Effects of doses of chicken manure on the biodiversity of zooplankton populations in ponds

NANA Towa Algrient, EFOLE Ewoukem Thomas, ZEBAZE Togouet Serge Hubert and Tchoumboue Joseph

In order to evaluate zooplankton biodiversity for the purpose of optimizing fish production in pond, the effect of doses of chicken manure was assessed from May to November 2016 in 9 ponds (5.7 x 5.7x 1 m) with a residual flow rate of 0.05 l/s. At each of the randomly selected ponds, one of the doses 0; 800 and 1000 kg / ha was administered weekly. The results showed that, nitrites (5.64 ± 0.19 mg/l), nitrates (6.23 ± 0.13 mg/l) were significantly (p<0.05) higher in pond fertilized at 1000 kg/ha, the opposite being observed with dissolved oxygen (3.53 ± 0.18 mg/l) and transparency (32.29 ± 2.50 cm). A total of 84 species belonging to rotifers (53 species), cladocerans (18 species) and copepods (7 species) groups were identified independently of treatment. The lowest values of zooplankton richness (21 species) were registered in the control pond, while the highest richness (59 species) was observed in the treatment 1000 kg / ha.
