Studies on the immouostimulant activity of Coriandrum sativum and resistance to Aeromonas hydrophila in Catla catla.

ABSTRACT

The present study was designed to evaluate the immunostimulant potential of Coriandrum sativum is fish Catla catla, post challenged with A.hydrophila. Fish were divided into 2 groups one received control diet, another received Coriandrum Sativum incorporated diet for 14 days. The haematological parameters and serum protein were analyzed between control and experiment. There was a significant increase in TEC (P<0.01) and TLC (P <0.01) in the immunostimulant (IS) administered diet. Remarkable increase in Hb content from as 6.9.to 7.39% and serum protein level from 0.56 to 0.58g% was noted. The immunostimulant administered post challenged Catla catla showed a decrease in TEC at 103 cfu/ml and a drastic increase in TLC(<0.01) in both 103 and 105 cfu/ml Hb content on IS incorporated post challenged Catla catla showed an increase from 8.7 – 11.5g%.
