Inclusion of Monosex Tilapia (Oreochromis niloticus) with Freshwater Prawn (Macrobrachium rosenbergii) in Polyculture Systems in the Ponds of Coastal Region: Impact of Stocking Density of Tilapia on Production and Profitability
Journal Title: Journal of Experimental Agriculture International - Year 2016, Vol 13, Issue 3
Abstract
Experiment was carried out to ascertain the impact of stocking density of monosex tilapia (Oreochromis niloticus) on production and profitability in freshwater prawn (Macrobrachium rosenbergii) farming system over a period of 150 days at farmers’ shrimp ponds, Madrasha village, Bamorta union, Bagerhat district. There were three treatments viz. T1, T2 and T3 with tilapia of 10,000, 15,000 and 20,000/ha, respectively and each having three replicates. Density of prawn at 20,000/ha was maintained in all the treatments. Ponds were stocked with monosex tilapia and all male prawn juvenile. On average, 25 genera of phytoplankton and 6 genera of zooplankton were identified from pond water. Water quality parameters were within suitable ranges for tilapia and prawn in all the treatments. Mean weight of tilapia decreased significantly (p<0.05) with increasing stocking density but survival rate did not differ significantly. Higher production of prawn was obtained in T1 (950.4 kg/ha) followed by T2 (923.0 kg/ha) and T3 (805.2 kg/ha). On the contrary, production of tilapia was significantly higher in T3 (1,686.60 kg/ha) and T2 (1,587.60 kg/ha) than in T1 (1,310.0 kg/ha). However, the overall total production of tilapia and prawn was significantly (p<0.05) higher in T2 (2,510.60 kg/ha) and T3 (2,491.80 kg/ha) compared to T1 (2,260.40 kg/ha). Higher profit was also found in T2 (BDT 238,923.00/ha) followed by T1 (BDT 222,557.00/ha) and T3 (147,819.00/ha). Therefore, the results of the study implied that inclusion of tilapia at a density at 15,000/ha enhanced the total production and contributed greatly to earn higher profit.
