Abstract

Paddy cultivated areas in Malnad regions are transforming into fallow because of low economic returns from the paddy cultivation. Paddy cum fish culture system is the integrated approach which enhances the productivity of paddy as well as fish. In present investigation, performance of different fish varieties viz., Common carp, Red platy, Black molly, white molly and Red sword tail in paddy ecosystem (CTH-1 or Kempumukthi variety) was studied at AHRS, Kademadkal. Paddy and fishes were cultivated in the same field. The result revealed that, the growth (length and weight) was increased in the all the fish varieties. The survivality of all the fishes were more than 80 per cent except common carp fish. In paddy monoculture, 5300 m2 area of paddy produced the grain yield of 10.73 quintals and straw yield of 16.17 quintals. In paddy cum fish culture, 12.44 q/5300 m2 of grain yield and 18.74 q/5300 m2 of straw yields were produced. The grain and straw yield of paddy was higher in paddy-cum-fi
