Effect of integrated duck-fish farming on growth performance and economic efficiency of Nile tilapia (Oreochromis niloticus L.) [electronic resource].

Includes reference.

This trial was conducted for 200 days/year started on April to October, years 2004 and 2005 to evaluate the effect of two stocking densities of ducks along with a control (without ducks) on productive and economic efficiency of Nile tilapia in ponds. . Four earthen ponds were used in the non-integrated system (no ducks, T1), two ponds/year, whereas four earthen ponds, two ponds/year were supplied with 1000 (T2) and 1500 (T3) Peking ducks per feddan (fdn)/cycle at years 2004 and 2005 (two cycles/year), were used for the integrated system. Each pond was stocked with Nile tilapia (Oreochromis niloticus) fry (9.0 ± 0.38 g) at a rate 15000/fdn.
