Effect of Melia Azedarach Extract on Some Selected Physiological Parameters of (Catla catla)

Abstract

The present study has been carried out the effect of leaf extract of Melia azedarach at different concentration, such as 1.0g, 1.5g and 2.0g formulated diet against 0.1 ml of CFU/ ml 10 5 cells Aeromonas hydrophila on catla catla. The physiological parameters, such as Survival and Mortality, Antibody response, Phagocytic activity, Oxygen consumption, opercular movement, and Growth rate were studied. Result revealed that control fish showed 60% mortality and 20%, mortality at 1.0g concentration of plant extract, 10% mortality at 1.5g concentration of plant extract 30% mortality at 2.0g concentration of plant extract was observed. The maximum level of physiological activity Survival and Mortality, Antibody response, Phagocytic activity, Oxygen consumption, opercular movement, and Growth rate was recorded at 1.5g of plant extract formulated diet treated fish. When compared with control, However physiological parameters was significantly (p<0.05) increased when compared with control. Materials and Methods Alive and activity fishes (12± 1g) were collected from High-tech fish farm, Madurai, Tamil Nadu, India. The fishes were maintained in non-chlorinated at 20 day. The ground nut oil cake, fish meal and rice bran, tapioca, soybean, were mixed and sterilized. And then add a multivitamin tablet. The above mixed foods were added with different concentrations (1.0g, 1.5g and 2.0g) of plant extract prepared using shoxlet apparatus. These extract Melia azedarach extract used for experimental fishes and without plant extract diet for control fish. The food was made into small pellets. 0.1 ml of 10 CFU/ ml of Aeromonas hydrophila was injected intraperitoneally both for control and experimental. In every seven days following physiological studies such as,(Table 1).

The role of currently used medicinal plants in aquaculture and their action mechanisms: A review

“…Feeding 15 g/kg Tamarind pulp extract promoted growth, nutrient digestibility of Nile tilapia and protection against A. hydrophila infection 204 . Administration with 1.5 g/kg Melia Azedarach extract, 4–6 g/kg Mucuna pruriens and 0.5–2 g/kg jojoba extract improved the resistance against A. hydrophila in Catlacatla , 205 Oreochromis mossambicus 206 and Oreochromis niloticus 207 respectively. After A. hydrophila infection, 40% M .…”

An update about beneficial effects of medicinal plants in aquaculture: A review

“…A tamarind (Tamarindus indica L.) pulp extract (15 g/kg) promoted the growth and nutrient digestibility of Nile tilapia, and provided protection against an A. hydrophila infection (Adeniyi et al 2021). The addition of a 1.5 g/kg chinaberry tree (Melia Azedarach) extract, a 4-6 g/kg velvet bean (Mucuna pruriens) extract, and a 0.5-2 g/kg jojoba extract to the diet improved the resistance against A. hydrophila in Catla (Labeo catla) (Rajeshwari et al 2016), Mozambique tilapia (Oreochromis mossambicus) (Saiyad Musthafa et al 2018), and Nile tilapia (Sarhan et al 2019), respectively. A supplementation of 40% moringa (Moringa oleifera) leaf extracts to the diet of carp infected by A. hydrophila enhanced the growth, antioxidant and immune response of the carp (Zhang et al 2020a).…”
