Feasibility of adopting integrated rice-cum-fish culture system to enhance the development of conventional aquaculture participation in Niger State
2003
Yaro, I.
In a survey conducted to find out the status of integrated rice-cum-fish culture in Niger State, Nigeria, 0.37 ha of Fadama wetlands was utilized for rice-cum-fish culture and at experimental stage. In the case study of this rice-cum-fish model, the Nile Tilapia (Oreochromis niloticus) was involved. The result was that 1,4720 kg/ha/yr could be produced using chick manure application under rice-cum-fish culture model. The available records reveal that 233,079 ha out of 495,000 ha of estimated Fadama in Niger State was used for rice cultivation in 1997. If 233,079 ha were to be used for integrated rice-cum fish culture, it is estimated that 343,092 mt of fish (Oreochromis niloticus) could be produced per year. The fish demand in Niger State in 2002 was 50,000 mt. The NPK application under rice-cum-fish production gave the best rice production estimated at 43,968.0 kg/ha/yr. The percentage increase in rice yield as well as increase in net income due to introduction of fish was 10.1 % and 54.4% respectively. The culture system is therefore recommended for adoption towards greater participation in aquaculture development by the farmers
