immersion at a dose of 1 ppm for two hours and six days interval was the best to reduce the level of cannibalism and normal mortality in post larvae of Asian redtail catfish.

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

Abstract Dayak onion (Eleutherine bulbosa (Mill.) Urb.) has the potential to be an immunostimulant to benefit fish health. This study aimed to evaluate the effectiveness of dietary supplementation with the powder and crude ethanol extracts of Dayak onion on the hematology and immune response parameters of Nile tilapia challenged with Aeromonas hydrophila. The research used a completely randomized design with six treatments and three replications. Nile tilapias were fed with Dayak onion (w/v) consisting of powders of 5% (P5), 10% (P10), and 15% (P15), while crude extract was 0.5% (E05) and given during rearing for 30 days. Positive control (C+) and negative control (C-) were used without Dayak onion. Nile tilapia in treatment C+, P5, P10, and P15 were injected with A. hydrophila 10⁶ CFU mL⁻1, while that in treatment C- was injected with phosphate buffered saline (PBS) intramuscularly. The results showed that the dietary with 15% powder and 0.5% crude extract significantly improved the hematology and immune response parameters compared to the control after the challenge against A. hydrophila (P<0.05). Dayak onion supplementation effectively increased the health status based on hematology and immune response parameters of Nile tilapia against A. hydrophila infection. Highlight Research Dayak onion has significant potential to improve nonspecific immunity in fish. Dayak onion improves hematology and immune response of Nile tilapia. Dayak onion can significantly regulate the immune system against A. hydrophila infection. Dayak onion significantly increases the production of the gene expression of IL-1β and TNF-α.
