Abstract: An experiment was carried out to assess the performance of Indian Ranner (IR), Khaki Campbell (KC), Zending (Z) ducks in an integrated duck-cum-fish farming system for a period of 15 months. Two hundred- seventy number 90-days-old duckling of Indian Runner, Khaki Campbell and Zending ducks fed (115g/duck day–1) on a formulated feed containing 18.41% crude protein and 2720.50 ME (kcal kg–1) of energy for grower ration and 16.68% crude protein and 2637.00 ME (kcal kg–1) of energy for layer ration. The results showed that the three genotypes were almost similar in body weight gain, mortality, egg production, feed conversion and egg weight (P>0.05). In respective of breed, egg production (nos./ duck) was inversely correlative (r = -0.33; P<0.001) with fish production (kg/duck). The total income from egg, fish, Spent duck and net profit per duck were almost similar in three breeds (P>0.05).
