No results found.This study was conducted to evaluate survival, growth, production, food conversion and economic feasibility in the monoculture of prawn (Penaeus monodon) at two stocking densities (15,000 juv/ha and 20,000 juv/ha) following modular pond system. Four sets of existing modular ponds at SEAFDEC, Leganes Research Station were used for this study. Each set forms a three-stage link-up. The area of each set is increasing progressively in a ratio of 1:2:4 proportion or a corresponding ratio of 550, 1100 and 2,200 m2 respectively. Using this method, prawns were grown and were provided a better utilization of space and increased number of croppings (six crops a year) than previously realized in straight-run culture. On Treatment 1 and Treatment 2 growth, survival rate and final body weight of the prawn showed that there were no significant differences between the two treatments. Observed significant differences was on greater average production of the prawn achieved which was 533 kg/ha in Treatme nt 2 than 404 kg/ha production in Treatment 1. Economic analysis for Treatment 1 and Treatment 2 showed that returns on investment were 69.5 and 72.0%; the payback periods were 1.4 and 1.3 years, respectively.
