Preliminary study on the construction and management of integrated rice-cum-fish culture system at Karabande, New Bussa

Details are given of a study carried out in Nigeria, to introduce the practice of fish-cum-rice culture, using Sarotherodon galilaeus. Two plots each measuring 360m super(2) were used for this study and were compared with the farmer's two plots measuring 300m super(2) and 350m super(2). The plots were modified and had two central canals. Rice seedlings were transplanted into the plots after 19 days using a planting distance of 20 x 20cm. Three rice seedlings were planted per hole, using rice variety FARO 40, and grown for 90 days. About 240 and 180 S. galilaeus fingerlings of mean weight of 30g and 26g were stocked in the two experimental plots, respectively. They were fed with pelleted feed of 25% C.P. and monitored for 100 days. A yield of 22.8kg was obtained in plot A while 15.66kg was obtained in plot B. A rice yield of 250kg (i.e 5 bags) was obtained in each of the plots. The results obtained were compared with plots with no fish
