The present study was done to assess the
effect of Ascorbic Acid on growth rate of clarias
batrachus fry. The fry were fed with A.A enriched
infusoria diet for a 60 days. Infusoria is given with
ascorbic acid enrichment with different concentration
i.e. 5%, 10%, 15% in different treatment T1, T2, T3
respectively with 0% enriched infusoria i.e. Non
enriched infusoria in control group. The AA is added in
infusoria through bioencapsulation. Clarias batracus fry
of weight 2-3 gm and were randomly distributed in each
plastic tank of 100 l. Initial and final weight was
measured at every interval of 7 days. After the culture of
infusoria Ascorbic acid is added at different
concentration and fed to fry in each tank thrice a day.
T3 shows highest weight gain and specific growth rate
followed by T2, T1 and control group. Thus T3 shows
highest growth and control group shows poorest growth
in control group.
