ABSTRACT
An experiment was conducted to evaluate the reproductive performance and offspring quality of Macrobrachium vollenhovenii broodstock fed four diets: commercial maturation feed (control, T0), maggot (T1), fresh mackerel (T2) and locally formulated feed (T3). Spent broodstock of M. vollenhovenii fed experimental diets and their reproductive performances were evaluated in phase one experimentation. In phase two their offspring quality in a recirculation system with three replicates per treatment (TL0, TL1, TL2 and TL3) were evaluated for 30 days. The duration of gonadal development was significantly different among all the treatments, 28.67 ± 0.58 days and 16.33 ± 1.15 days for T0 and T1, respectively. T1 recorded the best GSI (16.08 ± 0.2%). Larval development in TL1 and TL3 were significantly faster than TL0 and TL2. However, survival rate was the best in TL3 (32.17 ± 0.57%) followed by TL0 (29.63 ± 0.33%). The results of this study are evidence of the possibility of successfully re-maturing and breeding this prawn in captivity.
