Effects of mannan oligosaccharide supplementation in the diet on growth performance and physiology of juvenile lobster, Panulirus polyphagus


Author(s): Do Huu Hoang

Abstract: The present study demonstrates the effects of dietary mannan oligosaccharide (MOS) on growth performance and physiology of lobster, Panulirus polyphagus (initial carapace length, CL ~6 mm). An experiment was executed with four treatments supplemented with increasing quantities of MOS, including 0% (control), 0.10%, 0.30% and 0.50% and fed the lobster for 8 weeks. Results revealed that after Eight Weeks of diet feeding, the lobster fed 0.30% MOS had the highest growth (average carapace length gain, ALG = 1.25 ± 0.07 mm wk-1), followed by the growth rate of lobster fed 0.50% and 0.10% MOS (ALG = 1.22 ± 0.07 mm wk-1 and ALG = 1.20 ± 0.05 mm wk-1, respectively). The lowest growth rate belonged to the lobster served the control diet (ALG = 1.09 ± 0.04 mm wk-1) (P< 0.05). The highest survival rates were groups of lobster fed 0.30% and 0.10% of MOS and were greater than the survival of the lobster fed the basal (P< 0.05). Perimeter ratios (PR) more developed in lobster fed MOS than PR value of losbters fed the basal diet (P< 0.05). Also, a level of 0.30% dietary MOS should be supplemented for lobster.
