Abstract
This study reports the effect of a probiotic strain Pseudomonas
pseudoalcaligenes on growth of rohu (Labeo rohita) fingerlings. The
growth was assessed by morphometric measurements, feed conversion
ratio, feed conversion efficiency and protein efficiency. The formulated
fish feed was fermented by P. pseudoalcaligenes. Which was introduced
in fish aquaria @ 3% b.w.t. in two forms; with live bacteria (SSF1) and
without live bacteria (SSF2). In 90 days experiment, morphometric
measurements were made fortnightly. SSF1 showed significantly better
growth performance than those of SSF2 and control groups. At last phase
(90 days), SSF1, SSF2 and control groups showed FCR as 1.68, 2.28,
2.20 and FCE% 59.53, 44.75, 45.38 respectively. Both groups showed
wet body weight gain than control group at all phases while significantly
better weight gain was recorded in SSF1 group. Furthermore, SSF1
showed increased protein efficiency ratio (0.43) than SSF2 and control
groups. These results clearly indicate the importance of probiotics and
fermentation technology in aquaculture science.
