Abstract
Growth and survival rate are the most crucial in commercial culture as well as feed
quality, and it's pricing. This study aimed to obtain the effect of different dose of MOS to the
growth and survival rate early big pencil size of shortfin eel Anguilla b. bicolor. Three
replications with four treatments of feed containing 0, 0.1, 0.2, and 0.3 % doses of MOS (noted
as T0, T1, T2, and T3) were administered during 84 days culture. The fish were fed with 2.2%
wet basis d-1 of commercial shrimp feed combined with catfish feed. Initial density of approx.
5 kg seed stock of early big pencil eel in 0.4 m3 recirculating water system. The result indicated
that absolute, individual and biomass-specific growth rate (SGRi/b) have the similar patterns
corresponds to the dose of MOS. The highest SGRi was T3 (0.69±0.05% d-1
) followed by T2
(0.60±0.03% d-1
), T1 (0.46±0.04% d-1
) and T0 (0.44±0.03% d-1
). Meanwhile the SGRb shows
significantly different (α < 0.05) between T3 (0.66±0.05% d-1
) and T2 (0.57±0.04% d-1
), but no
significantly different (α > 0.05) between T1 (0.43±0.05% d-1
) and T0 (0.40±0.02% d-1
), and
both of T3 and T2 have significantly different (α < 0.01) to T1 and T0. The best SR was in T2
(98.0 %), followed by T1 (97.5 %), T3 (97.3 %) and T3 (96.4 %). Hence, the MOS gave a
positive impact on growth and slightly gave a different effect on survival rat
