Abstract

Moringa leaves can be used as an herbal plant in fish growth to prevent and treat bacterial infections. This study aims to determine the effect of fermented moringa leaves through feed on blood glucose in striped catfish (Pangasianodon hypophthalmus). This research was conducted from September to November 2023 at the Marine Biotechnology Laboratory, Faculty of Fisheries and Marine Sciences, Riau University. The method used is an experimental method using a completely randomized design with 4 (four) treatments and 3 (three) replicates; the treatment dose of fermented moringa leaves is T0 (control), T1 (10 g/kg feed), T2 (15 g/kg feed), and P3 (20 g/kg feed). The catfish measured 5.00 ± 1.00 cm and weighed 4.00 ± 0.50 g, reared in an 80 L tank at a stocking density of 1 fish / 4 L water. The maintenance was carried out for 60 days, and blood glucose observations were made at the beginning (H-1), day 30 (H-30), day 60 (H-60), and post-challenge test (H-75). The results showed that adding fermented moringa leaves to the diet did not affect the blood glucose of the catfish (p>0.05). This indicates that moringa leaves can keep the fish in normal condition after being challenged with Aeromonas hydrophila bacteria

Abstract

Aquaculture intensification increases fish susceptibility to infectious diseases, prompting the search for natural alternatives to reduce dependence on synthetic chemicals. Bandotan leaves (Ageratum conyzoides L.) of the Asteraceae family contain secondary metabolites, including flavonoids, alkaloids, terpenoids, and saponins, with antibacterial, antioxidant, and immunomodulatory activities. This literature review aims to analyze the potential of bandotan leaves as a natural immunostimulant and antibacterial agent in aquaculture, focusing on their phytochemical content, mechanism of action, and safety. This study used a literature review method, conducting searches across national and international journal databases, university repositories, and research institute publications. The inclusion criteria included articles discussing the biological aspects, phytochemical content, antibacterial activity, immunomodulatory effects, physiological parameters, histology, and safety of bandotan leaves in the context of aquaculture. The results of the study showed that bandotan leaf extract effectively inhibited the growth of pathogenic bacteria in fish by disrupting cell membrane integrity and inhibiting bacterial enzymes. Its bioactive compounds enhance immune response, antioxidant activity, and reduce metabolic stress in fish. However, its application faces challenges in determining the optimal dosage, assessing histopathological effects, and managing potential respiratory distress at high concentrations. Further research is needed to optimize the formulation, understand the molecular mechanisms, and ensure the long-term safety of bandotan leaf use in sustainable fish farming systems.
