Abstract
This study was conducted to evaluate the growth rate, survival rate, and biomass of all-male monosex giant freshwater prawn Macrobrachium rosenbergii. The experiment is in a completely randomized design with threereplications applying two treatments: (1) treatment involving the shrimps with pincers at a random selection – the control group and (2) treatment involving the shrimps without pincers – the experimental group. Each replication was carried out in a 6m3 shrimp culture tank with the density of 15 shrimps/m3 and the salinity of 5o=oo. The initial weight and length of the selected shrimps reached 7.29±2.01g/ind, and 9.12±1.03 cm, respectively. The results showed that after 90 days of treatment breaking the pincers, each individual shrimp weighs 26.87 g/ and its body is 13.08 cm in length, but it was not significantly different from the treatment without breaking pincers. The survival rate and biomass of shrimp in the treatment of breaking pincers were 84.44% and 361 ± 14.50 g/m3, which were higher and statistically significant compared to those in the treatment without breaking pincers.
