On-farm trials with rice fish cultivation in the west Kano rice irrigation scheme, Kenya
The viability of integrating rice farming with fish culture was studied in ten (10) rice plots. The onfarm research was done during one rice-growing season starting May 2003. The rice variety used was IR 2793-80-1 while the fish species was the Nile tilapia, Oreochromis niloticus. The fish culture period lasted 77 days. An average fish production of 132.4 kg/ha was obtained. The mean recovery rate of tilapia was 43 per cent. Total rice yield from the fields stocked with fish was lower than from unstocked fields. The net returns were not significantly different.
