ABSTRACT
The study aimed to investigate the effects of injecting mangosteen husk hot-water extracts (MHE) on immune and physiological factors in Macrobrachium rosenbergii. Different doses of MHE (10, 20, and 40 µg prawn-1) were injected into the prawns, and various immune and physiological parameters were evaluated. The results revealed that higher doses of MHE (20 and 40 µg prawn-1) led to significant increases in immune parameters, improved phagocytic activity, and clearance efficiency. However, certain parameters, such as phenoloxidase activity per granulocyte, plasma glucose, and lactate levels were decreased after injection. Moreover, prawns injected with MHE and subjected to hypothermal stress exhibited changes in haemolymph dopamine and norepinephrine. Prawns injected with MHE for 7 days showed increased survival rates when challenged with Lactococcus garvieae. The relative survival percentages were 11.8%, 46.6%, and 47.1% for MHE doses of 10, 20, and 40 µg prawn-1 injection, respectively, indicating enhanced resistance to the pathogen. In conclusion, injecting MHE can act as an immunostimulant and physiological and neuroendocrine regulator for prawns, enhancing their resistance to L. garvieae.
