Abstract :
This study was performed in 2013 with the aim of increasing productivity in Barbus grypus and Barbus sharpeyi breeding, together with culture ducks in a period of 8 months, from April to December, in Hantoushzadeh culture farm, in Dolati village of Dezfoul city in Khuzestan province. In this study 2 random treatments were designed and every treatment was performed in a pool of 3 hectares. In both treatment and control pools 900 pieces of fish consisting of 450 pieces Barbus grypus and 450 pieces of Barbus sharpeyi (50% Barbus grypus, 50% Barbus sharpeyi) with an average weight of 20.62±8.67 and 21.5±7.77 g. In the treatment pond 1350 ducks of 15 days old of 300±47.56 g were introduced in 3 stages at intervals of beginning of the period and at the second and third months. The average temperature in the treatment and control ponds were 28.68 ± 2.92 °C. The pH in the treatment and control ponds was 8.70±0.68 and 8.61±0.55, respectively. As the weight average of Barbus grypus and Barbus sharpeyiin the treatment pond were 1126.6g and 770g,therefore the average production of the two species, was 506970±255.23g and 346500±486.55g respectively. Considering that in the control pool, the weight averages of Barbus grypus and Barbus sharpeyi were 1050 and 660g respectively, and the production was 472500±138.48g and 297000±172.76g, an increased production is noticed in pond with ducks (treatment pond) (P<0.05). In the treatment pond the initial and final weights of breeding ducks were 300±47.56 and 310±59.38 g, respectively. Considering that the weights of ducks rose to 3100 g, the duck meat production was 4185000 per hectares.In general it can be concluded that integration of fish breeding ponds with duck farming increases fish production and efficiency. There is also an increase in the production of duck meat.
