Abstract
It can be concluded that S. denisonii larvae fed with
artemia flake diets (AFD) exhibited significantly
better growth and survival rate than other three
experimental diets (MWD, VFD and HFD). However,
Paramecium is essential in the initial stage of
larval rearing of S. denisonii as live feed, because
larvae are usually very small and fragile with an
undeveloped digestive system (Singh et al., 2012).
Absorption of endogenous food reserves, or more
accurately the transition from endogenous to exogenous
nutrition, is also a critical developmental and
ecological transition for fish larvae (Kamler, 2008).
Present findings also emphasize the potentiality of
micro worms as an alternative for artemia naupli in
larval rearing of S. denisonii like other ornamental
fish such as Carrassius auratus L. and Poecilia
reticulata (Parameshwaran et al., 2001; Schlechtriem,
2004) and thereby production cost can be minimised.
This study represents an important step for successful
rearing optimization of the S. denisonii under
controlled conditions and the live feeds were found
to significantly affect early survival rate in this
species. These findings could be beneficial for the
development of better larval rearing techniques for
Sahyadria denisonii under hatchery conditions
