Neo-females production and all-male progeny of a cross between two Indian strains of prawn (Macrobrachium rosenbergii): Population structure and growth performance under different harvest strategies

The cross tested herein demonstrated substantially higher yield than that obtained in previous studies, however, no statistically significant difference in net productions was found between the FH and SH treatments (2207 ± 130 versus 2163 ± 137 kg ha− 1, respectively). Cost-benefit analysis after nine months of grow-out showed higher profit and higher benefit-cost ratio in the FH group. However, the SH treatment resulted in more uniform marketable prawns and suggested a continuous cash flow throughout the grow-out period.
