Description A 30 days feeding trial was conducted to evaluate the effects of Cassia auriculata leaf powder on growth and
immunomological parameters of the juveniles of Milkfish, Chanos chanos and disease resistance against Vibrio
anguillarum. The juvenile fishes with an average weight of 20±3 g were stocked in four treatments each with
three replicates. Four practical diets were prepared with graded level of Cassia auriculata leaf powder (CAL) at the
rate of 0%, 0.5%, 1% and 1.5% and fed to four treatments respectively named as CAL0, CAL0.5, CAL1 and
CAL1.5. At the end of the experiment blood samples were collected for immunological parameters. After
sampling, the remaining fishes were challenged with 0.1 mL of virulent V. anguillarum suspension at a concentration
of 107
CFU mL-1 and mortality was observed for 7 days. Post challenge sampling was performed for the collection
of blood samples. The growth parameters such as Weight gain%, SGR%, PER were positively affected by Cassia
auriculata leaf powder incorporated diet. Higher weight gain %, SGR% and PER were noticed in CAL1.5 group
followed by CAL1, CAL0.5 and CAL0. The respiratory burst, lysozyme and phagocytic activities were increased
with increasing level of CAL in the diet which indicates better immune response of the fishes fed with CAL. The
higher respiratory burst (0.522 ± 0.03), lysozyme (70.07 ± 1.57) and phagocytic (52.91 ± 1.76) activitieswere
observed in CAL1.5, CAL1 and CAL1.5 groups respectively during pre-challenge and post challenge. There was
significant difference in the survival rate of control (CAL0) and CAL incorporated diet fed groups (P
