“…Fish treated with immunostimulants usually show enhanced phagocytic cell activities (Abarike et al., 2019). However, some earlier studies have reported lower haematological indices compared to control after treatment with herbal plant extracts (Gabriel, 2019). Neutrophil percentage was observed to substantially decrease in ET, MA and MM in the present study as well.…”

“…The presence of steroidal saponins in EB, ET and MA might be responsible for growth induction of fish in those treatment groups in the present study. Polysaccharides in medicinal herbal extracts have been reported to possess prebiotic properties, and thus improve gastrointestinal morphology or digestive systems, increase nutrient digestibility, absorption and assimilation capacity of fish (Gabriel, 2019). Herbs have also been observed to positively influence eating patterns, secretion of digestive fluids and total feed intake (Syahidah et al., 2015).…”

“…MT was reported to have no effect on haematological parameters (Abo‐Al‐Ela et al., 2017), but we observed haemolytic activity of MT in Nile tilapia in the present study. Significantly lower ( p < .05) total RBC, haemoglobin and Ht values in fish fed MT‐fortified diet might adversely affect the oxygen carrying capacity of fish in that group (Gabriel, 2019). Total WBC count in fish blood has been found to depend on many factors and be extremely variable even between conspecific individuals under similar conditions (Ighwela et al., 2012).…”

“…Asparagus racemosus has been reported to have medicinal values, various therapeutic uses and aphrodisiac effects in mammals (Alok et al., 2013). Various studies have also indicated the use of different medicinal herbs as a whole or parts in a crude powdered form or as extracts/compounds from the whole plant or parts to induce sex reversal, growth and immunostimulation in Nile tilapia (Gabriel, 2019). Dietary supplementation with Aloe vera powder was observed to increase male percentage (Gabriel et al., 2017), and improve growth, feed utilization and haemato‐biochemical parameters (Gabriel, et al., 2015) of genetically improved farmed Nile tilapia.…”

“…The parameters observed included feed consumption (Gabriel, 2019); blood count, included total erythrocytes, total leukocytes (Blaxhall & Daisley, 1973); and hemoglobin levels (Wedemeyer & Yasutake, 1977); respiratory burst activity (Anderson & Siwicki, 1993); lysozyme activity (Ellis, 2011); interleukin-1 gene expression (Buonocore et al, 2005); and survival rates (Biswas et al, 2011).…”

Asian sea bass is one of economically important commodities in aquaculture. However, its culture often challenged by vibriosis infection which resulted in lower production. The study aimed to evaluate the effectiveness of the ambon banana plant powder application in feed as an effort to control the disease caused by Vibrio alginolyticus infection. Asian sea bass with total length of 7.48 ± 0.45 cm. Five different treatments were applied in this experiment, i.e. positive control, negative control, prevention, curative, and antibiotic application. The challenge test is carried out on the 15th day. Challenge test was performed with intramuscularly injection of V. alginolyticus at the cell density of 106 CFU/fish. The results showed the amount of feed consumption after the challenge test was highest in the curative and antibiotic control. However, these results were not significantly different (P>0.05) among preventive and curative treatments but were significantly different from controls (P<0.05). Fish treated with supplemented feed showed the highest total erythrocytes, total leukocytes, hemoglobin, respiratory burst, and lysozyme activity compared to controls. IL-1b gene expression increased after the challenge test with the highest level of expression in the curative treatment. It can be concluded that the administration of ambon banana plant powder (3 g/100 g diet) could control of V. alginolyticus infection in Asian sea bass and resulted 70.00% survival rate on prevention and 83.33% on curative treatments.

Isolation and Characterization of Aeromonas jandaei from Nile Tilapia in Lake Volta, Ghana, and Its Response to Antibiotics and Herbal Extracts

et al. 2022

Production of Nile Tilapia Oreochromis niloticus contributes to economic growth in many countries. However, there has been a decline in its production over the years due to the influx of bacterial infections, with Aeromonas jandaei as an emerging threat. In this study, we identified and characterized A. jandaei from cage‐cultured Nile Tilapia in Akosombo Stratum II of Lake Volta in Ghana and evaluated its response to commonly used antibiotics using the disc diffusion and agar well diffusion methods for herbal extracts at various concentrations (10, 30, 50, 70, and 100 mg/mL). The herbs considered included guava Psidium guajava leaf, bitter leaf Vernonia amygdalina, neem Azadirachta indica leaf, and their cocktail (GBNL in the ratio of 1:1:1). The bacterium was isolated from swab samples from the head kidneys of 27 moribund Nile Tilapia collected from nine fish farms. Samples were screened for A. jandaei by culturing and identification using morphological and molecular techniques. The bacterium isolate from fish in the study, identified as A. jandaei GH‐AS II, had 92–93% identity to A. jandaei reference strains. Infection of healthy Nile Tilapia (n = 210) with the bacterium isolate showed that 1.0 × 105 CFU/mL was the lethal dose causing 50% mortality. Antibiotic susceptibility testing showed that A. jandaei GH‐AS II was resistant to tetracycline and ampicillin. Herbal extracts at the various concentrations inhibited the growth of the bacterium isolate, with a significant increment in the zones of inhibition with increasing concentrations of leaf extracts. However, GBNL showed prominence compared to the other extracts only at 100 mg/mL. Management of A. jandaei GH‐AS II by using herbal extracts at Nile Tilapia farms in Lake Volta may be recommended since the use of antibiotics, such as tetracycline and ampicillin, may not yield the needed result.
