The sustainable larvae productions incorporating biofloc technology might be one of
the best solution for development of mud crab industry. The research was conducted
on effects of biofloc on the production of Scylla paramamosain larvae. Biofloc
inoculums were added into treatment tanks to induce rapid formation of biofloc. The
duration of project were established for 30 days. Two replicates were prepared for
each experiment respectively. The mud crab larvae in control tanks were fed with
Artemia, while combinations of Artemia and biofloc were fed in treatment tanks. The
results showed S. paramamosain larvae fed with biofloc and Artemia have lower
survival rate compared to larvae fed with only Artemia. Larval Stage Index (LSI) was
used to determine the growth rate and transformation of larvae fed with Artemia and
biofloc into megalopa stage occurred earlier (day 27) compare to larvae fed with
Artemia only (day 28). Findings show that treatment experiment of 2 ml/L could be a
candidate for S.paramamosain larvae culture.
