Eight hundred and eighty-¢ve strains of bacterial isolates
fromvarious samples associatedwith the natural
habitat ofMacrobrachiumrosenbergii were screened
for their probiotic potential. Two putative probionts
namely Bacillus NL110 and Vibrio NE17 isolated from
the larvae and egg samples, respectively, were selected
for experimental studies and were introduced
to the juveniles of M. rosenbergii (0.080 0.001g)
through di¡erent modes such as through feed, water
and both. The probiotic potential of the above bacteria
in terms of improvements inwater quality, growth,
survival, speci¢c growth rate (SGR), feed conversion
ratio and immune parameters was evaluated. The
treatment groups showed a signi¢cant improvement
in SGR and weight gain (Po0.001). Survival among
di¡erent treatment groups was better than that in
the control group. There were also signi¢cant improvements
in the water quality parameters such as
the concentration of nitrate and ammonia in the
treatment groups (Po0.05). Improvements in immune
parameters such as the total haemocyte count
(Po0.05), phenoloxidase activity and respiratory
burst were also signi¢cant (Po0.001). It is concluded
that screening of the natural micro£ora of cultured
¢sh and shell¢sh for putative probionts might yield
probiotic strains of bacteria that could be utilized for
an environment-friendly and organic mode of aquaculture |
