“…causing vibriosis (Brackman et al 2008). S. cumini leaf powder also reported to increase immunity in juvenile shrimp (Litopenaeus vannamei) against V. parahaemo lyticus infection (Prabu et al 2018). Organic solvent extracts of A. sativum and S. aromaticum also reported to significantly increase the survival of Oreochromis niloticus from infection against E. faecalis (Rahman et al 2017).…”

Penaeus monodon is highly susceptible to vibriosis disease. Aims of the study were to identify the pathogen causing vibriosis in P. monodon through molecular techniques and develop a biocontrol method of the disease by application of herbal extracts. Shrimp samples were col¬lected aseptically from the infected farm and the bacteria were isolated from the infected region of those samples. Based on phenotypic identification, several isolates were identified as Vibrio sp. 16S rRNA gene sequences of the selected isolates exhibited 100% homology with V. alginolyticus strain ATCC 17749. An in vivo infection challenge test was performed by immersion method with V. alginolyticus where these isolates caused high mortality in juvenile shrimp with prominent symptoms of hepatopancreatic necrosis. Antibiogram profile of the isolates was determined against eleven commercial antibiotic discs whereas the isolates were found resistant to multiple antibiotics. A total of twenty-one herbal extracts were screened where Emblica officinalis, Allium sativum, and Syzygium aromaticum strongly inhibited the growth of V. alginolyticus in in vitro conditions. In in vivo conditions, the ethyl acetate extracts of E. officinalis and A. sativum successfully controlled the vibriosis disease in shrimp at a dose of 10 mg/g feed. This is the first report on molecular identification and biocontrol of V. alginolyticus in shrimp in Bangladesh.

“…Growth-promoting properties of various plants in aquatic animals are well reported (Reverter et al, 2014;Panase et al, 2018). The previous report indicated that Pacific white leg shrimp fed the diet containing S. cumini leaf power at 1% for 28 days produced a significant enhancement of growth indices including WG, SGR, and protein efficiency ratio compared with the control (Prabu et al, 2018). Mohammadi et al (2018) found that common carp (Cyprinus carpio) fed the diets containing 0, 0.5, 1, 2, and 4% date palm (Phoenix dactylifera) seed extract for 60 days showed a significant improvement in growth parameters and feed utilization efficiency.…”

“…Recently, it has been reported that Pacific white leg shrimp (Litopenaeus vannamei) fed the diets supplemented with S. cumini leaf powder at 1% for 28 days potentially improved growth and non-specific immune parameters as well as the protection against Vibrio parahaemolyticus (Prabu et al, 2018). This scientific evidence would lead to support S. cumini as a potential phytogenic additive in aquatic diets.…”

This research was aimed to evaluate the effects of dietary supplementation with dried S. cumini flesh (DSCF) on growth and physiological parameters in hybrid catfish (Clarias macrocephalus × C. gariepinus). Fish (initial weight of 14.00 ± 1.00 g) were divided into four groups and fed with the diets containing DSCF at 0 (control), 1, 3 and 5% / kg diet for 8 weeks. After the experimental period, final weight, final length, weight gain, specific growth rate, average daily gain, and feed conversion efficiency were markedly increased, whereas feed conversion ratio was significantly decreased in the treated fish compared with the control fish (P<0.05). The condition factor and survival rate did not differ significantly among the treatments (P>0.05). Intestinal morphology was significantly improved in fish fed with DSCF containing diets (P<0.05). No changes in white blood cell, red blood cell, hemoglobin, and hematocrit were observed between the treatments (P>0.05). Meanwhile, the platelet was significantly increased in the tested fish compared with the control fish (P<0.05). Aspartate aminotransferase, albumin, total protein, creatinine, uric acid, and triglyceride levels did not differ significantly between the treatments (P>0.05). Serum glucose in fish fed with DSCF diet was significantly increased, while serum alkaline phosphatase was significantly lowered in the experimental groups compared to the control group (P<0.05). Overall, these results indicate that the usefulness of DSCF as a phytogenic additive in aquafeeds with an effective level rage from 2.60 to 2.72%/kg diet.

“…Two other treatments were positive control of antibiotic oxytetracycline at 0.05 mg/mL and negative control of NaCl 0.85%, respectively. Challenge test was conducted according to Prabu et al [9] on day 7 by injecting 105 CFU/ mL of V. harveyi using intramuscular injection on the dorsal part because there was evidence that the injection method had a better route to induce infection than immersion. The experiment was performed for 21 days.…”

“…This is because shrimps rely on the non-specific immune system and possess antioxidant activity to reduce the adverse effect of environmental perturbations [7]. In the past decades, explorations on medicinal plants as a source of growth-promoting agents, antibacterial, and antioxidants have received a growing interest in dealing with the undesirable effect of costly synthetic antibiotics [8,9].…”

Background and Aim: There has been continuous effort to search for alternative medicinal plants that are applicable to ameliorate viral disease on shrimp pond. This study aimed to examine the effect of Acanthus ilicifolius leaf extract on clinical symptoms and non-specific immune response of black tiger shrimp (Penaeus monodon). Materials and Methods: A total of 330 shrimps were equally assigned into three extract forms (crude extract, ethyl acetate extract, and n-butanol extract, respectively) in which three levels were provided for each extract. Negative control (without leaf extract) and positive control (with oxytetracycline at 0.05 mg/mL) were used, giving a total of 11 experimental treatments. Results: The results showed that shrimps induced into all form of leaf extracts had significantly higher survival rates, clinical symptoms, and pathological anatomy than those negative control (C–) and positive control (C+). Total hemocyte cells, granulocytes, percentage of phagocytic, and prophenoloxidase activity were similar among leaf extract treatments (p>0.05), but those groups were significantly higher than those of C– and C+ (p<0.05). Conclusion: n-butanol leaf extract at 300 mg/L is suggested to be the most effective treatment since it showed the highest efficacy on the parameters observed. Thus, it is possible to use the leaf extract of A. ilicifolius on-farm as a strategy to enhance bacterial disease resistance and prevent mortality.
