fish with higher concentration of dietary supplementation
(Sharma et al. 2010; Kumar, Raman,
Pandey, Mohanty, Kumar & Kumar 2012). Due to
their effectiveness at low concentration, its use
could be very cost effective. It is biodegradable and
hence environment-friendly. Thus, O. sanctum
seems to have potential as an additive to fish feed.
However, appropriate field trials remain necessary
before using O. sanctum leaf extract as an immunostimulant
in aquaculture farm.
