Resumen
Descripción
Seven farmers took part in rice-cum-fish trials in Luapula Province during the rainy season 1992–93. The rice variety Supa was grown for 6 1/2 to 7 1/2 months, and two fish species, Tilapia rendalli and Oreochromis macrochir, were stocked at 50 fingerlings per 100 m2 and grown for 4 1/2 months. The rice harvest from the rice-cum-fish field was on average 11% higher than that from the rice-only field. The average fish yield was at the same level as that recorded during rice-cum-fish farming trial s in Philippines and Madagascar. But the net return to land and labour was lower for rice-cum-fish farming than for rice-only farming. Hence the economic viability of rice-cum-fish farming was not proved. The main reason for the negative results appears to be the amount of labour expended on fish production, particularly feeding. However, the seven farmers who took part in the trials intend continuing with rice-cum-fish farming, as they believe it has potential.
