The present study was attempted first time to demonstrate the
immunostimulant potential of the jelly fish venom extract of C.
quinquecirha. The immunomodulation results were found to decrease
with the increasing concentration of the crude and fractions. Previously
some researcher have reported there was an excessive interest in the
modulation of the non specific immune response of fish to elevate the
general defense barriers and hence it increases resistance against
diseases through use of immunostimulant[12,13]. The use of immune
stimulants for prevention of diseases in fish considered an alternative
and promising area
