Abstract: Plant extracts are focused for their potential as immunostimulants against the infectious diseases of fish. The present study was designed to evaluate the acquired immunity stimulated by methanolic extract of
Andrographis paniculata against the pathogens,
Aeromonas hydrophila and
A. veronii in
Catla-catla. The fishes were fed with diet incorporated with A
. paniculata extract. Post 14 days, serum parameter analyses revealed an increase in total haemoglobin (10-11.5 g %), erythrocyte (34.7 10
5 mm
-3) and leukocyte count (3.9 × 10
4 cell.mm
-3). The phagocytic index of infected fishes treated with extracts increased in a dose dependent manner (31.25%), exhibiting 100 % Relative Percentage Survival. Adverse changes in the disease symptoms were also observed post treatment with extracts. The extracts of
A. paniculata were able to inhibit the pathogens even at low concentration (50 µl). This study hence proves that the extracts of
A. paniculata can be used as an immunostimulants.
